300-415 Question 170
Select 3An enterprise organization has deployed Cisco SD-WAN across their branches. They want to ensure that all video conferencing traffic is prioritized over other types of traffic and is routed through a low-latency MPLS link when available. Additionally, they want to ensure that file transfer traffic is only routed through the public internet. How can this be achieved using Cisco SD-WAN policies?
- A
Create a centralized data policy to prioritize video conferencing traffic and match it to MPLS links with the lowest latency.
- B
Configure an Application-Aware Routing policy to dynamically route video conferencing traffic based on SLA performance thresholds.
- C
Use a centralized control policy to block file transfer traffic on the MPLS transport.
- D
Apply a localized data policy on each branch device to classify video conferencing traffic and apply QoS prioritization.
- E
Implement a centralized data policy to match file transfer traffic and define an action to route it exclusively through the public internet.
Show answer and explanation
Correct answers: A, B, E
Explanation
To meet the requirements, centralized data policies can be used to classify and prioritize video conferencing traffic and ensure file transfer traffic is routed through the public internet. Additionally, Application-Aware Routing is suitable for dynamically steering video conferencing traffic based on SLA thresholds. Control policies are not appropriate for traffic prioritization, and localized data policies are not scalable for this use case.
- A. Correct.
This is correct. A centralized data policy can be used to match video conferencing traffic and prioritize it, ensuring it is routed to MPLS links with the desired performance characteristics.
- B. Correct.
This is correct. Application-Aware Routing policies can dynamically route traffic based on SLA thresholds, making it suitable for ensuring video conferencing traffic uses the best available path.
- C. Incorrect.
This is incorrect. While control policies can be used to influence routing decisions, blocking file transfer traffic on MPLS may not meet the requirement to route it through the public internet.
- D. Incorrect.
This is incorrect. Localized data policies apply only at the local device level and are not scalable for enterprise-wide traffic prioritization.
- E. Correct.
This is correct. A centralized data policy can explicitly match file transfer traffic and define the public internet as the preferred path, meeting the requirement.
