Which policy type applies application-aware traffic engineering decisions?

• A. Data policy
• B. Control policy
• C. AAA policy
• D. Logging policy

Answer: (A)

Application-aware traffic engineering decisions are made in the data plane, where forwarding is decided per flow based on the application's identity, requirements, and SLA needs. A data policy defines how traffic should be treated and steered, enabling app-aware routing and path selection, QoS, and other forwarding actions that optimize transmission for different applications. This is why data policy is the best fit for application-aware TE decisions: it directly governs how traffic is forwarded and which paths are chosen to meet application requirements, rather than influencing control-plane behavior, authentication, or logging.
