CompTIA A+ Core 1 (220-1101) — Question 509

A Wi-Fi mesh network has been optimized to eliminate poor coverage areas, yet users still experience decreased bandwidth and connectivity issues. Which of the following actions should the technician take NEXT?

Answer options

• A. Relocate any large, dense, solid, and metal objects, such as mirrors and file cabinets, in the mesh network coverage area to the perimeter so that wireless reflections, absorptions, and occlusions are minimized.
• B. Use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.
• C. Use the signal strength indicator on a mobile device to roam the coverage area and generate a heat map to isolate zones with weak signals.
• D. Turn off broadcasting of the SSID on the mesh network so that other networks cannot see it.

Correct answer: B

Explanation

The correct answer is B because using a Wi-Fi analyzer can help identify if the current channel is overcrowded and suggest a better one, which can significantly enhance performance. Options A and C address physical obstacles and signal strength but do not directly resolve bandwidth issues related to channel congestion. Option D is not a solution to connectivity problems and can actually make the network less accessible.
