| Which of the following methods does split horizon use to reduce
incorrect routing information? | |
| Routing updates are split in half to reduce the update time. | |
| Information learned from one source is not distributed back to that source. | |
| New route information must be learned from multiple sources to be accepted. | |
| The time between updates is split in half to speed convergence. | |
| New route information is suppressed until the system has converged | |
| When does a distance vector routing protocol set a hold-down timer
on a route? | |
| when the metric value of the route decreases | |
| when the route is marked as inaccessible | |
| when the metric value for the route improves | |
| when a regular update is received from a neighboring router | |
| Which of the following functions are performed by a router as
routing information travels through the network? (Choose two.) | |
| advertise supported applications | |
| identify new destinations | |
| calculate packet speed | |
| verify network scalability | |
| identify invalid networks | |
| Which command or set of commands will stop the RIP routing
process? | |
| RouterB(config)# router rip
RouterB(config-router)# shutdown | |
| RouterB(config)# router rip
RouterB(config-router)# network no 192.168.2.0 | |
| RouterB(config)# no router rip | |
| RouterB(config)# router no rip | |
| Which command will display RIP activity as it occurs on a router?
| |
| debug ip rip | |
| show ip route | |
| show ip interface | |
| show ip protocols | |
| debug ip rip config | |
| show ip rip database | |
| How would an administrator configure a static route for use if a
primary route failed? | |
| configure the route with a metric greater than the default value | |
| configure the route and the router will activate it as needed | |
| configure the route to activate by using the redistribute static command | |
| configure the route with an administrative distance greater than the default value | |

| When a routing table update is received by a router in a distance
vector network, which of the following occurs? | |
| The hop count metrics for the enclosed routes are incremented. | |
| The update is forwarded to the gateway router for verification. | |
| Path entries are checked for routing loops. | |
| The hop count metrics for the enclosed routes are decremented. | |
| Static routes are updated with the new information. | |
| A router has routes to several subnets of a classful network in
its routing table. A default route is defined on the router but the ip
classless command is disabled. If the router receives packets for a subnet
that is not in its routing table but is in the same classful network as the
other subnets, what will happen to the packets? | |
| The packets will be forwarded using the default route. | |
| The packets will be forwarded using a route to one of the other subnets of the classful network. | |
| A nonreachable message will be returned to the source. | |
| The packets will be discarded. | |
| The router will generate a new route to the subnetted network. | |
| According to the router output from the show ip route command shown
above, which of the following statements are true? (Choose two.) | |
| The metric to network 192.168.8.0 is 24. | |
| The hop count to a device on network 192.168.8.0 is 2. | |
| The total path cost to network 192.168.4.0 is the default value of 16. | |
| The logical address of the next router for network 192.168.1.0 is 192.168.3.1. | |
| The devices on network 192.168.5.0 cannot be reached as indicated by the 'C' label. | |
| What happens to a static route entry in a routing table when the
outgoing interface is not available? | |
| The route is removed from the table. | |
| The router polls neighbors for a replacement route. | |
| The route remains in the table because it was defined as static. | |
| The router redirects the static route to compensate for the loss of the next hop device. | |

| When does RIP send routing table updates? (Choose two.)
| |
| periodically, every 30 seconds | |
| periodically, every 60 seconds | |
| periodically, every 90 seconds | |
| if optionally configured, when topology changes occur (triggered-update) | |
![]() If the passive interface command is enabled on the fa0/0 interface of Router E, which statements are true? (Choose two.) | |
| Router E will send all routing updates via interface fa0/0. | |
| Router E will ignore all routing updates learned via interface fa0/0. | |
| Router E will use routing updates learned via interface fa0/0. | |
| Router E will not send routing updates via interface fa0/0. | |

| What do distance vector algorithms require each router in the
network to send? | |
| a partial routing table to each router in the LAN | |
| a partial routing table to each router in the WAN | |
| the entire routing table to each neighboring router | |
| the entire routing table to each router in the autonomous system | |
