Refer to the exhibit. A network administrator has configured DHCP services on the router asshown. DHCP clients connected to the FastEthernet0/0 interface are working properly. DHCP clients connected to the FastEthernet0/1 interface are not receiving addresses.
Which two statements contain recommendations that will solve the problem?（）
A.The network shown in the output under the ip dhcp pool Central command should be changed to 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 be issued
D.The ip helper -address 10.0.0.1 command should be issued so that the address can be added to the Fast Ethernet0/0 c onfiguration

Refer to the exhibit. EIGRP had converged in AS 1 when the link between router R1 and R2 went down. The console on router R2 generated the following messages:
*Mar 20 12:12:06: %DUAL - 5NBRCHANG E: IP - EIGRP 1: Neighbor 10.1.4.3 (Serial0) is down: stuck in active
*Mar 20 12:15:23: %DUAL -3- SIA: Route 10.1.1.0/24 stuck - in - active state in IP - EIGRP 1.
Cleaning up The network administrator issued the show ip eigrp topology active command on R2 to check the status of the EIGRP network.
Which statement best describes the reason for the error messages?（）
A. Incorrect bandwidth configuration on router R3 prevents R2 from establishing neighbor adjacency.
