Which two functions does vSmart perform? (Choose two.)

The vSmart controller is central to the SD-WAN control plane. It orchestrates connectivity by distributing routing, policy, and security information to WAN Edge routers, defining the network topology. It also builds secure control-plane connections with WAN Edges using TLS (Transport Layer Security) or DTLS (Datagram Transport Layer Security) to exchange this critical information. Incorrect options: Ensuring WAN Edge routers can establish control-plane connectivity is a broader network function, not solely performed by vSmart. Validating authorized WAN Edges is primarily the role of vManage and the controller-mode vBond, which handles initial authentication and orchestration. TLOCs are used by WAN Edge routers to identify their interfaces, not a function performed by vSmart itself.
