300-415 Question 297
Select 2An enterprise is deploying Cisco SD-WAN and plans to use AppNav for WAN optimization in their network. During the implementation, they realize that specific design considerations must be made to integrate AppNav with SD-WAN. Which of the following is a requirement or limitation when integrating AppNav into a Cisco SD-WAN solution?
- A
AppNav must be deployed in inline mode with SD-WAN Edge devices.
- B
AppNav supports traffic redirection for TCP-based flows only.
- C
AppNav requires integration with Cisco WAAS for optimization functionality.
- D
AppNav can only be deployed in a centralized SD-WAN controller environment.
- E
AppNav automatically handles asymmetric routing in SD-WAN deployments.
Show answer and explanation
Correct answers: B, C
Explanation
AppNav is a Cisco solution designed to manage and redirect traffic for WAN optimization purposes. It works in conjunction with Cisco WAAS to optimize TCP-based traffic. When integrating AppNav with Cisco SD-WAN, it is important to consider its focus on TCP traffic and dependency on WAAS for optimization. It does not require inline deployment and does not inherently solve asymmetric routing challenges, which must be addressed separately in the SD-WAN design.
- A. Incorrect.
Incorrect: AppNav does not require inline deployment; it supports virtual inline or out-of-path deployment modes, making it flexible for SD-WAN integration.
- B. Correct.
Correct: AppNav is designed to optimize traffic for TCP-based flows only, as WAN optimization typically focuses on improving TCP performance.
- C. Correct.
Correct: AppNav requires integration with Cisco WAAS (Wide Area Application Services) to provide optimization functionality, as AppNav itself is a traffic redirection and management solution.
- D. Incorrect.
Incorrect: AppNav can be deployed in both centralized and distributed SD-WAN environments, depending on the network design and requirements.
- E. Incorrect.
Incorrect: AppNav does not automatically handle asymmetric routing. Proper routing configurations must be implemented to ensure symmetrical routing for optimized traffic.
