Microsoft DevOps Engineer Expert: the honest guide
Everything Microsoft Azure publishes about AZ-400, in one place: what the exam asks, how the domains are weighted, and what it takes to be ready.
This guide page is built from the registry, not written yet.
Everything below comes from Azure DevOps Engineer’s published exam data, and every figure links to the vendor page it came from. The researched version, with study plans and the parts nobody publishes, is still being written. This page is not submitted to search engines until it is.

Frequently asked questions
What dominates AZ-400?
Pipelines, overwhelmingly: the build and release domain is over half the exam. YAML pipeline structure, environments and approvals, deployment strategies, agents, and artifact and package flows through Azure Artifacts and GitHub.
Azure DevOps or GitHub for the exam?
Both. Microsoft examines the concepts across Azure Pipelines and GitHub Actions, branch policies in both products, and GitHub Advanced Security alongside Defender for Cloud. Prep that ignores either product leaves marks behind.
Note on domain weightings
Microsoft publishes weightings as ranges. The figures here use midpoints of the official ranges from the current AZ-400 study guide.
