Microsoft Certified: DevOps Engineer Expert
DevOps Engineer Expert is the Microsoft exam least about Azure and most about how a team works. Source control strategy, pipelines, release safety, feedback and instrumentation take up the bulk of it.
It requires an associate certificate first, and the route most people used has changed.

The study guide puts well over half the weight on development processes and continuous delivery, with security, dependency management, instrumentation and collaboration sharing the rest. That distribution matters when choosing preparation, because candidates instinctively revise Azure services and the exam mostly asks about branching strategies, approval gates, deployment patterns and what to do when a release goes wrong at two in the afternoon.
Tooling questions span both Azure DevOps and GitHub, which now overlap considerably. Expect to reason about pipelines in either, about artefact feeds and secrets handling, and about dependency scanning as a delivery concern rather than a security afterthought. The vocabulary is Microsoft's; the practices are the industry's, which is why this paper travels better than its name suggests.
One route change is worth knowing before you plan. The prerequisite is any one of the qualifying associate certificates, and the developer path that many candidates used was retired during 2026, which leaves the Administrator certificate as the practical entry for most people. Check what you already hold before assuming the path you remember still exists.
Who it actually suits
People who already own a pipeline, or are about to. If your team ships by hand and you want that to change, the syllabus doubles as a reasonable agenda for the change. If you are a developer hoping it will read as seniority, be warned that it says more about process than about code, and interviewers who know the exam will ask what you have automated rather than what you have passed. Administrators moving toward delivery work get the most from it, because the half they lack is exactly the half it weights.
| Skill area | Share | The question it keeps asking |
|---|---|---|
| Design and implement build and release pipelines | 50 to 55 % | What runs, in what order, with what gate, and how it rolls back |
| Design and implement processes and communications | 10 to 15 % | How work flows, how it is tracked, and how a team learns from a failure |
| Design and implement a source control strategy | 10 to 15 % | Branches, merges, and what protects the main line |
| Develop a security and compliance plan | 10 to 15 % | Secrets, dependencies, and who may approve what |
| Implement an instrumentation strategy | 5 to 10 % | What you would want to know at two in the afternoon, and whether you can see it |
- 3 March 2026: Microsoft announces the retirement of the Azure Developer Associate exam, one of the two routes into this certificate.
- 31 July 2026: that exam retires. Anyone who already holds the developer certificate still qualifies.
- From August 2026: new candidates enter through the Azure Administrator Associate certificate, which has no prerequisite of its own.
- Every year afterwards: two free renewal assessments, one for each certificate, each inside its own half-year window, and a lapse of either means a full-price resit.
One toolchain, two names
The exam treats Azure DevOps and GitHub as alternatives rather than rivals, and a scenario may describe either. A candidate fluent in one and blank on the other should spend a fortnight in the second before booking, because the questions about artefacts, secrets and approvals assume you can read the pipeline in front of you whichever product drew it. The concepts are identical; the vocabulary and the screens are not.
One hundred minutes, an unfixed number of questions, scenario cases and drag-and-drop items with a lab possible, a scaled 700 to pass, nine editions with German included, Pearson VUE, and a country-priced fee: the facts are the standard ones for a Microsoft role-based paper. What is not standard is the subject. Over half of this exam would make sense to a team that has never touched Azure, and that alone justifies sitting it even where the platform is not the point: the certificate is Microsoft's, and the delivery discipline it examines belongs to everyone.
What a question looks like
Written by us in the exam's style. It is not a real question from any question bank, and we do not publish those.
A team releases weekly and has begun failing in production on changes that passed every test. Investigation shows the failures involve configuration differences rather than code. The team wants to catch these before customers do, without lengthening the release cycle. What change to the pipeline addresses the cause?
Every option improves something. More testing catches more code defects and would not catch this; a manual approval slows the cycle the team asked to protect; rolling back faster treats the symptom. The question is whether you recognise that configuration drift between environments is its own class of problem with its own class of remedy, which is the sort of judgement the exam prizes over tool knowledge.
What it costs to get and to keep

|---|---|---|
| Exam fee | 165 USD | United States price; Microsoft charges by the country where the exam is proctored (read 12 September 2026) |
| Exam fee, Germany and Austria | 126 EUR | read from the Microsoft Learn country selector (read 8 September 2026) |
| Prerequisite certificate | 165 USD | one qualifying associate certificate is required first. The developer route retired during 2026, so for most candidates this means the Administrator exam (read 12 September 2026) |
| Annual renewal, both certificates | not published | free unproctored assessments, one per certificate, each opening only in the six months before its own expiry (read 12 September 2026) |
How much preparation, from where you are
- You maintain build and release pipelines already
- Most of the syllabus is your week described in Microsoft's words. Concentrate on the areas your organisation has never needed, typically dependency management and the instrumentation section.
- You administer Azure and want to move toward delivery
- The best fit for this paper, and the largest genuine gain. Branching strategy and release patterns will be new, and they are the half carrying most of the marks.
- You write code and deploy through somebody else's pipeline
- Expect the process material to feel abstract. Build a pipeline of your own for something small before booking, because the questions assume you have watched one fail.
What passing this does not prove
- Whether you write good software; nothing here examines code quality.
- Whether your pipeline is fast, which is the complaint teams actually have.
- Operating what you deployed once it is live, beyond instrumenting it.
- Anything specific to the tools you have not chosen, which makes the exam broad and occasionally shallow.
Against the alternatives
- DVA-C02 — AWS Certified Developer – Associate
- AWS keeps delivery inside its developer exam rather than giving it a separate expert paper. That one asks more about the SDK; this one asks more about process, and neither is a substitute for the other.
- CKA — Certified Kubernetes Administrator (CKA)
- A sharper signal for anyone whose delivery target is Kubernetes, since it is examined on a live system instead of by selecting answers. Different claim entirely: this proves you can describe a pipeline, that proves you can operate a cluster.
- AZ-305 — Microsoft Certified: Azure Solutions Architect Expert
- The other expert paper from the same prerequisite. Architecture decides how the platform is shaped; this decides how software reaches it.
AZ-400 — quick answers
Which prerequisite do I need now?
Any one of the qualifying associate certificates, but the developer path many people planned around retired during 2026. For most candidates that leaves the Administrator certificate as the realistic entry, so confirm what still qualifies before booking anything.
Is it an Azure exam or a DevOps exam?
More the second than the first, which is unusual for this vendor. Over half the weight sits on development process and continuous delivery, and the practices transfer to teams that do not use Azure at all. That is also why revising services is the wrong preparation.
Does GitHub feature?
Substantially. The two toolchains have converged and the exam treats them as alternatives rather than rivals, so expect to reason about pipelines, artefacts and secrets in both.
Will it make me a DevOps engineer?
It will make you conversant with the practices, which is not the same thing. The job is judged on what you have automated and what happened when it broke. Use the syllabus as an agenda for real work, then let the exam confirm it.
I hold the retired developer certificate. Does it still count?
Yes. Microsoft's announcement made clear that existing holders of the Azure Developer Associate certificate continue to satisfy the prerequisite. What changed is the route for new candidates, who now come through the Administrator certificate.

Concepts this exam draws on
Glossary entries with the reason each one matters for AZ-400.
- Containers
Container builds, registries and Kubernetes deployments in pipelines.
- Serverless Computing
Deploying functions through DevOps pipelines.
- Cloud Hosting
Infrastructure as code targets Azure compute of every kind.
- Git
Source-control strategy is a named skill area: branching models, protection of the main line, and history that stays readable.
- REST API
Pipelines call and are called through APIs, and the exam expects you to read a definition and wire an integration.
- Kubernetes
Deployment targets include clusters, and the paper asks how a rollout to one is staged and reversed.
