Which component represents the WAN Edge device in the SD-WAN architecture?

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

Answer: (D)

The WAN Edge is the actual device at the customer site that terminates the SD-WAN overlay and connects to the transport network. It sits at the edge of the network—the branch or remote site—where local traffic is encapsulated into SD-WAN tunnels, chosen for the best path, and then sent over the WAN. The other components are control and management planes: vBond handles onboarding and initial connectivity, vSmart distributes routing and policies across the fabric, and vManage provides centralized provisioning and management. Together they support the edges, but the device at the edge itself—the WAN Edge—is the component that represents the edge device in SD-WAN.
