    Refer to the exhibit. You are the network administrator responsible for the NProuter, the 10.1.1.1 router, and the 10.1.1.2 router. What can you determine about the OSPF operations from the debug output?
    NProuter#debug ip ospf events

    OSPF events debugging is on

    NProuter#
    00:02:03: OSPF: Rev hello from 172.16.1.1 area 0 from Serial0/0 10.1.1.1
    00:02:03: OSPF: Mismatched hello parameters from 10.1.1.1
    00:02:03: OSPF: Dead R 120 C 10, Hello R 30 C 30
    00:02:26: OSPF: Rev hello from 192.168.1.2 area 0 from Serial0/0 10.1.1.2
    00:02:26: OSPF: Mismatched hello parameters from 10.1.1.2
    00:02:26: OSPF: Dead R 120 C 10, Hello R 30 C 30

    A. The NProuter has two OSPF neighbors in the "Full" adjacency state.
    B. The NProuter serial0/0 interface has the OSPF dead timer set to 10 seconds.
    C. The NProuter serial0/0 interface has been configured with an OSPF network type of "point-to-point".
    D. The 10.1.1.1 and 10.1.1.2 routers are not using the default OSPF dead and hello timers setting.
    E. The "Mismatched" error is caused by the expiration of the OSPF timers. 8)
