The Microsoft GH-200 - GitHub Actions Exam is part of the Microsoft GitHub Certifications track and is designed for professionals who work with GitHub Actions in real-world automation scenarios. It focuses on building, reusing, and managing workflows and actions, along with enterprise-level administration. This exam matters for candidates who want to validate practical skills in CI/CD automation and GitHub Actions implementation.
| # | Exam Topics | Sub-Topics | Approximate Weightage (%) |
|---|---|---|---|
| 1 | Author and maintain workflows | Workflow syntax and structure, triggers and events, job and step configuration | 30% |
| 2 | Consume workflows | Reuse workflows, call workflow inputs and outputs, manage workflow dependencies | 25% |
| 3 | Author and maintain actions | Create custom actions, action metadata, JavaScript and composite actions | 25% |
| 4 | Manage GitHub Actions in the enterprise | Enterprise policy controls, permissions and secrets, runner and usage management | 20% |
This exam tests both conceptual understanding and hands-on ability. Candidates should be able to build and maintain workflows, reuse actions effectively, and apply enterprise controls with confidence. It also checks how well you can solve practical GitHub Actions tasks under exam conditions.
Which default GitHub environment variable indicates the owner and repository name?
The GITHUB_REPOSITORY environment variable contains the owner and repository name in the format owner/repository. It is automatically provided by GitHub Actions and can be used to reference the repository in workflows.
As a developer, you are designing a workflow and need to communicate with the runner machine to set environment variables, output values used by other actions, add debug messages to the output logs, and other tasks. Which of the following options should you use?
Workflow commands are special commands that allow you to interact with the runner, set environment variables, output values, add debug messages, and perform other tasks within the workflow. These commands are used to modify the environment or influence the behavior of the GitHub Actions runner.
As a DevOps engineer, you are developing workflows to build an application. You have a requirement to create the build targeting multiple node versions. Which code block should you use to define the workflow?
The correct GitHub Actions syntax for running a job across multiple Node.js versions is strategy.matrix. The matrix values are referenced at runtime through the matrix context, so node-version: ${{ matrix.node-ver }} is correct. Option A defines the matrix correctly but references it incorrectly through strategy.node-ver; matrix values are not accessed through the strategy context. Option C uses matrix-strategy, which is not a valid GitHub Actions workflow key. Option D reverses the structure by putting strategy under matrix, which is invalid. This question tests matrix strategy syntax, dynamic job configuration, and using matrix values as inputs to actions such as actions/setup-node. GitHub defines jobs.<job_id>.strategy.matrix as the proper matrix mechanism.
You are reaching your organization's storage limit for GitHub artifacts and packages. What should you do to prevent the storage limit from being reached?
To prevent reaching the storage limit for GitHub artifacts and packages, you should manage and clean up artifacts and packages stored in repositories owned by your organization. This includes deleting unnecessary artifacts and managing the lifecycle of packages, as they contribute directly to your organization's storage quota.
Which two actions ensure that a GitHub Actions workflow can be triggered manually? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
The correct manual trigger for a GitHub Actions workflow is workflow_dispatch. Defining workflow_dispatch under the on key enables the workflow to be started manually from the GitHub UI, GitHub CLI, or API. Inputs are optional but valid; they allow the user to provide values when manually starting the workflow, so option A is also correct. A schedule trigger is for cron-based automatic execution, not manual execution. workflow_call is used to make a workflow reusable by another workflow; it does not create the manual ''Run workflow'' button. Therefore, A and C are the correct selections. GitHub's documentation confirms that manual workflows require workflow_dispatch and can include custom inputs.

The practice test gives you a real exam simulation so you can get familiar with the format, pacing, and question style before test day. With up-to-date questions and verified answers, you can study smarter and reduce guesswork. The timed practice also improves time management, which is important when aiming to pass the exam on your first attempt.
It is a Microsoft GitHub Certifications exam focused on GitHub Actions skills, including workflows, reusable workflows, actions, and enterprise management.
It is for candidates who work with GitHub Actions and want to validate their ability to build and manage automation workflows in practical environments.
The difficulty depends on your experience with GitHub Actions. Candidates with hands-on practice usually find it easier to handle workflow and enterprise questions.
Braindumps alone are not the best approach. You should use them as a study aid together with hands-on practice and a solid understanding of the exam topics.
Yes, hands-on experience is strongly recommended because the exam is centered on practical GitHub Actions knowledge and workflow implementation.
They help you review likely exam-style questions, verify your answers, and practice under timed conditions so you can build confidence before the real test.
