AZ-400 is Microsoft's expert-level DevOps credential — paired with either AZ-104 or AZ-204 to confer the Microsoft Certified: DevOps Engineer Expert title. It validates the ability to design and implement DevOps practices at scale: build and release pipelines (Azure DevOps and GitHub Actions), source-control strategy, security and compliance integration (DevSecOps, Microsoft Defender for DevOps), instrumentation, and team / process design. The audience is senior platform engineers, SREs, and lead developers responsible for delivery pipelines across multiple teams. Expect 40–60 questions in 120 minutes including drag-and-drop, hot-area, multiple-response, and at least one case study with scenario-driven items.
Largest domain by far at 52%. Azure Pipelines and GitHub Actions (YAML, templates, agent pools, environments, approvals), package management, IaC (Bicep / Terraform / ARM), database deployments, secret management, and progressive-delivery patterns (blue-green, canary, feature flags).
About 12%. Agile / Scrum implementation in Azure Boards / GitHub Projects, work-item flow, value-stream mapping, and stakeholder communication patterns.
About 12%. Git branching strategies (trunk-based, GitHub flow, GitFlow), repo structure (monorepo vs. multi-repo), pull-request policies, code-owner requirements, and large-file / submodule handling.
About 12%. DevSecOps integration: Microsoft Defender for DevOps, GitHub Advanced Security (CodeQL, secret scanning, dependency review), SBOMs, supply-chain security, and policy-as-code.
About 12%. Application Insights, Azure Monitor, Log Analytics, distributed tracing, dashboards, alerts, and SRE-style SLO / error-budget design.
$130k–$175k–$240k USD annual
AZ-400 is one of the highest-paying Microsoft certs in the market. Range covers US-based senior DevOps engineers; FAANG / fintech / Microsoft-partner principal SREs and platform engineers often clear $300k TC. Cert is a screening signal; demonstrated production DevOps and SRE leadership drive the high end.

AZ-400 is the canonical DevOps credential for Azure-aligned platform organizations and one of the most-requested expert-level Microsoft certs in senior engineering JDs. Recruiters at financial services, healthcare, government, and Microsoft-partner consultancies use it as evidence that a candidate can credibly design pipelines, source-control strategy, and security integration across multiple teams. It pairs naturally with AZ-104 (most common pairing) or AZ-204 (developer-track pairing) to confer the DevOps Engineer Expert title. Many candidates add AZ-500 for security-leaning DevSecOps roles or AZ-305 to broaden into architecture work.
AZ-400 is the only Microsoft expert-level cert that requires a co-cert: candidates must hold either AZ-104 (Administrator Associate) or AZ-204 (Developer Associate) to be awarded the Microsoft Certified: DevOps Engineer Expert title. The exam itself can be taken in any order, but the Expert title is only granted once both are held.
Microsoft recommends three to five years of professional development or operations experience, including significant time with Azure DevOps Services, GitHub Actions, and at least one IaC tool (Bicep, Terraform, ARM). The official Microsoft Learn path covers all five domains in roughly 40–50 hours. Hands-on lab time across both Azure DevOps Services and GitHub is essentially required — Microsoft has aggressively expanded GitHub Actions coverage in recent refreshes, so candidates whose only experience is Azure Pipelines should plan extra time on GitHub-specific scenarios.
AZ-400 sits in the Expert tier — Microsoft's top difficulty band, alongside AZ-305 and SC-100. Plan on 100–140 hours of study over 10–14 weeks with senior DevOps experience and prior Azure exposure; substantially longer without that background. The exam runs about 120 minutes with 40–60 questions in multiple-choice, multiple-response, drag-and-drop, hot-area, and case-study formats. Case studies are timed separately and cannot be revisited once you move past them.
The most common stumbling block is keeping Azure DevOps and GitHub Actions distinctions straight — Microsoft's recent refreshes have rebalanced toward GitHub Actions and the unified GitHub Advanced Security toolchain, so candidates with deep ADO experience but light GitHub exposure (or vice versa) often need to backfill. The build-and-release domain at 52% means pipeline-design fluency is the single highest-leverage area to study.
Most recent skills-measured update. Expanded GitHub Actions coverage, added Microsoft Defender for DevOps and GitHub Advanced Security, modernized supply-chain-security framing. Microsoft refreshes AZ-400 approximately every 12–18 months without changing the exam code.
Restructured into the current five-domain layout, rebalanced the build-and-release pipelines domain to 52% weight, and integrated GitHub-first content alongside Azure DevOps.

AZ-400 (Microsoft Azure DevOps Engineer Expert) is a a challenging, scenario-heavy exam that requires deep hands-on experience and the ability to make architectural trade-off decisions Expert-level exam. Most candidates need 150–300 hours of study spread over 3–6 months for professional and expert-level exams. These exams typically expect prior associate-level proficiency. Most candidates who score consistently above the passing threshold on practice exams pass on their first attempt.
