GH-200-Specific Tips
- Focus heavily on workflow syntax and YAML structure—this is the foundation for 40% of exam content. Practice writing workflows from scratch.
- Build at least 3-5 custom actions (JavaScript and composite types) hands-on. Reading docs is insufficient; implementation cements understanding of action inputs, outputs, and metadata.
- Test self-hosted runner setup in a lab environment. Understand networking, authentication, and scaling considerations—this is a distinct domain often overlooked in study.
- Deep-dive into GitHub Actions security: secrets management, OIDC tokens, permissions scoping, and supply chain risks. Security is a cross-cutting domain worth 1/8 of the exam.
- Study workflow commands (set-output, set-env, add-path) and environment variable scope (runner, job, step, and action levels). These appear across multiple domains.
- Practice enterprise scenarios: managing actions across organizations, runners at scale, and audit requirements. The enterprise domain adds complexity worth dedicated practice.
- Review the GitHub Actions documentation's workflow syntax reference and best practices guide twice during your study period—the exam tests practical knowledge, not memorization.
