VMware App Volumes Specialist (2021) — Question 53

An administrator is troubleshooting vSAN performance issues, and the performance diagnostics reports:

"There are errors seen in one or more physical NICs on one or more hosts."

Which two problems must be resolved to fix this issue? (Choose two.)

Answer options

• A. A 25 Gb/s NIC needs to be installed.
• B. There are incompatible firmware and driver versions.
• C. There is an incorrectly set MTU.
• D. The vSAN version needs to be upgraded to 7.0.
• E. A firewall is blocking ports.

Correct answer: B, C

Explanation

The correct answers are B and C because incompatible firmware and driver versions can cause communication issues, while an incorrectly set MTU can lead to packet loss or fragmentation, affecting performance. The other options do not directly address the NIC errors reported in the diagnostics.
