Which two statements are true about network traffic shaping? (Choose two.)

A.
The settings affect only traffic being sent out the uplink adapter to the physical
network.

B.
The settings affect all vSwitch traffic.

C.
The settings are defined on a per port group basis.

D.
The settings affect only traffic coming into the uplink adapter from the physical
network.

E.
The settings are defined on a per-virtual machine basis.

Explanation:
"defined on a per port group basis. " could be considered a correct answer because
according to the VMWare Infrastructure 3:Install and Configure guide, "Traffic shaping
may be defined at the virtual switch OR Port Group level. " The important distinction
here is that they can be defined at this level, but they are APPLIED on a per-virtual
machine basis or more directly, to the VM’s virtual NIC’s.
