To implement a regional hub topology across multiple data centers in a retail SD‑WAN, which construct is used?

A control policy on vManage is used to implement a regional hub topology. vManage is the centralized network management system for Cisco SD-WAN, and control policies define how the overlay network behaves, including routing and topology. By configuring a control policy on vManage, you can specify which data centers act as regional hubs and how branches connect to them, ensuring traffic flows through the desired paths. An app route policy on vSmart is incorrect because it focuses on application-specific routing decisions rather than overall network topology. A data policy on vSmart is incorrect because it primarily handles traffic forwarding based on data plane characteristics, not control plane topology. A control policy on vSmart is incorrect because while vSmart enforces control policies, vManage is the platform where these policies are centrally configured and pushed to the vSmart controllers.
