A. ping 10.5.5.5

B. ping static 0.0.0.0/0

C. ping static 10.5.5.5

D. ping 0.0.0.0

A. A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.

B. A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

C. A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

D. A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

A. Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

B. Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

C. Manual route summarization can only be done on autonomous system border routers.

D. Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

A. One

B. Three

C. Two

D. Four

A. traceroute next-hop 10.1.2.1

B. traceroute 10.1.2.1

C. traceroute 10.2.3.1 next-hop 10.1.2.1

D. traceroute 10.2.3.1

E. traceroute does not work on the Nokia 7750 SR.

A. The link state information already in the database is overwritten and the age is reset

B. The link state information is not populated in the database but is forwarded to all neighbors

C. The link state information is not populated in the database and an acknowledgement is sent

D. The link state information is regarded as old and nothing is done.

A. Router ID not defined

B. Different metric set on each end of the link

C. Area ID not the same

D. MTU mismatch

E. Incorrect subnet mask

F. System interface not included in OSPF

A. 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.

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

D. 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.

E. 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.

A. Priority of 0

B. Priority of 255

C. Priority of 1

D. Priority of 64

A. The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

B. The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.

C. The adjacency state is two way because both routers have received a database description packet.

D. The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.
