How to Pass Azure Fundamentals AZ-900 and the new changes coming May 28, 2020

Azure Fundamentals
Azure Fundamentals Preparation Guide

As the name suggests, this is most basic exam in the list of Azure Cloud exams. If you have been in IT industry for some time and know the fundamentals of cloud, you are golden. Additionally, if you hold a cloud certification for other cloud providers, it will be easy for you to get this one. However, if you are new to all this, do not worry. Below I’ve described my one day preparation for this certification.

Before I start, our company sponsored the one day training and the trainer was from Microsoft. Let’s get started.

First and foremost, check out this link on the Microsoft site that has the outline of the exam. As per Microsoft, the content of AZ-900 exam will be updated on May 28, 2020. The new format is much more streamlined and categorized. The topics that are covered in the exams are:

NewOld
Understand cloud concepts (15-20%)Describe cloud concepts (20-25%)
Understand core Azure services (30-35%)Describe core Azure services (15-20%)
Understand security, privacy, compliance, and trust (25-30%)Describe Identity, Governance, Privacy and Compliance Features (20-25%)
Understand Azure pricing and support (20-25%)Describe Azure Pricing and Support (10-15%) 
Describe General Security and Network Security Features (10-15%)
Describe Core Solutions and Management Tools on Azure (10-15%)

Now in my opinion, regardless of the new or old format, the preparation materials should not change that much. Let us break down each section further to help you understand the changes.

Cloud Concepts

The basic cloud concepts that you will be tested on include:

  1. Benefits and considerations of using cloud services,
  2. Differences between Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS),
  3. Differences between public, private and hybrid cloud models

Going forward, Microsoft has added two important topics under these sections – one is more emphasis on the shared responsibility model and other to identify a service type based on a use case. This can potentially mean the user can expect a few scenario based questions based on these two changes.

Core Azure services

The concepts that you will be tested on include:

  1. Azure architectural components 
  2. Core workload products available in Azure 
  3. Solutions available on Azure
  4. Azure management tools 

The #3, and #4 point above have been combined as one and moved to their own section in the new model. Refer to the change table above (Describe Core Solutions and Management Tools on Azure) . However, in my opinion nothing new is added from materials standpoint.

Identity, Governance, Privacy and Compliance Features

The concepts that you will be tested on include:

  1. Core Azure identity services
  2. Azure governance features
  3. Privacy and compliance resources

Azure Pricing and Support 

The concepts that you will be tested on include:

  1. Methods for planning and management of costs 
  2. Azure Service Level Agreements (SLAs) and service lifecycles 

Core Solutions and Management Tools on Azure (New Section)

The concepts that you will be tested on include:

  1. Core solutions available on Azure 
  2. Azure management tools

General Security and Network Security Features (New Section)

The concepts that you will be tested on include:

  1. Azure security features
  2. Azure network security

Important Pointers for the AZ-900 Exam

The cost of the current AZ-900 exam is $99. The exam is one hour and the number of questions usually vary between 41-45. There are a number of Yes/No questions and of course multiple choice questions. There is a set of drag and drop type questions which you have match the Azure services to what they offer. I took practice exams at reviewNprep.com for extra practice and they do help. If you are well prepared, you will have plenty of time to spare and re-look at the answers. Below are some of the important pointers that one needs to be aware of:

  1. Economies of scale: This is the ability to reduce costs and gain efficiency when operating at a larger scale in comparison to operating at a smaller scale.
  2. Expenditure Model
    • Capital Expenditure (CapEx): This is the spending of money on physical infrastructure up front, and then deducting that expense from your tax bill over time.
    • Operational Expenditure (OpEx): This is spending money on services or products now and being billed for them now. There is no up-front cost, you pay for a service or product as you use it and you can deduct this expense from your tax bill in the same year.
  3. Shared responsibility model ensures cloud workloads are run securely and in a well-managed way.
    • IaaS: With IaaS, you rent IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems from a cloud provider on a pay-as-you-go basis.
    • PaaS: The goal of PaaS is to help create an application as quickly as possible without having to worry about managing the underlying infrastructure.
    • SaaS: This is software that is centrally hosted and managed for the end customer.
  4. Azure compute: This is an on-demand computing service for running cloud-based applications. It provides computing resources such as disks, processors, memory, networking and operating systems.
    • Azure Virtual machines (VMs): are software emulations of physical computers. They include a virtual processor, memory, storage, and networking resources.
    • Virtual machine scale sets: Azure compute resource that you can use to deploy and manage a set of identical VMs.
    • App services: You can quickly build, deploy, and scale enterprise-grade web, mobile, and API apps running on any platform.
    • Azure Functions: are ideal when you’re concerned only about the code running your service and not the underlying platform or infrastructure.
    • Azure Container Instances offers the fastest and simplest way to run a container in Azure without having to manage any virtual machines or adopt any additional services.
    • Azure Kubernetes Service (AKS) is a complete orchestration service for containers with distributed architectures and large volumes of containers.
  5. Azure Networking
    • Azure Virtual Network enables many types of Azure resources such as Azure VMs to securely communicate with each other, the internet, and on-premises networks.

    • The Azure Database Migration Service is a fully managed service designed to enable seamless migrations from multiple database sources to Azure data platforms with minimal downtime (online migrations).
  7. Azure Marketplace is a service on Azure that helps connect end users with Microsoft partners, independent software vendors (ISVs), and start-ups that are offering their solutions and services, which are optimized to run on Azure.
  8. IoT Central is a fully managed global IoT software as a service (SaaS) solution that makes it easy to connect, monitor, and manage your IoT assets at scale.
  9. Azure IoT Hub is a managed service hosted in the cloud that acts as a central message hub for bi-directional communication between your IoT application and the devices it manages.
  10. Azure Big Data and Analytics:
    • Azure SQL Data Warehouse is a cloud-based Enterprise Data Warehouse (EDW) that leverages MPP to run complex queries quickly across petabytes of data.
    • Azure HDInsight is a fully managed, open-source analytics service for enterprises.
    • Azure Data Lake Analytics is an on-demand analytics job service that simplifies big data.

If you can remember all of the above points, you are good to appear and hopefully pass the AZ-900 exam in the first attempt. Remember to have a good night rest before the exam and don’t overthink about this exam. Good Luck!
