An administrator is building a new vSphere Standard Switch with two active uplinks. The physical
switch ports for these uplinks are placed in an etherchannel.
Which load balancing policy should the administrator use to support the etherchannel
configuration?
A.
Route based on IP hash
B.
Route based on the originating virtual port
C.
Route based on source MAC hash
D.
Route based on physical NIC load
Explanation:
A is correct
Route based on IP Hash load balancing requires that the physical switch ports be combined into an EtherChannel (sometimes called an aggregation bond, port-channel, or trunk).

A is Correct.
Supported Virtual Switch NIC Teaming mode: IP HASH
Note: The ONLY load balancing option for vSwitches or vDistributed Switches that can be used with EtherChannel is IP HASH:
Do NOT use beacon probing with IP HASH load balancing.
Do NOT configure standby or unused uplinks with IP HASH load balancing.
VMware supports ONLY ONE EtherChannel per vSwitch or vNetwork Distributed Switch (vDS).
So you must create another vSwitch or vDS if you need an extra Etherchannel!
A : Route based on IP hash
