I'm torn between B and E. Both seem like they could be correct.

I disagree, I believe the answer is E. It mentions using Persistent Memory and RDMA before flushing to Flash and disk.

I think the answer is B. It makes sense to use Persistent Memory and RDMA to reduce redo log write latency.

You know, I'm just going to guess. This seems like the kind of question where if you don't have the specific technical knowledge, it's just a shot in the dark. I'll go with C, just for the heck of it.

Ah, I see what they're getting at. This is all about optimizing database performance, right? In that case, I'd go with E as well. It's the most comprehensive answer.

I'm not sure about this question. It seems a bit too technical for my liking. I'm more of a big-picture kind of guy.
