300-415 Question 176
Single answerYou are tasked with implementing a Cisco SD-WAN solution for a retail organization that needs to prioritize point-of-sale (POS) traffic across all branches while ensuring that large file transfers do not consume excessive bandwidth. To achieve this, you decide to configure a data policy. Which action should you take to meet these requirements?
- A
Define a data policy that matches POS traffic and applies a TLOC route with high priority.
- B
Create a centralized data policy to match large file transfers and apply a rate-limiting action.
- C
Configure a localized control policy to prioritize POS traffic at branch edges.
- D
Use an application-aware routing policy to prioritize POS traffic over large file transfers.
Show answer and explanation
Correct answer: B
Explanation
To meet the requirements, a centralized data policy is the appropriate choice as it allows traffic matching and manipulation at the data plane level. By applying a rate-limiting action to large file transfers, you can prevent them from consuming excessive bandwidth, ensuring sufficient resources for critical POS traffic. Data policies are specifically designed for such traffic prioritization and control use cases.
- A. Incorrect.
Defining a data policy to match POS traffic and applying a TLOC route with high priority is incorrect because TLOC routes are typically used for directing traffic to specific transport locations, not for prioritization.
- B. Correct.
Creating a centralized data policy to match large file transfers and applying a rate-limiting action is correct because data policies are designed for manipulating traffic behavior, and rate-limiting ensures large file transfers do not consume excessive bandwidth.
- C. Incorrect.
Configuring a localized control policy to prioritize POS traffic is incorrect as control policies influence routing decisions, not traffic prioritization or bandwidth management.
- D. Incorrect.
Using an application-aware routing policy is incorrect because application-aware routing is used to dynamically select the best path for specific applications based on performance metrics, not for bandwidth prioritization.
