I recall something about authentication being separate from RBAC, so I don't think D is right, but I'm a bit confused about the specifics.

I practiced a similar question, and I think RBAC is more about allowing actions rather than just denying them, which makes me lean towards B as well.

I'm not entirely sure, but I feel like RBAC doesn't just deny actions; it also specifies what users can do.

I think I remember that RBAC is about defining permissions, so maybe option B is correct?

I'm not totally sure about this one. I know COPQ has different categories, but I can't remember the specifics. I'll have to think it through carefully before selecting an answer.

Hmm, I'm not too sure about this one. I know insider threats are a big problem, but 80% seems really high. I'll have to think this through a bit more.

B) Yep, that's the one. RBAC is the traffic cop of Kubernetes, directing who can go where.
