6. PRACTICE TEST + QUESTION AND ANSWERS PDF What trinners convernence of the routnn protocol when the link between switch 1 and switch 2 noes down? A. Convernence is trinnered when the adjacency between routers R1 and R2 drops as a result of Hello tmeouts. 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 converned. B. Convernence is trinnered when the physical interfaces between routers R1 and R2 no 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 converned. C. Convernence will not be trinnered because switches cannot run routnn protocols between them. D. Convernence is trinnered when the switches notfy the routers about the link state informaton. 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 converned E. Convernence is trinnered 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 converned.

The router R6 interface is in a mult-access senment. It is neither the DR nor the BDR for the senment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR. C. The router R6 interface is in a mult-access senment. It is the BDR, which is why it is not adjacent to the other routers. D. The router R6 interface is in a mult-access senment. It is neither the DR nor the BDR for the senment. The DR for this senment would be the router with router ID 10.10.10.3. Aoswern B Question 18 Click the exhibit buton. Page | 7 Page | 7
