Nokia OSPF Routing Protocol Sample Questions:

Question #1
Click the exhibit button.

What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

A. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
B. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
C. Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
D. Convergence will not be triggered because switches cannot run routing protocols between them.
E. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

Question #2
Which of the following statements regarding area border routers in an OSPF network is true?

A. Area border routers connect the backbone area to other areas in an OSPF network.
B. An OSPF network needs at least one area border router to function.
C. The term backbone router has the same definition as the term area border router.
D. By definition, an area border router must perform route summarization between areas.

Question #3
In an OSPF Hello packet what fields must match all neighbor routers on the segment? (Choose 3)

A. Stub flag
B. Hello and Dead Intervals
C. Area ID
D. DR and BDR addresses
E. The list of neighbors

Question #4
Which of the following statements best describes an OSPF type 3 LSA?

A. An OSPF type 3 LSA is an inter-area LSA, generated by the ABR only when route summarization is configured.
B. An OSPF type 3 LSA is an intra-area LSA, generated by the ABR only when route summarization is configured.
C. An OSPF type 3 LSA is an inter-area LSA, generated by an ASBR to describe external routes.
D. An OSPF type 3 LSA is an inter-area LSA, generated by the ABR to describe a route to neighbors outside the area.

Question #5
Which of the following is NOT a characteristic of RIPv1?

A. 30 second network updates
B. Broadcast advertisement
C. Classless routing
D. Poison Reverse
