Which of the following statements regarding IS-IS DIS is false?

A. L1 and L2 routers elect separate DIS's.

B. DIS uses multicast address 0180x200:0015 to communicate with other routers on the broadcast network.

C. If a new router starts up in a LAN and has a higher interface priority, the new router preempts the original DIS and becomes the DIS.

D. In broadcast multi-access networks, such as Ethernet, a single router is elected as the DIS. There is no backup DIS

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

A. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of hello timeouts.

B. Convergence is triggered when the physical interfaces between routers R1 and R2 go down.

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 info.

E. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down.
