Which two characteristics of the underlying physical network does VMware NSX require for
robust IP transport? (Choose two.)

A.
QoS classification and marking is required to provide end-to-end flow control.

B.
The physical network should provide scalable network I/O using Layer 2 Multipathing
(L2MP) and Multichassis Link Aggregation (MLAG).

C.
The physical network should provide scalable network I/O using Equal Cost Multipathing
(ECMP).

D.
QoS is not necessary since classification and marking will be done in the overlay.
