Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）
A. The no auto - summary command needs to be added under router eigrp 1
B. The subnets keyword was not included in the redistribute command under router ospf 1
C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router A
D. The default - information originate command needs to be added under router ospf 1
E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF

Refer to the exhibit. Router B is performing bidirectional redistribution between EIGRP an d OSPF.The network 10.100.1.0/24 should not be reachable from the 10.100.9.0/24 network. However, it needs to be reachable from any network within the EIGRP domain. All other networks should be seen in both domains. Which change to router B would accom plish these goals?（）
A. Under the EIGRP process, insert the distribute - list block_net_1 out ospf 1 command.
B. Under the OSPF process, insert the distribute - list block_net_1 in serial1/0 command.
C. Under the EIGRP process, insert the distribute - list block_net_1 in serial1/0 command.
D. Under the OSPF process, insert the distribute - list block_net_1 out eigrp 1 command.
Refer to the exhibit. AS 65500 is not advertising the prefix 192.168.12.0/22 to its provider. AS 65500 is running OSPF as its IGP. Whi ch of the following additions to the configuration is most likely to solve the problem?（）
A. RouterA(config)#ip cef
B. RouterA(config)#ip route 192.168.12.0 255.255.255.252 null 0
C. RouterA(config - router)#ebgp multihop 1
D. RouterA(config - router)#re distribute ospf 1
E. RouterA(config - router)#neighbor 192.168.14.253 next - hop - self
F. RouterA(config - router)#neighbor 192.168.14.253 local - as 65500

What can be done to fix the problem?（）
A. Change router B E0/1 interface to area 0.
B. Change router A interface E0/1 to area 0.0.0.2.
C. Configure the E0/1 i nterfaces of router A and router B to be in area 0.
D. Shut down the E0/1 interfaces in router A and router B as OSPF does not allow "back doors" between areas.
E. Remove the E0/1 interfaces in router A and router B from the OSPF process. Use static rou tes to route data directly from router A to router B to avoid passing data through router C in area 0.
Refer to the exhibit. Router C was configured so that it could form an adja cency with three OSPF neighbors, one connected to each of its three physical interfaces. Which statement is correct about router C?（）
A. It is configured and functioning correctly as an OSPF internal router.
B. It is configured and functioning correc tly as an ABR attached to stub area 4.
C. It is configured and functioning correctly as an ASBR attached to external area 4.
D. It is configured and functioning correctly as an ABR attached to totally stubby area 4.
E. It is not configured correctly to function as specified.
A. Apply the area 4 stub command to all routers in the area
B. On the ABR, use the area 4 stub command with the no - summary keyword
C. On the ABR, specify a default cost for the area with the area default - cost command
D. On the ABR, use the default - information originate command to inject a default route into area 4
E. Use the auto - cost command on each router in the area to automatically determine the cost to other OSPF areas
