Changing Network Parameters

The Chief Information Officer (CIO) has noticed the corporate wireless signal is available in the parking lot.

Management requests that the wireless network be changed so it is no longer accessible in public areas, without affecting the availability inside the building.

Which of the following should be changed on the network?

A.

Power levels

B.

Overcapacity

C.

Distance limitations

D.

Channel overlap.

A.

The correct answer is A. Power levels.

Explanation: Wireless signals can be affected by several factors, including power levels, overcapacity, distance limitations, and channel overlap. In this scenario, the corporate wireless signal is available in the parking lot, which means that the signal is reaching beyond the intended area of coverage. This issue can be addressed by adjusting the power levels of the wireless access points (WAPs).

By decreasing the power levels, the signal's coverage area can be reduced, which means that the wireless network will no longer be accessible in public areas such as the parking lot. However, the availability of the wireless network inside the building should not be affected as long as the WAPs are properly configured and placed.

Overcapacity and distance limitations are not relevant to this scenario. Overcapacity refers to a situation where the number of devices connected to a wireless network exceeds the network's capacity, causing performance issues. Distance limitations refer to the maximum distance that a wireless signal can travel before losing strength and becoming unusable.

Channel overlap occurs when two or more wireless networks are using the same channel, causing interference and reducing performance. While channel overlap can affect the availability and performance of a wireless network, it is not relevant to this scenario.
