D. VSS
Which technology combines two Nexus switches to form a single logical switch, while maintaining control plane separation between the two devices, and requiring independent management of each device?
vPC maintains 2 control planes.
VSS maintain one control plane for both devices
Answer should be A. vPC
What is vPC
vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a PortChannel across multiple switches (i.e vPC peers).
vPC is similar to Virtual Switch System (VSS) on the Catalysts 6500s. However the key difference between vPC and VSS is that VSS creates a single logical switch. This results in a single control plane for both management and configuration purposes. Whereas with vPC each Nexus switch (vPC) is managed and configured independently.
It is important to remember that with vPC both switches are managed independently. In turn meaning, you will need to create and permit your VLANs on both Nexus`s switches.
A. vPc would be the correct answer
