A GitHub Enterprise administrator runs the platform an organisation's developers build on: who can sign in, what each person can reach, which automation is allowed to run and how code stays secure. Microsoft certifies this job through its GitHub Administration credential, an intermediate exam aimed at administrators, DevOps engineers and technology managers.
The credential is examined as GH-100: 100 minutes, 65 questions and a scaled score of 700 out of 1000 to pass. Sitting it in the United States costs US$99 as of September 2026; Microsoft sets the fee by the country where the exam is proctored, so check the price at checkout. Before you book, the free GitHub Administration sample questions show the scenario style you will face, and the rest of this guide explains the job, the five skill areas and a six-week plan to get ready.

What does a GitHub Enterprise administrator actually do?
Most of the work is governance at scale. A developer who owns one repository decides its branch protection and its collaborators. An enterprise administrator decides those things for hundreds of organisations and thousands of repositories at once, through policies that individual owners cannot quietly override. The job exists because a setting that is harmless in one repository becomes a risk when it is repeated across an entire company.
