AZ-400: Microsoft Azure DevOps Solutions Certification Exam 4

The AZ-400 Microsoft Azure DevOps Solutions certification exam tests and validates a candidates expertise as a DevOps Professional around the use of Microsoft Azure technologies for designing and implementing DevOps practices. This exam is a part of the required exams needed to earn the larger Microsoft Certified: Azure DevOps Engineer Expert certification.

AZ-400 Exam Target Audience

The AZ-400 Microsoft Azure DevOps Solutions certification exam is geared towards DevOps Professionals (or Site Reliability Engineers / SREs) who combine people, process, and tools to continuously deliver value to meet users needs and business objectives. These candidates streamline delivery by optimizing practices, improve communication and collaboration, and create automation. They design and implement strategies for app code and infrastructure that allows for continuous integration, continuous testing, continuous delivery, and continuous monitoring and feedback.

Exam candidates are expected to be proficient with Agile practices, and must be familiar with both Azure Administration and Azure Development, and should be experts in one of these areas. They must be able to design and implement DevOps practices for version control, compliance, infrastructure as code (IaC), configuration management, build, release, and testing by using Microsoft Azure technologies.

AZ-400 Exam Study Resources

The first resource that is really great at learning and referencing how to use Azure DevOps is the official documentation. However, if you are new to Azure DevOps that can be a bit difficult to use without a more guided approach. Many of the Microsoft certification exams do have official Exam Reference books published from Microsoft Press, however, the AZ-400 DevOps Engineer is not one of them.

Here are some FREE learning and study resources that you’ll find useful when preparing for this exam:

  • Azure DevOps Labs – This is a great collection of Azure DevOps lab guides that you can follow using your own subscription and account.
  • AZ-400 Microsoft Official Courseware Hands-on Labs – These are FREE hands-on labs maintained by Microsoft. These are the Official Microsoft Curriculum labs used in paid Microsoft training courses for this certification, and you can access these labs completely free as they are hosted on GitHub. 
  • Microsoft Learn DevOps Modules – Microsoft Learn has a few modules around the topics of Azure DevOps that you can use to study.
  • Continuous Delivery in Azure DevOps Microsoft Cloud Workshop – This MCW is a great learning resource that can be used to learn more about Azure DevOps. It includes a Whiteboard design session that you can use to run through designing a DevOps solution, and it includes a Hands-on Lab that you can use to get in there and work with Azure DevOps for yourself.
