Which SD-WAN component distributes centralized policies and orchestrates route advertisements between WAN Edge devices?

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

Answer: (A)

In SD-WAN, the central control plane is responsible for pushing policies and coordinating routing between WAN Edge devices. This role is filled by vSmart. It takes centralized policies defined in vManage and distributes them to the WAN Edges, while running the routing control mechanism that exchanges and propagates VPN routes among the edges so traffic follows the intended paths across the network.

vManage handles the GUI, policy creation, and overall management of the fabric, but it does not perform the dynamic distribution of policies or route advertising. vBond takes care of initial authentication and bootstrap connectivity to bring devices into the fabric. ISE is not part of the SD-WAN fabric's core components.
