D is interesting, but not sure if it's necessary for this setup.

C seems off, NL-SAS won't cut it for low latency needs.

Wait, are we sure FMD drives can handle that latency?

Definitely agree with B, FMD drives are solid for this.

I think option B is the best choice for low latency.

I vaguely remember that NL-SAS drives are generally slower, so I doubt option C would meet the latency requirement.

I feel like the HDP pool with FMD drives might be the right answer since it focuses on performance, but I’m a bit uncertain about the latency requirements.

I think I practiced a similar question where HDT pools were recommended for consistent access, but I can't recall the specifics.

I remember that for low latency, FMD drives are usually a good choice, but I'm not sure if an HDP pool is the best option here.

I've got this! The PRIMARY KEY is on ORDER_ID, and the UNIQUE constraint is on SERIAL_NO. Those are the two columns that will have indexes created automatically. I'm feeling good about this one.

This seems like a pretty straightforward question. I'd focus on looking at the total IOPS and the array group utilization to see if the pool is configured appropriately.

I'm a bit unsure about this one. The question mentions a "unique solution" for each question, so I'm not sure if the Call Quality Dashboard is the only way to get the packet loss data. I'll need to double-check the other options.
