In Cisco SD-WAN, which two functions does OMP perform? (Choose two.)

OMP (Overlay Management Protocol) is the routing protocol of the Cisco SD-WAN overlay network. It advertises network prefixes (routes) learned from the connected sites, along with their associated attributes such as TLOCs (Transport Locators), VPN IDs, and service chains. This information allows vSmart controllers to build the network topology and determine optimal paths. OMP also delivers crypto keys to vEdge routers, which are essential for establishing secure IPsec tunnels between them, ensuring encrypted communication across the overlay. Configuration of control and data policies is primarily handled by the vManage NMS, which then pushes these policies to the vSmart controllers. Gathering of underlay infrastructure data is typically done by the vEdge routers and reported to vManage, not directly by OMP. Segmentation and differentiation of traffic are functions of VPNs and QoS policies, respectively, managed by vManage and enforced by vEdge routers.
