Question # 34

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

Options:

A.

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.

B.

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.

C.

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

D.

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

E.

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.

Questions # 36:

What is the protocol number for OSPF in the IP header?

Options:

A.

OSPF uses TCP, so the protocol number is 6.

B.

OSPF uses UDP, so the protocol number is 17.

C.

OSPF does not use IP.

D.

OSPF has its own protocol number of 89.

Questions # 37:

Static routing will be used in a network between a corporate head office, with many connected networks, and a branch office, with one connection to the head office. Which of the following best describes the likely configuration?

Options:

A.

The corporate head office router will have a default route and the branch site will have a more specific static route.

B.

The corporate head office router and the branch office router will both have specific static routes.

C.

The corporate head office router and the branch router will both have default routes.

D.

The corporate head office router will have a more specific static route and the branch office router will have a default route.
