Microsoft GH-200 Exam Domains Q&A

Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.

Question 1 Microsoft GH-200
QUESTION DESCRIPTION:

What is the smallest scope for an environment variable?

  • A.

    the workflow settings

  • B.

    a step

  • C.

    a job

  • D.

    the workflow env mapping

Correct Answer & Rationale:

Answer: B

Explanation:

The smallest scope for an environment variable is within a step . Environment variables defined within a step are only accessible to that particular step, which makes it the smallest scope for a variable in a GitHub Actions workflow.

Question 2 Microsoft GH-200
QUESTION DESCRIPTION:

Which of the following scenarios would require the use of self-hosted runners instead of GitHub-hosted runners?

  • A.

    running more than the three concurrent workflows supported by GitHub-hosted runners

  • B.

    exceeding 50,000 monthly minutes of build time

  • C.

    using Docker containers as part of the workflow

  • D.

    using specialized hardware configurations required for workflows

  • E.

    performing builds on macOS

Correct Answer & Rationale:

Answer: A, D

Explanation:

GitHub-hosted runners have a limit on the number of concurrent workflows (typically 20 for free-tier accounts and 5 for enterprise). If your organization needs to run more workflows simultaneously, you would need to use self-hosted runners to increase the available concurrency.

Self-hosted runners allow you to configure specialized hardware or software setups that are necessary for certain workflows. GitHub-hosted runners may not have access to custom hardware configurations like GPUs or other specialized resources, so self-hosted runners are required in such cases.

Question 3 Microsoft GH-200
QUESTION DESCRIPTION:

When creating and managing custom actions in an enterprise setting, which of the following is considered a best practice?

  • A.

    creating a separate repository for each action so that the version can be managed independently

  • B.

    creating a separate branch in application repositories that only contains the actions

  • C.

    creating a single repository for all custom actions so that the versions for each action are all the same

  • D.

    including custom actions that other teams need to reference in the same repository as application code

Correct Answer & Rationale:

Answer: A

Explanation:

Creating a separate repository for each custom action allows you to manage the versioning independently for each action. This approach provides flexibility, as each action can be updated, tested, and versioned separately, avoiding potential conflicts or dependencies between different actions.

Question 4 Microsoft GH-200
QUESTION DESCRIPTION:

As a developer, your self-hosted runner sometimes looses connection while running jobs. How should you troubleshoot the issue affecting your self-hosted runner?

  • A.

    Set the DEBUG environment variable to true before starting the self-hosted runner to produce more verbose console output.

  • B.

    Locate the self-hosted runner in your repository ' s settings page and download its log archive.

  • C.

    Access the self-hosted runner ' s installation directory and look for log files in the _diag folder.

  • D.

    Start the self-hosted runner with the --debug flag to produce more verbose console output.

Correct Answer & Rationale:

Answer: C

Explanation:

When troubleshooting a self-hosted runner, you can access the _diag folder located in the self-hosted runner ' s installation directory. This folder contains diagnostic logs that can help you identify the root cause of issues, such as connection problems.

Question 5 Microsoft GH-200
QUESTION DESCRIPTION:

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?

  • A.

    via the .github repository owned by the organization

  • B.

    via repositories owned by the organization

  • C.

    via the GitHub Marketplace

  • D.

    via a repository owned by a third party

Correct Answer & Rationale:

Answer: B

Explanation:

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.

Question 6 Microsoft GH-200
QUESTION DESCRIPTION:

What will the output be for the following event trigger block in a workflow?

GH-200 Q6

  • A.

    It throws a workflow syntax error, pointing to the types definition in issue_comment event.

  • B.

    It throws a workflow syntax error, pointing to the types definition in issues event.

  • C.

    It runs the workflow when an issue is edited or when an issue comment created.

  • D.

    It runs the workflow when an issue or issue comment in the workflow ' s repository is created or modified.

  • E.

    It runs the workflow when an issue is created or edited, or when an issue or pull request comment is created.

Correct Answer & Rationale:

Answer: C

Explanation:

The provided event trigger block specifies two types of events:

For issues: the workflow triggers on opened or edited issues.

For issue_comment: the workflow triggers when an issue comment is created.

This configuration ensures the workflow will run when either an issue is opened or edited, or an issue comment is created.

Question 7 Microsoft GH-200
QUESTION DESCRIPTION:

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?

  • A.

    environment variables

  • B.

    workflow commands

  • C.

    self-hosted runners

  • D.

    enable debug logging

    E composite run step

Correct Answer & Rationale:

Answer: B

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.

Question 8 Microsoft GH-200
QUESTION DESCRIPTION:

Where should workflow files be stored to be triggered by events in a repository?

    .github/workflows/

    .github/actions/

    Nowhere; they must be attached to an act on in the GitHub user interface

  • D.

    anywhere

  • E.

    .workflows/

Correct Answer & Rationale:

Answer: A

Explanation:

Workflow files must be stored in the .github/workflows/ directory of the repository. This is the standard location for GitHub Actions workflow files, and workflows in this directory are automatically triggered by events defined in the file, such as pushes, pull requests, or other GitHub events.

Question 9 Microsoft GH-200
QUESTION DESCRIPTION:

You are a developer working on developing reusable workflows for your organization. What keyword should be included as part of the reusable workflow event triggers?

  • A.

    check_run

  • B.

    workflow_run

  • C.

    workflow_call

  • D.

    pull_request

Correct Answer & Rationale:

Answer: C

Explanation:

The workflow_call event is used to trigger a reusable workflow from another workflow. This allows you to create workflows that can be reused in multiple places within your organization, enabling better modularity and reducing duplication.

Question 10 Microsoft GH-200
QUESTION DESCRIPTION:

What are the two types of environment protection rules you can configure? (Choose two.)

  • A.

    required reviewers

  • B.

    branch protections

  • C.

    wait timer

  • D.

    artifact storage

Correct Answer & Rationale:

Answer: A, C

Explanation:

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.
