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
