CompTIA Network+ (N10-007) — Question 170

Joe, a network engineer, is attempting to install wireless in a large work area. He installs the access point in the middle of the work space. When testing, he notices a -60dB reading on one side of the room and a -92dB reading on the other side. Which of the following is MOST likely the issue?

Answer options

• A. External interference
• B. Distance limitations
• C. Channel overlap
• D. Incorrect antenna type

Correct answer: D

Explanation

The correct answer is D, as using the wrong type of antenna can significantly affect the signal strength in different areas, leading to large discrepancies in dB readings. Options A, B, and C may contribute to signal quality issues but are less likely to cause such a drastic difference in signal strength as seen here.
