Which characteristic applies to a traditional WAN solution but not to a Cisco SD-WAN solution?

Traditional WAN solutions typically involve complex, device-by-device manual configuration and maintenance for routing and security policies, resulting in significant time consumption compared to the centralized and automated approach of SD-WAN.

Centralized reachability, security, and application policies are hallmarks and key benefits of Cisco SD-WAN, managed through vManage, which contrasts with the typically decentralized policy management of traditional WANs.

Low complexity and increased overall solution scale are advantages offered by Cisco SD-WAN solutions, while traditional WANs often become highly complex and difficult to scale.

Cisco SD-WAN solutions inherently operate over DTLS/TLS authenticated and secured tunnels (e.g., IPsec) for secure communication, which is a core feature, whereas traditional WANs may or may not implement such comprehensive tunnel security.
