QUESTION 41

Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for the data center Access layer, including which of the following?

 

A.

The vPC peer link is not required for Access layer control traffic, and can instead be used to span VLANs across the vPC access switches

B.

A single switch can associate per-interface with more than one vPC domain

C.

vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches

D.

Allows an EtherChannel between a server and a access switch while still maintaining the level of availability that is associated with dual-homing a server to two different access switches

 

Correct Answer: C
