Question 8:
You are a network technician, study the exhibit carefully. What should be taken into consideration when using the Cisco Aironet Desktop Utility (ADU) to configure the static WEP keys on the wireless client adapter?
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 before 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.
Answer: C
Question 9:
You work as a network technician ,please study the exhibit carefully. When it attempts to register to a wireless LAN controller (WLC), what type of message is transmitted by the lightweight access point (LAP)?

B – The LAP will send Layer 2 Lightweight Access Point Protocol (LWAPP) mode discovery request messages only.
C – The LAP will send Layer 3 Lightweight Access Point Protocol (LWAPP) mode discovery request messages only.
D – The LAP will send Layer 2 Lightweight Access Point Protocol (LWAPP) mode discovery request messages. If the attempt fails, the LAP will try Layer 3 LWAPP WLC discovery.
