So if they have the same label, they match, right?

I think it’s more about the pods being there first.

Wait, does the namespace really matter?

Yes, label selectors match based on labels, not pod status.

I’m a bit confused about the readiness and liveness probes. Do they really affect whether the selector matches? I’m not sure about option A.

I practiced a similar question, and I think the key is that both pods need to exist when the selector is declared, which makes me consider option D.

I remember something about namespaces being important, but I’m not sure if that applies here. Maybe option C?

I think the label selector will match both pods regardless of their state, so I’m leaning towards option A.

Hmm, I'm not too sure about this one. I'll need to think it through a bit more. Maybe I should review the material on row-level security in Analytics.

Hmm, I'm a bit unsure about this one. I know queues, semaphores, and notifiers are all used for inter-process communication, but I can't remember if local variables fall into that category.
