NEW QUESTION 44
Click the exhibit button.

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

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.

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.

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

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.

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.

What can you deduce from the show command on router R6?

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment.
The DR for this segment would be the router with router ID 10.10.10.5.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.

The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment.The DR for this segment would be the router with router ID 10.10.10.3.
