300-415 Question 171
Single answerAn organization is implementing an application-aware routing policy in their Cisco SD-WAN environment to route video conferencing traffic over MPLS links and less critical traffic over the internet. Which type of policy must be used to ensure this behavior?
- A
Centralized Data Policy
- B
Localized Control Policy
- C
Centralized Control Policy
- D
Localized Data Policy
Show answer and explanation
Correct answer: A
Explanation
To implement application-aware routing in a Cisco SD-WAN solution, a Centralized Data Policy is required. This type of policy enables the traffic to be classified and forwarded based on application types or other characteristics, such as routing video conferencing traffic over a high-quality MPLS link. Other policy types, such as Control Policies, are used for different purposes like route advertisement or adjacency manipulation.
- A. Correct.
Centralized Data Policy is the correct option because it is used to enforce application-aware routing decisions across the SD-WAN fabric. It allows traffic to be routed based on application type, such as routing video conferencing traffic over MPLS links.
- B. Incorrect.
Localized Control Policy is incorrect because it is typically applied at the local level on individual devices and is focused on adjacency and routing table manipulation rather than application-aware routing.
- C. Incorrect.
Centralized Control Policy is incorrect because it deals with route advertisement and does not control the forwarding path of application traffic.
- D. Incorrect.
Localized Data Policy is incorrect because it is applied at the local device level and is not used for application-aware routing across the SD-WAN fabric.
