AZ-400 DevOps Engineer Expert: 500 Practice Questions

Have you worked through the AZ-400 learning paths and still don't know whether you are ready to book the exam? These practice tests answer that question and show where your gaps are.

The course contains five practice tests with 100 questions each, 500 in total, written against the AZ-400 study guide with skills measured as of July 27, 2026. Every test follows the official weighting: build and release pipelines take just over half, and the rest covers processes, source control, security and instrumentation.

AZ-400 has no retired predecessor, but its products have changed a lot. Azure AD is now Microsoft Entra ID, GitHub Advanced Security is sold as GitHub Secret Protection and GitHub Code Security, Managed DevOps Pools is the recommended way to scale self-hosted agents, workload identity federation replaces stored secrets, URL ping tests have given way to standard availability tests, and Azure Automation State Configuration is on its way out in favour of Azure Machine Configuration. Practice material written a few years ago still teaches the old answers. These questions follow the current Microsoft Learn and GitHub Docs pages.

The five tests get harder in how the questions are asked, not in how obscure the facts are:

• Test 1, Groundwork: direct questions, one concept each.

• Test 2, In Practice: short scenarios that separate features people often mix up.

• Test 3, Trade-offs: two answers look right and one requirement decides.

• Test 4, Under the Hood: YAML keywords, task inputs, CLI commands and settings.

• Test 5, Exam Day: long multi-requirement scenarios and troubleshooting in one timed sitting.

Every answer option has its own feedback that says why it is right or wrong, and what a wrong option actually does. Each question also has an overall explanation with a link to the official documentation, so you can check the source yourself.

After each attempt Udemy shows your score per skill area, so you can revise where it matters. The pass mark is 80% for tests 1 to 4 and 85% for test 5, deliberately higher than the real exam.

What this course is not: it is not a video course and not a copy of the real exam. AZ-400 exam questions are confidential, and nothing here claims to reproduce them. Use these tests alongside the free Microsoft Learn material and hands-on practice to measure and sharpen what you know.
