CompTIA Network+ (N10-008) — Question 737

Users are reporting issues with connecting to the wireless router. The technician discovers neighboring wireless APs that are not part of the network are on the same 5GHz frequency. Which of the following best describes the issue?

Answer options

• A. Distance limitation
• B. Absorption
• C. Signal-to-noise ratio
• D. Interference

Correct answer: D

Explanation

The correct answer is D, as interference occurs when multiple devices operate on the same frequency, causing communication problems. Distance limitation refers to the range of the signal, absorption pertains to signal loss through materials, and signal-to-noise ratio measures the clarity of the signal, none of which directly describe the effect of neighboring APs on the same frequency.
