300-435 Question 234
Single answerA network engineer is configuring a Cisco SD-WAN environment for a multinational organization. The goal is to ensure that certain critical applications, such as voice and video, are prioritized across the WAN links, while less critical traffic, like file transfers, uses any remaining bandwidth. Which Cisco SD-WAN feature should be implemented to achieve this objective?
- A
Application-Aware Routing
- B
Bidirectional Forwarding Detection (BFD)
- C
TLOC Color Mapping
- D
Dynamic Path Selection
Show answer and explanation
Correct answer: A
Explanation
Application-Aware Routing is a key feature of Cisco SD-WAN that enables traffic to be routed dynamically based on application performance requirements, such as latency, jitter, or packet loss. This makes it ideal for prioritizing critical applications like voice and video. The other options, while relevant to Cisco SD-WAN, do not address application prioritization specifically.
- A. Correct.
Application-Aware Routing is the correct choice because it allows traffic to be routed based on application characteristics and performance metrics. Using this feature, the engineer can prioritize critical applications like voice and video.
- B. Incorrect.
Bidirectional Forwarding Detection (BFD) is used to monitor link status and detect failures quickly, but it does not prioritize applications based on their importance.
- C. Incorrect.
TLOC Color Mapping is used to define and identify Transport Locator (TLOC) paths in the SD-WAN fabric but does not provide application prioritization or routing capabilities.
- D. Incorrect.
Dynamic Path Selection enables traffic to switch between WAN paths based on performance metrics, but it does not specifically prioritize traffic by application.
