Exhibit： 

You work as a network technician at. Study the exhibit carefully. You are required configure the static WEP keys on the wireless client adapter using the Cisco ADU （Aironet Desktop Utility）. 
What should you have in mind when doing this？（）

A . Before the client adapter WEP key is generated， all wireless infrastructure devices （such as access points， servers， etc.） must be properly configured for LEAP authentication.
B . The client adapter WEP key should be generated by the AP and forwarded to the client adapter efore the client adapter can establish communication with the wireless network.
C . In infrastructure mode the client adapter WEP key must match the WEP key used by the access point. In ad hoc mode all client WEP keys within the wireless network must match each other.
D . The client adapter WEP key should be generated by the authentication server and forwarded to the client adapter before the client adapter can establish communication with the wireless network.
E . None of the other alternatives apply
