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.
In the Company wireless LAN，
what is the function of the Service Set Identifier （SSID）？（）
A. The SSID must match on both the Company client and the Company access point and provides MAC Address Authentication to authenticate the client to the access point.
B. The SSID should be configured on the Company client site only and provides data-privacy functions and authentication to the access point.
C. The SSID must match on both the Company client and the Company access point and provides encryption keys for authentication to the access point.
D. The SSID must match on both the Company client and the Company access point. The SSID is advertised in plain-text in the access point beacon messages.
E. None of the other alternatives apply

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？（）
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）.
