Which action will remedy this problem?

An administrator has enabled vSphere Distributed Switch Health Check. The hosts connected to that
Distributed Switch all display an alert:
vSphere Distributed Switch MTU supported status
The administrator has all of the VMkernel ports MTU sizes set to 1600.
Which action will remedy this problem?

A.
Configure the Distributed Switch to MTU 9100.

B.
Disconnect and reconnect the physical network cable.

C.
Configure the physical switch to MTU 1600.

D.
Disable the Distributed Switch MTU.

Explanation:
You can increase the MTU size up to 9000 bytes. Therefore, a MTU of 9100 is not supported. The MTU
configured in the VDS must match the physical switch configured MTU.
