GitHub Administration (GH-100) Practice Test

This certification is designed for system administrators, DevOps engineers, application administrators, IT professionals, and technology managers with intermediate-level experience in GitHub Enterprise Administration. Ideal candidates are those who manage GitHub Enterprise environments on a day-to-day basis, configure organizational policies and security settings, support developer workflows, and ensure compliance within their organizations.

Professionals working in roles such as GitHub Enterprise administrator, platform engineer, DevOps engineer, or cloud infrastructure manager will find this certification most relevant. It is suited for those who have hands-on experience with GitHub's enterprise features but want a formal credential to validate their expertise and advance into senior administration or architecture roles.

There are no formal prerequisites required to sit for the GH-100 exam. However, Microsoft and GitHub recommend intermediate-level experience with GitHub Enterprise Administration before attempting the exam. Candidates should be comfortable navigating GitHub Enterprise Cloud and/or GitHub Enterprise Server, configuring organization and enterprise-level settings, and managing user access.

Practical familiarity with identity providers (such as Azure AD or Okta), SAML SSO, SCIM protocols, GitHub Actions runner management, and security features like Dependabot and code scanning is strongly recommended. Candidates who have previously earned the GitHub Foundations certification or have equivalent hands-on experience will be well-positioned to succeed.

The GH-100 exam is administered through Pearson VUE and must be taken under proctored conditions. Candidates have 100 minutes to complete the assessment. The exam may include interactive components in addition to traditional question types. The passing score is 700 out of 1000. The exam is currently offered in English only.

The exam is scored across seven domains with defined percentage weights. If a candidate fails, they may retake the exam 24 hours after the first attempt; subsequent retake waiting periods vary per Microsoft's retake policy. An official practice assessment is available on Microsoft Learn to help candidates familiarize themselves with the question style, wording, and difficulty level. An exam sandbox (GHCertDemo.starttest.com) is also available to experience the exam interface before test day.

• 1.Domain 1: Support GitHub Enterprise for users and key stakeholders (9%) — Covers distinguishing administrator-resolvable issues from GitHub Support tickets, generating support bundles and diagnostics, recommending developer workflow standards (branching, code review, CI/CD strategy), using GitHub APIs to extend admin capabilities, and evaluating GitHub Marketplace apps and actions.
• 2.Domain 2: Manage user identities and GitHub authentication (11%) — Covers enabling and enforcing SAML SSO for single and multiple organizations, requiring two-factor authentication, selecting and configuring identity providers, understanding SCIM provisioning with Azure AD and Okta, and contrasting team synchronization with SCIM.
• 3.Domain 3: Describe how GitHub is deployed, distributed, and licensed (9%) — Covers contrasting GitHub Enterprise Cloud, GitHub Enterprise Server, and GitHub AE capabilities; describing billing models for seat licenses, GitHub Actions minutes, and GitHub Packages storage; and locating license usage statistics.
• 4.Domain 4: Manage access and permissions based on membership (18%) — Covers defining GitHub organizations and teams, contrasting single vs. multiple organization deployments, describing role-based permissions (organization members, owners, billing managers, outside collaborators), applying least-privilege principles, and configuring enterprise and organization policies.
• 5.Domain 5: Enable secure software development and ensure compliance (36%) — Covers GitHub's security posture support, scrubbing sensitive data from repositories, audit log APIs (REST and GraphQL), security policies, dependency vulnerability management with Dependabot, CodeQL-based automated code scanning, secret scanning, security advisories, supported access tokens, GitHub Apps vs. OAuth Apps, and enterprise managed users (EMUs).
• 6.Domain 6: Manage GitHub Actions (16%) — Covers distributing reusable actions and workflow templates across the enterprise, configuring organizational use policies for Actions, managing GitHub-hosted and self-hosted runners (including IP allow lists, proxies, labels, and groups), monitoring and troubleshooting runners, and managing encrypted secrets at repository and organization levels.
• 7.Domain 7: Manage GitHub Packages (5%) — Covers supported package registries, accessing and sharing packages, integrating GitHub Packages into workflows with GitHub Actions or other CI/CD tools, and differentiating GitHub Packages from releases.

• Start with the official GH-100 Study Guide on Microsoft Learn (aka.ms/GH100-StudyGuide), which maps every exam domain with specific sub-topics and bullet points — use it as a checklist to track your preparation progress.
• Take the free official Practice Assessment on Microsoft Learn before scheduling your exam; it mirrors the actual question style and difficulty, and helps identify knowledge gaps across all seven domains.
• Use the GitHub Certification exam sandbox at GHCertDemo.starttest.com to get comfortable with the interactive question types before exam day, since the GH-100 may include lab-style components beyond standard multiple-choice.
• Build hands-on experience in a GitHub Enterprise trial environment: practice configuring SAML SSO with a test identity provider, setting up SCIM, creating self-hosted runners, and enabling Dependabot and code scanning on real repositories.
• Pay special attention to Domain 5 (Enable secure software development and ensure compliance), which carries the highest weight at 36%. Focus on the differences between GitHub Apps, OAuth Apps, and PATs; the audit log REST and GraphQL APIs; and the full Dependabot/CodeQL/secret scanning feature set.
• Review the official GitHub Docs for GitHub Enterprise Cloud and GitHub Enterprise Server side-by-side to understand feature parity differences — exam questions frequently test your ability to distinguish GHEC, GHES, and GHAE capabilities.
• Study the GitHub Actions runner management documentation thoroughly, including the security implications of self-hosted runners on public repositories, IP allow list configurations, and runner group access controls, as Domain 6 accounts for 16% of the exam.

The GitHub Administration certification is directly applicable to roles such as GitHub Enterprise Administrator, Platform Engineer, DevOps Engineer, Site Reliability Engineer, and Technology Manager. As GitHub Enterprise adoption grows across regulated industries and large enterprises, professionals who can manage secure, compliant, and scalable GitHub environments are in high demand. The certification signals readiness to own enterprise-wide GitHub strategy, including identity federation, policy governance, and CI/CD infrastructure.

According to the 2025 Pearson VUE Value of IT Certification report, 32% of certified professionals received salary increases after earning a certification, and 82% gained confidence to pursue new career opportunities. GitHub administrators in the United States can expect competitive compensation in the range of $120,000–$180,000 USD annually, varying by seniority, geographic location, and the complexity of the environments they manage. Compared to general DevOps certifications, the GH-100 is highly specific to GitHub's ecosystem, making it a strong differentiator for professionals in organizations standardized on GitHub Enterprise.
