4A0-113 Dumps - Nokia OSPF Routing Protocol Exam Practice Exam Questions

A.  

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.

B.  

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.

C.  

Convergence will not be triggered because switches cannot run routing protocols between them.

D.  

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.

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.

A.  

The age for newly created link state information is set to 0 for OSPF and 1200 for IS-IS

B.  

The age for newly created link state information is set to 1200 for OSPF and 0 for IS-IS

C.  

The age is incremented or decremented as it is flooded from router to router and as it is held in the topological database.

D.  

The age is incremented or decremented only as it is held in the topological database and not as it is flooded router to router.

A.  

Not so stubby areas

B.  

Level1 area WC

C.  

Stub areas

D.  

Partially stubby areas

E.  

Level 2 areas
