What is an advantage of using the VPC feature in data center environment ?

The correct answer is A. All available uplinks bandwidth is used. Virtual Port Channel (vPC), a Cisco Nexus feature, allows a port channel to be split across two physical switches that form a vPC peer pair. From the perspective of a connected device (server or switch), it sees a single logical port channel, but both uplinks terminate on…

Explanation

Virtual Port Channel (vPC), a Cisco Nexus feature, allows a port channel to be split across two physical switches that form a vPC peer pair. From the perspective of a connected device (server or switch), it sees a single logical port channel, but both uplinks terminate on different physical switches. Because there are no STP-blocked ports, both uplinks forward traffic simultaneously, utilizing 100% of available uplink bandwidth. The two switches do NOT merge into a single control plane (each maintains its own); FHRP may still be needed; and each switch retains its own management IP address.
