Why each option
vSmart functions primarily as the control plane in Cisco SD-WAN, responsible for policy enforcement and key management through key reflection.
vSmart performs key reflection, which involves generating and securely distributing encryption keys to WAN Edge devices. This process ensures that data plane tunnels (IPsec/GRE) between WAN Edge devices are secured with consistent and appropriate encryption keys.
NAT traversal is primarily a function handled by the vBond orchestrator, which assists WAN Edge devices in establishing tunnels through Network Address Translation devices.
Device template creation is a function performed by vManage, the centralized management platform, not by vSmart.
Monitoring and telemetry data collection are primarily functions of vManage, which aggregates and displays information from all network devices.
