CompTIA Network+ (N10-007) — Question 150

The network team at a university, which has on-campus residences, recently expanded the WiFi offerings to the dormitories. Each dormitory houses approximately 75 students, who each have multiple wireless devices. The WLAN utilizes an intelligent wireless controller for configuration and management. While the WiFi in academic buildings continues to receive few to no complaints, dormitory complaints are on the rise. Which of the following is MOST likely causing the complaints?

Answer options

• A. Frequency mismatch
• B. Crosstalk
• C. Interference
• D. Channel overlap

Correct answer: C

Explanation

The most likely cause of the complaints is interference, which can occur due to numerous devices operating in the same frequency range, leading to poor connectivity and performance. While frequency mismatch, crosstalk, and channel overlap can also cause issues, interference is the most common problem in densely populated areas like dormitories with many devices competing for bandwidth.
