Which component authenticates WAN Edge devices and orchestrates secure controller connectivity?

• A. vManage
• B. vBond
• C. vSmart
• D. FMC

Answer: (B)

The key idea is the bootstrap for the SD-WAN fabric. The vBond orchestrator is responsible for authenticating WAN Edge devices and guiding them to the controllers. When a WAN Edge boots, vBond verifies the device’s identity (via certificates or credentials) and then provides the edge with the addresses of the vSmart and vManage controllers it should connect to. It also helps with establishing the control-plane paths and handling NAT traversal so the edge can securely reach and establish TLS sessions with the controllers. Once authenticated, the edge can register and participate in the overlay. Other components have different roles: vManage is the management plane for configuration and telemetry, vSmart runs the central control plane for the overlay, and FMC handles security policies and enforcement. They don’t perform the initial device authentication or orchestrate the bootstrap connectivity of edges.
