1.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.

2.Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.

3.Which command enables OSPF for IPv6?()A. router ospf ipv6 process - idB. ipv6 ospf process - idC. router ospf process - idD. ipv6 router ospf process - id

4.The administrator wants to verify the current state of the OSPF database loading process. Which show command should the administrator use?()A. show ip ospf [process - id] interfaceB. show ip ospf neighborC. show ip ospf [process - id]D. show ip ospf [process - id area - id] database
