Today, as you all must be aware of that tech giants are shifting most of their business over the cloud. Cloud is a pay as you go model which helps companies to expand their business as per their requirements which in turns helps them to cut their costs and increase their profits. Cloud provides other benefits too such as companies no longer have to worry about their hardware infrastructure which is now being taken care of by third-party companies such as Amazon Web Services, Google Cloud Platform, Microsoft Azure Services - the three tech giants in cloud services.Though I had heard of the various advantages of the cloud, my practical experience with cloud began in January 2021 wherein I had a semester course in my 3rd year of Btech(CSE) as Cloud Computing in Amazon Web Services.From there my journey of AWS Cloud started wherein our professors had from the very beginning of the course had made it clear that it would be really very beneficial for us to have a professional cloud certificate. I made my mind and prepared a plan from the beginning of February that by April end I should be able to crack the AWS Cloud Certified Professional Exam.Through this blog, I would like to share my preparation journey so that the readers could help from it and easily crack the exam. The exam is the easiest of all the AWS professional certificates and requires more theoretical knowledge of all the AWS cloud services.But I would highly recommend having practical hands-on experience on the AWS console too so that those theoretical concepts would stick better in your memory.For the practical experience, I referred mainly to two sources -My Semester Course ContentAWS ACADEMY COURSEI understand that everyone won't have an added advantage that I had in terms of practical experience since I had a semester course going on the same time but AWS Academy Labs along with the resources I am going to mention below would definitely help you gain a really good understanding of AWS Console and the cloud services offered by AWS.During February my main focus was to complete the AWS ACADEMY course as it is the official course recommended by the AWS in order to crack the AWS CCP exam. So I thoroughly went through it, made notes, attempted each lab and quizzes of the course wholeheartedly, and also explored the AWS console on my own. Though AWS services are paid you get a Free Tier for 1 year to have a hands-on and also AWS Academy provides you with a free playground to explore the AWS Console, though with limited services but enough for cracking the CCP exam. After the AWS exam, I referred to a free course on YouTube by freeCodeCamp.org (link I would be mentioning below), and at last, I referred to some practice questions. A word of caution, though CCP is a theoretical exam, I would highly recommend having an in-depth knowledge of all the AWS services because in the exam I noticed that the options were very closely related and didn’t resemble all with the quizzes in the AWS ACADEMY course wherein you could easily eliminate the choices.So overall I referred to these resources -AWS ACADEMY COURSEYouTube Course (freeCodeCamp.org - https://www.youtube.com/watch?v=3hLmDS179YE)Practice QuestionsI scheduled my exam for the last week of March as my midterms were about to start and I wanted to get away with the certification. Also by then, I was pretty confident that I would be able to crack the exam as one needed to score at least 700 out of 1000. I skimmed through the YouTube course again just before the exam to just get a refresher.For the exam, I scheduled it through Pearson and the proctor was a bit strict as he made me scan my entire room through my laptop’s webcam and also you weren't even allowed to utter or murmur during the exam.My result which stated that I had passed the exam came just after I submitted my exam and the official certificate came 2 days later.It feels really great to possess a professional certificate and with a continuous preparation of 2 months, I feel everyone could crack it and have a professional badge in their resume....

The first days were very hard and I did not understand much, but as time went I kept doing the 1st test till the 6th checking where I was wrong. The explanations made good sense and helped me understand better. There were new questions which is why I scored 810. It is much easier when you start with 1 test then the next and then start the exam mode when you understand the explanations.I studied on RNP for 2 weeks I think, then started testing myself with the prepway pdf which worked out well....

On the night of 14th January I completed my first goal of the year after I passed CKS. This was a little tougher than the previous 2 certs CKA and CKAD along with the fact that it was also fun to learn new tools while preparing for the exam. The exam will test your skills about how you secure your container orchestration architecture which is why it becomes so important that you should know this. For me I learn lot many new tools and concepts which will certainly help me in my cloud native journey.Prerequisites:You should have attempted & cleared the Certified Kubernetes Administrator(CKA) exam prior to attempting the CKS exam.CKS Topics:The best source of this information is thecncfofficial link. Please go through this before you start your preparation such that it gives you the basic understanding of the exam as well as the topics which will come in the exam.My guide to the preparation:As there is a famous saying “Practice what you know, and it will help to make clear what now you do not know” the same applies to Kubernetes and this exam. The more you practice the better you become. CKS is not just like any other certificate but a platform where you can learn lot new things. I was not confident that I will clear the exam but honestly I had enough practice which made me clear the exam in the very first attempt.I did enjoy preparing for the exam as it really helped me to learn new concepts and then practice accordingly. I can refer to these resources which can help you practice and learn in a quick time to appear for the exam:Killer Shell — CKS CKA CKAD Simulator: This is a very good simulator which will give you exam feeling and enough of time also to practice. You can get two simulators for free when you take the course onUdemy. Even though I referred lot many articles and my self study but I genuinely think that the course on Udemy from #Kim is enough to clear the exam.Certified Kubernetes Security Specialist 2021 | Udemy: This is also a new course launched by #Zeal on Udemy.Kubernetes Security Essentials (LFS260) — Linux Foundation — Trainingthis course from linux foundation is there which you can buy as a this has good exercises which will also help you while you prepare for the exam.Exam tips & tricksAs like any other exam of Kubernetes , you have to be fast enough. The exam duration is of 2 hours. I got 15 questions in the exam. There will be weightage on each question starting from 4% to 11%. Please read the questions completely before you attempt them. For me some questions were straightforward while for some I had to spend some time to understand them. Do not spend too much of time on one question, remember, you just need 67% to pass the exam :). Also, Ensure that you are on the right contexts before you start solving the questions.There are a few questions on which we will have to modify the files as per the ask. I would strongly advise to take a back up of the file before you start changing so that in case of a mistake you have the back up to refer to.I am not of the opinion to make too many aliases, but I would advise to make at least one alias which is k=kubectl. If you are comfortable creating aliases then go ahead and create as per your likings like kd=kubectl describe or kg=kubectl get , etc.I hope this will help you while you prepare for the exam. Feel free to reach out to me one on one in case you need any help.https://www.linkedin.com/in/shubhasis-mathur-14997064/...

Let me start off by saying that AZ-104certification examis not an easy one. You need to have subjectmatter expertise implementing, managing, and monitoring an organization's MicrosoftAzureenvironment.It goes without saying the responsibilities for anAzure Administratorinclude implementing, managing, and monitoring identity, governance, storage, compute, andvirtual networks in acloud environment, plus provision, size, monitor, and adjust resources, when needed.As per Microsoft, acandidatefor this exam should have at least sixmonths of hands-on experience administering Azure, along with a strongunderstanding of coreAzure services, Azure workloads, security, and governance. In addition, this role should have experience using PowerShell, Azure CLI,Azure portal, andAzure ResourceManagertemplates.Preparation Tips For The AZ-104 Exam I prepared for around 2 hours each day and on the weekend around 4 hours. Overall it took me around month and a half to complete all the course and the labs.Create a free account withAzureto get the $100, create your ownsubscriptionand use it for your labs. This is a must to get familiar with theServiceoffered by Azure.I would highly recommend to get familiar with the syntax of both theAzureCLI and AZ Powershell. If you're not too familiar with it, start with the basics like create a resource group, then a subnet, a VM and so on. If you do for few times, you'll have thebasisof the commands nailed down.Some of the questions are lengthy and tricky. You need to understand possible dependencies and where to spot them to be able to answer questions quickly. The practice exams really helped. Link here.My weakest area was "Configure and manage virtual networking". I would highly recommend creating Virtual Network (VNET), subnets, Network Security Group (NSG), Virtual Machine (VM), test RDP, install webserver, create allow/deny rules etc to make yourself familiar with the entire Azure VNET ecosystem.Another important lab is around You can use Azure Web App in your free account and play around with it. Expect to see multiple questions there.On the official Azure link it suggests to buy official practice test cost of which is $100. I wouldNOTrecommend buying that.I didn't get a lot of Kubernetes questions in the exam but I've heard some of my friends get not so easy questions there. Another important topic is Azure Active Directory. Check the list of topics below in the Official Exam Guide. I must have received at least 6-7 questions there. Some of the questions are lengthy and tricky. I would recommend to check them to be revisited at the end. If not sure of an answer, use the elimination process to get rid of options that are not applicable before making a guess. Azure Documentation has a lot of tutorials and quickstarts. While you do not need to go through all the tutorials but doesn't hurt if you really want to understand the Azure Cloud in depth.Good Luck on your exam....

Your Why is more important.Why choose PMI-ACP?Before I answer that, let me quickly take you through my Journey towards preparation of exam and exam experience.Preparation:I chose both online training classes and self study.I took the online training classes through knowledge hut. I felt I can take up exam in 45 days and paid for the PMI-ACP exam in February 2020. Started to prepare, Book used for reference:PMI-ACP Mike Griffiths.Due to so many reasons, the preparation was more or less like on and off and I could not take up exam as planned.**I am not going into details, but I had meantime every now and then tried my best to understand agile in general and agile mindset. I was asking so many questions to my friends who had prior experience in agile work environment and colleagues at my work place about why they do whatever do. All of it also helped to develop the agile mindset subconsciously.**Finally in November I decided to take up the exam. This time my approach was like, Week1: reading the reference book for 3 days continuously. Week2: Tried similar second iteration of 3 days of Continous study. Week 3: Gained the confidence about the flow, I scheduled the exam in a week and continued my preparation based on time left.Note: In the reference book, we have chapters and in the end of each chapter you had sample questionsI would have roughly studied the book 3 times. Honestly the 2nd and 3rd time, I skipped topics which I was comfortable about. tried the sample questions all the three times which helped me to decided which topics I can skip.Important Note: Sample questions are totally different from the actual exam questions.Final stage of preparation was trying out the Mock exams provided by Knowledge hut. I took two Mock exams and they were taken 2 and 3 days before the actual exam, it helps in two ways.(May be helpful tip for some, try taking these exams around similar time of a day compared to actual exam.Say you have exam on Wednesday at 9am, try taking the exams on previous week any day but around same time 9am.Why? I think, it helps to tune your mind)1. To assess your time management for the exam.2.To gain confidence about your understanding of Agile and Understand your mindset.As I already highlighted, please do not solely depend on these exams and also do not try to memorize the questions and answers because the actual exam questions are totally situational and it will test your understanding of Agile in general and Agile mindset.One tip before I move on to the exam section, please avoid preparing a day before the exam and on the day of exam.Keep yourself fresh and energetic, because believe me the exam will drain you out otherwise and you wont be able to read the questions with clarity. Especially the language used in the exam is not only tricky but also critical to know key words to be able to answer them. The day before the exam I slept nicely as I knew the importance of sleep.Online Proctored Exam:I took an online exam as it was convenient for me.(I would suggest others to go for it as well, provided you fulfill the needed requirements). I would advise as per the guidelines log in 30 minutes before the exam.Exam:The exam started and clock started ticking. Key take away here was. Although, I knew about it, I did what I should not have done. Got stuck to a question and soon realized the time was ticking.I almost ran out of time for last few questions.Some of the questions were short and some were long, so we may need to read 2 to 3 times both the questions and answers.Considerations for the exam:Be aware that in most work environment have tailored work process to suit their need, in exam focus will be on the plain-vanilla version of agile processes.self organization is highly valued in Agile.For some questions, It may help you to know the responsibilities of the people in different roles working in agile environment.while reading the questions considering time constraints its easily possible to miss out the key words in exam ex: which of these is "NOT"related to kind of questions.You must look out for the words that are against the Agile principles in the list of answers that help to eliminate options.Some questions, I was able to answer straight away, some needed to eliminate the options in the answers.Even then some places you will left with two probable answer options. Read the question again and see for the key word.You will then be able to find the best option.Now to important question, Why PMI-ACP?My dear PMI-ACP Aspirants, If you genuinely put in the effort to prepare for the exam, I am sure the journey for each one of you will be transformational not only career wise but also in personal life because of the minor mindset shift you will embrace subconsciously.Good luck for your exams, believe in yourself, you can do amazingly.Jagadeesh #Purity in thoughts and deeds....

Michael Jordan once said, “I can accept failure, everyone fails at something. But I can’t accept not trying”. I have failed my first attempt of PMP certification way back in April 2018. I was upset, disappointed and I thought of not going for another take. One day; I was going through my LinkedIn post; and saw a mutual friend of mine in LinkedIn who had posted he passed PMP certification in his third attempt. This caught my attention and I sent him a DM; “How to Study for PMP certification”. Believe me I am going to give you all the same advise what he had told me which helped me to pass the PMP certification with flying colors on my 2nd attempt ????1) Go through 35 Hours PDU – This will help you to refresh the concept of Project Management. Go for Weekend Classes; and make use of your Weekdays revising the concepts.2) Book the exam 1 month post the training. Students who give exam within 1 months has more success rate to clear the exam. The more you delay; more chances you may tend to forget the concepts you learned. You may be busy with other works and exam would be in queue forever. 3) Exam Outline: 200 multiple choice questions to be completed within 4 hours. Out of 200 questions, 25 Questions contains no marks (In your exam you needs to answer all questions; you won’t be able to know those 25 questions). Grades are given out as “Below Target”, “ Target” and “Above Target” on the 5 Process groups as depicted below:Initiating: 13% of questions are asked from this domain; followed byPlanning: 24% Executing: 31%Monitoring and Controlling: 25%Closing: 7%4) For any exam; you need to have a study plan. That’s my funda ????è Take a printout of the 49 Processes across 5 Process Groups and 10 Knowledge Areas. You will be tested on the exam based on the 49 Processes. My advice to you all is Never memorize the Processes; just go through the same every day and understand the concepts. Example: Why Scope management is required; if you know WHY; then the ITTO’s is easy.è Read once, PMBOK® Guide,Sixth Editionè Read the Rita Mulcahy’s o PMP Exam Prep (Ninth Edition) - It is very well articulated and guide to successfully complete the PMP exam, and be a better Project Management Professional.o Hot Topics (Ninth Edition) – Flashcards; It is a portable reference to be used to improve test-taking speed and information retention.

I started my cloud journey in 2019 when I heard so much about different cloud providers and I decided to start with Amazon Cloud.There were a lot of comparisons between AWS and other Cloud Providers I read on google and It made me go through different tracks of AWS. I completed my third and final AWS Associate level certification on 27th Sept 2020. The Preparation journey was a mix of patience and restlessness as I had scheduled my exam and somewhere I was feeling if I will be able to meet the deadline but I motivated myself and finally when I saw my exam result I found hard work always pay you back.Below are the steps I followed to prepare for this exam.I registered for my first training course onlearn.cantrill.io. I found the course content very nice especially the examples Author has used in the course to describe various AWS services.Once completed I attempted practice tests present in the training course and found the gaps in my preparation.My Second course was fromudemy.com. The Practice tests are very well explanatory and also linked to the course videos wherever required.Once I was set with the theory and practice assessments from training courses I decided to attempt mocks on the tutorial dojo. The Same course is also present onudemy.comFrequently asked questions on AWS are also very helpfulaws.amazon.comOther Exam StrategiesList down the use of AWS services during your preparation and compare them with similar services used for achieving the same functionality. One example isSite-to-SiteandAWS Direct ConnectMake Utilization of complete 130 minutes during your examFollow the approach of removing wrong answers based on the Keywords present in questionsMark for review those questions you are not sure about and come back later once you have attempted all the questions.Keep patience and stay calm.Crack the exam with flying colors.List of Services I found at most of the places in Real Exam1. RDS, DynamoDB, Aurora, Redshift: When to use as per availability, latency2. S3 bucket policies: The Examples were simple majorly on EC2 and DynamoDB3. VPC-Peering, Transit Gateway, Site-to-Site, Gateway Endpoint, interface endpoint: When to use and how to use. Which one is effective on the public internet and How to connect multiple VPCs and VPNs together4. AWS organization and SCP: How to restrict the access present with AWS Admin role6.

Hi,Before you go ahead reading the tips to score high, I would like to mention that I recently appeared for the AWS associate developer exam and scored 989 out of 1000. I would be sharing what all I did in terms of the resources, study materials and my experience that can stand helpful in your preparation journey.First & foremost I would like to tell you that if you are directly jumping to the AWS Developer exam without having any prior knowledge of AWS & its different domain and services then you would have a lot of confusions, unclarity & difficulty to understand the concept better that might affect your preparation and can go ununderstood or misunderstood along the journey which definitely you should restrain yourself from. As it is said, the AWS services are entangled with each other, so I would suggest going through the AWS Solution architect associate course once. That would provide you a holistic view of AWS, its domains, services and help you get much more clarity, understanding and a good overview to get started with the next step of the developer`s journey on AWS.As far as the resources and study materials are concerned, so I took the "AWS Developer Course" of Stephane Maarek on Udemy & practice test of Jon Bonso(Tutorials DOJO) on Udemy for the same. For revision purposes, Stepahe provides the link in the course's resource section to download the PPT that he uses while teaching and its a good to have one shot view of the important points in the context. I emphasize to attempt the test series of Jon Bonso because it helps you identify the calculated pace of understanding the question correctly and answering accordingly. The difficulty level of questions in the test series is kind of similar to what you would encounter in the main exam. It also provides a descriptive explanation of each question that helps a lot in understanding the different scenarios & services. Apart from this, I do recommend going through the white papers of AWS and documentations of services if time permits.Important to note that the developer exam has more weightage for AWS serverless stack & dev tools comprising of Lambda, DynamoDB, API gateway, SAM, S3, CI/CD, ECS, X-Ray, etc other than the rest of the services, so pay a bit more attention to these.I would like to reiterate what Stephane says and that is "not to take this learning or exam as a race" rather take your time, explore, learn and understand it thoroughly. If you don't understand the concept in one go, don't worry sit back relaxed and revisit it again and it would make sense eventually. Last but not least, don't study just for the exam but to get equipped with the cloud knowledge with in-depth insight of AWS & its offerings.I hope this would be helpful and I wish you all the best!...

So, for all of you who booked the Free version of OCI Cloud Operations Associate Exam (last month when it was Free), the very first email from PearsonVue said the time was 105 minutes. This is same as what is listed in the original Exam Preparation Guide as well as shown below in the screenshot –However, much to my surprise when I received the reminder email from Pearson it said 85 minutes. I thought it was an error and ignored it but when I started with the test, the actual time was 85 minutes. I believe Oracle is now testing based on the new exam guidelines. So, beware of this that you will get only 85 minutes even if you booked an earlier version of the exam. I was able to finish the exam on time.I did a quick comparison of the old and new exam guide in the OCI Learning path link and do not see much difference in the new format. So, hopefully no need to panic there. The total number of questions is 60 and passing marks are 70%.Before I start with the tips, this is the feedback from the exam once it was done:So, here are my preparation tips for you to pass this exam:It goes without saying how important the lectures are in the OCI learning path. However, if you just rely on the lectures you WILL NOT PASS THE EXAM.I honestly feel the lectures could be improved and made better, specially the labs which sometimes are very cut and dry. So, make sure you at least are spinning up an instance in the OCI console using a cloud init script. Here is a good blog on Oracle website if you are interested in learning more.Terraform – An important topic for the exam. Remember that you can use OCI Resource Manager for provisioning and management activities. Learn more about stacks, jobs, plan, apply, refresh, Rollback/Forward.Know when to use Ansible vs Terraform.Policies – A very important topic. You should know the syntax of the policies and know how and where to apply them – compartment, instance, dynamic group, groups etc. Also, what happens when to the policies when you move resources from one compartment to the other. I believe Rohit Rahi’s lecture in Associate Architect does a good job at explaining compartments and policies. Do a quick refresher of that.CLI Commands for object storage, compute instance. I believe I got at least 4 questions on CLI commands just for object storage. Example includes move to different region, delete object.Traffic management Service and Steering policies. You will see a couple of questions from here. Make sure you look at the console and remember the types of policies – Failover, Load Balancer, Geolocation, ASN, IP Prefix. Alarms – Go to the console and set up the alarm. Few questions on alarms that you will definitely see in the exam. Important note – If the alarm is triggered and you are getting constant emails from the Alarm, turn off the alarm before troubleshooting.Monitoring Query Language (MQL) is another topic that I believe I saw couple of questions. Bare minimum - remember the syntax of the MQL.Budgets – Again a very important topic. I got few questions on the usage of Cost Tracking Tags. Again, a good idea to go to the console to set up the budget.I got a few questions on the networking side of it to figure out what is not working. So familiarize yourself with Security Lists, NSG, how to write rules (ingress/egress).Read the Rules Of Engagement for Oracle Cloud Security Testing Policy. You might see a question or two here.A common theme for all OCI exams I’ve taken is backup and recovery, high availability, cross region copy. Expect few questions here.Console connections is discussed in one the lecture and it is important to note that these enable you to remotely troubleshoot malfunctioning instances. Read more here.Finally Audit Logs and Audit events.Final Tips:Go through my Flashcards (OCI Operations) that I prepared for this exam. If you are not clear on any of the card, please go through official documentation on OCI website.Take both the practice exams in learning path and besides knowing the right answer, know why the answer is rightTake the Associate Architect Practice exam again for that extra practice.Use process of elimination to narrow down on the answer if you are not sure. It is better than blindly selecting the answer.Mark the questions for review later if you are not sure of the answer. Sometimes you might get the right answer in the related subsequent questions.Important Links:Slide DeckLearning PathCertification DetailsExam Prep...

However, I have tried to put document most of the information from the professional exam perspective. Also, as you understand the different OCI services please make an effort to determine –1. The scope of the service as it is provisioned/launched – region/zone/global.2. The operating ability of the service as if it is moved to a different compartment and the effect of the IAM policy attached to the service or IAM policies attached to users operating the service.3. Review information contained in links attached to the documentation below.Please review following blogs that you may find helpful if you have not completed the associate architect exam –· How to prepare for OCI 2019 Architect Associate exam· Tips on how to pass OCI Architect Associate ExamPlan, design, implement, operate & Migrate On-premises workloads solutions in Oracle Cloud Infrastructure (OCI) Networking and Compute· Configuring Compute QuotasCompute Quota allow administrators -a) To allocate resources to compartments using the OCI console. The allocation is controlled by set, unset, zero commands. The IAM policy references help manage the quotas.b) To control how resources are managed using policies in OCI.c) Effective cost management by controlling allocation of resourcesCheck resource quota & policies for more information.· Instance Pools - Instance pools allow users to provision and create multiple Compute instances based off the same configuration, within the same region.· Instance Configurations – are used when we want to create one or more instances in an instance pool.· Compute Instance Metrics - monitor the health, capacity, and performance of yourComputeinstances by usingmetrics,alarms, andnotifications.· Compute Instance autoscaling configurations - With autoscaling you can adjust the number of Compute VM instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.· Instance console connections – enables you to remotely troubleshoot malfunctioning instances.· Custom VM Images in OCIo Managing Custom Imageso Bring your own Imageo Image Import/Exporto Image Import Modes§ Emulation§ Para-Virtualized§ NativeMost newer OS versions support para-virtualization launch mode as they provide maximum performance. All older OS versions can be launched using emulation mode that provides fully emulated NIC, block boot and legacy BIOS boot.· VCN Route Tables & Route Rules - OCI VCN uses virtual route tables to send traffic out of the VCN (for example, to the internet, to your on-premises network, or to a peered VCN). A route rule specifies a destination CIDR block and the target (the next hop) for any traffic that matches that CIDR. Here are the allowed types of targets for a route rule:Route RuleDetailsDynamic routing gateway (DRG)For subnets that need private access to networks connected to your VCN· Connect your on-premises network connected with an IPSec VPN or FastConnect,· Connect to another VCN via a peered VCN in another region.Internet gatewayFor public subnets that need direct access to the internet.NAT gatewayFor subnets with instances that do not have public IP addresses but need outbound access to the internet.Service gatewayFor subnets that need private access to Oracle services such as Object Storage.Local peering gateway (LPG)For subnets that need private access to a peered VCN in the same region.Private IPFor subnets that need to route traffic to an instance in the VCN. For more information, see Using a Private IP as a Route Target. Also see Advanced Scenarios: Transit Routing.· OCI Load Balancing – It is imperative to understand load balancing concepts, public & private load balancers and policy types (Round Robin , Least Connections, IP Hash) supported by the load balancing service.· OCI DNS & Traffic Management· Advance Networking Scenarios.· FastConnect with multiple DRG’s and VCNs.· FastConnect Connectivity Options· High Availability & Disaster Recovery in OCIPlease see IAM policies for networking. Storage Options· Local NVMe SSD devices – These devices act like instance store volumes attached to compute instances in your VCN.· Block Volume Storage - The OCI Block Volume service allows to dynamically provision and manage block storage volumes. We can create, attach, connect, and move volumes, as well as change volume performance, as needed, to meet our storage, performance, and application requirements.o Volume Groupso Attaching a volumeo Attaching Volume to multiple VM instanceso Volume Resizingo Block Volume Backupso Block Volume Performanceo Moving Block Volume across compartments· File Storage - OCI File Storage service provides a durable, scalable, secure, enterprise-grade network file system.o Create a file systemo Managing a File Systemo Mounting File Systemo Managing Mount Targetso Troubleshooting File Systems· Object Storage - OCI offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" - Object - storage, and less frequently accessed "cold" -Archive - storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.o Object Storage Namespaceso Managing Objectso Managing Bucketso Object Storage Life Cycle Managemento Using Pre-Authenticated Requestso Using Multi-Part Uploads OCI Account Management· Billing & Cost Management· Cost Analysis Overview· Billing & PaymentsDesign, implement, and operate databases in OCI· Autonomous database concepts – Autonomous databases are fully managed, preconfigured database environment with two workload types available, Autonomous Transaction Processing and Autonomous Data Warehouse.o Autonomous database deployment optionso Using Autonomous data warehouseo Using Autonomous transaction processing databaseo Security & Authentication in Autonomous transaction processing databaseo Autonomous database complete overview & best practiceso Using Oracle DB CLIo Incorporating high availability with Oracle Data Guard for bare metal & VM DB Systemso Incorporating high availability with Oracle Exadata DB Systemso Recovering Oracle Exadata DB Systems from object storageo Database Migration Options to Oracle CloudMigrate on-premises workloads to OCI· Data Transfer and Storage GatewayDesign for Security and Compliance· Using Oracle Data Safe - Oracle Data Safe is a fully-integrated Cloud service focused on the security of your data. It provides a complete and integrated set of features for protecting sensitive and regulated data in Oracle Cloud databases.· Using OCI Identify & Access Management· Using OCI Key Management· OCI Security Overview· OCI Traffic Management Policies· OCI Web Application FirewallAdditional Useful Services· OCI Events· OCI Kubernetes Service· OCI Functions· OCI Monitoring Service· OCI Resource Manager· OCI Vault· OCI Notifications Service· OCI Streaming Service· OCI Tagging – Ensure that you understand the differences between using cost tracking tags, tag variables, tag defaults and predefined tags.· Using Oracle Golden Gate - to replicate, filter, and transform data from one database to another database.I added the last section above because the Oracle training for professional architect did not review the usage and applicability of these services, however, there were questions around them in the exam. I have added my notes below from the exam perspective –· Most of the questions in the professional exam are around the basis concepts so it is imperative you have reviewed these links and understood them.· As usual while answering any questions, you always need to look for special catch phrases or words that contain latency, performance, cost, high availability, redundancy, maximum availability modes for no data-loss etc.· While connecting from Oracle VCN to managed service like object storage and ensuring that the traffic does not traverse the public internet – the only service that can be used is service gateway. Please review the service gateway service gateway supported Oracle cloud services in OCI network.· While establishing console connection, please remember that three tasks are required before you can connect –o Reboot the instance from the OCI console.o Add or reset the SSH key for the opc usero Edit the system configuration file at the linux boot menu to enable access to the console.· Deep dive into NVMe performance differences while using a particular RAID configuration. A protected RAID array is the most recommended way to protect against an NVMe device failure. RAID 10 Stripes data across multiple mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved.· WAF Access control rules can be used to block specific IP addresses from making unauthorized application requests.· Review available connection options from OCI to other cloud providers like Microsoft Azure.· Managing Compartments and moving resources between compartments is one of the most important features that had few questions related to them. During movement of compartments, some of IAM policies attached to the resources are not automatically updated. This is the reason to validate the IAM policies after compartments movement from one parent to another.· OCI File storage service (FSS/NFS) provides export option feature to control access to your file system.· VCN peering is a widely used feature considering that the VCNs are regional and you use local VCN peering for within region pairing or remote VCN peering for across region VCN connections.· You may encounter compartment quotas limitations defined by quota policies during auto scaling actions. This may lead to system failures.· Review that there are three ways to connect to ADW -o Connecting to (ADW) from Public Interneto Connecting to ADW (via NAT or Service Gateway) from a server running on a private subnet in OCI (in the same tenancy)o Connecting to ADW (via internet Gateway) from a server running on a public subnet in OCI (in the same tenancy)· You may encounter some questions to be not as detailed about compartment moves. So, you may see a question about moving compute instance across compartment. However, it may not be clear if the instance is moved to a compartment defined in the same region in the same VCN or across a compartment in another region. So, please do not overthink the scenario (Which I did). An instance with public and private IP that is moved to a different compartment will continue to have its original public and private IP addresses. The instance VNIC also continues to be associated with the original VCN.· Autonomous Database is an Oracle Managed and Secure environment. A physical database can’t simply be migrated to autonomous because:o Database must be converted to PDB, upgraded to 19c, and encryptedo Any changes to Oracle shipped privileges, stored procedures or views must be removedo All legacy structures and unsupported features must be removed (e.g. legacy LOBs)· GoldenGate replication can be used to keep database online during migration.· Oracle also recently introduced instance principals that now eliminates the need to configure user credentials on the services running on their compute instances, or rotate those credentials. Instances themselves are a new principal type in IAM.· A Dynamic group is a special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group.· STEERING POLICIES is A framework to define the traffic management behavior for your zones. Steering policies contain rules that help to intelligently serve DNS answers.o FAILOVER - Failover policies allow you to prioritize the order in which you want answers served in a policy (for example, Primary and Secondary). Oracle Cloud Infrastructure Health Checks are used to determine the health of answers in the policy. If the Primary Answer is determined to be unhealthy, DNS traffic will automatically be steered to the Secondary Answer.o LOAD_BALANCE - Load Balancer policies allow distribution of traffic across multiple endpoints. Endpoints can be assigned equal weights to distribute traffic evenly across the endpoints or custom weights may be assigned for ratio load balancing. Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of the endpoint. DNS traffic will be automatically distributed to the other endpoints, if an endpoint is determined to be unhealthy.o ROUTE_BY_GEO - Geolocation-based steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region.o ROUTE_BY_ASN - ASN-based steering policies enable you to steer DNS traffic based on Autonomous System Numbers (ASN). DNS queries originating from a specific ASN or set of ASNs can be steered to a specified endpoint.o ROUTE_BY_IP - IP Prefix-based steering policies enable customers to steer DNS traffic based on the IP Prefix of the originating query.· OCI also provides an option to resize an instance using change shape feature in the OCI console.· Autonomous transaction processing – serverless database option is not available for Oracle enterprise business suite.I want to add a few tips from my experience during the exam –§ I noticed most of the answers are in the question, so if you are not completely confident, select what you think is right, mark the question to come back for review and then revisit it as soon as you are reviewing your exam.§ You will notice as you traverse through rest of the tests, some of the questions that follow latter may also have answer to what you could not answer earlier...

PrerequisitesThe AWS Database exam blueprint recommends that examinee’s have at least 5 years’ experience with database technologies and two years’ experience working with AWS. You should be familiar with open source SQL and NoSQL databases.In addition, I advise you have at least AWS Associate Developer or DevOps Professional certificate before taking the exam. This would make it easier to answer questions on deployments and monitoring.PreparationI went through all the material prescribed in the ramp up guide. These included courses on AWS training website, user guides for all AWS purpose built databases, whitepapers and AWS Databases blog posts. I also watched re: Invent videos on DynamoDB, Elasticache, QLDB, Redshift and DocumentDB.As part of preparations, I also used practice tests and video courses on DynamoDB and Migration from Whizlabs. I wrapped it up with the practice exam from AWS (20 questions).General OverviewRDS and Aurora are the most tested products on the exam. These products account for 50-60% of questions on the exam. You should know the architectures of both RDS and Aurora. Features that both share and those that supported by only Aurora. DynamoDB and DocumentDB may account for about 20% of the questions. All other purpose built database products account for the remaining questions.Before you take the exam, you should know how the following services work on AWS: VPCs, Security groups, IAM, CloudWatch, Cloudformation, CloudTrail and S3.Even though the exam is theoretical, experience with the purpose built database services on AWS should guarantee success.Exam Domains1 Workload Specific Database designThis section requires you to understand all AWS database offerings and their use cases.You should consider the following for the exam:· One size does not fit all. There is a database solution for every type of workload. The exam tests you on choosing the right database for the given scenario.· RDS (5 engines), (PostgreSQL and MySQL), Aurora, Redshift, Elasticache (Redis and Memcached), DynamoDB, DocumentDB, Keyspaces, Neptune, Timestream, QLDB are the Database offerings tested on the exam.· The architectures of all the database offerings. Understand how to implement disaster recovery and high availability when using these services.· Understand how these services are charged, their performance (latencies) and best practices in securing data.Pro tip:· RDS and Neptune use the multi-AZ architecture.· Aurora and DocumentDB use the shared volume architecture. Aurora supports global databases, DocumentDB does not. Compute is separated from storage and hence both are scaled differently.· DynamoDB supports global multi-write (hence gives low latency reads and writes). Aurora Global databases support only one writer endpoint. Aurora Multi-Master databases are regional not global.· Aurora Serverless databases are best suited for development and can shut down when there are no reads or writes.· DynamoDB, Keyspaces and QLDB are serverless.2 Deployment and MigrationConsider the following for the exam:· How to use Cloud Formation for deployments. Understand drifts, stacks, stack sets and change sets.· You should be familiar with the roles DMS,SCT and WQF play in migration· You should know when to use native migration tools, their limitations and which tool to use for which migration task· How to migrate LOBs· You should know which databases support cloning and when to use Aurora read replica to migrate a database· You should be know how to validate migrated data.· When to use snowball or Direct connectPro Tip:· Oracle handles null and time zones differently from PostgreSQL.· DMS is used for online migration (slow but minimizes downtime), native migration tools are used for offline migration (quick but causes downtime). You can combine both native tools and DMS (CDC) for the best of both worlds.3 Management and OperationsThis section tests your ability to perform everyday database management activities.You should know the following for the exam:· Automatic/continuous backups and manual backups· Backup and maintenance windows· Considerations for minor and major engine upgrades· How backups, copying/sharing snapshots and read replicas meet RTO and RPO objectives· Parameter Groups and Option groups (permanent and persistent options)· How to Secrets Manager works with Databases· When changes are applied – rebooting instances or maintenance windows. How to applying changes immediately.· When to use DAX and Elasticache· When changes are applied – rebooting instances or maintenance windows. How to applying changes immediately.4 Monitoring and TroubleshootingThis section tests your ability use AWS services to monitor workloads and troubleshooting common database issues.You should know the following for the exam:· CloudWatch, CloudWatch Logs, RDS Events, Performance Insights, CloudTrail , Enhanced Monitoring , CloudWatch Application Insights for .Net and SQL Server and Trusted Advisor· Basic troubleshooting for the database offerings· Best practices for each database engine.· Read about IOPS, Tuning queries, Secondary indexes, TTL, sharding, Read Replicas etc.5 SecurityYou will find questions on securing database workloads on AWS.You should know the following for the exam:· KMS – which services use AWS managed keys and CMKs. Disabled/Deleted keys and their impact on workloads. Key rotation· · How IAM integrates with the various database products and how IAM DB Authentication works. Understand which services support fine-grained access control and those that do not· Data in Transit – How to enforce data encryption on each RDS engine. Data in transit for all other database offerings· VPC endpoints, VPN and Direct connect· Private subnets, NACLs and Security Groups· How to auditing works for different database products· Security controls supported by the different database enginesLinks to Resources usedAWS Ramp-Up Guide: Databaseshttps://d1.awsstatic.com/training-and-certification/ramp-up-guides/RampUp_Databases_2182020.pdfExam Readiness: AWS Certified Database – Specialtyhttps://www.aws.training/Details/eLearning?id=47245AWS DynamoDB Deepdive –Beginner to Intermediate ($5)https://www.whizlabs.com/learn/course/aws-dynamodb-deep-dive-begineer-to-intermediate/Database Migration to AWS Masterclass ($5)https://www.whizlabs.com/learn/course/database-migration-to-aws-master-class/Practice Tests - 145 questions ($20)https://www.whizlabs.com/learn/course/aws-certified-database-specialtyI did it in two weeks, you can do it too.

I have taken almost 3 weeks to prepare for my first AWS Cloud Practitioner exam.Sources :First started with acloudguru cloud practitioner course and as the exam date gets closer, I have used Andrew Brown's Ad Free youtube video which helped me to get clarity on differences & use case between similar services, for eg., Cloudtrial vs CloudWatch, Inspector vs Trusted Advisor and etc). Followed by 6 practise test in Udemy and note, you may feel the practise tests are so difficult but actually not compared to actual AWS exam, if you score around 80% consistently in practise tests. I would say anyone is good to take the exam.Personal Experience :I actually started taking acloudguru course during Feb 2020 end and I dropped after few sessions. I have always been a person who needs something to make things serious, So one fine day in May, I said myself, its not working out, So I decided to schedule my exam first and then prepare seriously for it. It hardly took me 1 Week, scheduled exam for May 30th and started learning during memorial weekend Saturday May 23rd.Currently preparing for AWS Solution Architect and in fact, have scheduled my exam :)Wish you all good luck. Please get in touch (bvmindsblogs@gmail.com) if you need any assistance with preparation for cloud practitionerThanks,Boopalan...

Adobe Experience Manager(AEM) is a Sling/OSGI based enterprise grade content management system which is one of the most sought after CMS in Fortune 500 companies.AEM was earlier know as Day CQ or DayCommunique and was acquired by Adobe. Since then the product has evolved by leaps and bounds and is now one of preferred choice for top brands to implement their digital properties and integrate it with personalisation and marketing automation engines.You can get the details around AEM architect certification here:https://spark.adobe.com/page/t8ASQanIS7sFg/AEM Architect exam test your on following areas of the product:Understanding client requirements and converting them into a technical solution design.Architecture & DeploymentSecurityPerformanceSolution DesignIntegration with external systemsMulti country/ Multi Tenant/ Multi Region/ Multi language deploymentsSomeone who has been working on AEM for sometime should know most of the above mentioned areas. These are basic principles of implementing any enterprise level web project and AEM is no different.The difference however is how to achieve the above said principles using AEM architecture which is slight different then other traditional CMS as it has a 3 Tier infrastructure to actually serve content to the end user.I read through the topics listed here:helpx.adobe.com, it took me approx 40-45 days to cover most of the topics as the documentation is quite detailed.Main topics that one must know to attempt this exam are:AEM Deployment Patterns.(Very important)TarMK vs MongoMk.(Very important)FileDatastore vs S3Datastore.User management - includes authentication using external IDP and syncing user/groups to AEM repository.Search & Indexing.AEM maintenance and OAK repository concepts. Example - Online vs Offline compaction, version purge, audit log purge etc. (Very important)Performance tuning using code structuring like using clientlibs etc.Load balancing & Security using dispatcher configurations (Very important) Spend some time implementing the things you read on your own by setting up servers locally. You can also look through your current project implementations to get deeper understanding of AEM concepts.Exam details:60 questions120 minutes60% required to clearCan be taken onsite or online proctoredI will not recommend you to take this exam if you dont have enough AEM architecture experience(It's quite expensive at $180) as most of the questions are quite specific to AEM architecture and how you will handle certain client requirements.For more details, please write to me directly, I will be more then happy to help you guys.CheersRaman...

I passed my CKA exam recently and had a great time preparing for it. I cleared the CKAD a week before. In September, the CKA is getting an update. It totally depends on you which one you want to take. You are going to be awarded the same certificate.Timeline:Started with Mumshad's course on CKA in mid-April.I finished the course in 3 weeks then started studying for CKAD. Many topics in CKAD overlapped with CKAD so I managed to finish it in about a week.Booked the CKAD for 2 weeks from the day I finished the coursePracticed for 2 weeks using Mumshad's practice test and Labs, Linux Academy practice test, also found some useful free labs on the Kubernetes.io website with KataKoda playground.I also used KodeKloud's game of pods for improving my Kubernetes concepts.Exam Info:Time: 180 minutes ~ 3 hoursPrice: $300Total no of Questions: 24Tips for Exam:1. Use alias and autocomplete for aliasalias k=kubectlcomplete -F __start_kubectl kYou can also make custom aliases for your ease. I made aliases for common commands that I knew I will be using a lot definitely.These were, alias kg='kubectl get pod' alias kga='kubectl get pod --all-namespaces' alias kc='kubectl create -f' alias kd='kubectl delete -f'NOTE: if you ssh into another node, these aliases won't work2. Use documentation effectively. This is where solving problems from the mock tests will help you. The answer to your questions are given in the documentation, you just need to know where.3. Use the --dry-run command. This command is used to check whether your command is correct and if it is you can use -o yaml flag to get the yaml code for the component and store it in a YAML file.4. The exam uses the latest version so better if you read the latest documentation as the courses I have mentioned use bit old versions of Kubernetes.5. In the exam, there will be multiple clusters like k8s,n8s,d8s. There will be commands to change clusters. First, read the question and see which cluster it is working on and if it is different then copy and paste the command from the question to set the cluster. A precautionary method will be to copy-paste the command for every question if you don't know which cluster you are on.6. Try to use imperative commands to create resources. Practice will help you in knowing what can be done through commands and what cannot be done.7. I suggest attempting the troubleshoot and managing clusters in the end after you are done with other questions as they take a lot of time.8. When you ssh into a worker node, Kubectl may not work. So use docker commands to see if the containers are up.9. Practice troubleshooting well and remember that in the exam the changes made during troubleshooting and installation are permanent and you cannot revert back to the state it was before you attempted the question.10. In case you need to delete and recreate any Kubernetes resources, store a backup in case you mess up you can revert the changes.11.Know where you are in the cluster. Some questions require you to ssh onto different nodes. When you do sudo -i on the node you need to logout twice to return to the previous node.12.Use Kubernetes cheat sheets from Kubernetes docs they have a lot of commands that are helpful. You can search for cheat sheet in the search box and goto first linkBonus:I have created a Kanban board to help students out in their CKA/CKAD journey. For people unfamiliar with Kanban. It is a board with a number of columns. Each column shows the state of each task. Most famous is with 3 columns: Task/Todo, Doing, Done. You pick a task you like and you drag it and put it in doing column and start doing the work. When you are finished you pick up the task and put it in the done section. I have added useful links in the description as well as tips for clearing the exam. Here's a preview of how the Kanban Board looks. Sign up for free and start using it. Click on "Create a Board from Template".This board has all the resources you will need to clear CKA/CKAD. LINK:Click here to get startedSome FAQs:Q. Can I access Kubernetes documentation in the exam?A. yes you can but there are links leading outside of kubernetes.io and you must not visit them. You are also given a notepad in the environment to make notesQ. Are partial marks awarded for completing 1 step?A. Possibly, as I completed 81% worth marks correctly and had done partial completion of 4 other questions worth 19 marks. I got 85% total which makes me conclude that yes they do award marks for steps.Useful Links:CKAD COURSE UDEMYLinux AcademyGame of PodsTrello Kanban Board...

I started off my cloud certification journey with the AWS Solution Architect Associate exam in Dec 2019.After a while, I shifted my focus to Azure, considering its market presence in UAE, especially in Dubai. I may be wrong here.I started reading Azure fundamentals in Microsoft Learn for about 2 to 3 weeks to familiar myself with services offered by Microsoft Azure. While doing so, i always used to compare with AWS services, because almost all the services are similar in both providers which means, bringing value to the customers.After I got myself comfortable with Azure fundamentals, instead of writing the AZ900 exam, I made a bold decision to appear for the AZ300 exam. Then, I started following the course contents for AZ300 in Microsoft Learn at a high level to gain more insights into the various services offered by Microsoft. I have used Scott Duffy's course on Udemy website for AZ300 and watched all his videos. The key to success is, to practice the concepts at the end of each topic/video to get myself comfortable with the services.Next comes, the practice exam with time-bound preparation. So, I purchased a practice exam from Whizlabs website. After each exam, I spend more time going through the explanation for both answers and wrong answers to gain more understanding on the questions and scenarios.Finally, after 2 months of preparation, I booked the exam on 18th April 2020, and cleared on the first attempt.Then comes, the AZ301 preparation. I must admit that AZ301 is pretty easy compared to AZ300. This is my view.I spent 2 weeks preparing for AZ301. Firstly, I purchased Nick Coyler's course on Udemy website. Gone through all the videos and followed my practice on free subscription. Secondly, purchased the practice exam on Whizlabs. Did the same exact thing as I did for AZ300.I booked the exam on 8th May 2020, and cleared on the first attempt.Wish you all the readers a happy learning and good luck for your preparation....

Certifications on Cloud Computing Fundamentals – Triumvirate: AWS Certified Cloud Practitioner, Microsoft Azure Fundamentals, Oracle Cloud Infrastructure Foundations 2020 Associate. I completed the Fundamentals on the 3 major Cloud platforms in order to understand the basics of what the platforms offer. Given many of the fundamentals are alike, it is also helpful to clear the exams close to each other , as you can slice off some of the preliminary concepts quite easily. I hope this will be a useful source of information. https://github.com/moulinath/Cloud-Certifications Exam # 1: AWS Certified Cloud Practitioner 1. Fundamentals - Given this was the first Cloud certification I was going for, I deemed it important to go through a full round of fundamental materials - The APN (Amazon Partner Network) courses were helpful for this. I went through Introduction to the AWS Cloud, AWS Architecture, AWS Core Services, AWS Integrated Services, AWS Security, Pricing and Support - I then went through a formal course on Udemy. There are of course many AWS CCP courses on Udemy and you can pick up any one. I completed the one imparted by Qasim Shah. Irrespective of your access to APN materials, it will be a good idea to go through a Udemy course as these courses are structured and most of them would provide you with a preliminary idea of the basics - At this point, I also got set up on AWS so that I could start playing around a little 2. AWS White Papers - Even though the Certified Cloud Practitioner exam is more on the Fundamentals, it will be very beneficial to go through the AWS White Papers. These are very informative and if you have experiences of Legacy Migration/Modernization initiatives, you will be able to greatly relate to these. And even if you do not, still very helpful. I went through all these White Papers multiple times - List of the White Papers that I went through (all of these are available on AWS site) : AWS_Cloud_Adoption_Framework, AWS_Pricing_Overview, AWS_Security_Best_Practices, AWS_Well-Architected_Framework, AWS-Cloud-Best_Practices, AWS-Migration-Whitepaper, AWS-Overview, AWS-TCO-Web-Applications, Change_Management_in_the_Cloud 3. Other Reference Materials - I went through the AWS CCP Training Notes offered by Neal Davis from Digital Cloud Training - A few Mind Maps hosted by peers in the Cloud Computing space. These are useful tools for last-minute look-ups 4. Practice Tests - The AWS CCP Practice Test program offered by Neil Davis on Udemy is an exhaustive one that I took quite a few times - One approach worth considering is to take the tests once very early into your studying phase – it will tell you where you stand. Then, as you take the tests multiple times, see which areas most of your knowledge gaps lie in. You can focus more on those in the days leading up to the actual exam - I also went through the AWS CCP questions on examtopics.com a few times 5. My Own Notes - I created a reference document for my own use (uploaded in Github) while I was going through the many sources as above. This helped me do a last-minute look-up. Exam # 2: Microsoft Azure Fundamentals 1. Fundamentals - I completed the entire Foundational Course for Azure Fundamentals on Microsoft Learn. This has 12 modules : Cloud Concepts – Principles of cloud computing, Create an Azure account, Core Cloud Services – Introduction to Azure, Core Cloud Services – Azure architecture and service guarantees, Core Cloud Services – Manage services with the Azure portal, Core Cloud Services – Azure compute options, Core Cloud Services – Azure networking options, Security responsibility and trust in Azure, Apply and monitor infrastructure standards with Azure Policy, Control and organize Azure resources with Azure Resource Manager, Predict costs and optimize spending for Azure - This is a structured course and really helps to develop a broad understanding. - I then took the Udemy course on Azure Fundamentals offered by Alan Rodrigues. This course in fact covers more on Azure than what you would need for the Azure Fundamentals exam. - At this point, I also got myself set up on Azure so I could explore some of the services 2. Microsoft White Papers - There is a huge amount of Azure documentation that you can go through on Microsoft site. - I focused on the ones on Architecture, Security and Pricing. I did also go through the high-level write-up on the Azure products and services - Given I went for Azure Fundamentals right after AWS CCP, I found the AWS to Azure services comparison pretty useful. You can just do a search for that on the Microsoft Azure documentation site. 3. Other Reference Materials - A few Mind Maps hosted by peers in the Cloud Computing space. These are useful tools for last-minute look-ups 4. Practice Tests - The Udemy Azure Fundamentals course by Alan Rodrigues that I took, had 2 sets of practice exams that were quite useful - I also took the Azure Fundamentals practice tests offered by Scott Duffy on Udemy. - I also took the Azure Fundamentals practice tests on Whizlab - I did also take the Azure Fundamentals practice tests on examtopics.com. Some of the discussions on the threads were quite useful 5. My own notes - I created a reference document for my own use (uploaded on Github) while I was going through the many sources as above. This helped me do a last-minute look-up - I did also create my own spreadsheet mapping of the AWS and Azure services (uploaded on Github) Exam # 3: Oracle Cloud Infrastructure Foundations 2020 Associate 1. Fundamentals - Given this is a new course that Oracle has come up with, there are not too many materials that are available on this yet - That said, the online training material conducted by Rohit Rathi from Oracle is comprehensive for the purpose of clearing this exam. I went through this material a few times 2. OCI White Papers - Oracle offers many comprehensive White Papers on their website. Obviously the materials around the database services are very strong. I did also find the following ones quite informative : OCI_User_Guide, OCI_Getting_Started, Cloud_MAA_Overview, best-practices-deploying-ha-architecture-oci, paas-iaas-pub-cld-srvs-pillar-4021422 3. Other Reference Materials - Not much available yet , unlike AWS and Azure - On medium.com, you can find one by Balaji Ashok Kumar who has done a very helpful job of curating notes from the OCI Online training program 4. Practice tests - The only one I could find when I was studying for this exam was the one comprising of 20 questions offered as part of the OCI Online training program 5. My own notes - I did curate module-specific notes from the OCI material. Would not be very different from the one I referred to, as published on medium.com by Balaji Ashok Kumar. Mine is a set of notes for the separate modules, his is a consolidated version. You might want to go through his version....

I recently passed the Certified Kubernetes Application Developer (CKAD) exam. I started my journey approximately a month and a half back in April. I started by watching Mumshad's course on CKAD on Udemy. It gave me quite a starting point. I liked his explanations of different complex topics.I used to dedicate 2 hours each day for the course. I finished the course in around 15th May and booked the exam for 29th May. For the 2 weeks, I used to practice using practice tests present in Mumshad's course. Soon, I finished them and I had nothing to more to practice or so I thought. Then I used Linux Academy's practice exams and labs given in their courses and they were quite helpful. Both of these courses were aligned with the exam and helped me a lot in passing them. I noted which sections I was weak in and went back to their specific Labs.Format of Exam:Click here to book the examThis exam consists of 19 questions that are needed to be solved on the Kubernetes cluster practically. This exam is 100% practical based. You can still open an additional tab for Kubernetes documentation.Total TIme: 2 hoursPrice: 300$Total Questions: 19Tips for Exam:1. Use alias and autocomplete for aliasalias k=kubectl complete -F __start_kubectl kNo need to remember it. The exam allows you to open an extra tab to visit kubernetes.io. Just type alias in the search bar in Kubernetes .io and visit the first link. It's all given in there. Sometimes the names of pod and namespaces are too long and using full command name will just make it look unreadable something like :Kubectl get deployment deployments.app mysql-buster-12414325235135 -n alpha-beta-gamma -o yaml > deploy.yamlusing alias kgd='kubectl get deployment -o yaml ' You can shorten this in the following mannerkgd deployments.app mysql-buster-12414325235135 -n alpha-beta-gamma > deploy.yamlYou can also make custom aliases for your ease. I made aliases for common commands that I knew I will be using a lot definitely.These were, alias kg='kubectl get pod' alias kga='kubectl get pod --all-namespaces' alias kc='kubectl create -f' alias kd='kubectl delete -f'2. Use documentation effectively. This is where solving problems from the mock tests will help you. The answer to your questions are given in the documentation, you just need to know where.3. Use the --dry-run command. This command is used to check whether your command is correct and if it is you can use -o yaml flag to get the yaml code for the component and store it in a YAML file.4. The exam uses the latest version so better if you read the latest documentation as the courses I have mentioned use bit old versions of Kubernetes.5. In the exam, there will be multiple clusters like k8s,n8s,d8s. There will be commands to change clusters. First, read the question and see which cluster it is working on and if it is different then copy and paste the command from the question to set the cluster. A precautionary method will be to copy-paste the command for every question if you don't know which cluster you are on.I hope that was helpful to you.

Hello All,This is Sanjib Behera, currently having passed 4 AWS certifications (all 3 Associate(s) & Practitioner), 1 GCE certification, 1 OCI Foundation certification & 1 Azure fundamentals certification. and to be honest 14 days are not enough to pass any cloud exam. First of all, I have the advantage of working in AWS projects from last 2 years, so I have worked extensively on few services like EC2/CloudWatch/VPC/S3/RDS/Cloudformation etc. I had loads of handson for this AWS Developer certification using CLI/SDK during the last 14 days(Most of them sleepless nights), it was all worth it at last. Additionally, I also have my AWS free tier account and have extensively worked on Lambda using SDK(boto3). I also work on IAC tools like Terraform & Cloudformation for spinning up AWS resources which gives me very good perspective.Although I do not work on all AWS services i.e. required to have knowhow to get pass this certificate,I started reading for this exam from 11th May via the Stephane's Udemy course for Developer Associate exam, as I like his tutorials and was parallelypracticing via the CLI & SDK(boto3/python). My main focus area was to practice coding with simple scenarios using python SDK and play around the API calls via boto3 SDK especially for the services like EC2, DynamoDB, S3, RDS, ElastiCache, ECS, SQS etc.As I have my AWS free tier account, hence in the past I have played around the AWS Devops Service(s) extensively ie. CodeCommit/CodeBuild/CodePipeline/CodeDeploy/CodeStar. Also I run some personal Devops workloads in my laptop where I use Jenkins as CI Tool and collaborate (CodeCommit, ECS, ECR, CodeDeploy) Jenkins plugins in some of the pipeline jobs. So all these experiences helped me answer all the questions related to the Devops area in my exam.Stephane Tutorial helped me in all those services, which I have never worked with like Elastic Beanstalk/SAM/Cognito/Api Gateway/Kinesis/X-Ray etc. I personally recommend his Udemy tutorials should be taken for this certification and rest AWS certifications as well. Okay so as I didn't had experience in the above mentioned services, hence I first watched the tutorial by Stephane and then I again practiced these services on my AWS account. Handson was pretty important for me, it was not only to get passed but to learn them quite well since my next target is the 2 AWS professional certificates.We need to learn the services API's, of all the services which I have mentioned above, next is IAM roles required by the services (for example if Lambda only requires to read S3 bucket, which managed role is required by Lambda and so on and if you are required to create inline roles, you must know how to create them or have an idea about it) and also there will be many security questions. I did not faced any questions where there was code given in the exam. Most questions were API centric, hence it is important to know what each API does and what purpose is solved by it? AWS always tries to trick you with 2 similar looking answers, but having good handson and you know about the service quite well and if you read the question well, you immediately know which of the 2 is the correct answer. Like for example if you know about DynamoDB LSI and GSI and their usecase, you can easily crack the question where both of these DynamoDB features will be given as answer options and hence if you read the question and understand the requriement well, you can select between the two.Last but not the least, as this is developer certification, the deployment options, its use case and scenario which one is to be used in which usecase, it is very important to understand, I got around 6 questions on this topic and again having the knowhow helped me to crack all these questions.So this is it , daily dedicated sleepless 8 hours for 14 consecutive days after having dinner.So this is my journey to pass the AWS Developer Associate Certificate....

At the mid of 2019, I was just a user of AWS services without any deep knowledge of how things should be correctly configured. The company that I work for had some web solutions hosted on EC2 instances, but as you may know cost handling at AWS even for a newbie is a true myth so you can't miss with it incautiously as it would cost you too much that you may not afford to pay.I determined that I need to learn how it should be done. So I looked at the various tracks and certification paths and found that the most suitable one according to my current career is the Developer track specially as I am really interested about Devops.Actually it took me about 3 months from starting the preparation course till taking my exam. I think it's a bit too much but it was due to my full-time job timeline limitations.Getting to the preparation strategy I followed:I got the foundational information about AWS services, use cases and hands on from Stephane Maarek courseAWS Certified Developer Associate at Udemy, it's really great and concise course with many hands-on and hints about critical tricks and also very useful tips. The one cons about the course is that, It was a bit outdated compared to the exam content. But the good news is that, recently this month, Stephane has published a massive content update that covers most of the new exam contents.Neal Davis siteDigitalCloud.trainingcheat sheets were very useful to summerize and review after finishing the course.TutorialsDojopractice exam and flash card had a maximum advantage at the last day and even the last minutes.Practice this the key for passing and getting the most out of this exam, so keep it in mind, passing the exam and being certified is important but being qualified is far much important, AWS is useful so make use of it....

Unlike most people who take cloud certifications because they need it on job, I took this certification to break into a cloud career. I hold a MS in Software Engineering form an American University. I have worked as a JAVA developer for few years and then more in a PM role for the last 3 years. However, I wanted to come back to a technical role about which I am more passionate. I did review quite a few technologies to enter into and found that Cloud was probably the best. Cloud engineering is the latest, most in demand and is slated to grow for the next few years. Cloud engineering is also the most transformative of all the technologies out there. You can pretty much do any IT job on cloud. This in itself is marvellous enough.So, basically, I began my journey as a cloud novice. I do not have any practical experience in cloud engineering. So my first thought on getting in to this field was to get certified. I did some quick analysis on what certifications to start off with. AWS Cloud Architect Associate was the obvious choice as that would show potential employers about deep skill set baseline. Also, I chose AWS because as it is the leader in the cloud space and far ahead of its peers - Microsoft Azure and Google Cloud Platform.So to begin with, I read up on the net about various preparation material. Few popped up such as Acloud guru, Udemy, Linux Academy etc. I began with Acloud.guru. I studied for about a month and completed the entire lecture series. Then I looked for few practice question papers and found few on Udemy. I purchased Jon Bonso's practice papers and Whizlabs practice question papers. I took one Whiz labs practice test and failed miserably. Upon further analysis, I realized that Acloud.guru's materials was outdated. They did not have the latest material , but the practice exam had a lot of things that were not covered in Acloud.guru. So I decided to move away from Acloud.guru and decided to check other sites. Acloud.Guru did give some important info, but unfortunately as of April 2020, their material was outdated. They may have updated later on, but I am unable to verify that. After some analysis(based on many reviews and articles), it became clear that Stephane Maarek's Udemy course for Solution Architect- Associate was the best. Stephane has a very good and easy way of teaching. All his materials are absolutely updated and good for both the 2 versions(One retiring and one new version) of the architect exams. It took me a good 60 days or two months to complete the material studying about 2- 3 hours a day. Once I was done with the lectures, I just used the course slides to review. There are 660 review slides. I would revise about 220 slides each day and finish the entire material in 3 days. Once I had reviewed the slides about 3 times, I decided to take the practice exams. I first completed the Whiz labs question sets on Udemy and on all the 6 tests , I consistently scored between 81% - 83%. After the exams, I reviewed all the wrong answers in those practice exams in thorough detail. In between when I had completed the 3rd practice test, I booked for the actual exam. I had planned to complete Jon Bonso's pactice tests, but unfortunately, I ran out of time.Instead of cramming for the exam and taking Jon's practice tests , I decided that it is probably better to not stress out and be more relaxed during the last two days to exam. I had read some great reviews about Jon Bonso's exams, but just ran out of time.The day before the exam, I made sure to skim the slides once more. I paid particular emphasis on VPC, Security/Encryption, EBS, Database. These topics are really important for the exam.On the previous day of the actual exam which was an online proctored exam, I had to prepare my room according to AWS guidelines.About the actual test though, I don't have some great opinion. If possible, I recommend you take the exam in person at a test center. The online proctored exam has some stringent guidelines. You cannot make any lip movements(even if your lips are dry) , all the time your face has to be visible in the camera( if you move out of camera view, the exam can be terminated). It is very difficult to sit in front of the web cam for 1 hour(I took 1 hr to complete the exam. The actual duration is 2 hr 20 min) stiffly and also working on the exam.Inspite of all this, I passed my exam with 81% marks. The actual test was very similar to the Whizlabs practice exam papers on Udemy. So I did not find the actual test any different. My score on the Whizlab exams and the actual exams was similar. I highly recommend Whizlabs practice exams on Udemy. My score would have been better, if I had attempted Jon Bonso's papers. I will be glad to share any more details on the exam.

For those of you that still haven’t taken the Free Oracle Training and the certification exams, you still have time. You can take OCI certifications in any order but it is recommended to have the fundamentals ironed out. This time I took the Architect Associate Exam and managed to pass with moderate preparation. I took the OCI Foundations Exam, couple of weeks back and you can read about it in my previous blog. Remember certifications do not land you a job, but can help you get one and it’s a good validation of your skills. Read my earlier blog on why you should get certified.Now coming back to the OCI Architect Associate Exam. First of all, you should read Mukesh Sharma’s blog that covers all the topics that you might be asked in the real exam. It has a very good summary and excellent preparation notes of all the topics covered in the Oracle videos. This blog covers tips on some questions that you might see in your exam. Please note that this is based on my memory and you might see different topics in your exam. The exam is 105minutes long and it has 66 questions. The official oracle university course is 9hours 40mins long and I must confess that I watched it at 1.5X speed.So, in a random order, here are the tips on few items that I had in my exam:1. First of all, it is a must that you go through the original Oracle videos by Rohit Rahi. You do not need any other video content. Oracle University official videos are more than enough.2. If you haven’t created your OCI account, please do so. Oracle will give you $300 and a free one-month trial. Use it at your own discretion and remember to tear down the environment once you have practiced enough. I got a couple of items on debugging what could be wrong when the instance is not getting traffic from the internet. Know that Instance cannot communicate with another instance in same subnet until you permit them to. So, it is important to familiarize yourself with IGW, Route Tables, Security List, NSG to name a few. I didn’t get any question on port except for one which talked about port 22 for SSH.3. Remember to at least do one round of provisioning a running environment. I believe the videos could be improved in how other can create their own environment by providing custom scripts and walking through them. I’ve seen people struggle between using OS if they have to SSH into the instance as the setup might differ from Windows vs Mac.4. Most of the questions I got were with 2 correct choices. So, you really have to understand the OCI services in good way.5. I got a confusing question on if peering is allowed between two VCN’s and they had CIDR block listed. Understand that for peering to be allowed, there should not be any overlapping CIDR blocks.6. Know the difference between Internet and VCN Resolver and Custom Resolver.7. Important to understand how compartments work. I do not remember seeing anything on policy implication when moving compartments. That topic can be a little confusing when you haven’t had any hands-on practice.8. Another important topic is Connectivity between On Prem and OCI. Also, understand difference between VPN connect and FAST connect and what to use when. It is important to pay close attention to the demo that Rohit Rahi does in the videos.9. Understand File Storage specially how mounting works. Remember that Mount target has an IP address and DNS name that you use in your mount command. Also, placing NFS client and Mount Target in same subnet can result in IP conflicts as users are not shown which private IP are used for mount target. So, place FSS mount target in its own subnet where it can consume IP as needed. Finally, export path is unique path specified when the file system associated with mount target. /example & /example/path not allowed10. VNIC’s is another critical topic to understand and remember. Know that each VNICs has one primary private IP can have additional private IPs called Secondary Private IP up to 31 Secondary Private IPs. Ephemeral IP can be assigned to Primary Private IP only. Hence only 1 per VNIC vs max 32 for reserved IP.11. It is important to remember what type of database to use when and for what option the db storage and/or CPU can be changed.12. Understand how OCI Data Gaurd is used. Oracle Data Guard is supported on both virtual machine and bare metal DB systems. It is limited to one standby database per primary database on OCI. If the customer has a database license for Active Data Guard or deploys the Oracle Enterprise Extreme Performance package, they can use the standby database in a Data Guard setup for queries, reporting, running tests, or backing up the database from the standby. Understand when to do a planned switchover vs a failover.13. No exam is complete without question on backups. Remember that by default, automatic backups are returned to Oracle owned object storage. Customers will not be able to view the object storage backups. There are the preset retention periods for automatic backups, 7 days, 15 days, 30 days, 45 days, and 60 days. The default policy cannot be changed at this time. You can also do a standalone backup. On demand standalone full backups are stored till the point you decide to delete it from the OCI console. You can restore a database to the latest backup. Or you can restore the database to the timestamp.14. All cloud providers judge your knowledge on Load Balances. Remember that Load balancer (LB) stops sending traffic to bad instance. Understand the type LB policies – Round Robin, IPHash, Least Connection. Also, remember to study the health status, drain, offline and backup state.15. What happens to boot volume when the instance is terminated – you have the option to preserve it. Also, study on boot volume backup and know that it doesn’t require downtime. Also, there is cost associated with amount of object store used to store backup.16. Image Import/Export questions can be tricky. Image export import enable you to share custom image across tenancies and region. Image export import uses OCI Object Storage. Mode of Import Export to spin your own instanceEmulation Mode - VM IO device CPU & Memory are implemented as software, Emulated VM support almost any X86 OS. These VM are slowPara Virtualized - VM include a driver specially designed to enable virtualizationNative Mode (SR-IOV Single Route IO Virtualization)- same as Hardware Virtualized Machine (HVM) offers maximum performance with modern OS17. It goes without saying that Object Storage is an important topic for the exam. Understand how Multipart Upload works. There is a 10TB limit, Individual part can be as big as 50 GB or as small as 10MB. Initiate and upload by calling api CreateMultiPartUpload. Make an upload part request for each object part upload. You can restart failed upload part. No need to restart all upload.18. Cross region copy is another important topic. Copy objects to other buckets in the same region and to buckets in other regions. For this to happen, you must authorize the service to manage objects on your behalf (Separate policy for each region). In the policy, you must specify a target bucket. Unfortunately, bulk copying is not supported right now. Also, objects cannot be copied from archive storage.19. Understand the difference between Autonomous Data Warehouse and Autonomous Transaction Processing. The topic can get confusing so, it is important to know the difference and what to use when.20. Finally, understand where all cloning can take place, starting from Boot Volume, Block Volume, cloning an instance, Cloning a Volume group, Autonomous data base. This is a very important topic.That’s it folks. This is all that I can remember from what I got in my exam. Please note that I don’t remember the exact question and I’ve listed the topics which are important for you to remember for the exam....
