Correct answer: Uses NETCONF to configure vSmart devices and build the overlay data plane..
Why this is the answer
vManage is the centralized network management system for Cisco SD-WAN. It uses NETCONF (Network Configuration Protocol) to configure vSmart controllers and other SD-WAN components. NETCONF is a robust, XML-based protocol designed for network device configuration, providing a programmatic and standardized way to manage network devices. This allows vManage to push configurations to vSmart controllers, which then establish the control plane and build the overlay data plane by distributing routing and policy information to the WAN Edge devices. The other options are incorrect: vManage uses NETCONF for configuration, not an "overlay management protocol." While SD-WAN can integrate with legacy networks using routing protocols like OSPF, this is typically handled by WAN Edge devices, not a direct function of vManage's core operation. WAN Edge devices use a secure control plane (DTLS/TLS) to discover and connect to vBond orchestrators, not necessarily requiring a public IP for discovery of all fabric components.
