D seems too strict. Not all apps need that level of security.

D) The default namespace enforces the strictest security policies by default. Gotta keep those pods in line!

C) Each namespace can have only one active policy. That's a bummer, I was hoping for more flexibility.

Namespaces are like little containers for my Kubernetes apps. I need to keep those security policies straight!

I thought namespaces were more about organization and that Pod Security Admission policies apply cluster-wide, so A could also be a possibility.

I practiced a question similar to this, and I think it mentioned that each namespace can only have one active policy, which makes me lean towards C.

I'm a bit unsure, but I feel like there was something about the default namespace having stricter policies. Could that be D?

Okay, I think I understand now. Namespaces allow you to apply different policies to specific areas, so B is the best answer.

The default namespace enforcing the strictest policies sounds like it could be the right answer, but I'm not 100% sure. I'll double-check the other options.
