The GitHub Actions Exam (GH-200) is designed for developers and DevOps engineers who build, maintain, and manage CI/CD workflows using GitHub Actions within the Microsoft GitHub Certifications program. This exam validates your ability to author workflows, consume existing actions, create custom actions, and implement GitHub Actions at enterprise scale. This landing page provides a clear roadmap of exam topics, question formats, and practical preparation strategies to help you succeed.
Use this topic map to guide your study for Microsoft GH-200 (GitHub Actions Exam) within the Microsoft GitHub Certifications path.
The GH-200 exam measures both conceptual knowledge and practical reasoning through a mix of question types that reflect real-world scenarios.
Questions increase in complexity and emphasize practical application, ensuring candidates can handle real production workflows and enterprise-level challenges.
Effective preparation for GH-200 requires structured study aligned to the four core topic areas, combined with hands-on practice and timed mock exams. Dedicate 4-6 weeks to build both breadth and depth across workflows, actions, and enterprise management.

Authoring and maintaining workflows typically comprises 35-40% of the exam, as this is the foundation of GitHub Actions use. Managing GitHub Actions in the enterprise also carries significant weight (25-30%), reflecting the shift toward organizational governance. The remaining topics are distributed across consuming workflows and authoring custom actions, so a balanced study approach is essential.
In practice, you author workflows to define your CI/CD pipeline, consume existing actions from the Marketplace to speed up common tasks, and create custom actions when your organization has unique requirements. Enterprise management sits across all three, ensuring security, cost control, and compliance. Understanding these connections helps you see the exam as a cohesive skill set rather than isolated topics.
Hands-on experience with GitHub Actions is highly valuable; ideally, you should have built and run at least 3-5 workflows before the exam. Prioritize labs that cover workflow syntax and triggers, custom action creation, and secret management in multi-team environments. Building a real project (even a small one) that uses multiple actions and enterprise features will reinforce concepts far better than reading alone.
Candidates often confuse workflow syntax (especially conditional expressions and matrix strategies), misunderstand action versioning best practices, or overlook enterprise-level features like runner groups and organization secrets. Another frequent error is not fully reading scenario-based questions, which can lead to choosing a technically correct but contextually wrong answer. Slow reading and rushing through simulations also cause avoidable mistakes.
In the final week, focus on weak topic areas identified in your practice tests rather than re-reading strong topics. Run through one full-length timed mock exam, then spend time reviewing explanations for any missed questions. Create a quick reference sheet for syntax, common action patterns, and enterprise policies. On the day before the exam, do a light review and get adequate rest rather than cramming new material.
You are a developer, and your container jobs are failing on a self-hosted runner. Which requirements must you check to ensure that the self-hosted runner is properly configured? (Choose two.)
While Docker can run on various operating systems, Linux is often the most common and preferred OS for containerized workloads. Docker works well on Linux and is a widely-used platform for running containers.
For container jobs to run on a self-hosted runner, Docker must be installed and properly configured on the runner. Docker is required to build and run containerized workloads in a GitHub Actions workflow.
How can GitHub Actions encrypted secrets be used in if: conditionals within a workflow job?
GitHub Actions encrypted secrets can be accessed in workflows using the secrets context. You can directly reference the secret within an if: conditional using ${{ secrets.MySuperSecret }} to determine whether a job or step should run based on the secret's value.
What are the two types of environment protection rules you can configure? (Choose two.)
Required reviewers is a protection rule where you can specify that certain individuals or teams must review and approve the workflow run before it can proceed. This is used to enforce approvals before certain steps or environments are accessed.
Wait timer is a protection rule that introduces a delay before a workflow can proceed to the next stage. This is useful for adding time-based constraints to the deployment process or ensuring that certain conditions are met before a workflow continues.
What metadata file in a custom action defines the main entry point?
The action.yml file is the metadata file in a custom GitHub Action that defines the main entry point, including information such as the inputs, outputs, description, and the runs key that specifies the main entry point (e.g., a script or a Docker container).
Which workflow command would output the debug message "action successfully debugged"?
The ::debug:: syntax is used to output debug messages in GitHub Actions workflows. This command will print the message 'action successfully debugged' in the debug logs when the workflow runs.
