CompTIA A+ Core 1 (220-1101) — Question 160

A user submitted a help desk ticket to report that the Wi-Fi connection drops every time the microwave is used. A technician suspects the issue is related to interference. Which of the following should the technician do to provide the BEST long-term solution for the issue?

Answer options

• A. Change the Wi-Fi operation channel.
• B. Configure the Wi-Fi AP to 5GHz.
• C. Increase the power output of the AP.
• D. Change the SSID to hidden.

Correct answer: B

Explanation

The best long-term solution is to configure the Wi-Fi AP to 5GHz (Option B), as this frequency is less susceptible to interference from household appliances like microwaves, which primarily operate on the 2.4GHz band. Changing the Wi-Fi operation channel (Option A) may help, but it won't completely eliminate the interference. Increasing the power output of the AP (Option C) could strengthen the signal but won't address the underlying interference issue. Changing the SSID to hidden (Option D) does not resolve the interference problem at all.
