Wait, why would you disable cache mode? That seems counterintuitive.

Increasing the HBA queue depth sounds risky...

I practiced a similar question where changing cache modes affected performance, but I can't recall if disabling it is beneficial in this scenario.

I think increasing the number of LUNs mapped could help, but I’m not entirely sure how that interacts with the RAID group utilization.

I remember something about increasing the queue depth can help with performance, but I'm not sure if it's the external path or the server HBA that needs adjusting.

I feel like increasing the server HBA LUN queue depth to 64 is a good option, but I also have a nagging doubt about whether it’s the right choice here.

Okay, let me walk through this step-by-step. The question says the administrator needs to check the default display of the Advanced Performance pane to confirm the high ballooning activity. So the view they should choose is the one that shows memory-related metrics, which would be the Memory view.

A tiered deployment server topology sounds like it could be a good solution, but I'll need to make sure I understand how that works.

Random testing feels weird. I'm pretty sure an effective training program needs comprehensive, role-specific education that helps people actually recognize red flags.
