Which control plane protocol is used between Cisco SD-WAN routers and vSmart controllers?

Answer options

• A. TCP
• B. OMP
• C. UDP
• D. BGP

Correct answer: B

Explanation

The correct answer is B, OMP (Overlay Management Protocol), which is specifically designed for the communication needs of Cisco SD-WAN. TCP and UDP are transport layer protocols and are not used for control plane communication in this context, while BGP is primarily a routing protocol and not the control plane protocol utilized by Cisco SD-WAN.
