Refer to the exhibit. Which of the following is an advantage of device clustering utilizing Virtual Port Channels （vPC）？（）

A.A logical star topology provides a loop free environment so that all links will be used forwardtraffic

B.Enhanced EtherChannel hashing load balancing using the vPC peer link internal to the VPC

C.The control plane functions of the Nexus switches are merged to hide the use of virtualization

D.Neighboring devices connect on a Layer 3 MEC for improved packet forwarding
