Which design achieves SD-WAN control plane redundancy?

The correct answer is D. Managing the underlay network with OMP. In Cisco SD-WAN, the control plane is implemented by vSmart controllers, which use OMP (Overlay Management Protocol) to distribute routing, policy, and security information to WAN Edge routers. Control plane redundancy is achieved by deploying multiple vSmart controllers; OMP…

Explanation

In Cisco SD-WAN, the control plane is implemented by vSmart controllers, which use OMP (Overlay Management Protocol) to distribute routing, policy, and security information to WAN Edge routers. Control plane redundancy is achieved by deploying multiple vSmart controllers; OMP ensures that WAN Edge routers can maintain connectivity and receive policy updates from any available vSmart controller in the topology. BFD (A) operates in the data plane between WAN Edge routers to detect path failures - it is not a control plane redundancy mechanism. vManage clusters (B) provide management plane (GUI/API) redundancy, not control plane redundancy. Deploying on a virtual platform like UCS or CSP (C) is an infrastructure placement consideration, not a redundancy design pattern. OMP (D) is the control plane protocol that underpins vSmart redundancy and failover.
