CompTIA Security+ Question E-62

A company provides secure wireless Internet access for visitors and vendors working onsite. Some of the vendors using older technology report that they are unable to access the wireless network after entering the correct network information. Which of the following is the MOST likely reason for this issue?

A. The SSID broadcast is disabled.
B. The company is using the wrong antenna type.
C. The MAC filtering is disabled on the access point.
D. The company is not using strong enough encryption.

Answer: A

When the SSID is broadcast, any device with an automatic detect and connect feature is able to see the network and can initiate a connection with it. The fact that they cannot access the network means that they are unable to see it.
