Which component pushes and enforces centralized policies across the SD-WAN fabric?

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

Answer: (D)

Central policy distribution across the SD-WAN fabric is handled by the control plane component that acts as the central policy engine. This node takes the centralized policies created in the management plane and disseminates them to all WAN Edge devices, ensuring consistent routing, security, and QoS decisions across the network. The edges then enforce these policies in their data plane.

The other components have different roles: WAN Edge devices carry out the actual data-plane forwarding; vBond handles initial authentication and bootstrap; and vManage is where administrators author and configure policies, dashboards, and devices, but the pushing and enforcement of those policies across the fabric is driven by the central policy distribution component.
