The Microsoft AZ-400 exam is the gateway to the Azure DevOps Engineer Expert credential, and it is one of the harder Microsoft certifications to pass on the first attempt. If you want to know how to pass AZ-400 in 2026 without wasting months on the wrong material, this 12-week study plan breaks the whole syllabus into manageable weekly blocks and tells you exactly what to focus on.
AZ-400 is an expert-level exam, so it assumes you already work with Azure day to day. It is not a memory test. It rewards people who genuinely understand pipelines, source control and site reliability, and it punishes anyone hoping to cram their way through. The good news is that with a structured plan and consistent practice, twelve weeks is enough time to go from confident Azure user to certified DevOps engineer.
What Is the AZ-400 Exam and Who Is It For?
AZ-400 (Designing and Implementing Microsoft DevOps Solutions) is the single exam that earns the Microsoft Certified: DevOps Engineer Expert certification. It targets people who combine development and operations skills to deliver software faster and more reliably.
You are a good fit for AZ-400 if you already do most of the following in your job:
- Build and maintain CI/CD pipelines in Azure Pipelines or GitHub Actions
- Manage source control with Git, including branching strategies and pull requests
- Automate infrastructure with infrastructure as code
- Implement security and compliance controls in the delivery process
- Monitor applications and track reliability metrics
If you are brand new to Azure, start with a fundamentals or associate exam first. AZ-400 is designed for practitioners, not beginners.
Exam Tip: AZ-400 tests both Azure DevOps and GitHub. Microsoft expects you to know Azure Pipelines and GitHub Actions, plus the integration patterns between them. Do not study only one platform.
AZ-400 Exam Facts You Need to Know
Before you plan your study, get the numbers straight. Here are the current AZ-400 exam details for 2026.
| Detail | AZ-400 (2026) |
|---|---|
| Certification earned | Microsoft Certified: DevOps Engineer Expert |
| Number of questions | 40 to 60 |
| Passing score | 700 out of 1000 |
| Time limit | 120 minutes (extension available for non-native speakers) |
| Exam cost | 165 USD (regional pricing varies) |
| Question types | Single choice, multiple choice, drag and drop, case studies |
| Prerequisite | Active AZ-104 or AZ-204 for the Expert badge |
The passing score of 700 is scaled, so it does not map to a simple percentage. Treat anything below 80 percent on your practice exams as a signal that you are not ready yet.
Exam Tip: You can sit AZ-400 before you hold AZ-104 or AZ-204, but Microsoft will not award the Expert badge until you also have an active associate certification. Plan your certifications so the badge is not left in limbo.
The 2026 AZ-400 Update: What Changed
The English version of AZ-400 is being updated on 27 July 2026, so the objectives you study depend on when you book. This matters for your prep because the refreshed exam leans harder into modern DevOps practice.
The 2026 update sharpens the focus on:
- Site reliability engineering (SRE): expect questions on service level objectives (SLOs), error budgets and reliability metrics.
- Security-first delivery: shifting security left, supply chain security and compliance baked into pipelines.
- Observability: instrumentation, telemetry and monitoring as a first-class concern rather than an afterthought.
- Automation and cloud-native patterns: less manual configuration, more repeatable infrastructure as code.
There is also a prerequisite change worth planning around. AZ-204 (Azure Developer Associate) retires on 31 July 2026. If you pass AZ-204 before then, it permanently satisfies the AZ-400 prerequisite. After that date the standard route is AZ-104, and AI-200 is being added as an accepted prerequisite once it reaches general availability. For the full picture on the AZ-204 change, read our guide on why AZ-204 is being replaced by AI-200.
Exam Tip: If you are studying against the updated objectives, make SRE and observability non-negotiable revision topics. They are the newest additions and the easiest marks to leave on the table if you skip them.
The AZ-400 Domains and Their Weightings
AZ-400 is organised into functional groups. The continuous integration and continuous delivery areas carry the most weight, so they deserve the most study time.
| Domain | Approximate weight |
|---|---|
| Define and implement continuous integration | 20 to 25% |
| Define and implement continuous delivery and release management | 10 to 15% |
| Develop a security and compliance plan | 10 to 15% |
| Manage source control | 10 to 15% |
| Facilitate communication and collaboration | 10 to 15% |
| Develop an instrumentation strategy | 5 to 10% |
| Develop a site reliability engineering (SRE) strategy | 5 to 10% |
Continuous integration and continuous delivery together make up roughly a third to nearly half of the exam depending on the version. This is where your study hours should concentrate. If you can design a pipeline in your sleep, you are most of the way to a pass.
The 12-Week AZ-400 Study Plan
This plan assumes one to two hours of study on weekdays and a longer hands-on session at the weekend. Adjust the pace to your experience: seasoned DevOps engineers may compress it to six or eight weeks, while those new to Azure Pipelines should not rush it.
Weeks 1 to 2: Foundations and Source Control
Start with the plumbing that everything else sits on.
- Review the official AZ-400 skills measured document and note which version you are studying against.
- Set up a free Azure DevOps organisation and a GitHub account so you can practise for real.
- Master Git fundamentals: branching strategies (trunk-based, GitFlow), pull requests, merge versus rebase.
- Learn repository management, branch policies and permissions in both Azure Repos and GitHub.
By the end of week 2 you should be able to explain when to use each branching strategy and configure branch protection.
Weeks 3 to 5: Continuous Integration
This is the single biggest scoring area, so give it three full weeks.
- Build YAML pipelines in Azure Pipelines from scratch.
- Create equivalent workflows in GitHub Actions and understand how they map across.
- Practise with build agents, self-hosted versus Microsoft-hosted, and agent pools.
- Handle package management with Azure Artifacts, dependency caching and versioning.
- Integrate automated testing and code quality gates into the build.
Do not just read about pipelines. Build at least five of them with increasing complexity.
Weeks 6 to 7: Continuous Delivery and Release Management
- Design multi-stage release pipelines with approvals and gates.
- Implement deployment strategies: blue-green, canary and rolling deployments.
- Work with deployment targets including Azure App Service, Azure Kubernetes Service and virtual machines.
- Manage secrets and configuration with Azure Key Vault and variable groups.
Weeks 8 to 9: Security, Compliance and Infrastructure as Code
- Shift security left with static analysis, dependency scanning and secret detection.
- Understand supply chain security and how to secure the pipeline itself.
- Practise infrastructure as code with ARM templates, Bicep and an introduction to Terraform.
- Apply compliance controls and policy as code.
Week 10: Instrumentation and Site Reliability Engineering
This is the area most candidates underprepare, and the 2026 update made it more important.
- Configure Application Insights and Azure Monitor for telemetry.
- Define service level objectives (SLOs) and understand error budgets.
- Set up alerts, dashboards and log queries with Kusto Query Language basics.
- Learn how SRE principles influence release decisions.
Week 11: Communication, Collaboration and Weak Spots
- Review Azure Boards, work item tracking and Agile process management.
- Revisit your two lowest-scoring practice domains and drill them.
- Read every case study style question you can find, since AZ-400 uses scenario questions heavily.
Week 12: Full Practice Exams and Final Review
- Sit full-length timed practice exams under exam conditions.
- Aim for a consistent 85 percent or higher before you book.
- Review every wrong answer and understand why the correct option wins.
- Skim the skills measured list one last time and confirm no domain is neglected.
Exam Tip: AZ-400 relies on case study and scenario questions where several answers look plausible. Practise reading the requirements carefully and eliminating options that violate a stated constraint. That skill alone can move you from a near miss to a comfortable pass.
Common Reasons People Fail AZ-400
Knowing the traps helps you avoid them. Candidates most often come unstuck because they:
- Study only Azure DevOps and ignore GitHub. The exam expects both, plus their integration.
- Underestimate SRE and instrumentation. These smaller domains are easy marks that people skip.
- Read instead of build. AZ-400 is practical. You must create pipelines, not just watch tutorials.
- Rely on brain dumps. Dumps teach you nothing and often contain outdated or wrong answers, especially after the 2026 update.
- Book too early. If your practice scores sit below 80 percent, you are not ready.

How to Practise for AZ-400 the Smart Way
Reading and video courses build knowledge, but practice questions build exam readiness. The gap between understanding a topic and answering a tricky scenario question about it under time pressure is exactly what practice tests close.
Use practice questions to:
- Find your weak domains early so you can rebalance your study time.
- Get comfortable with Microsoft's scenario and case study phrasing.
- Build the timing discipline you need to finish 40 to 60 questions in 120 minutes.
- Confirm you are genuinely ready before you spend 165 USD on the real thing.
