Our az 400 practice test is a multiple-choice and multiple-response mock covering all five exam domains at Microsoft's published weighting, scored against Microsoft's own 700-out-of-1000 passing standard. It does not include the interactive, hands-on task types Microsoft says the real exam may contain, so pair it with real Azure DevOps and GitHub Actions practice.
The az 400 practice test on this site is built directly from the domain weights on the exam objectives page: design and implement processes and communications, source control strategy, build and release pipelines, security and compliance, and instrumentation. Here is exactly what it contains, what it cannot contain, and how to use it inside a study plan.
What the AZ 400 mock test contains
Every question is multiple-choice or multiple-response, written to the same domains and weighting Microsoft publishes for the real exam. Build and release pipelines gets by far the largest share of questions, matching its outsized weight on the real exam, while instrumentation gets the smallest share. Each question comes with an explanation after you answer, naming the strongest wrong option and why it is close but incomplete, not just which letter was correct.
Scoring uses Microsoft's own scale: a result out of 1000, with 700 as the passing mark, the same standard published on the exam format page. That means your practice test result is directly comparable to what a pass or fail would look like on the real exam scale, not an arbitrary percentage invented for this site.
How the AZ 400 practice exam report works
After you finish, the report breaks your result down by domain, not just an overall score. Because build and release pipelines carries more than half the total exam weight, a weak score there matters far more to your real-exam readiness than a weak score in instrumentation, even if both show the same raw percentage. Use the domain breakdown to decide where to spend your remaining study time, rather than treating every wrong answer as equally important.
What our AZ-400 practice test does not reproduce
Microsoft states the real exam "may have interactive components" — tasks performed against a live or simulated environment rather than answered as multiple choice. Our mock does not include these, because a written question format cannot simulate configuring a real pipeline or repository. This is the single biggest gap between any practice test, including ours, and the real AZ-400 exam. A strong practice test score tells you that your conceptual and scenario-reasoning knowledge is solid; it does not confirm you can execute a task hands-on under exam conditions.
Using a mock test across a study plan
A single practice test attempt near the end of preparation tells you less than several attempts spaced across your study plan. Take an early attempt to find your weakest domains before you plan detailed study time, then a mid-plan attempt to check whether that studying moved your score, and a final timed attempt close to your exam date to confirm pacing and pinpoint any remaining gaps. Because pipelines is the majority of the exam, track that domain's score across attempts specifically, not just your overall result.
Pair every mock attempt with hands-on work: if a question about YAML pipeline triggers or branch protection rules trips you up, go configure that exact thing in a real Azure DevOps or GitHub project rather than only rereading the explanation.
Before you book the real exam
Confirm your prerequisites match Microsoft's recommended background, review exam format and scoring so the 700-point standard is familiar, and check cost and booking once your practice test scores are consistently where you want them. Our sample questions page shows the exact style and difficulty of the questions inside the full mock, and the exam-day guide covers what to expect on the day itself.
