This az 400 study plan allocates study time by Microsoft's published domain weights: roughly half your time on build and release pipelines, since it is 54% of the exam, and the rest split across processes and communications, source control, security and compliance, and instrumentation in proportion to their weight.
A study plan is only useful if it matches how the exam is actually weighted. This az 400 study plan follows the domain percentages on Microsoft's AZ-400 exam page and study guide directly: design and implement build and release pipelines at 54%, processes and communications at 14%, source control strategy at 12%, security and compliance at 12%, and instrumentation at 8%.
How to prepare for AZ 400: the weighting logic
Because build and release pipelines alone outweighs the other four domains combined, every schedule below gives it roughly half the available study time. The remaining time splits across the other domains in proportion to their weight, with instrumentation getting the least since it is the smallest domain. Adjust the plan around your own strengths — if you already administer pipelines daily, shift hours toward security and compliance or source control instead.
AZ 400 course: 4-week plan (fast track)
Use this if you already have solid Azure DevOps and GitHub experience and mainly need to close syllabus gaps.
- Week one: Build and release pipelines — package management, pipeline testing strategy, and YAML pipeline authoring. This is the single biggest block of the entire plan.
- Week two: Continue build and release pipelines — deployment automation, agent and runner infrastructure, trigger rules, and multi-stage job design. Finish with a self-check against the exam objectives.
- Week three: Processes and communications, then source control strategy — flow of work, metrics and dashboards, branching strategy, and branch policies.
- Week four: Security and compliance plus instrumentation, then a full review pass using the sample questions and a timed practice test.
AZ 400 training: 8-week plan (steady pace)
A better fit if you are building Azure DevOps or GitHub Actions skills alongside the syllabus rather than refreshing existing knowledge.
- Weeks one and two: Build and release pipelines, part one — package management strategy, dependency versioning, and quality and release gates. Get hands-on with a real pipeline rather than only reading.
- Weeks three and four: Build and release pipelines, part two — testing strategy, deployment automation choices, agent infrastructure, YAML authoring, and job execution order. This closes out the largest domain.
- Week five: Processes and communications — traceability, feedback cycles, dashboards, and documentation automation.
- Week six: Source control strategy — branching models, pull request workflows, and repository management including large-file handling and permissions.
- Week seven: Security and compliance — authentication and authorization choices, secrets management with Azure Key Vault, and security scanning tools.
- Week eight: Instrumentation, then a full review using sample questions and at least one timed practice test attempt.
AZ 400 study guide: 12-week plan (from the ground up)
Choose this if you are newer to Azure DevOps, GitHub Actions, or both, and need time to build hands-on comfort, not just read about concepts.
- Weeks one to three: Foundations plus the start of build and release pipelines — set up a real Azure DevOps project and a GitHub repository, then work through package management and pipeline testing strategy hands-on.
- Weeks four to six: Finish build and release pipelines — deployment automation, runner and agent choices, YAML pipelines, triggers, and multi-stage job design. Build at least one pipeline from scratch rather than modifying an existing template.
- Week seven: Processes and communications — flow of work, feedback cycles, and DevOps metrics and dashboards.
- Weeks eight and nine: Source control strategy — branching strategies, pull request and branch protection policies, and repository management.
- Weeks ten and eleven: Security and compliance — authentication methods, secrets management, and automated security scanning, plus a light pass on instrumentation.
- Week twelve: Full review — revisit weak domains, work through the sample questions with full explanations, then sit a timed practice test and review every miss against the exam objectives.
Before you commit to a plan
Confirm the prerequisites match your background before choosing a track — someone new to both Azure and DevOps tooling may need longer than twelve weeks, and this plan does not replace hands-on practice with the actual tools. Review the exam format and scoring so you understand what you are studying toward, and check cost and booking once you are ready to schedule.
