19. Refer to the exhibit. A network administrator successfully pings R1 from R3. Next, the administrator runs the show cdp neighbors command on R3. The output of this command is displayed.What are two reasons for the absence of R1 in the output? (Choose two.)

There is a Layer 2 connectivity problem between R1 and R3.
The Fa0/0 interface of R1 is configured with an incorrect IP address.
The no cdp run command has been run at R1.
The no cdp enable command has been run at Fa0/1 interface of R3.R1 is powered off.

20. Refer to the exhibit. A device is required to complete the connection between router R1 and the WAN. Which two devices can be used for this? (Choose two.)

a CSU/DSU device
a modem
an Ethernet switch
a hub
a bridge

21. In a complex lab test environment, a router has discovered four paths to 192.168.1.0/24 via the use of the RIP routing process. Which route will be installed in the routing table after the discovery of all four paths?

R 192.168.1.0/24 [120/3] via 192.168.110.1, 00:00:17, Serial 0/1/0
R 192.168.1.0/24 [120/2] via 192.168.200.1, 00:00:17, Serial 0/0/0
R 192.168.1.0/24 [120/1] via 192.168.100.1, 00:00:17, Serial 0/0/1
R 192.168.1.0/24 [120/4] via 192.168.101.1, 00:00:17, Serial 0/1/1

22. Refer to the exhibit. A network administrator accesses router R1 from the console port to configure a newly connected interface. What passwords will the network administrator need to enter to make the connection and the necessary configuration changes?

the Cisco123 password only
the Cisco789 password only
the Cisco001 password only
the Cisco001 password and the Cisco789 passwords
the Cisco001 password and the Cisco123 passwords

23. Refer to the exhibit. A network administrator adds this command to router R1: ip route 192.168.2.0 255.255.255.0 S0/0/0. What is the result of adding this command?

This route is automatically propagated throughout the network.
The traffic for network 172.16.1.0 is forwarded to network 192.168.2.0.
A static route is established.
The traffic for all Class C networks is forwarded to 172.16.1.2.

24. Refer to the exhibit. The router receives a packet that is destined for 192.168.5.79. How will the router handle this packet?

It will forward the packet via the Serial0/0/1 interface.
It will forward the packet via the FastEthernet0/0 interface.
It will forward the packet via the Serial0/0/0 interface.
It will drop the packet.

25. Which two statements are true about classless routing protocols? (Choose two.)
They can be used for discontiguous subnets.
They can forward supernet routes in routing updates.
They cannot implement classful routes in routing tables.
They use only a hop count metric.
They do not include the subnet mask in routing updates.

26. Refer to the exhibit. How many routes are child routes?
1
3
4
6

27. A router has EIGRP configured as the only routing protocol. In what two ways does EIGRP respond if there is no feasible successor route to a destination network and the successor route fails? (Choose two.)
It broadcasts hello packets to all routers in the network to reestablish neighbor adjacencies.
It sends queries to adjacent neighbors until a new successor route is found.
It immediately sends its entire routing table to its neighbors.
It sends queries to adjacent neighbors until the lost route is unknown to the neighbors.
It automatically forwards traffic to a fallback default route until a successor route is found.

28. 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

29. Refer to the exhibit. Which two statements are true based on the exhibited output? (Choose two.)

The administrative distance of EIGRP has been set to 50.
All routes are stable.
The show ip eigrp topology command has been run on R1.
The serial interface between the two routers is down.
Each route has one feasible successor.

30. Refer to the exhibit. All routers are properly configured with default configurations and are running the OSPF routing protocol. The network is fully converged. A host on the 192.168.3.0/24 network is communicating with a host on the 192.168.2.0/24 network. Which path will be used to transmit the data?

The data will be transmitted via R3-R2.
The data will be transmitted via R3-R1-R2.
The traffic will be loadbalanced between two paths — one via R3-R2, and the other via R3-R1-R2.
The data will be transmitted via R3-R2, and the other path via R3-R1-R2 will be retained as the backup path.
