Partition rebalancing, huh? Sounds like my high school gym class. Always gotta be switching teams and rearranging the lineups.

Wait, so increasing partitions doesn't automatically rebalance the group? Kafka, you're full of surprises! Better memorize these three triggers for the exam.

I agree with that. And when a consumer in a consumer group shuts down, it will also trigger partition rebalance.

Aha! I knew those were the right answers. Partition rebalancing is such a key part of Kafka consumer group management. Can't believe anyone would think adding a broker would trigger it.

Ha! I almost picked C, but then I remembered that adding a new consumer doesn't necessarily mean the partitions will be rebalanced. Gotta think this one through carefully.

Hmm, I think B, D, and E are the correct answers. Increasing partitions and adding a consumer should trigger a rebalance, and removing a broker or a consumer dropping out would definitely do it too.
