An administrator is creating a vNetwork Standard Switch with virtual machine and VMkernel networking. The administrator has two uplinks attached to the switch but wants to separate the virtual machine and VMKernel traffic to the two uplinks.
Which load-balancing policy will guarantee this requirement is met, even if additional management or virtual machine traffic is added to the switch?
A.
Route based on IP hash
B.
Router based on source MAC hash
C.
Route based on the originating port ID
D.
Use explicit failover

I don´t understand why the correct answer is the D.
If use D option, all traffic may be routed to the same uplink …..
I guess the reason for D is that for the specific vmkernel or virtual machine network you can choose to override the switch failover priority and put one uplink as active and the other uplink as standby or unused.
In that way the explicit failover order option will ONLY use the active uplink port.
Any of the other routing options can potentially use either uplink to load balance unless explicitly excluded.
