Major Exam Topics

To get the required score and obtain the expert-level certification, you need to master the certain topics, each having the particular percentage of the whole content. The domains include the following:

• Implement Continuous Integration (20-25%).
• Facilitate Communication and Collaboration (10-15%);
• Develop a Site Reliability Engineering Strategy (5-10%);
• Design a Security and Compliance Plan (10-15%);
• Implement a Release Management and Continuous Delivery Strategy (10-15%);
• Manage Source Control (10-15%);
• Develop an Instrumentation Strategy (5-10%);

It is important to know all the subtopics and vital details related to these areas so that you will be able to master them. Therefore, let’s look at this information.

Domain 1: This objective includes three main subtopics that are covering the least amount of the whole exam content. Thus, you should know how to design an actionable alerting strategy, a failure prediction strategy, and implement a health check. This means that it is important to know how to identify metrics and recommend them on which to base alerts, analyze combinations of metrics, as well as design the mechanisms of communication to notify the users of degraded systems. A potential candidate has to understand the behavior of a system, know how to analyze it, measure baseline metrics, and know which tools to use to prevent the system from failure. Analyzing system dependencies is also an important task to deal with.

Domain 2: This area proves that you are capable of designing authentication and authorization strategies, sensitive information management strategies, security and compliance, as well as governance enforcement mechanisms. These four subjects include the skills in organizing teams with the use of Azure AD groups, evaluating vault solutions, as well as assessing and reporting risks. Your knowledge also requires the ability to implement container scanning and Azure policies.

Domain 3: This topic covers the generation of DevOps process documentation, automation of communication with team members, and your ability to communicate with the business stakeholders about the deployment and release information. This means that you have to know how to integrate GitHub as repository with Azure Boards and notify the stakeholders about key metrics, alerts, and severity using Teams, Slack, SMS, or Email. One’s skills in documenting artifacts and external dependencies are also important.

Domain 4: This subject includes the students’ ability to develop logging and telemetry, implement them, and integrate monitoring and logging solutions. Thus, you need to know all about the integration of crash analytics such as Crashlytics or App Center Crashes and creation of the feedback loop from platform monitoring tools, including Event Grid, Azure Platform Logs, and Azure Diagnostics VM extensions. Your knowledge base should include your understanding of key metrics, such as Teams/Slack, network, webhooks, disk, SMS and Email, memory, and CPU, as well as your ability to define them, measure, and implement alerts on them.

Domain 5: The main subtopics of this area include the development of a modern source control strategy, implementation of branching strategies for the source code, integration of source control with tools, and configuration of repositories.

Domain 6: This section covers the learners’ skills in implementing an orchestration automation solution, planning a deployment environment strategy, and developing deployment scripts and templates. Load balancer, App Center, ARM, Azure Stack, Terraform, PowerShell DSC, GitHub Actions, IoT, CLI, multiregion, Azure Pipelines, DR, sovereign Cloud, Jenkins, Azure IoT Edge, CircleCI, mobile, and CDN are the technologies that you should know all about.

Domain 7: The last topic has the highest percentage of the exam content, which means that you will face with more questions from this section than others. It covers a wide area of subjects that include the maintenance of a build strategy, its implementation, as well as design of a package management strategy, build automation, and a process for standardizing builds across the organization.

How can you prepare for the Microsoft AZ-400 exam?

The Microsoft Learning Platform offers two preparation options for the candidates taking the Microsoft AZ-400 exam. These are free online training resources and paid training courses. Let’s look at these two options in detail.

• Free Resources

  This preparation path offers the students the platform to gain the skills and knowledge required to pass the certification exam. There are six different learning paths available for this test on the Microsoft Learning Platform. These include:

  • AZ-400: Developing an Instrumentation Strategy
  • AZ-400: Developing a Site Reliability Strategy
  • AZ-400: Developing a Security & Compliance Plan
  • AZ-400: Handling Source Control
  • AZ-400: Facilitating Communication & Collaboration
  • AZ-400: Defining & Implementing Continuous Integration
  
  

  Each of these learning paths has different modules (ranging from 6 to 12). With these resources, you will develop the expertise that you need to ace your certification exam at your first attempt.

• Paid Training

  This is an instructor-led training delivered under the guidance of the Microsoft authorized trainers. The official course for Microsoft AZ-400 is Designing & Implementing Microsoft DevOps Solutions. It offers the participants the skills and knowledge for designing and implementing DevOps practices and processes. The candidates will learn the process involved in planning for DevOps; using source control; consolidating artifacts; scaling Git for enterprises; implementing a container build strategy; implementing continuous integration; designing a release strategy; optimizing feedback mechanisms; implementing deployment patterns; setting up the release management workflow, among others. The participants of this instructor-led training will develop the theoretical and hands-on skills required to achieve success in the certification exam.

Conclusion

In summary, Microsoft AZ-400 is not one of the easy exams, as it’s of the expert-level and earns you the Microsoft Certified: DevOps Engineer Expert certification. However, keep in mind that for admission to the AZ-400 exam you must already be an expert either in Azure Administration or development as well as have a clear understanding and knowledge of Azure and cloud computing. Thus, you need to be serious about your prep process and opt for the most effective options. Start with books covered in this description, attend the official training courses, take practice tests, and pass this exam on the first try.
