300-420 Question 149
Select 3An enterprise is designing its WAN architecture to optimize application performance and improve traffic management for branch offices. The organization is considering implementing Cisco SD-WAN. Which of the following features of Cisco SD-WAN directly support these goals?
- A
Application-aware routing
- B
Centralized policy management
- C
Static routing configuration
- D
Dynamic path selection based on SLAs
- E
Circuit-based traffic segregation
Show answer and explanation
Correct answers: A, B, D
Explanation
Cisco SD-WAN is designed to optimize application performance and improve traffic management through features like application-aware routing, centralized policy management, and dynamic path selection based on SLAs. These features enable intelligent traffic steering and policy enforcement, which are critical for meeting the performance and management goals of an enterprise WAN architecture.
- A. Correct.
Application-aware routing is a key feature of Cisco SD-WAN that ensures application traffic is routed based on specific application requirements, contributing to improved application performance.
- B. Correct.
Centralized policy management allows administrators to define and enforce policies across the entire SD-WAN fabric, streamlining traffic management and ensuring consistent application performance across branch offices.
- C. Incorrect.
Static routing configuration is not a feature of Cisco SD-WAN; it is a traditional routing approach that lacks the dynamic capabilities needed for modern WAN optimization.
- D. Correct.
Dynamic path selection based on SLAs ensures that traffic is routed over the best available path based on real-time performance metrics, which enhances application performance and reliability.
- E. Incorrect.
Circuit-based traffic segregation is not a core feature of Cisco SD-WAN. SD-WAN focuses on abstracting and intelligently managing WAN links rather than relying on fixed circuit segregation.
