CCNA 2 - Module 7

Refer to the exhibit. If all routers are running RIP version 2, why is there no route for the 192.168.1.32/27 network? Rip version 2 will auto summarize routes by default. Refer to the exhibit. Which two statements are true? (Choose two.) Router1 will install a route to 192.168.0.0/20 Router2 will not install a route to 192.168.16.0/20 Refer to the exhibit. Which command on which router will allow Router1 to learn about the 192.168.0.0/20 network? Router2(config-router)# version 2 What are two reasons to implement RIP version 2 rather than RIP version 1? (Choose two.) RIP version 2 supports VLSM. RIP version 2 supports routing update authentication. How are RIP v1 and RIP v2 similar to one another? (Choose three.) They both use hop count as a metric. They both have the same metric value for infinite distance. They both use split horizon to prevent routing loops. Refer to the exhibit. Routers East and West are configured using RIPv1. Both routers are sending updates about their directly

Refer to the exhibit. What can be determined from this output? All of the routes listed are network routes. Refer to the exhibit. A packet destined for host 128.107.0.5/16 is processed by the JAX router. After finding the static route in the routing table that matches the destination network for this packet, what does the router do next? performs a recursive lookup to find the exit interface used to forward the packet Refer to the exhibit. What parent network will automatically be included in the routing table when the three subnets are configured on Router1? 172.16.0.0/16 The following entry is displayed in the routing table: R 192.168.8.0/24 [120/2] via 192.168.4.1, 00:00:26, Serial0/0/1 What type of route is this? a level 1 ultimate network route Refer to the exhibit. Router1 is running IOS version 12.2. What will the network administrator need to do so that packets for unknown child routes of 172.16.0.0/24 will not be dropped? do nothing, ip classless is on by default Refer to the

CCNA 2 - Module 9

On a router running EIGRP, what database would maintain a list of feasible successors? topology table Refer to the exhibit. This is the debug output from 2 directly connected EIGRP routers. They are not forming an adjacency. What is the cause? network 192.168.1.64 0.0.0.3 What two actions will the EIGRP DUAL FSM take if a link to a network goes down? (Choose two.) query neighbors for a new route s earch topology table for a feasible successor Refer to the exhibit. What is indicated by the P at the beginning of the topology entry? the route is in a stable state In which of the following tables does the EIGRP DUAL algorithm store the primary route to a destination? (Choose two.) routing topology What information is maintained in the EIGRP topology database for a destination route? (Choose three.) the routing protocol the feasible distance of the route the route cost as advertised by the neighboring router Which of the following statements describes the bounded updates used by

CCNA 2 - Module 10

Refer to the exhibit. When Router D is configured to use a link-state routing protocol and is added to the network, what is the first thing that it does to begin learning the network topology? It learns about its directly connected networks when its interfaces reach the up state. What two events will cause a link state router to send LSPs to all neighbors? (Choose two.) whenever the network topology changes upon initial startup of router or routing protocol What is the final step in the link state routing process? SPF computes best path to each destination network What two statements correctly describe the link state routing process? (Choose two.) each router in the area floods LSPs to all neighbors all routers in the area have identical link state databases Refer to the exhibit. What kind of information would be seen in an LSP sent from router JAX to router ATL? cost of the link What feature do modern link-state protocols provide to minimize processing and memory requirement

CCNA 2 - Module 11

1 Refer to the exhibit. What does the "O*E2" from the "O*E2 0.0.0.0/0 [110/1] via 192.168.1.1, 00:05:34, Serial0/0" line represent? an external OSPF route that will not increment in cost. Refer to the exhibit. What is the cost of the route to the 10.0.0.0 network? 1786 What three parameters must be indentical between OSPF routers in order to form an adjacency? (Choose three.) area id hello interval network type What does OSPF use to reduce the number of exchanges of routing information in networks where large numbers of neighbors are present? (Choose two.) designated router backup designated router What does OSPF use to calculate the cost to a destination network? bandwidth A fully converged five router OSPF network has been running successfully for several weeks. All configurations have been saved and no static routes are used. If one router looses power and reboots, what information will be in its routing table after the configuration file is loaded but before O
