How are policies deployed on cloud-hosted Cisco SD-WAN controllers?
The correct answer is C. Policies are created on vManage and enforced by vSmart. In Cisco SD-WAN, policies are centrally defined and configured on the vManage controller, and then pushed to the vSmart controller for distribution and enforcement throughout the network.

Why each option
In Cisco SD-WAN, policies are centrally defined and configured on the vManage controller, and then pushed to the vSmart controller for distribution and enforcement throughout the network.
vManage is the management plane for policy creation, but vSmart is the control plane responsible for the actual enforcement of policies on the data plane devices.
Policies are created and managed on vManage, not vSmart, and vManage does not enforce policies; vSmart does.
The vManage controller serves as the centralized management plane where network administrators create, modify, and activate all SD-WAN policies. These policies are then deployed or pushed to the vSmart controllers, which act as the centralized control plane, responsible for distributing these policies to the WAN Edge devices and enforcing them across the overlay network.
Policies are created on vManage, not vSmart, although vSmart is indeed responsible for enforcing the policies it receives from vManage.
