Question 695. What is split horizon?

It holds the regular updates from broadcasting to a downed link.
It prevents regular update messages from reinstating a route that has gone down.
Information about a route should not be sent back in the direction from which the original update came.

Question 696. Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?

The updated information will replace the existing routing table entry.
The update will be ignored and no further action will occur.
The updated information will be added to the existing routing table.
They will all load-balance.
The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence.

Discuss Question

Answer: Option B. -> The update will be ignored and no further action will occur.

Question 699. The Corporate router receives an IP packet with a source IP address of 192.168.214.20 and a destination address of 192.168.22.3. Looking at the output from the Corporate router, what will the router do with this packet?Corp#sh ip route[output cut]R 192.168.215.0 [120/2] via 192.168.20.2, 00:00:23, Serial0/0R 192.168.115.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0R 192.168.30.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0C 192.168.20.0 is directly connected, Serial0/0C 192.168.214.0 is directly connected, FastEthernet0/0

The packet will be routed out the Fa0/0 interface.
The packet will be discarded.
They will all load-balance.
The router will broadcast looking for the destination.
The packet will be routed out the S0/0 interface.

Discuss Question

Answer: Option B. -> The packet will be discarded.
