An ESXi host is limited to two 1GbE physical NICs to support VM traffic.
Which VDS teaming policy should be chosen to ensure maximum availability across both uplinks?
A. Route Based on IP Hash
B. Route Based on Originating Virtual Port
C. Route Based on Physical NIC Load
D. Route Based on Source MAC
Correct answer is C
Route based on physical NIC load. Based on the current load of the physical network adapters connected to the port. If an uplink remains busy at 75% or higher for 30 seconds, the host proxy switch moves a part of the virtual machine traffic to a physical adapter that has free capacity.
This is the only one in the list of policies that will try to load balance equally across both NICs.
Should be ‘B’.

A, VDS “teaming policy”. Route Based on IP hash is a requirement for EtherChannels configured on physical switch.
