Study the exhibit shown below carefully. A Cisco Aironet Wireless LAN Client Adapter has been installed and configured through the ADU on the PC. The Aironet System Tray Utility （ASTU） has been enabled during the installation and the icon appears in the system tray area in the lower right of the desktop as shown：
What is the significance of this icon？ （）
A. It indicates that the client adapter is not associated to an access point or another client.
B. It indicates that the radio of the client adapter is disabled.
C. It indicates that the client adapter is associated to an access point or another client， but the user is not EAP authenticated.
D. It indicates that the client adapter is associated to an access point or another client， that theuser is authenticated if the client adapter is configured for EAP authentication， and that the signal strength is poor.
E. It indicates that the client adapter is associated to an access point or another client， that the user is authenticated if the client adapter is configured for EAP authentication， and that the signal strength is fair.
F. It indicates that the client adapter is associated to an access point or another client， that the user is authenticated if the client adapter is configured for EAP authentication， and that the signal strength is excellent or good.

A. Antenna power is a relative value reference to dBi.
B. LWAPP allows encrypted communications between lightweight access points and WLAN controllers.
C. Characteristics of antennas are directionality， gain， and polarization.
D. Power over Ethernet （PoE） is only available when a WLAN controller is integrated into the network.
E. The WLAN solution Engine （WLSE） is used to control lightweight access points.
F. One of the advantages of the lightweight WLAN solution is that the devices act indepently.

A. Adaptive Wireless Path （AWP）
B. WLAN Quality of Service （WQoS）
C. Lightweight Access Point Protocol （LWAPP）
D. 802.1Q WLAN trunking protocol
E. Layer 2 Roaming （IAPP）
Refer to the exhibit.
Which statement is true about the repeater access point that is deployed in this wireless network？（）
A. The repeater access point should use a different SSID than the SSID configured on the parent access point.
B. The repeater access point reduces the throughput in half because it receives and then retransmits each packet on the same channel.
C. The repeater access point requires a 10 percent channel overlap with channel of the root access point.
D. The repeater access point should use a different WEP encryption method than the WEP encryption that is enabled on the parent access point.

Refer to the exhibit. Switch S2 contains the default configuration. Switches S1 and S3 both have had the command spanning-tree mode rapid-pvst issued on them. What will be the result？（）
During routine maintenance， G1/0/1 on DS1 was shutdown. All other interface were up. DS2 became the active HSRP device for Vlan101 as desired. However， after G1/0/1 on DS1 was reactivated. DS1 did not become the active HSRP device as desired. What need to be done to make the group for Vlan101 function properly ？ （）
Refer to the exhibit. Initially， LinkA is connected and forwarding traffic. A new LinkB is then attached between SwitchA and HubA. Which two statements are true about the possible result of attaching the second link？（）
Refer to the exhibit and the partial configuration of switch SW_A and SW_B. STP is configured on all switches in the network. SW_B receives this error message on the console port：00：06：34： %CDP-4-DUPLEX_MISMATCH： duplex mismatch discovered on FastEthernet0/5 （not half duplex）， with SW_A FastEthernet0/4 （half duplex） ， with TBA05071417（Cat6K-B） 0/4 （half duplex）. What would be the possible outcome of the problem？（）
Refer to the exhibit. STP has been implemented in the network. Switch SW_A is the root switch for the default VLAN. To reduce the broadcast domain， the network administrator decides to split users on the network into VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 root primary on switch SW_A. What will happen as a result of this change？（）
