What are two characteristics of a migration from an IP-VPN service to a Cisco SD-WAN...

A migration from traditional IP-VPN service to Cisco SD-WAN commonly increases security and scalability. Cisco SD-WAN builds encrypted data-plane tunnels across supported transports, so the enterprise can use Internet, MPLS, or hybrid connectivity while maintaining secure site-to-site communication. The architecture also scales better operationally because policy, templates, onboarding, and routing control are centralized through the SD-WAN controllers and management plane. Increased solution complexity is not a desired characteristic; one of the design goals is to simplify operations through automation and centralized policy. Centralized application policies are also a major SD-WAN benefit, but when only two choices are selected, the stored answer emphasizes the two broad migration outcomes of security and scale. Distributed control plane is not correct because Cisco SD-WAN uses centralized control-plane logic with vSmart controllers distributing OMP routes and policies. A professional migration plan should validate transport diversity, controller redundancy, encryption policy, application-aware routing, and operational readiness.
