A.
Disable the wired ports

B.
Use channels 1, 4 and 7 only

C.
Enable MAC filtering

D.
Disable SSID broadcast

E.
Switch from 802.11a to 802.11b

Explanation:
Network administrators may choose to disable SSID broadcast to hide their network from unauthorized
personnel. However, the SSID is still needed to direct packets to and from the base station, so it’s a
discoverable value using a wireless packet sniffer. Thus, the SSID should be disabled if the network isn’t for
public use.
A MAC filter is a list of authorized wireless client interface MAC addresses that is used by a WAP to block
access to all unauthorized devices.
