Which component provides centralized policy management, topology awareness, path selection, provisioning, telemetry, and end-to-end service orchestration across the SD-WAN fabric?

• A. SD-WAN Orchestrator provides centralized policy management, topology awareness, path selection, provisioning, telemetry, and end-to-end service orchestration across the fabric.
• B. SD-WAN Edge devices terminate underlay connections and enforce local QoS at the customer site.
• C. Underlay transport refers to the physical and virtual connectivity layers such as MPLS, Internet, and cellular.
• D. Management/Analytics plane handles encryption and firewall functions at the edge.

Answer: (A)

Coordinating and configuring the entire SD-WAN fabric across sites is the job of the SD-WAN Orchestrator. It provides centralized policy management to define consistent security, QoS, and routing rules, topology awareness to see the network layout and available paths, path selection to choose optimal routes, provisioning to onboard and configure devices automatically, telemetry to collect performance data, and end-to-end service orchestration to deliver and manage services across all edge devices.

The other components described focus on what happens at the edge or in the transport layers rather than the centralized control and coordination. Edge devices terminate underlay connections and enforce local QoS at the customer site. Underlay transport refers to the physical and virtual connectivity like MPLS, Internet, and cellular. The management/analytics plane handles management, telemetry, and governance functions, but the orchestration that unifies policy, path selection, provisioning, and end-to-end service delivery across the fabric is the orchestrator.
