I don't think removing system:anonymous is enough, we need more layers.

I definitely remember cleaning up the ClusterRoleBinding for system:anonymous, but I might need to double-check the command syntax.

The admission controller NodeRestriction is crucial here, right? I hope I can recall the exact steps to apply it during the exam.

I think we need to edit the kube-apiserver manifest to include the Node and RBAC modes, but I might be mixing it up with another question we did.

I remember we practiced configuring the API server with RBAC, but I'm not entirely sure how to set the authorization modes correctly.

Hmm, I'm a little unsure about this one. The question mentions several different Gas-related terms, and I want to make sure I understand the differences between them before answering. I might need to review my notes on Gas again.

Okay, I've got this. The question is asking about the capabilities of the production floor execution interface, so I'll select the options that seem to match those capabilities.
