Exam 350-401 topic 1 question 112 discussion

Correct Options are B & E.

B&E, LED has no impact on wifi

B & E are correct Radar systems operate in similar frequency bands as Wi-Fi networks and can cause interference, especially if they are in close proximity to Wi-Fi devices. Radar signals can disrupt Wi-Fi signals, leading to degraded performance or even complete loss of connectivity. Rogue APs are unauthorized access points that are set up within a Wi-Fi network without the knowledge or approval of the network administrator. These rogue APs can cause interference by competing with the authorized APs for channel space and bandwidth. They can disrupt the network and degrade the performance of legitimate Wi-Fi devices.

Correct Options are B & E.

BE are correct D might have been right if they stated microwave oven as these ovens operate on the 2.4GHz band. However conventional ovens don't produce microwave radiations so D is wrong.

B & E correct!

How LED light impact Wifi ?

Radar uses the same radio band as 5gHz wifi

provided answer is correct

It should be BE

A, B, and E can all be correct. A is less likely with modern LED lights but can occur with budget lights. B is very unlikely to occur unless you live near an airfield or military installation. E is obvious. Given most setups are not near an airfield, the answer is A and E.

B,E a re the correct answers

B & E https://documentation.meraki.com/MR/WiFi_Basics_and_Best_Practices/Common_Sources_of_Wireless_Interference

The microwave can cause some interference but not the oven, the led light interference is way too small that doesn’t effect anything at all, the humidity density can cause some Interface, humans body, water, tree, rain, snow… can cause good a substantial amount of radio lost but for this question and given answer the radar and rogue AP is the correct answer, remember the submarine can not transmit the signal from while floating under the water, so they float the antenna to the surface when they want to communicate with the central command.

The correct answer is: B. radar E. rogue AP

common sources of interference for Wi-Fi networks: 1. florescent lights; not LED lights 2. Radar is source of WiFi interference 3. Security motion detectors; not fire alarm 4. Microwave oven; not conventional oven 5. Rogue AP so B & E are correct!!!

A E. I have read that in Network+ before. Radar is a valid answer, but you probably won't have a radar i nearby your WLAN, which means it's not a common reason.
