220-1201 Practice Question: A technician is configuring a wireless network…
A technician is configuring a wireless network for a high-density environment such as a conference hall. The network must support hundreds of simultaneous connections with minimal interference. Which configuration will best achieve this?
⚠ Common exam trap
Test-takers frequently assume higher transmit power always improves coverage and performance, but in high-density environments, it actually increases co-channel interference and reduces overall network capacity.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy multiple access points with reduced transmit power and non-overlapping channels
In a high-density environment like a conference hall, deploying multiple access points with reduced transmit power and non-overlapping channels (e.g., 1, 6, 11 for 2.4 GHz) minimizes co-channel interference and allows efficient frequency reuse, supporting hundreds of simultaneous connections. This design increases overall capacity by creating smaller, manageable cells that reduce contention and improve throughput per client.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single high-power access point to cover the entire hall
Why it's wrong here
A single high-power access point, while potentially providing signal coverage, cannot efficiently manage hundreds of simultaneous client connections in a high-density environment. Each client competes for airtime on a single channel, leading to excessive collisions, retransmissions, and severe network congestion. This significantly degrades overall throughput and user experience, making it unsuitable for large gatherings where numerous devices are active.
- ✓
Deploy multiple access points with reduced transmit power and non-overlapping channels
Why this is correct
Deploying multiple access points with reduced transmit power creates smaller, manageable wireless cells, allowing for efficient client load balancing across several devices. Utilizing non-overlapping channels (e.g., 1, 6, 11 for 2.4 GHz, or numerous channels in 5 GHz) minimizes co-channel interference between adjacent APs. This strategy maximizes overall network capacity and provides a robust, high-performance experience for a large number of users.
- ✗
Disable the 5 GHz band to reduce complexity
Why it's wrong here
Disabling the 5 GHz band would significantly reduce the available wireless spectrum and the number of non-overlapping channels, which is counterproductive in a high-density scenario. The 5 GHz band offers substantially more channels and is less susceptible to interference from common household devices compared to 2.4 GHz. Restricting clients solely to 2.4 GHz would quickly lead to severe congestion and diminished performance for all connected devices.
- ✗
Enable WPS for faster client connections
Why it's wrong here
Enabling Wi-Fi Protected Setup (WPS) is a significant security vulnerability due to its susceptibility to brute-force attacks on the PIN, compromising network security. Furthermore, WPS is designed for simplified initial client connection, not for improving network capacity, throughput, or performance in a high-density environment. It offers no benefit for managing numerous simultaneous connections and introduces unnecessary risk.
