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.

The correct native GitHub Actions method for passing files between jobs in the same workflow is artifact storage. Workflow artifacts are designed to persist files produced by one job so they can be downloaded and used by another job later in the workflow. Job outputs are better suited for passing small values, strings, IDs, flags, or metadata between jobs, not full files. Caching is intended to speed up repeated workflow runs by reusing dependencies or build outputs; it is not the proper mechanism for transferring job-produced files. An external blob store can work architecturally, but it is not the native GitHub Actions method. Therefore, artifact storage is the best and most exam-aligned answer for passing files between jobs.

GitHub automatically creates a GITHUB_TOKEN for workflow jobs so the workflow can authenticate to GitHub without requiring a separately maintained personal access token for many repository-scoped operations. A common use is making authenticated REST API, GraphQL API, or GitHub CLI requests against resources that the token has permission to access. The token ' s capabilities are governed by the workflow ' s permissions configuration and the repository or organization policy. It is not an SSH credential for connecting to a runner, and it is not required merely to read encrypted repository secrets that GitHub makes available through the secrets context. Likewise, simply invoking a public Marketplace action does not inherently require explicitly passing GITHUB_TOKEN. Therefore, making authenticated GitHub API calls is the correct use described by option A.

================

The $GITHUB_OUTPUT file is used to pass data from one step to another in GitHub Actions. The echo command appends the key-value pair to this file, which sets the output variable (MY_OUTPUT) for the current step.
