300-425 Question 56
Single answerA network administrator is configuring Application Visibility and Control (AVC) with Fastlane on a Cisco Wireless LAN Controller (WLC) to optimize application performance for a corporate network. The administrator needs to ensure that critical business applications like Webex and Office 365 receive the highest priority while limiting bandwidth for recreational applications such as social media. Which step is essential to achieve this configuration?
- A
Enable AVC on the WLC and apply the pre-configured QoS Fastlane policy.
- B
Create a custom AVC profile and map it to the WLAN without enabling Fastlane.
- C
Enable QoS Fastlane directly on the WLAN and rely on default AVC profiles.
- D
Enable AVC and configure application policies for specific traffic types on the WLC.
Show answer and explanation
Correct answer: D
Explanation
To implement AVC effectively with Fastlane, the administrator must enable AVC on the WLC and configure specific application policies to prioritize or limit bandwidth for certain types of traffic. Fastlane ensures that real-time and critical business applications receive the necessary quality of service (QoS), while AVC provides visibility and control over application traffic. This combination allows the administrator to optimize network performance based on organizational needs.
- A. Incorrect.
This option is incorrect because enabling AVC and applying a pre-configured QoS Fastlane policy does not allow granular control over specific application traffic types.
- B. Incorrect.
This option is incorrect because creating a custom AVC profile without enabling Fastlane does not ensure that real-time applications receive the necessary prioritization.
- C. Incorrect.
This option is incorrect because enabling QoS Fastlane without configuring AVC application policies does not provide the ability to manage or shape traffic effectively.
- D. Correct.
This option is correct because enabling AVC and configuring application policies on the WLC allows the administrator to prioritize critical applications like Webex and Office 365 while restricting bandwidth for less important ones such as social media.
