CWNA: Certified Wireless Network Administrator v108 — Question 34

A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device. What is the best solution for locating this non-802.11 device?

Answer options

• A. Access point spectrum analyzer
• B. Laptop-based spectrum analyzer with an omni-directional antenna
• C. Laptop-based spectrum analyzer with an omni-directional antenna
• D. Laptop-based spectrum analyzer with a directional antenna

Correct answer: D

Explanation

The best option is D, as a laptop-based spectrum analyzer with a directional antenna can help you pinpoint the source of interference more accurately by focusing on a specific direction. Options A, B, and C do not provide the same level of precision; an access point spectrum analyzer may not be designed for this purpose, while the omni-directional antennas in options B and C would pick up signals from all directions, making it harder to locate the specific device.
