Question:
A wireless LAN is being deployed inside the new one room office that is occupied by the park ranger. The office is located at the highest part of the national park. After network testing is complete, the technicians report that the wireless LAN signal is occasionally affected by some type of interference. What are two possible causes of the signal distortion? (Choose two.)

• the microwave oven
• the large number of trees that surround the office
• the cellular phones that are used by the employees
• the elevated location where the wireless LAN was installed
• the number of wireless devices that are used in the wireless LAN

Explanation: Wireless LAN connectivity is not affected by trees or the elevation of the equipment. Because this is a one room office in an isolated area, there will not be a large number of wireless devices or source of interference operating in the immediate vicinity, apart from a cellular phone or a microwave oven.
