Exam 220-1101 topic 1 question 240 discussion

The issue is related to interference from the microwave, which operates at 2.4GHz, the same frequency as some Wi-Fi channels. To avoid this interference, the technician should configure the Wi-Fi access point (AP) to use a 5GHz band, which has more channels and less interference from other devices. Changing the Wi-Fi operation channel may not solve the problem if the microwave interferes with multiple channels. Increasing the power output of the AP may not overcome the interference and may cause more interference to other devices. Changing the SSID to hidden does not affect the interference at all, and may make it harder for users to connect to the network.

I think A is the correct answer because changing it to 5GHz will disconnect other devices that solely rely on 2.4GHz. Selecting the right channel can significantly improve your Wi-Fi coverage and performance

B. Configure the Wi-Fi AP to 5GHz. Explanation: The issue described, where the Wi-Fi connection drops every time the microwave is used, suggests interference in the 2.4GHz frequency range. Microwave ovens commonly operate on the 2.4GHz frequency, and their use can interfere with Wi-Fi signals.

B, since question is looking for a long-term solution

Microwave Interference: Microwave ovens typically operate in the 2.4GHz frequency band. When a microwave is in use, it can emit electromagnetic interference in the 2.4GHz range, which can disrupt Wi-Fi signals in the same frequency band. This interference is a common cause of Wi-Fi dropouts. 5GHz Band: The 5GHz frequency band is less susceptible to interference from common household devices like microwaves and cordless phones that operate in the 2.4GHz band. By configuring the Wi-Fi AP to use the 5GHz band, you can reduce the likelihood of interference and improve Wi-Fi reliability.

most likely

The issue is likely caused by interference between the Wi-Fi signal and the microwave's operation on the 2.4GHz frequency band. By configuring the Wi-Fi access point (AP) to operate on the 5GHz frequency band, it will help avoid interference from household devices like microwave ovens, cordless phones, and Bluetooth devices that typically operate on the 2.4GHz band.

I think the answer is B. Here is my why. To my understanding, most microwaves operate in the 2.5GHZ. Therefore when the microwave is used, it is causing the interference with the WIFI. Changing the Wi_Fi operation channel is usually used when the Wi-Fi channel is crowed (when using the 2.5 GHZ use channel 1, 6, or 11). The question doesn't say anything about to many users on one channel. Anyway, that is my though.

I think B may be the answer.
