CompTIA A+ Core 2 Question H-18

A small business owner is setting up their wireless network in their office, which is in a building shared with several other businesses. The owner does not want to disable the SSID broadcasting due to visiting customers needing to use the network, but does not want other businesses to notice the network, let alone access it. Which of the following would BEST accomplish this?

A. Configure the access point encryption from unsecured access to WEP.
B. Adjust the radio power so that coverage is restricted to the business.
C. Change the SSID to reflect the business name instead of a public access point.
D. Enable MAC filtering and restrict access to other company’s devices.

Correct Answer: B

Best way to do this is to adjust radio power to restrict the coverage to the business. When the radio power is restricted to an office. The persons in the other office space cannot detect the signals at all.
