ccna 2 final exam version 1 part 4

46. What are two functions of a router? (Choose two.)

It connects multiple IP networks.
It controls the flow of data via the use of Layer 2 addresses.
It determines the best path to send packets.
It manages the VLAN database.
It increases the size of the broadcast domain.

47. Refer to the exhibit. Which statement is true about the routing process for this network?

A packet leaves interface Fa0/0 of R1 with the source MAC address as 000C.3010.9260.
The packet leaves interface Fa0/0 of R1 with the source MAC address as 000C.3010.9260.
The no shutdown command needs to run on the Fa0/0 interface of R1.
The Fa0/0 interface of R2 could be configured with the IP address 172.16.4.1/24.

48. Refer to the exhibit. A network administrator has run the show interface command. The output of this command is displayed. What is the first step that is required to make this interface operational?

Switch the cable with a known working cable.
Issue the no shutdown command on the interface.
Configure the interface as a loopback interface.
Set the encapsulation for the interface.

49. efer to the exhibit. R1 is configured properly for a single area OSPF, and R2 has been recently installed in the network. Which set of commands is required to configure a single area OSPF for the networks that are connected to R2?
R2(config)# router ospf 1
R2(configrouter)# network 192.168.2.0 0.0.0.255 area 0
R2(configrouter)# network 10.1.1.0 0.0.0.3 area 0
R2(config)# router ospf 1
R2(configrouter)# network 192.168.2.0 0.0.0.255 area 0

R2(config)# router ospf 2
R2(configrouter)# network 10.1.1.0 0.0.0.3 area 0
R2(config)# router ospf 1
R2(configrouter)# network 192.168.2.0 0.0.0.255 area 0
R2(configrouter)# network 10.1.1.0 0.0.0.3 area 1
R2(config)# router ospf 1
R2(configrouter)# network 192.168.2.0 0.0.0.255 area 0
R2(configrouter)# network 10.0.0.0 0.0.0.3 area 1

50. Refer to the exhibit. The command ip route 0.0.0.0 0.0.0.0 S0/0/0 is run on router R2. What are the two results of this command? (Choose two.)

A static route will be updated in the routing table.
The traffic from the Internet will be directed to R2.
The traffic from the source network 172.16.0.0/22 will be blocked.
The route will be specified as the default route for all networks not defined in the routing table.
All the broadcasts will be forwarded via the S0/0/0 interface of R2.

51. Which three statements are true regarding the encapsulation and deencapsulation of packets when traveling through a router? (Choose three.)
The router modifies the TTL field, decrementing it by one.

The router changes the source IP to the IP of the exit interface.
The router maintains the same source and destination IP.
The router changes the source physical address to the physical address of the exit interface.
The router changes the destination IP to the IP of the exit interface.
The router sends the packet out all other interfaces, besides the one it entered the router on.

52. What are two tasks that must be completed before two routers can use OSPF to form a neighbor adjacency? (Choose two.)

The routers must elect a designated router.
The routers must agree on the network type.
The routers must use the same dead interval.
The routers must exchange link state requests.
The routers must exchange database description packets.

53. Refer to the exhibit. Although both the routers can ping the serial interface of their neighbors, they are unable to ping the Ethernet interfaces of other routers. Which two statements are true for this network? (Choose two.)

The administrative distance has been set to 50 on both routers.
R2 is learning about network 192.168.1.0.
R1 is learning about network 192.168.2.0.
The network 10.1.1.0 command has not been run on both routers.
Autosummarization is enabled on both routers.

54. Which two situations require the use of a linkstate protocol? (Choose two.)

Fast convergence of the network is critical.
The network is very large.
The network administrator has limited knowledge to configure and troubleshoot routing protocols.The network is a flat network.
The capacity of the router is low.

55. Refer to the exhibit. What information can be determined from the displayed output?

EIGRP packets are waiting to be sent to the neighbors.
The adjacencies between the routers are yet to be established.
The IP address 192.168.10.10 is configured at serial interface S0/0/1 of router R2.
Router R2 is receiving hello packets from a neighbor with the IP address 192.168.10.10 via the R2 S0/0/1 interface.

56. Refer to the exhibit. PC1 is unable to access the Internet. What is the cause of the problem?

An incorrect IP address is configured between the two routers.
No static route is configured on Router2.
A routing loop has occurred.
No routing protocol is configured on either of the two routers.

57. Refer to the exhibit. What summarization should R2 use to advertise its LAN networks to R1?

172.16.0.0/24
172.16.4.0/22
172.16.4.0/23
172.16.4.0/24
