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
