Which three route filtering statements are true?() A. After the router ospf 10 and passive - interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interfaceB. When you use the passive - interface command with RIPv2, multicasts are sent out the specified interfaceC. After the router rip and passive -interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interfaceD. When you use the passive - interface command with EIGRP, hel lo messages are not sent out the specified interfaceE. After the router eigrp 10 and passive - interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interfaceF. When you use the passive - interface command with OSPF, hello messages are not sent out the specified interface
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. 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.
