Prepare for the GH-100 exam (GitHub Administration). In this lesson: GitHub-hosted, larger, and self-hosted runners, runner groups for organizations, repositories, and workflows, IP allow lists and static IP addresses, Azure private networking for hosted runners, Actions usage and performance metrics, and troubleshooting self-hosted runners. Includes three original practice questions.

- Contoso’s Actions metrics show the average queue time of the firmware workflow rising to forty minutes, while its average run time stays the same. What’s the likely cause?
