Wait, does ShadowImage really slow things down that much?

Increasing cache size (D) is always a good move!

Not sure about C, setting Copy to 15 seems risky.

I think A could work too, HDT pools are useful.

Option B sounds solid, dedicated paths can help.

Increasing the cache size on the VSP G800 might improve hit rates, but I wonder if that's a more long-term solution rather than addressing the immediate issue.

Setting Copy to 15 sounds familiar, but I can't recall if that actually reduces the impact on performance during resynchronization.

I think using dedicated FC paths for the ShadowImage target volumes could help with performance, but I need to double-check how that interacts with RAID groups.

I remember something about HDT pools managing workloads, but I'm not entirely sure if that's the best option here.

I think I've got this one. The first option about supporting batch creation/start/restart/close/wake up/sleep for virtual machines seems to be the correct description, so the incorrect one must be one of the other options.

I practiced a similar question about health plans covering dependents, and I think the answer was COBRA too, but I'm worried I could mix them up under pressure.

Okay, I've got this. Since we need to split the customer list into a test and control group, and the platform recommends a 90/10 split, stratified random sampling is definitely the way to go. I feel confident about this one.
