What is the default load balancing policy for a newly created VMkernel port on a vSphere Distributed Switch?

The correct answer is A. Route based on orginating virtual port ID. The default NIC teaming load balancing policy on a vSphere Distributed Switch VMkernel port is route based on originating virtual port ID.

Why each option

The default NIC teaming load balancing policy on a vSphere Distributed Switch VMkernel port is route based on originating virtual port ID.

ARoute based on orginating virtual port IDCorrect

'Route based on originating virtual port ID' is the factory default for both vSphere Standard Switches and Distributed Switches; each VM or VMkernel port is pinned to a specific uplink based on its virtual port number, distributing traffic without requiring physical switch configuration changes.

BRoute based on IP Hash

Route based on IP Hash requires EtherChannel or LACP configuration on the upstream physical switch and must be explicitly selected; it is not the default.

CRoute based on source mac address

Route based on source MAC address is an available option but is not selected by default on a newly created port group.

DRoute based on physical NIC load

Route based on physical NIC load is a dynamic load balancing policy available only on vDS and must be manually configured; it is not the default.
