Azure DevOps Engineer Expert (AZ-400) is a Microsoft certification. These facts come from the current exam guide and are the numbers to plan around.
| Domain | Weight | What to focus on |
|---|---|---|
| Design and implement build and release pipelines | 43% | Azure Pipelines: YAML and classic pipelines, Build agents: Microsoft-hosted and self-hosted, Artifacts: Azure Artifacts, NuGet, npm, Maven |
| Design and implement source control | 18% | Git branching strategies: trunk-based, feature branches, GitFlow, Pull request workflows and branch policies, Git hooks and repository health |
| Configure processes and communications | 13% | Azure Boards work items and backlogs, Agile planning and sprint management, GitHub integration with Azure DevOps |
| Develop a security and compliance plan |
| 13% |
| Static application security testing (SAST), Software Composition Analysis (SCA) and dependency scanning, Container image scanning |
| Implement an instrumentation strategy | 13% | Azure Monitor and Application Insights, Distributed tracing and correlation IDs, Log Analytics workspaces and KQL queries |

They cover all 5 domains of the AZ-400 exam: Design and implement build and release pipelines (43%), Design and implement source control (18%), Configure processes and communications (13%), Develop a security and compliance plan (13%), Implement an instrumentation strategy (13%). Each section is weighted in the same proportion as the real exam, so nothing high-value is buried.
The AZ-400 exam has approximately 60 questions in 150 minutes, with a passing score of 700. Use the practice questions to confirm you are consistently above that line before booking the real exam.
Study in short, spaced sessions: a card you have not seen for two days is worth more than a card you reread immediately. Filter by Design and implement build and release pipelines first, then mix domains so you practise identifying the topic before recalling the definition.
They are the recall half of preparation. Pair the cards with practice questions and at least one timed practice exam — candidates who only review cards usually recognise terms but miss scenario questions.
