D and E make sense too. Congested disks can slow down performance significantly.

I lean towards B and D. Encryption adds overhead, and sizing is crucial.
MI

Agreed, C is a big one. Packet loss can mess everything up.
NA
Naomi

I think C and E are likely causes. Network issues can really spike latency.
CE

A could be a factor too. IP hash can complicate things if not set right.

D seems unlikely, if the disks are sized correctly, right?
EL

I think B might be a factor too, but not sure it's a root cause.
LY
Lynelle

Definitely C and E, network issues can really slow things down.
CH
Chaya

Surprised that disk group congestion isn't more commonly mentioned!
JO
Jolanda

Agreed, C and E seem spot on for this kind of problem.
LU

I think B could also be a factor, but not sure.
EL
Elouise

Definitely C and E, those are common issues.
JE
Jessenia

I’m a bit confused about A; I thought the teaming policy shouldn’t affect latency that much, but it might be worth considering.
NA
Nana
6 months ago
I practiced a similar question, and I think E could definitely be a factor if there’s congestion in the disk groups.
JA
Javier

I’m not entirely sure, but I feel like D might be relevant if the disk groups aren’t sized correctly.
KA
Karina
7 months ago
I remember something about network issues causing latency, so I think C could be a root cause.
LA
Laurel
7 months ago
I recall that the teaming policy in A could affect performance, but I don't think it's as likely as the disk group issues.
YO
Yolande
7 months ago
I think B regarding vSAN encryption could potentially add some latency, but I'm not confident it's a primary cause.
KR
Krissy
7 months ago
I'm not entirely sure, but I feel like E about disk group congestion might also be a factor. We practiced a similar question on that.
JA
Jade

I remember discussing how network issues can really impact latency, so I think C about packet losses could be a root cause.
