C. The update will be ignored and thus no further action will occur.
D. The existing routing table entry will be purged from the routing table and all routers will attempt convergence.

A RIP router has an entry in the routing table for a specific network destination. It then gets updated with another entry for that same destination, but with a higher path cost (hop count) than the one already in the routing table.
What will the router do in this situation?（）
A. It will ignore the update and take no further action.
B. It will add the update information to its routing table.
C. It will replace the existing routing table entry with the update information.
D. It will delete the existing routing table and will send out hello packets to rebuild the routing table.
The Testking network is utilizing RIP as the IP routing protocol. Router TK1 learns how to reach the same destination via 6 different paths. All paths have the same metric and administrative distance.
With all routers using the default operation,which of the paths will be chosen to reach the destination?（）
A. Only the first two paths that are learned.
B. Four of the paths.
C. All six routes in a routed robin fashion.
D. The oldest two paths in the routing table.
E. The first path learned to the destination network.
A. Discontiguous subnets are not allowed.
B. Variable length subnet masks are allowed.
C. RIP v1 is a classless routing protocol.
D. IGRP supports classless routing within the same autonomous system.
E. RIP v2 supports classless routing.
A. Only routers can split boundaries (horizons) between concentric networks.
B. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.
C. Networks can only remain fully converged if all information is sent out all active interfaces.
D. Information about a route should not be sent back in the direction from which the original update came.
E. Distance vector protocols need fall back routers that are responsible for momentary loops.
A. SPF packets
B. hello packets
C. keepalive packets
D. dead interval packets
E. LSU packets
A. LSAs from other routers
B. Beacons received on point-to-point links
