The correct answers are A. Identify the location of devices that utilize 2.4GHz and D. Map all of the wireless signals in the restaurant. In order to troubleshoot the issue, the technician should first identify the location of devices that utilize the 2.4GHz frequency, as this can cause interference with the wireless signal. Additionally, the technician should map all of the wireless signals in the restaurant in order to identify any potential sources of interference. Checking to see if the phones are IJTP or STP lines, testing to see if the copper electrical wires are causing interference, verifying T568B is being used in the wiring closet patch panel, and scheduling timed router reboots throughout the day are not necessary steps for troubleshooting this issue.

I feel like if youre truly mapping ALL the wireless signals, youre going to find the devices that use 2.4GHz band anyway. Im going with CD.

Identify the location of devices that utilize 2.4GHz (Option A): Wireless networks can be impacted by interference from devices using the same frequency range. Many devices, such as cordless phones and certain types of consumer electronics, operate on the 2.4GHz frequency. Identifying the location of such devices and either relocating them or choosing a less congested wireless channel can help mitigate interference.

I mean, I don't get this question. It's wireless right? So what's with all this wires in questions? I choose this, but not sure. Option A is about wireless signal, but ridiculous, or I don't get it. Anyway I hope somebody who is sure will answer.

answer A is about how microwaves and other devices can interfere on 2.4 GHz frequency, which this wifi might be on. i guess identifying if the microwave in the kitchen is really close to the access point would be the first step, then changing that access point to 5GHz to remedy the issue
