Which policy construct controls centralized route advertisement and acceptance behavior?

• A. QoS policy
• B. Control policy
• C. Access policy
• D. Logging policy

Answer: (B)

Routing advertisement and acceptance in a centralized SD-WAN environment are governed by a control policy. This policy construct defines how routes are shared between devices (which routes to advertise, to which links, and which routes to accept), and it can assign attributes or filtering rules to shape routing decisions across the network. By centralizing these rules, the controller ensures consistent routing behavior across all sites.

Other policy types serve different purposes: QoS policy manages how traffic is treated (priority, bandwidth, shaping); Access policy controls who or what can connect or access resources; Logging policy determines what events are recorded. None of these directly steer which routes are advertised or accepted, which is why the control policy is the appropriate choice.
