Which policy is processed locally on a WAN Edge router rather than centrally by vSmart?

• A. Centralized control policy
• B. Localized data policy
• C. Application-aware policy
• D. Security policy

Answer: (B)

In SD-WAN, decisions that directly affect how traffic is forwarded can be handled at the edge, separate from the central controller. The localized data policy is the set of rules installed on each WAN Edge that the edge enforces on its own data plane. This lets the edge make fast forwarding, QoS, and path decisions locally, even if the central controller (vSmart) isn’t reachable. Centralized control policy, by contrast, is created and pushed by vSmart to govern routing and control-plane behavior network-wide. Application-aware and security policies are typically defined in the centralized management plane and enforced across edges, though some enforcement can occur at the edge as part of the broader policy set. So the policy that’s processed locally on the WAN Edge is the localized data policy.
