  • OCI 2019 Architect Associate
    May 11, 2020, 02:05 AM

    So, I cleared the exam on 8 may 2020. Few things that helped me a lot while preparing for the exams are as follows :

    1. I watched the training videos with full concentration and being a beginner in the cloud I watched it twice as if I had missed                 something in the first attempt.

    2. I thoroughly studied Oracle Cloud Documentation (only those topics that were mentioned in the syllabus).

    3. I took the practice test of Oracle (available in the course itself), once I was confident that I was packed with all the stuff and ready to  appear for the exam.

    Note:

    1. Don't skip the video and listen to the instructor very carefully because some really helpful points that he had told were directly came in the exam.

    2. Doing the hands-on is must for the better understanding and from the exam point of view. Try to explore as much as you can from     your free 30 days trial.

    3. There will be some conceptual questions in the exam which you can only answer if you have done hands-on properly.

    4. If possible make the notes of the services.

    Thanks and all the best,

    Tips on how to pass OCI Architect Associate Exam
    May 03, 2020, 03:05 PM
    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 allowed
    10. 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 instance
    • Emulation Mode - VM IO device CPU & Memory are implemented as software, Emulated VM support almost any X86 OS. These VM are slow
    • Para Virtualized - VM include a driver specially designed to enable virtualization
    • Native Mode (SR-IOV Single Route IO Virtualization)- same as Hardware Virtualized Machine (HVM) offers maximum performance with modern OS
    17. 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.

    How to prepare for OCI 2019 Architect Associate exam
    April 26, 2020, 07:04 AM

    How to prepare for OCI 2019 Architect Associate exam

    I recently prepared for an passed the Oracle Cloud Infrastructure 1Z0-1072-OCI-Architect-Associate-2019 exam. The format and the content for the exam is available on Oracle’s education site –

    Become an OCI architect Associate

    I would absolutely recommend a refresh of the OCI fundamentals before jumping into the OCI architect course.

    I went through the course once at 2x speed and captured most of the information in a word document. The exam is supposedly not as difficult as any other AWS or GCP associate level exams. I am listing the main topics of the preparation course and some of the key elements you should understand and remember before you take the #FREE exam offered by Oracle.

    All resources shared during the course are available at this training site location - OCI Architect Associate Resources

    Getting Started with OCI

    To better understand the OCI interface as well as all the services please review the Infrastructure as a service documentation available here at OCI IAAS Documentation site and services availability across regions across the world.

    Lets now focus on individual services and some of the focus areas to remember

    1.       Identify and Access Management

    ·         IAM – There are mainly 4 verbs used in IAM to define a policy and they are inspect, read, use and manage.

    o   Inspect – provided the ability to list resources

    o   Read – Includes inspect and ability to get user specified metadata/actual resource

    o   Use – Includes read + ability to work with existing resources (the actions vary by resource type). This verb does not allow the ability to create or delete any type of resource.

    o   Manage – Includes all permissions for the resource

    ·         IAM-Policies

    o   The most common format of an IAM policy is listed below –

    Allow to in where

    The subject can be an IAM user, group, resource group etcetera

    Please pay special attention to managing users, groups, Dynamic groups and network resources. You must specially understand that if you want to provide a specific role to a compute instance, you need to attach a dynamic group to it so that it is identified as “principal” and it can make API calls against other services on OCI.

    ·         IAM-Compartment – Compartments are another way to manage your resources by relating them together and accessed by groups that are given permission.

    o   It must be understood that each resource can belong to one and only one compartment. However, resources can be shared across compartments.

    o   Resources can also be moved across compartments once they have been created.

    o   Compartments can have sub compartments that can go six level deep.

    §  COMP1 > COMP2 > COMP3 > COMP4 > COMP5 > COMP6

    §  These sub compartments inherit access permissions from compartments higher up the hierarchy

    o   When an IAM policy is being created, it must be specified which compartment to attach it to.

    ·         IAM Policy Inheritance and Attachment

    o   Understand how IAM policy inheritance work when resources are moved across compartments.

    ·         IAM-Tags

    o   Tagging is an additional method to identify/categorize your services inside your compartments.

    o   Free form and custom tags are allowed under OCI.

    2.       OCI Networking

    It should be emphasized that you must have understanding of creating public and private networks and how all private networks use CIDR ranges identified under RFC 1918. The major networking components of OCI networking is listed below -

    o   VIRTUAL CLOUD NETWORK (VCN) and Subnets

    §  Default route table

    §  Default Security list

    §  Default DHCP options

    o   VNIC

    o   PRIVATE IP

    o   PUBLIC IP

    o   IPV6

    o   DYNAMIC ROUTING GATEWAY (DRG) – Connect on-premises networking and use it to peer VCNs across regions with remote peering gateway. Please understand that DRG connections are always private when used either with Fastconnect for in premises or with RPC across regions to pair VCNs.

    o   INTERNET GATEWAY

    o   NETWORK ADDRESS TRANSLATION (NAT) GATEWAY

    o   SERVICE GATEWAY – These provide a way to connect resources in your VCN to other manager services like OCI object storage.

    o   LOCAL PEERING GATEWAY (LPG)

    o   REMOTE PEERING CONNECTION (RPC) – Understand the user dynamic routing gateway (DRG) with on premises versus using DRG with RPC in a multi-region configuration.

    o   ROUTE TABLES

    o   SECURITY RULES

    §  Difference between security lists and network security groups.

    o   DHCP OPTIONS

    o   FastConnect

    o   VPN Connect – Please do take a moment to understand how to establish cost effective and redundant connectivity with OCI using VPN connect and DRG. I found this example very interesting to read and understand.

    Overview of connectivity options on OCI

    3.       Load Balancing on OCI

    o   Concepts of load balancing on OCI

    §  Service discovery

    §  Health Check

    §  Algorithm

    o   Benefits of load balancing on OCI

    §  Fault tolerance and high availability

    §  Scale

    §  Naming Abstraction

    o   Concepts of a public load balancer

    §  Listener

    §  Backend server

    §  Load balancing policy

    §  Round Robin

    §  IP Hash (sticky connections)

    §  Least Connection

    §  Back end sets

    §  Health Checks – this is a test to confirm the availability of backend servers. Health check is activated for backends, backend sets and overall load balancer.

    o   Concept of private load balancer

    4.       Compute on OCI

    o   Bare Metal

    o   Virtual Machines

    o   Dedicated VM Hosts

    o   Creating Custom Images of Boot Volumes

    § Pre-built OCI Images

    § Custom Images

    § Bring your own image (BYOI)

    o   Images Import/Export

    § Emulation Mode

    § Para virtualized Mode

    § Native Mode

    o   Boot Volumes

    o   Cloning a boot volume – Please ensure that you check out the difference between boot volume backups and clones and how they are mutually exclusive to each other.

    o   Instance Configuration and pools – configure and manage a set of instances/images together.

    o   Autoscaling configurations

    o   Instance Metadata

    o   Instance Life Cycle – start/stop/reboot/terminate

     

    5.       Storage on OCI

    o   Object Storage

    § Using Object Lifecycle

    § Using Multipart uploads

    § Using pre-authenticated requests

    o   Archive Storage

    o   File Storage – Please read through the concepts of creating/managing files systems, managing mount targets, snapshots , using export options (to provide granular access to a file system mounted on same mount target and accessed by two different clients/instances) etc. I found this complete section extremely useful.

    o   Block volume storage

    § Volume Groups

    § Attaching a volume

    § Resizing of block volumes

    § Block Volume Backups

    § Cloning a block volume

    § Volume Groups

    o   Local NVMe Storage

    6.       Databases on OCI

    o   Exadata cloud

    o   Exadata DB Systems

    o   Bare Metal and VB DB Systems

    o   Autonomous Databases

    § Autonomous transaction processing

    v  Managing Users

    v  Backup and restore

    v  Where does tnsames.ora reside -It resides in oracle home\NETWORK]\ADMIN directory

    v  How to load data into Autonomous databases with SQL*loader & Data Pump

    §  Autonomous data warehouse

    v  Loading data on ADW using SQL*loader & data pump & OCI object storage

    Some additional resources that I think are extremely useful to review that were not covered in the course are listed below –

    §  Using Data Guard for database services

    §  Data Flow

    §  Data Safe

    §  Data Science

    §  Data Science

    §  Oracle Audit

    §  OCI DNS Service

    §  OCI Traffic Management

    §  OCI Vault

    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.
