Which policy is used for intelligent optimization of network interface traffic on a vSphere Distributed Switch (VDS)?
A. Route Based on IP Hash
B. Route Based on Source MAC Hash
C. Route Based on Physical NIC Load
D. Route Based on Originating Virtual Port
There all load balancing functions, explicit failover is the only non-load balance option. I think the key here is Route Based on Physical NIC load is only available for Distributed Port/ Distributed PortGroups.
Route Based on IP/MAC Hash and Route Based on Virtual Port are simple distribution functions. None of them take the load of the links into consideration. The Physical NIC Load function is the only option that applies intelligence.
