Option B seems like the logical answer here. The newer client should be able to talk to the newer broker, but the older client just wouldn't be able to communicate with the newer broker. Kafka is all about keeping things compatible, you know?

I'm going with option C too. It just makes sense that the newer client can talk to the newer broker, and the older client can also communicate with the newer broker. Anything else would be just too restrictive, in my opinion.

Hmm, I think option C is the correct answer. The newer client should be able to talk to the newer broker, and the older client should be able to talk to the newer broker as well. That's my understanding of the Kafka versioning compatibility.

All this version compatibility talk is making my head spin. I just hope I don't end up like a bad broker - unable to communicate with anyone!

No, actually a newer client can talk to a newer broker, and an older client can talk to a newer broker.

Don't worry, as long as you keep your clients and brokers updated, you'll be fine.

Hah, I bet the answer is option D just to trick us. A newer client can't talk to a newer broker, but an older client can? That's just silly!

Option B sounds more plausible to me. A newer client can communicate with a newer broker, but an older client may not be able to talk to a newer broker. Backward compatibility is not always guaranteed.

I think option C is the correct answer. Newer clients should be able to talk to newer brokers, and older clients should also be able to talk to newer brokers. The versions should be compatible.
