I feel like old records will remain in their original partitions, but I'm not completely confident about how rebalancing works.

I practiced a similar question, and I believe that new records can end up in different partitions, especially if the key distribution changes.

I think new records go to the same partition as old ones if they have the same key, but I need to double-check that.

I remember that increasing partitions can help with load balancing, but I'm not sure if all records get rebalanced.

Okay, let me break this down step-by-step. I'll start by considering how the existing records are affected.

I'm feeling pretty confident about this one. Based on the information provided, the /var/log/syslog.log file is the most likely place to find the details we need to troubleshoot the unknown error code. That's the log I'd check first.

I'm feeling pretty confident about this one. The key is understanding how policy rule precedence works. The lower numbered rule takes priority, so the answer is B.

Wait, what? All of them? That seems a bit excessive. Maybe the exam writer is just trying to see if we're paying attention. *chuckles* I'll go with the ones that make the most logical sense.

Ah, I see what they're getting at. A is also correct, the existing records will get rebalanced across the new partitions. Guess I better brush up on my partition management skills!

Hold on, I'm pretty sure C is also correct. Increasing the number of partitions means new records might get written to a different partition, not just the old ones. Gotta be careful with these tricky questions!

Hmm, I think B and D are the correct answers. The old records will stay in their partitions, and the new records with the same key will get written to the same partition as the old ones. Simple enough, right?
