300-415 Question 178
Select 3You are tasked with configuring a data policy in a Cisco SD-WAN solution to ensure that all traffic from a specific application is forwarded through a high-priority MPLS link, while other internet-bound traffic uses a lower-cost broadband link. What configuration steps must you include to achieve this?
- A
Create a data policy to match the specific application traffic and set a preferred MPLS transport link.
- B
Apply the data policy to the outbound direction on the required WAN Edge router.
- C
Configure a centralized control policy to influence routing decisions for the application traffic.
- D
Match the internet-bound traffic in the data policy and ensure it is forwarded to the broadband link.
- E
Apply the data policy to the inbound direction on the required WAN Edge router.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure a data policy to forward specific application traffic through an MPLS link and other internet-bound traffic through a broadband link, you must create a data policy to match both traffic types and define the appropriate forwarding actions. This policy must be applied outbound on the WAN Edge router to influence traffic leaving the router. A control policy is not required in this scenario, as it deals with route advertisement and not traffic forwarding.
- A. Correct.
Correct: A data policy must be created to identify traffic based on the specific application and enforce the use of the MPLS link.
- B. Correct.
Correct: Data policies must be applied on the outbound direction of the WAN Edge router to influence traffic forwarding decisions.
- C. Incorrect.
Incorrect: A control policy is used for routing decisions, but in this case, a data policy is more appropriate for forwarding specific application traffic.
- D. Correct.
Correct: The data policy must also match internet-bound traffic and direct it to the broadband link to meet the requirements.
- E. Incorrect.
Incorrect: Data policies are not applied on the inbound direction; they must be applied outbound to influence egress traffic.
