Which SD-WAN component handles the control plane and fabric orchestration?

• A. WAN Edge
• B. vBond
• C. vSmart
• D. vManage

Answer: (C)

The control plane and fabric orchestration in SD-WAN is handled by the vSmart controller. It runs the control plane for the fabric and makes policy decisions, distributing routing information and application-aware policies to all WAN Edge devices. Using the Overlay Management Protocol, vSmart propagates state, routes, and control decisions to the edges so they can establish tunnels and choose optimal paths according to centralized policies. It coordinates with other components—vBond handles device admission/authentication and vManage provides centralized provisioning and monitoring—while the WAN Edge devices focus on forwarding data plane traffic. So, vSmart is the component that directly manages the control plane and the fabric orchestration.
