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

A.The router will distribute IP addresses from pool 1 until its addresses are exhausted. Then therouter will begin distributing addresses from pool 2
B.The configuration is invalid because the DHCP options are global configuration commands
C.The configuration is incomplete until the DHCP pools are bound to the appropriate interface orinterfaces
D.The router will choose which pool to use based upon the interface the DHCP request wasreceived on

A.Hosts belonging to DHCP pool 1 and pool 2 will retain their IP settings for 30 hours before theymust renew
B.Hosts will receive IP settings from pool 1 until the addresses run out， and then hosts will receivethe settings from pool 2
C.Hosts in the 10.10.20.0/24 subnet will use 10.10.20.50 as its DNS server
D.DHCP pool 0 needs to have the ip dhcp excluded-address command to exclude the defaultrouter and DNS servers

A.DHCPDISCOVER packets will reach the DHCP server
B.The router will not forward DHCPDISCOVER packets because it has not been configured to doso.
C.This configuration is applied to interface Fa0/1
D.DHCPDISCOVER packets will not reach the DHCP server because DHCPDISCOVER packetsare broadcasts
E.DHCPDISCOVER packets will not reach the DHCP server because ports 67 and 68 have notbeen explicitly allowed by the ip forward-protocol command
F.This configuration is applied to interface Fa0/0

A.DHCP requests from the host will be rebroadcasted to R2
B.To complete this configuration， the R1 fa0/0 interface must be configured with the ip helper-addresses command
C.To complete this configuration， the R2 fa0/0 interface must be configured with the ip helper-addresses command
D.R1 will forward all DHCP requests to both 192.168.100.1 and 192.168.200.1 as unicastmessages
E.R1 will forward DHCP requests to 192.168.100.1. If there is no response， R1 will then forwardthe requests to 192.168.200.1

A.Router R2 will distribute incorrect default router option information to DHCP clients because it isimporting this information from R1
B.As configured， router R2 will retrieve domain name and other option information from R1
C.For the import all command to work on router R2， its Fa0/1 interface must be configured as aDHCP client
D.The DHCP clients of router R2 will receive the same option information that the clients of R1receive

A.The VLAN1-POOL argument must be issued for the Fa0/1 interface on router RTA
B.Router RTA must be configured with the default-router 192.168.3.2 DHCP command.
C.The ip address dhcp interface configuration command must be issued for the Fa0/1 interface ofrouter RTA
D.The ip helper-address 192.168.1.2 interface configuration command must be issued for theFa0/1 interface on router RTA
E.Router RTC must be configured with the ip address dhcp global configuration command
F.The lease 200 DHCP configuration command would change the default DHCP lease time to48 hours on router RTA
