Question 72

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.)

    Correct Answer: B, C

    If there are errors seen in one or more physical NICs on one or more hosts, two likely problems must be resolved: incompatible firmware and driver versions, and improperly set Maximum Transmission Unit (MTU). Incompatible firmware and driver versions can cause communication issues and errors on the network interface cards (NICs). An incorrectly set MTU can lead to fragmentation and packet loss, which can adversely impact network performance and cause errors. Installing a new 25 Gb/s NIC is not a precise solution, upgrading the vSAN version may not address NIC-specific errors, and firewall blockage typically affects connectivity rather than NIC errors.
