Correct answer: It is the data plane that is responsible for forwarding traffic.
Why this is the answer
The WAN Edge (formerly cEdge or vEdge) operates in the data plane, forwarding user traffic across the SD-WAN fabric. It establishes secure tunnels (IPsec or GRE) to other WAN Edge devices, applies policies for traffic steering and quality of service (QoS), and performs encryption/decryption. Incorrect options: Orchestration is the role of vManage, which assists with automatic provisioning. Centralized configuration and monitoring are functions of vManage, which acts as the management plane. Building and maintaining network topology is the responsibility of vSmart, which serves as the control plane.
