350-401 Question 29
Select 3An enterprise is planning to deploy a wireless network in a high-density environment, such as a large conference room with over 300 users connecting simultaneously. Which of the following design considerations will best ensure optimal wireless performance for high client density?
- A
Use a high number of access points with overlapping channels to maximize coverage.
- B
Enable band steering to encourage devices to use the 5 GHz spectrum.
- C
Reduce the transmit power of access points to minimize co-channel interference.
- D
Implement a minimum RSSI value for client association.
- E
Deploy access points with omnidirectional antennas for uniform signal coverage.
Show answer and explanation
Correct answers: B, C, D
Explanation
In high-density wireless environments, strategies like enabling band steering, reducing transmit power, and setting minimum RSSI thresholds are critical to optimize performance and minimize interference. Overlapping channels and inappropriate antenna selection can cause interference and degrade performance, making careful planning and configuration essential.
- A. Incorrect.
Using a high number of access points with overlapping channels may lead to excessive co-channel interference, degrading performance in high-density environments.
- B. Correct.
Enabling band steering encourages clients to use the 5 GHz band, which has more available channels and less interference compared to 2.4 GHz, helping to optimize performance in dense environments.
- C. Correct.
Reducing the transmit power of access points helps to minimize co-channel interference, which is critical in high-density scenarios where multiple access points are deployed.
- D. Correct.
Implementing a minimum RSSI value ensures that only clients with a strong signal connect to the access point, thereby improving overall performance in dense environments.
- E. Incorrect.
While omnidirectional antennas provide uniform coverage, they are not always the best choice for high-density environments, where focused directional antennas may perform better in certain scenarios.
