Hmm, this question is a real brain-teaser. I wonder if the exam committee has hidden a joke answer in there somewhere, like 'Maintain a healthy work-life balance for the storage engineers'.

C seems a bit out of place here. Failover for protocol threads is more of a reliability concern, not a performance one. I'd focus on A, B, and D.

I think D is also important, the prefetch algorithm can have a big impact on overall performance. Gotta keep those cache hits high!
