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

Explanation:
A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus™ 5000 Series devices to appear as a single PortChannel to a

third device. The third device can be a Cisco Nexus 2000 Series Fabric Extender or a switch, server, or any other networking device.
