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.

When a workflow job targets an environment that has required reviewers, the job enters a waiting state until it is approved or rejected. GitHub Actions does not allow that waiting state to remain indefinitely. If the job is not approved within the allowed period, the workflow fails automatically. The correct duration is 30 days, making option C correct. Options A, B, and D do not match the GitHub Actions environment approval behavior. This is important for deployment governance because required reviewers can block access to protected environments and environment secrets, but pending approvals still have a maximum lifetime.

The simplest official GitHub Actions action type for running shell commands or shell scripts is a composite action. Composite actions allow an action author to combine one or more run steps and reusable workflow commands in an action.yml file without needing to package a Docker image or write a JavaScript action. Option B is correct because it directly supports shell-based automation. Option A is heavier because Docker container actions require a container image or Dockerfile. Option D is used when the action logic is written in JavaScript and executed with Node.js. Option C is incorrect because “Bash script action” is not an official GitHub Actions action type. This topic checks custom action types and reuse patterns.

Scheduled workflows in GitHub Actions are triggered at specified times, and they run on the latest commit of the branch that triggers the workflow. This means the workflow will run on the most recent commit on the branch that was active at the time the scheduled event occurs.
