Select two benefits of implementing a traditional WAN instead of an SD-WAN solution.

Traditional WANs, often relying on static routing and MPLS, typically have lower control plane abstraction because routing decisions are made by individual devices based on pre-configured protocols, rather than a centralized controller. This can simplify understanding for engineers familiar with traditional routing. They also tend to have lower data plane overhead as they often use simpler encapsulation methods (e.g., MPLS, PPP) compared to SD-WAN solutions that frequently add additional headers for overlay tunnels (e.g., IPsec, GRE). Faster fault detection and simplified troubleshooting are generally benefits of SD-WAN due to centralized visibility and automation. Comprehensive configuration standardization is a key advantage of SD-WAN, not traditional WANs, as SD-WAN enables policy-driven, template-based deployments.
