OSPF is enabled on router A. You execute the following command on router A and receive theaccompanying output:RouterA#ping 224.0.0.5 repeat1Type escape sequence to abort.Sending 1, 1 00 - byte ICMP Echos to 224.0.0.5, timeout is 2 seconds:Reply to request 0 from 10.100.100.1, 4 ms10.100.100.1 is the IP address of a loopback interface on router A.
What can you conclude about router A?（）
A. Only the router A loopback interface is parti cipating in the OSPF routing process
B. None of the router A interfaces are participating in the OSPF routing process
C. Router A is using the loopback interface IP address as its OSPF router ID
D. Router A does not have any reachable OSPF neighbors
Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running - configuration command output? （）
A. The OSPF areas are not configured correctly.
B. The wildcard masks for the 10.x .x.x networks are incorrect.
C. The 172.16.x.x networks need to be connected to area 0 using virtual links.
D. The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being "black holed."
E. There is not enough information to make a determination.
Refer to the exhibits. Router B should advertise the network co nnected to the E0/0/0 interface to router A and block all other network advertisements. The IP routing table on router A indicates that it is not receiving this prefix from router B. What is the probable cause of the problem?（）
A. An access list on router B is causing the 192.168.3.16/28 network to be denied
B. An access list on router B is causing the 192.168.3.32/28 network to be denied
C. The distribute list on router B is referencing a numbered access list that does not exist on router B
D. The d istribute list on router B is referencing the wrong interface
