Not sure about the Step Metrics tab, seems a bit complicated for a quick check.

Data partitioning is key for performance, don’t skip that step!

Wait, are there really 'Out Of Memory' errors? That sounds serious!

Definitely check the memory on the server first.

I feel like data partitioning from option C could help, but I’m not clear on how to implement it effectively.

Option D sounds familiar; I think we practiced comparing input and output buffers in our last session.

I’m not entirely sure about the performance gathering parameter in option A. Did we cover that in detail?

I remember we talked about checking memory issues, so option B seems like a good starting point.

This question sounds familiar! I practiced one about identifying customer requirements, and I almost picked Target Quality Assurance.

Hmm, I'm a bit unsure about this one. The question is asking about a specific MAC address and IP address, so I'll need to make sure I understand how to configure DHCP to handle that scenario.
