The Cisco Nexus 1000V in the VMware vSphere solution effectively creates an additional access layer in the virtualized data center network; which of the following
1000V characteristics can the designer take advantage of?

A.
Offloads the STP requirement from the external Access layer switches

B.
If upstream access switches do not support vPC or VSS the dual-homed ESX host traffic can still be distributed using virtual port channel host mode using
subgroups automatically discovered through CDP

C.
Allows transit traffic to be forwarded through the ESX host between VMNICs

D.
Can be divided into multiple virtual device contexts for service integration, enhanced security, administrative boundaries, and flexibility of deployment

Explanation:
“Virtual Port Channel Host Mode Virtual Port Channel Host Mode (vPC-HM), shown in Figure 5-33 , allows a port channel from the Cisco Nexus 1000V to be
terminated on two separate upstream switches, even if these switches do not support a clustering technology, such as vPC or VSS.”
