CompTIA Security Plus Mock Test Q158

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.

Correct Answer: A
Section: Network Security

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.
