Hold up, is this a trick question? If two out of three replicas are down, the answer has to be C. Waiting is the only way to go!

Option B is the way to go. Why wait when you can just take what you can get? Carpe diem, am I right?

Hmm, this is a tricky one. I'm leaning towards A - if you can't get the minimum replicas, you should just get an exception.

I agree with Janna, C) makes sense because the min.insync.replicas is set to 2.

I'm going with B. If the broker can't get the minimum number of replicas, it should just accept the request with what it has.

Option C makes the most sense to me. If you can't get the minimum number of in-sync replicas, the request should just wait until it can.
