CCNA 2 Final Exam Answers 2011

1. Refer to the exhibit. The show cdp neighbors command was run at R1. Which two facts about the newly detected device can be determined from the output? (Choose two.)

ABCD is a router that is connected to R1.

ABCD is a non-CISCO device that is connected to R1.

The device is connected at the Serial0/0/1 interface of R1.

R1 is connected at the S0/0/1 interface of device ABCD.

ABCD does not support switching capability.

 

2. Refer to the exhibit. Packets destined to which two networks will require the router to perform a recursive lookup? (Choose two.)

10.0.0.0/8

64.100.0.0/16

128.107.0.0/16

172.16.40.0/24

192.168.1.0/24

192.168.2.0/24

 

3. Refer to the exhibit. The output of the show ip route command for router R1 is displayed. What action will the router take for a packet that is destined for 192.168.1.5?

It will drop the packet.

It will forward the packet to interface Serial0/0/0.

It will determine the route for the packet through a routing protocol.

It will forward the packet to the default gateway.

1. Refer to the exhibit. The output of the show ip route command for three routers on a network is displayed. All routers are operational, pings are not blocked on this network, and no default routes are installed. Which two pings will fail? (Choose two.)

from R1 to 172.16.1.1

** from R1 to 192.168.3.1

from R2 to 192.168.1.1

from R2 to 192.168.3.1

** from R3 to 192.168.1.1

 

2. A router that uses the RIP routing protocol has an entry for a network in the routing table. It then receives an update with another entry for the same destination network but with a lower hop count. What action will the router take for this new update?

** It will append the update information to the routing table.

It will invalidate the entry for that network in the routing table.

It will replace the existing routing table entry with the new information.

It will ignore the new update.

 

3. Which two statements are true for OSPF Hello packets? (Choose two.)

They negotiate correct parameters among neighboring interfaces.

They are used for dynamic neighbor discovery.

They use timers to elect the designated router with the fastest link.

** They are received from all routers on the network and used to determine the complete network topology.

** They are used to maintain neighbor relationships.

 

4. A network administrator needs to configure a single router to loadbalance the traffic over unequal cost paths. Which routing protocol should the administrator use?

EIGRP

OSPF

RIPv1

** RIPv2

 

5. Which two statements are correct about the split horizon with poison reverse method of routing loop prevention? (Choose two.)

It is enabled by default on all Cisco IOS implementations.

** It assigns a value that represents an infinite metric to the poisoned route.

** It sends back the poisoned route update to the same interface from where it was received.

It instructs routers to hold all changes that might affect routes, for a specified period of time.

It limits the number of hops a packet can traverse through the network before it is discarded.

1. Refer to the exhibit. A new PC was deployed in the Sales network. It was given the host address of 192.168.10.31 with a default gateway of 192.168.10.17. The PC is not communicating with the network properly. What is the cause?

The address is in the wrong subnet.

***192.168.10.31 is the broadcast address for this subnet.

The default gateway is incorrect.

The host address and default gateway are swapped.

 

2. Refer to the routing table shown in the exhibit. What is the meaning of the highlighted value 192?

It is the value assigned by the Dijkstra algorithm that designates the number of hops in the network.

It is the value used by the DUAL algorithm to determine the bandwidth for the link.

***It is the metric, which is cost.

It is the administrative distance.

 

3. Refer to exhibit. Given the topology shown in the exhibit, what three commands are needed to configure EIGRP on the Paris router? (Choose three.)

***Paris(config)# router eigrp 100

Paris(config)# router eigrp

Paris(configrouter)# network 192.168.6.0

***Paris(configrouter)# network 192.168.7.0

***Paris(configrouter)# network 192.168.8.0

Paris(configrouter)# network 192.168.9.0

 

4. What are three features of CDP? (Choose three.)

***tests Layer 2 connectivity

provides a layer of security

operates a OSI layers 2 and 3

***enabled by default on each interface

used for debugging Layer 4 connectivity issues

***provides information on directly connected devices that have CDP enabled

 

5. Refer to the exhibit. What two statements are true based on the output shown? (Choose two.)

the reported distance to network 172.16.1.0 is 2172416

192.168.10.5 and 192.168.10.9 are feasible successors

***neighbors 192.168.10.9 and 192.168.10.5 have auto summary disabled.

***router 3 is load balancing traffic to the 172.16.3.0 network across its serial interfaces.

all interfaces shown on Router3 are in the passive state and will not send EIGRP advertisements
