Which of the following statements about OMP is true?

• A. Encrypts data traffic
• B. Maintains STP topology
• C. Polls SNMP configurations
• D. Exchanges routes and policies between controllers and edge devices

Answer: (D)

OMP is the control-plane protocol in the SD-WAN architecture that distributes routing information and policy decisions between the central controllers and the edge devices. This is why the statement about exchanging routes and policies between controllers and edge devices is correct: it captures OMP’s core role in coordinating how traffic is routed across the network and how policies are applied on the edge devices. It’s not about encrypting the actual data payload (that’s handled by the data-plane security like IPsec), nor about maintaining Layer 2 STP topology, nor about polling SNMP configurations. OMP focuses on how routes and policies are shared and synchronized across the control and edge planes.
