CWNA: Certified Wireless Network Administrator v107 — Question 36

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 a directional antenna.
• D. Laptop-based spectrum analyzer with an omni-directional antenna.

Correct answer: A

Explanation

An access point spectrum analyzer is specifically designed to detect interference across the entire spectrum, making it the best choice for locating non-802.11 devices. In contrast, laptop-based spectrum analyzers may not provide as comprehensive coverage, especially when using antennas that are omni-directional or directional, which could limit their effectiveness in pinpointing the source of interference.
