Which policy type is described as centralized data policy in SD-WAN?

• A. Localized data policy
• B. Data policy
• C. Centralized control policy
• D. Centralized data policy

Answer: (D)

In SD-WAN, data policies govern how traffic is processed on the data plane. When policy is centralized, the rules are defined in the central orchestrator (vSmart) and pushed to all edge devices, ensuring uniform behavior across the network. This is described as a centralized data policy. It lets you update and enforce the same traffic handling, QoS, and security rules everywhere from a single place. Localized data policy would apply rules per device, leading to inconsistency. A generic data policy doesn’t specify centralization, and centralized control policy deals with control-plane decisions like routing, not how data is handled on the data plane. So the described policy type is centralized data policy.
