Which controller provides centralized policy distribution and route control?

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

Answer: (D)

Centralized policy distribution and route control is handled by the SD-WAN control plane, implemented by the vSmart controller. vSmart sits between the management plane (vManage) and the data plane (WAN Edge devices), receiving policies from vManage and distributing them to all edges. It uses the Overlay Management Protocol to share routing information and enforcement rules, enabling consistent path selection and policy application across the entire fabric. The WAN Edges implement the actual forwarding according to these policies, while vBond handles authentication/bootstrap and vManage provides the configuration interface. This makes vSmart the central source of policy and route control rather than the other components.
