A.A wireless repeater is an access point that is not connected to the wired LAN.
B.The repeater feature is only available in lightweight access point topologies.
C.The SSID of the root access point must be configured on the repeater access point.
D.This topology requires a 10 - 15 percent overlap between a wired access point and the wireless repeater.
E.This topology requires a 15 - 25 percent overlap between a wired access point and the wireless repeater.
F.To avoid interference， the repeater access point must use a different channel from what the root access point uses.

A.a drawback of implementing RSVP is the requirement to migrate to a supporting routing protocol
B.RSVP uses DSCP to signal QoS requirements to routers 
C.RSVP is a routing protocol
D.RSVP is an IP protocol that uses IP protocol ID 46， and TCP/UDP ports 3455
E.RSVP specifically provides a level of service for rate-sensitive and delay-sensitive traffic
F.the flow-based approach of RSVP is ideal for large， scalable implementations such as the public internet

A.The network shown in the output under the ip dhcp pool Central command should be changedto network 10.10.0.0 with a mask of 255.255.255.0
B.A second DHCP pool for network 10.10.0.0/24 should be configured
C.An ip dhcp excluded-address global configuration command for network 10.10.0.0/24 should beissued
D.The ip helper-address 10.0.0.1 command should be issued so that the address can be added tothe FastEthernet0/0 configuration
E.The ip helper-address 10.0.0.1 command should be issued so that the address can be added tothe FastEthernet0/1 configuration
