Validates knowledge of managing GitHub Enterprise identities and access, environment setup, secure development, Actions governance and usage monitoring.
GH-100 is closed book: 100 minutes for 60 scored multiple-choice questions plus about 10 to 15 pretest items. Scenarios cover running GitHub Enterprise: account models, SSO and SCIM, security policies and governing Actions. Microsoft rewrote the objectives in July 2026. We compared the main options on question style, current objectives and price.
Start with Microsoft's free practice assessment, then add MeasureUp or a Udemy set for volume, keeping in mind that most third-party sets were written for the earlier outline.
| Practice test | Best for | Questions | Price |
|---|---|---|---|
 GitHub Administration practice test | Free doc-linked questions | 97 | Free |
 GH-100 GitHub Administration Practice Test | Explained question bank | 105 | $99 |
 GitHub Administration Certification GH-100 [Exams 2026] | Volume for drilling | 300 | $40 |
Microsoft's own practice questions, which show the style, wording and difficulty of the real exam and let you review explanations afterwards. A good baseline, though small on its own.
Great fit if you want a free official baseline before spending anything, and a readiness check near the end.
Poor fit if you need a large bank to drill; candidates who passed paired it with MeasureUp.
Community-written questions kept in an open GitHub repository, each linking to the GitHub Docs page behind the answer. Actively maintained through 2026, with timed challenge modes.
Great fit if you want extra free questions and a docs link to read for every miss.
Poor fit if you want written explanations or a full-length timed exam; use MeasureUp.
Questions with explanations, in a certification mode that mimics the exam and a practice mode where you choose topics. Written in November 2025 for the earlier seven-domain outline, and a free demo is available.
Great fit if you want a large explained question set and a candidate-tested route: a passing candidate used it after the Microsoft assessment.
Poor fit if you need questions written for the July 2026 outline; pair it with the Microsoft assessment and the docs.
Six 50-question exams with an explanation for each response, taken by more than 4,000 learners. Last updated in January 2026, before the objectives were rewritten.
Great fit if you want volume for repeated drills at a low price and will cross-check against the new objectives.
Poor fit if you want questions on the July 2026 outline; start with the Microsoft assessment.

Yes. Microsoft says the exam changed significantly in July 2026, with objectives added, removed and reworded. Most paid practice sets were written for the earlier outline, so use them for volume and check any surprises against the docs.
Candidates who passed say not by itself. One used the Microsoft assessment first, then MeasureUp, before taking the exam.
You have 100 minutes. Microsoft does not publish the number of questions, and a score of 700 or more is needed to pass.
