A Chief Executive Officer (CEO) decided that only a limited number of authorized company
workstations will be able to connect to the Internet. Which of the following would BEST accomplish
this goal?

A.
Use content filtering

B.
Install and configure IDS

C.
Enable MAC address filtering

D.
Enable RAS on the network firewall

Explanation:
Most Wi-Fi access points and routers ship with a feature called hardware or MAC address
filtering. This feature is normally turned “off” by the manufacturer, because it requires a bit of
effort to set up properly. However, to improve the security of your Wi-Fi LAN (WLAN), strongly
consider enabling and using MAC address filtering.
