350-401 Question 30
Single answerAn enterprise is designing a wireless network for a large auditorium that frequently hosts conferences with over 500 attendees, all using Wi-Fi devices. The network team wants to ensure optimal performance by addressing high client density. Which strategy should be prioritized to support this requirement?
- A
Deploy access points (APs) with high transmit power to cover the entire auditorium with fewer APs.
- B
Enable features like band steering and load balancing to distribute clients evenly across available APs.
- C
Use legacy 802.11b devices to ensure broad compatibility for all Wi-Fi clients.
- D
Increase the channel width to 80 MHz to maximize throughput for each AP.
Show answer and explanation
Correct answer: B
Explanation
High client density environments, such as an auditorium with a large number of Wi-Fi users, require specific optimizations to ensure reliable performance. Features like band steering and load balancing are critical because they help distribute clients efficiently across access points and frequency bands. This minimizes congestion on any single AP and ensures better resource availability for all connected devices. Other options, like high transmit power and wider channel widths, can increase interference and degrade performance in such scenarios.
- A. Incorrect.
Deploying APs with high transmit power can lead to co-channel interference in a high-density environment, which negatively impacts performance. This is not a recommended strategy for high client density scenarios.
- B. Correct.
Enabling features like band steering and load balancing helps distribute clients across available 2.4 GHz and 5 GHz bands and prevents overloading a single AP. This is an effective strategy for high-density environments.
- C. Incorrect.
Using legacy 802.11b devices limits the overall network performance due to lower data rates and increased airtime consumption. This would hinder the network's ability to handle high client density.
- D. Incorrect.
Increasing the channel width to 80 MHz reduces the number of available non-overlapping channels, increasing co-channel interference in dense environments. Narrower channel widths (e.g., 20 MHz) are typically preferred in high-density scenarios.
