Which two characteristics of the underlying physical network does VMware NSX require for robust
IP transport? (Choose two.)
A.
The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP)
and Multichassis Link Aggregation (MLAG).
B.
The physical network should provide scalable network I/O using Equal Cost Multipathing
(ECMP).
C.
QoS is not necessary since classification and marking will be done in the overlay.
D.
QoS classification and marking is required to provide end-to-end flow control.
Agreed B,D

A key benefit of NSX’s network virtualization functionality is virtual-to-physical
network abstraction and decoupling. For successful NSX deployment, it is
important that the physical fabric provides robust IP transport with the following
attributes:
• High-bandwidth & fault-tolerance
• Jumbo MTU
• Quality of Service (QoS)

Additionally, the NSX Edge provides an ideal centralized
point for seamless integration with the physical network infrastructure to handle
communication with the external network (i.e., north-south communication) with
ECMP-based routing.
