To achieve this, you are considering deploying a Cisco Nonstop Forwarding with Stateful Switchover solution using OSPF.In the exhibit you can see the output of the show ip ospf neighbor detail command.Which trait of systems using Cisco Nonstop Forwarding with Stateful Switchover and OSPF is shown in the exhibit output and will impact your plan?（）
A. Stateful Switchover for Cisco Nonstop Forwarding only works with BGP.
B. Stateful Switchover for Cisco Nonstop Forwarding must be configured on all adjacent routers.
C. Cisco Nonstop Forwarding with Stateful Switchover helper mode is not supported on the adjacent router.
D. Cisco Nonstop Forwarding with Stateful Switchover helper mode for OSPF has been promiscuousstandardized and is supported on the adjacent router.

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.

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.
