Microsoft GitHub Actions Exam GH-200 Exam Dumps: Updated Questions & Answers (October 2026)

A job using runs-on: [gpu] depends on an available runner matching that label. If the workflow previously succeeded but now remains waiting, the runner ' s availability, registration, connectivity, or label assignment should be investigated. GitHub stores self-hosted runner application diagnostic logs in the runner installation ' s _diag directory; Runner_ log files provide details about runner startup, connectivity, registration, and update activity, making option A useful. Checking the Set up job information from a previous successful run can also identify which runner previously accepted the job, providing a concrete target for investigation. Rotating GITHUB_TOKEN does not repair runner scheduling because job assignment does not depend on manually rotating that workflow token. GitHub-hosted usage limits are similarly unrelated to a custom gpu runner label. Therefore, A and C are appropriate troubleshooting actions.

The GET /repos/:owner/:repo/actions/runs/:run_id/logs API endpoint is used to retrieve the logs of a specific workflow run identified by run_id. This is the correct method for downloading logs from a workflow run.

The needs context is used to reference the outputs of jobs that are dependencies of the current job. In this case, needs.job1.outputs.output1 correctly accesses the output of output1 from the job job1 in the dependent job.

Using a corporate secret store like HashiCorp Vault provides a secure, centralized location for sensitive information. GitHub Actions can then retrieve and store the token securely during deployment by setting it as an environment variable, ensuring the token remains secure and accessible at runtime.

Storing the token as an organizational-level encrypted secret in GitHub ensures it is accessible across multiple repositories, minimizing management overhead. GitHub Actions can then use this secret during deployment by setting it as an environment variable, allowing the microservice to access it securely at runtime.

For a run step in a composite action, GitHub Actions supports the working-directory property to specify the directory in which the command executes. The property belongs to the individual step, alongside properties such as run and shell. The generic keyword directory is not part of GitHub Actions metadata syntax. Composite actions declare runs.using: composite, after which runs.steps defines the reusable sequence of commands or actions. An input such as inputs.dir can therefore be referenced through an expression and assigned to working-directory. GitHub ' s action metadata reference explicitly defines runs.steps[*].working-directory as the supported property for controlling the execution directory of a composite-action command. Therefore, option B is the valid implementation.

The Actions tab on the main page of the repository is where you can find detailed information about the workflow runs, including step failures and build logs. You can review the status of each job and step within the workflow, see the failure messages, and access logs for debugging.

The runs-on keyword allows you to specify the operating system and other labels for the runner. By specifying self-hosted, windows, and x64, you are targeting a self-hosted Windows runner that matches these criteria, which aligns with the custom configuration of your self-hosted runner.

In a Docker container action, the action.yml file includes the runs.using field, which is set to docker to specify that the action runs inside a Docker container. This is the key indicator that the action is a Docker container action.

To use a starter workflow provided by your organization, you need to go to the Actions tab in the repository and select New workflow. This option allows you to either create a new workflow or select from a list of available workflow templates, including starter workflows provided by your organization.

For a JavaScript action using the official @actions/core toolkit, core.setFailed(error.message) is the documented method for reporting an exception and marking the action as failed. setFailed() logs the supplied message and sets a failing exit code so GitHub records the action and associated check run as unsuccessful. Neither core.setException() nor core.action.setException() exists in the supported @actions/core API, and action.setError() is likewise not the documented error-handling method. The source PDF visibly contains the first three choices but crops the final distractor; the missing fourth choice was reconstructed from the matching public GH-200 question listing, while the correct answer itself was independently verified against GitHub ' s official documentation. GitHub ' s JavaScript-action example uses this exact catch pattern.
