, 1.A university deploys a new Wi-Fi network in a lecture hall where over 200 students
connect at the same time using modern devices.
Which combination of frequency band and channel width would provide the **best
performance** and **least interference** in this dense environment?
A. 2.4 GHz with 40 MHz channels
B. 5 GHz with 160 MHz channels
C. 2.4 GHz with 20 MHz channels
D. 6 GHz with 80 MHz channels
Answer: D
Explanation:
In a high-density environment with modern devices, 6 GHz offers wide, clean
spectrum with less legacy interference. 80 MHz provides high throughput while
avoiding the interference risks of 160 MHz in congested areas.

What is the **most likely technical reason** for this problem?
A. Wide channels overlapping and increasing interference
B. Clients only supporting 2.4 GHz band
C. Excessive collision detection by CSMA/CD
D. Channel width too narrow for high data rates
Answer: A
Explanation:
160 MHz channels are wide and can easily overlap with other nearby APs using the
same frequency. This leads to increased interference and instability in shared
environments. A narrower width (40/80 MHz) may perform better.
