I thought it would be more than 5 active with 5 instances.

Wait, how can there be 25 tasks? That seems off.

I thought that if there are 5 partitions and 5 threads, it would mean 25 tasks in total. But I’m not sure if all of them would be active at the same time.

I practiced a similar question, and I think each instance can handle one task per partition, so maybe 5 active? That feels right, but I’m a bit confused.

I remember that the number of stream tasks is based on the number of partitions, so I think there will be 5 created. But I'm not sure about how many will be active with 5 instances running.

I feel like the answer is D, 25 created and 5 active, because the threads multiply, but only one thread can work on each partition at a time.

Ah, I remember learning about this in class. The xinetd config files are stored in a specific directory, so I just need to recall the full path.

I feel pretty confident about the parent-child component event handling, but the other options are making me second-guess myself. I'll need to carefully review each choice.
