VMware App Volumes (VCP-AM 2019) — Question 87

A vSAN all-flash environment with these host specifications has reported high network latency, write latency, and faces degraded performance:
✑ One 1Gbps (vSAN, vMotion Traffic)
✑ One 1Gbps (Management, Fault Tolerance traffic)
Based on the specifications of each host, what is recommended to resolve the issue?

Answer options

• A. collapse all traffic into one 1Gbps NIC
• B. collapse all traffic shared under two 10Gbps NICs
• C. change stripe width to 12
• D. change MTU to 9000

Correct answer: B

Explanation

The correct solution is to collapse all traffic under two 10Gbps NICs, as this will significantly increase the available bandwidth and reduce latency. Combining traffic into a single 1Gbps NIC (option A) will exacerbate the issue by further limiting bandwidth. Changing the stripe width (option C) or adjusting the MTU (option D) does not directly address the underlying network congestion problem.
