300-425 Question 60
Select 3A network administrator is tasked with improving application performance for a high-density wireless network in an enterprise environment. The Wireless LAN Controller (WLC) is running in the latest version and supports Fastlane. The administrator also wants to prioritize business-critical applications and throttle non-essential ones using Application Visibility and Control (AVC). Which configuration steps should the administrator take to achieve this?
- A
Enable AVC on the Wireless LAN Controller (WLC) and select the SSIDs where it should be applied.
- B
Configure application policies in the WLC to prioritize business-critical applications and restrict unwanted traffic.
- C
Enable Fastlane on the WLC and ensure that client devices support 802.11k and 802.11v.
- D
Enable QoS with the Platinum profile on the SSID to boost performance for all applications.
- E
Use the WLC to create custom AVC profiles and apply them to specific WLANs.
Show answer and explanation
Correct answers: A, B, E
Explanation
To implement AVC with Fastlane on a WLC, the administrator must first enable AVC and select the SSIDs to apply it. They also need to configure application-specific policies within the WLC to prioritize or restrict traffic as needed. Creating custom AVC profiles ensures granular control over application behavior. While Fastlane can enhance QoS for supported devices, it is not essential for AVC itself, and enabling global QoS profiles like Platinum does not provide the same application-specific control as AVC.
- A. Correct.
Enabling AVC on the WLC is a prerequisite to utilize its features for monitoring and controlling application traffic. Additionally, selecting the SSIDs ensures AVC policies are applied correctly.
- B. Correct.
Application policies must be configured to prioritize or restrict traffic based on the business needs. This is a core component of AVC functionality.
- C. Incorrect.
Fastlane is used to optimize QoS for iOS devices and requires specific client-side support. It is not directly required to implement AVC policies.
- D. Incorrect.
Enabling QoS Platinum profile provides high-priority access for all traffic on the SSID, but it lacks the granular control over specific applications that AVC offers.
- E. Correct.
Custom AVC profiles allow the administrator to define and apply specific rules for applications, aligning them with the organization's requirements.
