The Microsoft GH-100 exam validates your ability to administer GitHub at the enterprise level. This certification, part of the Microsoft GitHub Certifications path, is designed for IT professionals and system administrators who manage GitHub deployments, user access, and security policies. This landing page guides you through the exam structure, core topics, and practical preparation strategies to help you succeed. Whether you're new to GitHub administration or refining your expertise, understanding the exam scope and question formats is essential for confident test day performance.
Use this topic map to guide your study for Microsoft GH-100 (GitHub Administration) within the Microsoft GitHub Certifications path.
The GH-100 exam uses multiple question types to assess both conceptual knowledge and practical decision-making in real-world GitHub administration scenarios.
Questions increase in complexity and emphasize practical application, reflecting the skills you'll use when managing GitHub in production environments.
Effective preparation combines structured study of each topic with hands-on practice and regular self-assessment. A focused routine over 4-6 weeks allows you to build confidence and identify weak areas before exam day.

Access and permissions management, user authentication, and security compliance typically represent the largest portion of the exam. These topics directly impact how organizations protect code and manage team workflows. However, all seven domains are tested, so balanced preparation across all topics is important.
Authentication establishes who users are, access control determines what they can do, and security policies enforce how they do it. For example, you might configure SSO for authentication, set repository permissions for access control, and enable branch protection rules to ensure code review before merging. Understanding these three layers as an integrated system helps you design secure, scalable GitHub environments.
Practical experience significantly helps, especially with configuring users, managing teams, and setting permissions. If you have limited hands-on access, focus practice questions on scenario-based items and use the simulation questions to build familiarity with the admin interface. Even without a live environment, studying real-world configuration examples and workflows will improve your readiness.
Common errors include confusing permission levels (e.g., triage vs. maintain), misunderstanding the scope of policies (organization-wide vs. repository-specific), and overlooking authentication method implications for compliance. Carefully read scenario questions to identify the organizational context and constraints before choosing an answer.
In your final week, take a full-length timed practice test to identify remaining gaps, then drill those specific topics using Q&A sets. Review explanations for any incorrect answers and create a quick reference guide for terminology and configuration steps. Avoid cramming new material; instead, reinforce concepts you've already studied and build test-taking confidence through practice.
Which of the following are valid ways to pass data to a reusable workflow in a separate repository?
You declare namedinputs in the reusable workflow's on.workflow_call block and then pass values from the caller using thewithkeyword, allowing the called workflow to consume those parameters.
You define required secrets in the caller repository and supply them to the reusable workflow via thesecretskeyword in the workflow-call step, ensuring sensitive values are securely passed.
What is the new capability of GitHub's billing dashboard?
The revamped Billing&Licensing dashboard now includes a dedicated''Copilot'' tab that shows per-user seat assignments, usage counts, and estimated costs for your organization's GitHub Copilot licenses, enabling you to track Copilot consumption by individual users.
You are managing a repository in your organization's GitHub account. A team member asks you to confirm who has access to the repository and their permission levels. Which tool should you use to review and manage repository access?
Use theRepositorySettingsManageAccess page to view all users and teams with access and their assigned permission levels.
How does Dependabot determine which security update PRs to open?
Dependabot relies on your repository's enabled Dependency Graph and Dependabot Alerts to identify vulnerable dependencies; it then automatically opens pull requests to update to the patched versions that resolve those alerts.
What distinguishes Enterprise Managed Users (EMUs) from standard GitHub accounts?
EMU accounts are provisioned and authenticated exclusively through your identity provider - users sign in via the IdP and cannot use or manage GitHub-native credentials.
