Microsoft Certified: DevOps Engineer Expert credential artwork

Microsoft Certified: DevOps Engineer Expert (AZ-400)

Validates knowledge of designing DevOps solutions, including source control, build and release pipelines, security and compliance, and instrumentation.

Summary

DevOps Engineer Expert is Microsoft's certification for building and running delivery pipelines with GitHub and Azure DevOps, tested by the AZ-400 exam. It covers work tracking, source control, build and release pipelines, security in automation and monitoring, with pipelines about half the exam.

Good fit if

  • You build and maintain CI/CD pipelines in GitHub Actions or Azure Pipelines
  • You hold AZ-104 or an Azure Developer Associate certification
  • Postings you target list AZ-400 or DevOps Engineer Expert

Look elsewhere if

  • You have not worked hands-on in Azure yet: AZ-104
  • Your work centers on Terraform across several clouds: Terraform Associate
  • You design overall Azure solutions, not pipelines: AZ-305

FAQ

Do I need AZ-104 before I can take AZ-400?

No. You can take AZ-400 first. Microsoft awards DevOps Engineer Expert once you have passed AZ-400 and hold Azure Administrator Associate or Azure Developer Associate.

Does Azure Developer Associate still count now that AZ-204 has retired?

Microsoft still lists Azure Developer Associate as a qualifying certification. New candidates can no longer take AZ-204, so they qualify with AZ-104.

How much does the AZ-400 exam cost?

$165 in the US. If you need AZ-104 as well, that is another $165.

Does AZ-400 include a lab?

It can. Microsoft does not say in advance which exams include labs. The overview screens at the start of your exam tell you.
