Atechnician is configuring a soho wireless router for a small business with three
employees. after the three employees laptops have successfully connected to the wireless
network, the company would like to prevent additional access to the wireless network. the
technician enables wpa2 on the wireless router. which of the following additional settings
should the technician change?

a. enable mac filtering
b. disable ssid broadcast
c. reduce radio power level
d. update router firmware

A. Enable MAC filtering

Explanation:

A media access control (MAC) address is a unique identifier for any hardware connected on a network. The MAC address cannot be changed and is specified from the manufacturer of the device through the network card. In this scenario MAC filtering will only allow devices whose MAC addresses are configured in the allowed list of the router to have network access. If DHCP is enabled, only the allowed devices will be assigned IP addresses via DHCP for network access .MAC filtering protects the network from access by unauthorized devices.
