300-425 Question 58
Select 3You are configuring a Cisco Wireless LAN Controller (WLC) to optimize application performance for an enterprise network. The network requires prioritization for business-critical applications like WebEx while ensuring recreational applications like video streaming are limited in bandwidth usage. Which steps should you take to implement AVC with Fastlane on the WLC?
- A
Enable Application Visibility and Control (AVC) on the WLC and apply an AVC profile to the WLAN.
- B
Configure a QoS profile on the WLC and enable it for the WLAN.
- C
Enable Fastlane on the WLAN and prioritize DSCP markings for business-critical applications.
- D
Disable AVC to prevent interference with Fastlane QoS prioritization.
- E
Manually classify applications and configure bandwidth limits per application on the WLC.
Show answer and explanation
Correct answers: A, B, C
Explanation
To implement AVC with Fastlane on a Cisco WLC, you need to enable AVC to gain application-level visibility and control, configure QoS profiles to prioritize traffic, and enable Fastlane to optimize DSCP markings for business-critical applications. Disabling AVC or relying on manual classification is not required because AVC automates these processes, ensuring efficient traffic management and enhanced application performance.
- A. Correct.
Correct: Enabling AVC on the WLC allows application-level visibility and control in the network, which is a prerequisite for AVC-based traffic management.
- B. Correct.
Correct: Configuring a QoS profile helps prioritize traffic based on DSCP markings and ensures proper traffic shaping for better application performance.
- C. Correct.
Correct: Fastlane prioritizes traffic for business-critical applications by leveraging QoS and DSCP markings, which is essential in this scenario.
- D. Incorrect.
Incorrect: Disabling AVC would prevent the WLC from identifying applications and enforcing traffic policies, defeating the purpose of AVC.
- E. Incorrect.
Incorrect: Manual classification is not required as AVC automatically identifies applications and applies policies based on predefined profiles.
