Explanation

The vSmart controller is the SD-WAN component responsible for enforcing centralized control policies, including service chaining to redirect traffic like branch-to-branch flows to network services.

Common mistakes.

A. vBond is the orchestrator, primarily used for initial authentication and coordination, not for policy enforcement.
C. WAN Edge routers execute policies, but the policies themselves for centralized traffic redirection are configured and pushed from vSmart.
D. A firewall is a service device, not an SD-WAN component that configures or enforces SD-WAN policies.

Concept tested. vSmart centralized policy enforcement
