With this configuration, a single in-sync replica becomes read-only. Produce request will receive NotEnoughReplicasException.

C is interesting, but I don't think it blocks like that.

B seems off, acks=all needs more replicas.

Wait, is it really that strict? Sounds harsh!

Totally agree with A, can't have enough replicas!

A is correct, NotEnoughReplicasException will be returned.

I'm pretty certain that if two replicas are unavailable, we can't satisfy the min.insync.replicas requirement, so it should return an exception.

I feel like the request would still go through with just one in-sync replica, but that doesn't seem right with acks=all.

I remember practicing a similar question, and I believe the produce request would block until one of the replicas is back online.

I think if two replicas are down, we might get a NotEnoughReplicasException, but I'm not entirely sure.

I'm not totally sure about this one. The options seem a bit confusing to me.

This looks like a straightforward multiple-choice question. I'll carefully read through the options and the provided information to determine the correct answer.

Okay, let's see. Scoping to the image names makes sense, as that would target the specific containers we want. Namespaces could work too, but that might be too broad. I'll go with option A.

Hmm, I'm a bit confused by this question. There are a few different options presented, and I'm not sure which one would be the most appropriate. I'll need to think through the implications of each approach carefully.
