Exhibit

Given the two configurations shown, identify the two incorrect statements below: (Choose two)

A. The system interface is missing in one configuration so OSPF will not operate correctly.

B. Both routers will generate OSPF Hello packets.

C. Metric values differ, but this does not prevent OSPF operation.

D. The interface type settings differ, but OSPF will still operate correctly.

質問 2

When are virtual links used in OSPF?

A. When an area needs to connect directly to another area without using area 0.

B. When two areas are connected to area 0, but there is no direct path between them.

C. When an area needs to traverse another area to reach area 0.

D. When two areas need to communicate and there is no area 0.

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

C. 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.

D. 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.

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.
