Surprised to see that disk group congestion isn't more commonly mentioned!

I disagree, I think B could be a factor too. Encryption adds overhead.

D could also be a problem if the sizing is off. Always check that first!

I thought vSAN encryption could add some overhead, but I'm not convinced it's the main issue here. Option B seems less likely to me.

I practiced a similar question where disk sizing was a factor, so I'm leaning towards option D as a possible root cause.

I'm not entirely sure, but I feel like disk group congestion could definitely lead to increased latency. Maybe option E?
