C) Network Isolation and Eliminate SPOF? Sounds like a recipe for a really boring and isolated network. Where's the fun in that?

Hmm, this is a tricky one. I'm debating between B) and D). I know RAID storage can help with fault tolerance, but I'm not sure if that's a "key requirement." I think I'll go with B) to be safe.

I remember discussing fault tolerance in class. I think the key is to isolate faults and eliminate any single points of failure. So I'll go with B) Fault Isolation and Eliminate SPOF.

Okay, let me break this down. I'm pretty sure we need to eliminate any single points of failure (SPOF), so that narrows it down to B) and C). Fault isolation also seems important for fault tolerance, so I'm leaning towards B).
