I’m a bit confused; I thought cgroups were just for monitoring, not limiting access.

This question seems straightforward. I think the key is understanding the importance of separating test definition from test execution in a TAA.

I remember practicing a similar question in class; I think it was about what tags display, but I can't recall the specifics now.
