Prepare for GitHub Actions GH-200 with 75 original, explained practice questions in two timed tests. This course is designed for developers, DevOps engineers, and administrators who automate software delivery with GitHub Actions. The questions focus on choosing the right workflow design and troubleshooting real configuration situations, rather than memorizing a list of buttons. Every question has an answer explanation to make review useful after each attempt.  The bank follows the current official GH-200 study domains. Workflow authoring scenarios cover events, manual inputs, reusable workflows, jobs, dependencies, conditions, matrices, service containers, contexts, outputs, environment files, summaries, caching, and artifacts. Troubleshooting questions ask you to interpret run logs, matrix combinations, missing secrets, inaccessible actions, artifact retention, and the difference between starter and reusable workflows.  Custom action questions compare JavaScript, Docker, and composite actions. They cover action metadata, inputs and outputs, versioning, distribution, and precise references. Enterprise administration scenarios address organization policies, private action access, runner groups, self-hosted runner connectivity, hosted image changes, and secret and variable scopes. Security and optimization questions review least-privilege GITHUB_TOKEN settings, OIDC cloud federation, environment reviewers, script injection risks, commit-SHA pinning, dependency caching, retention, and artifact provenance.  Take each test without notes first. Then study the explanations, consult the official documentation for weak areas, and retake the test to measure improvement. The 80% setting is an editorial practice target and is not the official passing score. These are independently authored learning questions, not actual or recalled certification exam content, and this course is not endorsed by GitHub or Microsoft. No certification outcome is guaranteed.
