Which component authenticates and facilitates device bootstrap in Cisco SD-WAN?

• A. vBond orchestrator
• B. vSmart controller
• C. vManage GUI-based management plane
• D. vEdge device

Answer: (A)

Think about the first step a new device takes when joining the SD-WAN: it must prove who it is and be guided to the right place to become part of the overlay. The vBond orchestrator handles that gatekeeping. It authenticates the device—usually with a certificate or pre-installed credentials—and makes sure only authorized devices can join. Once identity is verified, vBond provides the device with the location of the vSmart controllers and helps establish the initial control-plane path, so the device can register and set up the tunnels needed for the overlay.

This role is distinct from the other components. The vSmart controller runs the overlay control plane, distributing policies and managing routing within the SD-WAN once devices are enrolled. The vManage GUI-based management plane is used for centralized configuration and monitoring, not for the initial bootstrap authentication. The vEdge device is the endpoint that will join the network, but the authentication and bootstrap coordination are performed by vBond, not by the edge itself.
