300-430 Question 246
Select 3During a wireless network deployment, you need to configure a Cisco Wireless LAN Controller (WLC) to optimize network performance for a high-density environment, such as a lecture hall. Which of the following configuration steps should you take on the WLC to handle the high user density effectively?
- A
Enable Dynamic Channel Assignment (DCA) with a reduced channel width for 5 GHz.
- B
Disable Client Load Balancing to avoid client disconnections.
- C
Adjust the Minimum RSSI for client association to prevent low-quality connections.
- D
Enable Band Steering to encourage dual-band clients to connect to the 5 GHz band.
- E
Set the maximum data rate for 2.4 GHz to 54 Mbps to improve throughput.
Show answer and explanation
Correct answers: A, C, D
Explanation
In high-density environments, optimizing WLC configurations is critical to ensure efficient use of available spectrum and resources. Dynamic Channel Assignment (DCA) helps reduce interference, adjusting the Minimum RSSI prevents low-quality connections, and enabling Band Steering directs clients to the 5 GHz band for better performance. Disabling Client Load Balancing or setting high data rates for 2.4 GHz can negatively impact network performance.
- A. Correct.
Dynamic Channel Assignment (DCA) with reduced channel width (e.g., 20 MHz) for 5 GHz helps minimize co-channel interference and is particularly effective in high-density environments.
- B. Incorrect.
Disabling Client Load Balancing is not recommended, as it helps distribute clients evenly across access points to avoid overloading a single AP.
- C. Correct.
Adjusting the Minimum RSSI for client association ensures that only clients with an acceptable signal strength can connect, which prevents poor-quality connections that may degrade performance in high-density scenarios.
- D. Correct.
Enabling Band Steering encourages dual-band clients to connect to the less congested 5 GHz band, which provides better performance in high-density environments.
- E. Incorrect.
Setting the maximum data rate for 2.4 GHz to 54 Mbps is not a recommended practice, as it may increase interference and degrade performance in a high-density setup.
