I practiced a similar question last week, and I think D is definitely one of the answers. A sounds familiar too, but I can't recall the details.

I remember something about ZooKeeper helping with partition management, so A seems right to me. But I’m a bit confused about the second choice.

I think Kafka uses ZooKeeper for leader election, so I might go with D. Not sure about the other option though.
