CompTIA A+ 220-1101 Practice Question

The correct answer is the detection of overlapping channels which can cause co-channel interference and degrade the performance of a wireless network. The WiFi analyzer helps in identifying channels that are overlapping with other nearby networks, allowing the technician to choose a less congested channel for the affected wireless network. Knowledge about signal strength is more about the coverage area rather than interference, SSIDs identification does not address interference issues directly, and while finding unauthorized access points is important for security, it does not focus on finding sources of interference affecting network performance.
