[All GH-200 Questions]

Which of the following scenarios would require the use of self-hosted runners instead of GitHub-hosted runners?

Show Suggested Answer Hide Answer
Suggested Answer: A, D

GitHub-hosted runners have a limit on the number of concurrent workflows (typically 20 for free-tier accounts and 5 for enterprise). If your organization needs to run more workflows simultaneously, you would need to use self-hosted runners to increase the available concurrency.

Self-hosted runners allow you to configure specialized hardware or software setups that are necessary for certain workflows. GitHub-hosted runners may not have access to custom hardware configurations like GPUs or other specialized resources, so self-hosted runners are required in such cases.

That's a tough one, I'd have to go with D. Specialized hardware is a dealbreaker for GitHub-hosted.

I practiced a question similar to this, and I think exceeding the monthly minutes is a reason too, but I’m not completely confident.

I feel like using Docker containers might also require self-hosted runners, but I can't recall the exact details.

I'm not entirely sure, but I remember something about GitHub-hosted runners having limits on concurrent workflows. Is that A?

Hmm, this is a tricky one. I'm not super familiar with the differences between the GitHub-hosted and self-hosted runners. I'll need to review the documentation to make sure I understand the specific limitations and capabilities of each. I don't want to guess and risk getting this wrong on the exam.

I've got this! The key is understanding the capabilities and limitations of the GitHub-hosted runners. Scenarios A, B, C, and D all describe situations where the GitHub-hosted runners wouldn't be sufficient, so self-hosted runners would be required. E is the only one that's a bit more ambiguous, but the others are pretty straightforward.

I think self-hosted runners are definitely needed when you have specialized hardware configurations, right? That sounds familiar.

Okay, let's think this through step-by-step. The GitHub-hosted runners have limits on concurrent workflows and monthly build time, so A and B are clear cases for self-hosted. C and D also seem like they would require more customization that the GitHub-hosted runners may not provide. E is an interesting one, I'll have to double-check the supported platforms.

Wait, can you really exceed 50,000 minutes? That seems high!

Hmm, I'm a bit unsure about this one. I know the GitHub-hosted runners have some limitations, but I'm not sure I fully understand all the differences. I'll need to review the documentation on self-hosted runners to make sure I'm clear on when to use them.

I think the key here is to identify the limitations of the GitHub-hosted runners and when self-hosted runners would be a better option. Scenarios C and D seem like they would require more specialized configurations that the GitHub-hosted runners may not support.
