Wait, is the answer 'climits'? I thought that was some kind of mountain climbing gear, not a container technology. Maybe I need to lay off the caffeine before this exam...

Ah, good old cgroups. The secret sauce that ensures my containers don't turn into resource-guzzling monsters. Gotta love those control groups!

UnionFS? Really? That's more like the container filesystem, not the resource management part. I bet the answer's 'cgroups' - doesn't that sound like something that would control resource limits?

UnionFS is more about the container filesystem, not resource management. cgroups is the way to go.

Namespaces, definitely. I remember learning about that in my container training. It's the magic that keeps those pesky containers from hogging all the system resources.

Hmm, this one's got me scratching my head. Is it 'climits' or 'cqroups'? I can never keep those weird container terms straight!

No, I'm pretty sure it's 'Namespaces' that allows containers to be restricted to defined limits.

I'm not sure, but I think it might be D) cgroups because it sounds like it could be related to system resource usage limits.
