You work as the network operator at Certkiller .com. A user has entered the wrong WEP (Wired
Equivalent Privacy) key into a wireless device. Which of the following symptoms will occur?

A.
Data can be sent but not received.

B.
The network cannot be accessed.

C.
Data cannot be sent but can be received.

D.
The network can only be accessed using the Service Set Identifier.

Explanation:
WEP requires that both the wireless computer and the WAP (wireless access point) be configured
with the same encryption key in order for the two to communicate. If one of the two has the wrong
WEP key, communication will not be possible and the network will not be accessible.
