Which component distributes control-plane policies and routing information to SD-WAN edges?

• A. vBond
• B. vManage
• C. vSmart controller
• D. vEdge device

Answer: (C)

In Cisco SD-WAN, the vSmart controller is responsible for distributing control-plane policies and routing information to the SD-WAN edges. It acts as the central control plane, running the overlay logic and using the Overlay Management Protocol to share routing state and policy decisions with every vEdge. This enables consistent routing and policy enforcement across the entire fabric.

The other components have different roles: vBond handles initial authentication and rendezvous to bring edges into the network; vManage provides centralized management and configuration; and vEdge is the edge device that forwards user traffic and implements the policies and routing decisions learned from vSmart.
