Seriously, Kafka streams questions are the bane of my existence. Can we just skip this one and move on to something else?

This is a tricky one! I'm gonna have to go with D. 25 created, 5 active. The number of partitions determines the number of active tasks, even if we have more instances running.

I'm a bit confused here. Wouldn't the answer be B? 5 created, 5 active? Since each instance is assigned to a single partition, we should have 5 tasks total, and all of them would be active.

I'm going with C. 25 created, 25 active. If there are 5 partitions and 5 instances with 5 threads each, that's 25 tasks created and all of them should be active, right?

Hmm, I think the answer is D. 25 created, 5 active. Each partition gets its own stream task, and with 5 instances running, that's 25 total tasks created. But since there are only 5 partitions, only 5 tasks will be active at a time.

I'm going with B. If each instance has 5 threads, and there are 5 instances, that should give us 25 created and 25 active tasks, right? Wait, are we talking about Kafka or a river rafting trip? I'm getting a little stream-lined here.

Definitely D. It's all about that partition-instance distribution, you know? I wonder if the exam will have any questions about Kafka's inner workings, like how the brokers communicate with each other. That would be a real stream-liner.

Hmm, I'm not sure about this one. I'm leaning towards C, but maybe I'm missing something. I hope the exam isn't too stream-y, or I might get flushed down the toilet.

I'm not sure, but I think the correct answer is D) 25 created, 5 active because only 5 tasks can be active at a time.

I disagree, I believe it's C) 25 created, 25 active because each instance will create 5 tasks.

I think the answer is D. Since we have 5 partitions and 5 instances of the application, each instance will get one partition and have 5 stream tasks created, so a total of 25 created and 5 active.
