Deliver software with DevOps

Optional foundation

Check your starting knowledge

Use AZ-900 to review the basics. You do not need to take this foundation exam to follow our route. If you already know the material, move on.

Certification requirement · verify eligibility

Account for the qualifying credential

Microsoft lists Azure Administrator Associate or Azure Developer Associate as alternative prerequisite certifications for DevOps Engineer Expert. This guide shows the administrator route; verify current eligibility on the certification page.

Core learning · AZ-400

Learn the role, one area at a time

Work through the official guide and its learning resources. Use these three study blocks to organize your notes; the official skills outline remains your complete coverage checklist.

1. 1.Collaboration, source control and development processes
2. 2.Build, test and release pipelines
3. 3.Supply-chain security, instrumentation and feedback

Hands-on consolidation

Put it into practice

Build a pipeline for a tiny sample application with tests, a review gate, secrets handling and a rollback plan.

Use a dedicated lab and synthetic data, never an employer's production environment. Check licensing and costs before provisioning; budget alerts do not stop spending. Remove resources when finished.

Review & exam planning

Find gaps with our AZ-400 test

Try the test, explain each missed answer and return to the corresponding learning topic. Repeat the practical task where needed. A practice score is feedback, not proof of certification readiness.

Before booking, check the official page for current exam availability, any retirement or beta notice, and the credential's full requirements. This guide does not track completion or award a certificate.
