I need to upgrade to an unlimited plan

Which of these would be the best choice to prevent communication to a wireless access point?



A) SSID broadcast suppression

B) Static IP addressing

C) MAC filtering

D) Modification of the default access point username and password

E) Disable everyone’s texting plan

The answer: C) MAC filtering

The MAC address is a hardware address associated with a network adapter. By filtering specific MAC addresses on an access point, you can limit the devices that can communicate to a network device.

SSID broadcast suppression limits visibility of the wireless network, but does not prevent communication. Static IP address also does not prevent communication to an access point.
