Ann, a sales manager, successfully connected her company-issued smartphone to the wireless network in
her office without supplying a username/password combination. Upon disconnecting from the wireless
network, she attempted to connect her personal tablet computer to the same wireless network and could
not connect.
Which of the following is MOST likely the reason?

A.
The company wireless is using a MAC filter.

B.
The company wireless has SSID broadcast disabled.

C.
The company wireless is using WEP.

D.
The company wireless is using WPA2.

Explanation:
MAC filtering allows you to include or exclude computers and devices based on their MAC address.
Incorrect Answers:
B: because she could connect to the wireless with the first device, the SSID must be broadcasting.
C, D: Both WEP and WPA2 require a password or phrase.
