Which two Lightweight Access Point statements are true？（）
A. An AP that has been upgraded from an autonomous AP to lightweight AP will only function in conjunction with a Cisco Wireless LAN controller.
B. LWAPP increases the amount of processing within the APs， enabling them to support filtering and policy enforcement features.
C. WLAN controllers provide a single point of management.
D. Lightweight APs require local configurations using local management.
E. Real time events such as authentication， security management， and mobility are handled by the lightweight AP.
F. Autonomous APs receive control and configuration information from a WLAN controller.
On the Company wireless LAN， A client is searching for an access point （AP）.
What is the correct process order that this Company client and access point goes through in order to create a connection？（）
A. association request/response， probe request/response， authentication request/response
B. association request/response， authentication request/response， probe request/response
C. probe request/response， authentication request/response， association request/response
D. probe request/response， association request/response， authentication request/response
E. None of the other alternatives apply
Refer to the exhibit. The signal transmitted from the AP is reflected off a wall resulting in multipath interference at the client end.
Which statement is true？ （）
A. The transmitted signal from the AP arrives at the client at slightly different times resulting in phase shifting.
B. If signal 2 is close to 360 degrees out of phase with signal 1， the result is essentially zerosignal or a dead spot in the WLAN.
C. Multipath interference is less of an issue when using a DSSS technology because multipath is frequency selective.
D. If signal 1 is in phase with signal 2， the result is essentially zerosignal or a dead spot in the WLAN.
E. Multipath interference is solved by using dual antennas.
You work as a network technician at Company. Please study the exhibit carefully. In this
Company wireless network， the LAP （lightweight access point） attempts to register to a WLC （Wireless LAN Controller）.
What kind of message is transmitted？（）
A. The lightweight access point will send Layer 2 and Layer 3 Lightweight Access Point （LWAPP） mode discovery request messages at the same time.
B. The lightweight access point will send Layer 3 Lightweight Access Point （LWAPP） mode discovery request messages only.
C. The lightweight access point will send Layer 2 Lightweight Access Point （LWAPP） mode
D.iscovery request messages. If the attempt fails， the LAP will try Layer 3 LWAPP WLC discovery. D. The lightweight access point will send Layer 2 Lightweight Access Point （LWAPP） mode discovery request messages only.
LDAP is being used throughout the Company wireless network.
Which statement about the Lightweight Access Point Protocol （LWAPP） protocol is true？（）
A. The processing of 802.11 data and management protocols and access point capabilities is distributed between a lightweight access point and a centralized WLAN controller.
B. LWAPP advertises its WDS capability and participates in electing the best WDS device for the wireless LAN.
C. LWAPP aggregates radio management forward information and sends it to a wireless LAN solution engine.
D. LWAPP authenticates all access points in the subnet and establishes a secure communication channel with each of them.
E. None of the other alternatives apply
