CompTIA Network+ (N10-008) — Question 745

A company commissioned a site survey to check wireless network coverage. The technician noticed undesirable levels of RSSI in different areas of the office. Which of the following levels did the technician most likely notice?

Answer options

• A. -82dBm
• B. -61dBm
• C. 42dBm
• D. 63dBm

Correct answer: A

Explanation

The correct answer is A (-82dBm), which indicates a weak signal and is typically considered undesirable for reliable wireless connectivity. Levels such as -61dBm (B) are generally acceptable for good performance, while positive values like 42dBm (C) and 63dBm (D) suggest a very strong signal, which would not be classified as undesirable.
