Not sure about using gVisor for all workloads, though.

I feel like I need to double-check how to reference the gVisor runtime in the pod spec; it seems tricky!

I believe the command to create the pod should include the runtime class name, but I might be mixing it up with another resource type.

I remember practicing a similar question about creating a pod with a specific runtime class, but I can't recall the exact command for specifying the runtime.

I think we need to define the RuntimeClass first, but I'm not entirely sure about the exact syntax for that.

Okay, I've got an idea. Since we need to block remote printer access but allow it internally, the Extended ACL option sounds like it could work. That should let us create different rules based on the user's location.

Hmm, I'm not totally sure about this one. I think it might be B, where you can set the order of the sections numerically, but I'm not 100% confident.

I practiced a question like this, and I believe XMPP was the right protocol for inter-cluster communication. Seems to fit here too.
