300-435 Question 235
Single answerYou are tasked with deploying a Cisco SD-WAN solution for a multinational organization. One of the requirements is to implement traffic engineering policies to ensure that critical applications, such as video conferencing, always use the most reliable and low-latency path, while less critical applications, such as file transfers, can use a best-effort path. Which Cisco SD-WAN feature should you use to meet this requirement?
- A
Application-Aware Routing
- B
TLOC Extension
- C
Dynamic Multipoint VPN (DMVPN)
- D
BGP Route Filtering
Show answer and explanation
Correct answer: A
Explanation
The organization requires traffic engineering policies that prioritize critical applications based on network performance. Application-Aware Routing in Cisco SD-WAN analyzes network and application performance metrics and dynamically routes traffic over the most optimal path, ensuring the requirements for critical and less-critical applications are met. None of the other options provide this capability within Cisco SD-WAN.
- A. Correct.
Application-Aware Routing allows Cisco SD-WAN to dynamically select the best transport path for specific application traffic based on performance metrics like latency, jitter, and packet loss, making it the correct choice for this scenario.
- B. Incorrect.
TLOC Extension is used to extend transport locators (TLOCs) to another device for redundancy but does not address application-specific traffic routing.
- C. Incorrect.
Dynamic Multipoint VPN (DMVPN) is not part of the Cisco SD-WAN solution and is a different technology used for VPN connectivity in traditional WANs.
- D. Incorrect.
BGP Route Filtering is used to control the advertisement and acceptance of BGP routes but does not provide application-based traffic engineering.
