300-430 Question 59
Select 3An enterprise is deploying a wireless LAN controller (WLC) and wants to prioritize business-critical applications like WebEx and Microsoft Teams while de-prioritizing recreational traffic such as video streaming or social media. The IT team decides to implement Application Visibility and Control (AVC) with Fastlane on the WLC. Which steps are required to configure this solution effectively?
- A
Enable AVC on the WLC to monitor and classify applications.
- B
Configure QoS profiles to map specific DSCP values to application traffic.
- C
Enable Fastlane on the wireless clients without modifying the WLC.
- D
Apply AVC profiles to specific WLANs to enforce policies.
- E
Disable QoS settings on the WLC to avoid conflicts with AVC.
Show answer and explanation
Correct answers: A, B, D
Explanation
To implement AVC with Fastlane on a WLC, you must enable AVC to monitor and classify application traffic, configure QoS profiles to map DSCP values for prioritization, and apply AVC profiles to WLANs to enforce traffic policies. These configurations ensure that business-critical applications are prioritized while recreational traffic is de-prioritized. Simply enabling Fastlane on clients or disabling QoS on the WLC would not achieve the desired outcome.
- A. Correct.
Enabling AVC on the WLC is the first step to monitor and classify application traffic. Without this, the WLC cannot detect or prioritize application data.
- B. Correct.
Configuring QoS profiles allows the WLC to map the appropriate DSCP values to application traffic, ensuring proper prioritization for business-critical applications.
- C. Incorrect.
Fastlane requires configuration on both the WLC and the clients. Merely enabling Fastlane on the wireless clients without WLC-side configuration will not achieve the desired effect.
- D. Correct.
AVC profiles must be applied to specific WLANs to enforce application-based policies. This ensures that traffic prioritization occurs on the correct SSIDs.
- E. Incorrect.
Disabling QoS on the WLC would prevent traffic prioritization entirely, which is counterproductive to the goal of prioritizing business-critical applications.
