What type of analyzer can evaluate Wi-Fi network availability as well as help optimize Wi-Fi signal settings or identify Wi-Fi security threats?

• A. Network performance monitor
• B. Wi-Fi analyzer
• C. Spectrum scanner
• D. Security auditor

Answer: (B)

The main idea here is a tool that specifically handles wireless performance while also surfacing security issues. A Wi‑Fi analyzer is built for wireless networks, measuring signal strength across the coverage area, identifying dead zones, and showing which channels are crowded or affected by interference. With that information, you can choose the cleanest channel, adjust transmit power, or reposition access points to improve availability and overall performance. It also looks for security-related clues, such as rogue access points, unusual devices connecting to the network, or weak encryption, helping you detect and address threats. That combination—evaluating network availability and performance while guiding optimization and flagging security concerns—makes a Wi‑Fi analyzer the best fit. Other tools tend to focus on broader network metrics, RF activity in general, or security posture separately, without tying wireless availability, optimization, and threat detection together.
