Free Nokia OSPF Routing Protocol Exam Practice Questions

A.  

Not so stubby areas

B.  

Level1 area WC

C.  

Stub areas

D.  

Partially stubby areas

E.  

Level 2 areas

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.  

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.  

From the last 32 bits of the chassis MAC address

B.  

From the first 32 bits of the chassis MAC address

C.  

The loopback IP address

D.  

By using the command "config router ospf router-id X.X.X.X"

E.  

From the system IP address

F.  

From the highest interface IP address

A.  

They are type 7 within the area and are not modified at the ABR

B.  

They are type 5 within the area and converted to type 3 at the ABR

C.  

They are type 5 within the area and are not modified at the ABR

D.  

They are type 7 within the area and converted to type 5 at the ABR

A.  

RIPv1 and RIPv2

B.  

OSPF

C.  

IS-IS

D.  

BGP

A.  

The protocol field of the transport layer header

B.  

The port field of the transport layer header

C.  

The protocol field of the network layer header

D.  

The port field of the network layer address

A.  

configure router static-route 139.120.121.0/24 next-hop 138.120.199.2

B.  

configure router static-route 139.120.121.0/24 next-hop 138.120.199.1

C.  

configure router static-route 138.120.199.2/24 next-hop 138.120.199.1

D.  

configure router static-route 139.120.121.0/24 next-hop 139.120.121.2

A.  

224.0.0.5

B.  

224.0.0.6

C.  

The unicast IP address of the interface the update is being sent on.

D.  

The system address of the router

A.  

The prefix list reject should be "192.168.3.0/16 exact".

B.  

Router R1 should be configured as an OSPF "asbr".

C.  

The policy "reject" should be set for import rather than export.

D.  

The policy was likely not "committed" after creation.

E.  

This is not possible because OSPF cannot use import policies.
