700 AZ-400 practice exam questions across all five objective domains, written to the current study guide. 40 free, and no explanation repeats its answer.
700 practice questions for AZ-400, covering all five objective domains in the proportions Microsoft publishes. Forty are free, and every explanation teaches the distinction the question turned on instead of repeating the answer.AZ-400 is the exam behind the Microsoft Certified: DevOps Engineer Expert credential, and Microsoft expects you to arrive holding AZ-104 or AZ-204 already. It tests whether you can design a delivery process end to end: how code is branched and reviewed, how it is built and released, how identity and secrets are handled along the way, and how you find out what happened afterward. This bank holds 700 questions written against the current published study guide, and they are distributed across the five objective domains in the proportions Microsoft weights them, so the practice you get matches the paper you sit on.
The wrong preparation for AZ-400 is memorizing task inputs and YAML keys. Almost every question here gives you a situation with a constraint in it and asks which arrangement fits: which agent type, where a control belongs, which deployment pattern the risk calls for, whether a thing should be automated or approved.
Two options are usually both workable and one of them is right for the constraint that was stated. That is what the real paper does, and it is why candidates who know the tools well still fail it.
Every explanation explains the decision rather than repeating the winning option, and it names the boundary where the other choice would have been correct. That is a substantive difference, not a stylistic one: an explanation that says "use a deployment stack because a deployment stack is right here" leaves you no readier for the next question than you were before it. Each one also cites the document it was written from, so you can go and read the source rather than take our word for it.
This is where most AZ-400 material has quietly gone wrong. Public projects in Azure DevOps are retired, and the unlimited hosted pipeline minutes that came with them go too. The Log Analytics agent retired in 2024, and its ingestion is being shut down, so an estate still running it is on borrowed time. Complete deployment mode is being deprecated in favor of deployment stacks, which reverses the answer most courses still teach for removing resources. GitHub Advanced Security for Azure DevOps is now two products bought separately. Every one of those is tested here, because every one of them is a question a candidate revising from last year's course gets wrong.
Exam Coach AI sits next to the question while you work. Ask it what something is, when you would choose one thing over another, or why a pattern exists, and it answers in plain terms without touching your exam. It will not tell you which option to pick or narrow them for you, because the decision is the thing being practiced. It is there for the moment you recognize the term and cannot remember what separates it from the one beside it.
Microsoft names both as the expected starting point, and the overlap is real rather than marketing. AZ-104 gives you the identity, networking and monitoring foundations that AZ-400 assumes and then tests as decisions instead of configuration. AZ-204 gives you the application side, and AZ-400 asks how that application reaches production safely. If either is still ahead of you, sit it first; if you have just passed one, this is the natural next paper.
Each sitting draws 60 questions from the pool of 700 and marks them as a plain percentage, with 70% needed to pass. That is our own mark, not a vendor scale. Questions are drawn across all five domains in their published proportions, so a sitting is a fair sample of the paper rather than a run of whatever you happened to be weakest on.
AZ-400 practice exam 40 questions are free, and they are spread across all five domains rather than taken from the front of the bank, so the preview shows you the hardest area as well as the easiest one. No account switch and no card needed to see them.
The most advanced examination and certification readiness platform available. Train autonomously, pass effortlessly.
