Which SD-WAN component is configured to enforce a policy that redirects branch-to-branch traffic to a network service (firewall or IPS)?

The vSmart controller is the correct answer because it is the centralized brain of the SD-WAN overlay network, responsible for orchestrating routing, security, and policy enforcement. When a policy needs to redirect branch-to-branch traffic to a network service like a firewall or IPS, the vSmart controller is where this policy is defined and pushed to the WAN Edge devices. vBond is incorrect because it is primarily an orchestrator for initial device authentication and onboarding, not for ongoing policy enforcement. WAN Edge devices are incorrect because they execute the policies, but the policies themselves are configured and distributed by the vSmart controller. A firewall is a network service, not an SD-WAN component responsible for policy orchestration within the SD-WAN fabric.
