Two sites are using a multisite centralized call processing model. The voice gateway on the remote branch has lost IP connectivity to its Cisco CallManager server. Which feature enables the remote gateway to take the role of the call agent during the WAN failure？ （）

A.to support fault and policy reporting， the WLSE requires a Wireless Control System （WCS）
B.when WLSE detects an AP failure， it automatically increases the power and cell coverage of nearby APs
C.WLSE requires the 2700 location appliance to offer location tracking
D.WLSE can locate rogue APs and automatically shut them down
E.WLSE configuration is done using the command line interface （CLI） or a WEB based template

A.policy routing
B.increase link capacity
C.WRED
D.CBWFQ
E.LFI
F.WFQ

A.TKIP protects RC4 encryption keys
B.CKIP and TKIP protect AES encryption keys
C.TKIP encryption is more processor intensive than AES encryption is
D.WPA requires TKIP encryption， whereas WPA2 supports AES encryption
E.WPA requires AES encryption， whereas WPA2 supports TKIP encryption
