10 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

11 Which statements describe RIP? (Choose three.)
• The maximum metric value is 255 hops.
• The maximum metric value is 15 hops.
• Routing updates occur every 30 seconds.
• Routing updates occur every 90 seconds.
• It is a distance vector routing protocol.
• It is a link state routing protocol.

12 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.

13

The administrator of the network depicted in the graphic would like to decrease the network's convergence time. How can this be accomplished?
• disable split horizon on the routers
• increase the update interval on the routers
• change the RIP holddown timer to 96 seconds
• change the RIP holddown timer to 226 seconds

14

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.

15 Which statements describe load balancing when RIP is configured as the routing protocol? (Choose two.)
• A router is allowed to take advantage of multiple best paths to a given destination.
• RIP uses the round robin approach in load balancing.
• RIP load balancing selects a single path to forward all data to the destination even though equal parallel paths exist.
• RIP load balancing is based on bandwidth first and then the hop count.
• Only one path to a destination can be statically assigned or dynamically calculated.

16

The graphic shows a network that is configured to use RIP routing protocol. Router2 detects that the link to Router1 has gone down. It then advertises the network for this link with a hop count metric of 16. Which routing loop prevention mechanism is in effect?
• split horizon
• error condition
• hold-down timer
• route poisoning
• count to infinity

17

• 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.

19 The following line was displayed in the output of the show ip route command:
192.168.3.0/24 [120/2] via 192.168.2.2, 00:00:30, Serial0/0

22 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.
