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.

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2? （）A. Add the area 1 stub command on routers R1.B. Add the always keyword to the default - information originate configuration command on router R2.C. Remov e the default information originate configuration command from router R2 and place it on router R1.D. Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.
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 1B. The subnets keyword was not included in the redistribute command under router ospf 1C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router AD. The default - information originate command needs to be added under router ospf 1E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF
