GH-200 Exam Dumps : GitHub Actions Exam

The correct syntax for referencing a versioned action is owner/repository@ref. Therefore, to use version v1 of actions/javascript-action, the workflow step must use actions/javascript-action@v1. The @v1 portion is the ref, which can represent a tag, branch, or commit SHA depending on how the action publisher releases the action. Option A incorrectly treats the version as part of the repository path. Option B invents a separate version: key, which is not how action versions are selected. Option C changes the repository name and does not specify a ref. In GitHub Actions syntax, uses selects an action, and version selection is part of the action reference itself. GitHub examples use the uses: owner/action-name@ref form.

For a Docker container action to run in a GitHub Actions workflow, the runner must have Docker installed. The runs-on attribute of the job should specify an environment that supports Docker, typically a Linux environment (e.g., ubuntu-latest), since Docker is widely supported and commonly used in Linux-based environments.

A non-zero exit code is used to set the status of an action to " failed " in GitHub Actions. When the action ' s script or code exits with a non-zero status, it indicates failure, and GitHub will mark the action as failed.
