What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?
- A. 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
- B. 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.
- 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 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 will not be triggered because switches cannot run routing protocols between them.

Routers R1 , R2, and R3 are running a classful routing protocol between them. Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3's routing table?
- A. Router R3's routing table can only contain one of the routes, which will result in route flapping.
- B. The networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.
- C. Router R3's routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24.
- D. The networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.
