Question 7/60

A VI Admin is analyzing a performance degradation event for a massive database running on a 6- node vSAN ESA cluster.
Using the vSAN Performance Service, the admin charts the latency across the three distinct vSAN execution layers for the specific VMDK:
```
[vSAN Performance View - VMDK Layer Breakdown]
Component Latency
Virtual Machine (Guest) 22.4 ms
DOM Client (ESX-01) 22.0 ms
vSAN Network 19.5 ms
DOM Owner (ESX-04) 1.2 ms
LSOM (ESX-04) 0.9 ms
```
Based on the "Top-Down" methodology and this data matrix, which of the following statements correctly isolate the bottleneck? (Select all that apply.)

A. The backend physical storage (LSOM on ESX-04) is highly responsive (0.9 ms) and is NOT the cause of the performance issue.

B. The high latency is artificially created by Deduplication hash table lookups occurring at the DOM Client layer.

C. The vSAN Network between ESX-01 and ESX-04 is dropping packets or experiencing switch buffer overflows, as indicated by the 19.5 ms network latency jump.

D. The Virtual Machine is running smoothly because the Guest latency (22.4 ms) closely matches the DOM Client latency (22.0 ms), indicating no vCPU ready-time issues inside the guest.

E. The DOM Owner on ESX-04 is suffering from CPU saturation, causing the 1.2 ms delay before sending data to the LSOM.
