output from the exhibit, what is the most likely cause of the problem?

o The command default-information originate has not been issued on R1.o There are no EIGRP neighbor relationships on R1.o The ip route command must specify a next-hop IP address instead of an exit interface

when creating a default route.o The command redistribute static has not been issued on R1.o The network statement for the ISP connection has not been issued.

o ip bandwidth-percent eigrp 100 48o ip bandwidth-percent eigrp 64 48o ip bandwidth-percent eigrp 100 64o ip bandwidth-percent eigrp 100 75o ip bandwidth-percent eigrp 75 100

12. Refer to the exhibit. A network administrator has issued the shown commands. The EIGRP routing domain has completely converged and a network administrator is planning on configuring EIGRP authentication throughout the complete network. On which two interfaces should

www.ccna5answers.com www.ccna5blog.com www.ccna-5.com

EIGRP authentication be configured between R2 and R3? (Choose two.)

o serial 0/0/1 of R2o serial 0/1/0 of R2o gig 0/0 of R3o serial 0/0/1 of R3o serial 0/1/0 of R4

13. Refer to the exhibit. A network administrator has configured EIGRP authentication between routers R1 and R2. After the routing tables are reviewed, it is noted that neither router is receiving EIGRP updates.

www.ccna5answers.com 7

8

What is a possible cause for this failure?

o The same key chain name must be used on each router.o The same number of key strings must be used on each router.o The key string should be used in interface mode instead of the key chain.o The same autonomous system numbers must be used in the interface configurations

of each router.o The authentication configuration is correct, issue the show ip eigrp neighbors

command to troubleshoot the issue.14. Two routers, R1 and R2, have established an EIGRP neighbor

relationship, but there is still a connectivity problem. Which issue could be causing this problem?​

o an authentication mismatcho an access list that is blocking advertisements from other networkso automatic summarization that is disabled on both routerso a process ID mismatch

15. Refer to the exhibit. Remote users are experiencing connectivity problems when attempting to reach hosts in the 172.21.100.0 /24 network. Using the output in the exhibit, what is the most likely cause of the connectivity

www.ccna5answers.com www.ccna5blog.com www.ccna-5.com

problem?

o The passive-interface command is preventing neighbor relationships on interface GigabitEthernet 0/0.

o The hello timer has been modified on interface GigabitEthernet 0/1 of R3 and not on the neighbor, causing a neighbor adjacency not to form.

o The GigabitEthernet 0/1 interface is not participating in the EIGRP process.o The GigabitEthernet interfaces are not limiting the flow of EIGRP message

information and are being flooded with EIGRP traffic.16. Refer to the exhibit. After the configuration shown is applied on router

R1, the exhibited status message is displayed. Router R1 is unable to form a neighbor relationship with R2 on the serial 0/1/0 interface. What is the

www.ccna5answers.com 9

10

most likely cause of this problem?

o The passive-interface command should have been issued on serial 0/1/0.o The hello interval has been altered on serial 0/1/0 and is preventing a neighbor

relationship from forming.o The network statement used for EIGRP 55 does not enable EIGRP on interface serial

0/1/0.o The IPv4 address configured on the neighbor that is connected to R1 serial 0/1/0 is

incorrect.o The networks that are configured on serial 0/0/0 and serial 0/1/0 of router R1 are

overlapping.17. Refer to the exhibit. Routers R1 and R2 are directly connected via their

serial interfaces and are both running the EIGRP routing protocol. R1 and R2 can ping the directly connected serial interface of their neighbor, but they cannot form an EIGRP neighbor adjacency.

www.ccna5answers.com www.ccna5blog.com www.ccna-5.com

What action should be taken to solve this problem?

o Enable the serial interfaces of both routers.o Configure EIGRP to send periodic updates.o Configure the same hello interval between the routers.o Configure both routers with the same EIGRP process ID.

18. Refer to the exhibit. Considering that R2, R3, and R4 are correctly configured, why did R1 not establish an adjacency with R2, R3, and R4?

o because the automatic summarization is enabled on R1o because the Fa0/0 interface of R1 is declared as passive for EIGRPo because the IPv4 address on Fa0/0 interface of R1 is incorrecto because there is no network command for the network 192.168.1.0/24 on R1

19. In which scenario will the use of EIGRP automatic summarization cause inconsistent routing in a network?

o when there is no adjacency that is established between neighboring routerso when there is no common subnet that exists between neighboring routerso when the routers in an IPv4 network have mismatching EIGRP AS​ numberso when the routers in an IPv4 network are connected to discontiguous networks with

automatic summarization enabled20. Which command can be issued on a router to verify that automatic

summarization is enabled?o show ip eigrp interfaceso show ip protocolso show ip interface briefo show ip eigrp neighbors

21. Fill in the blank. Do not use abbreviations.What is the command that should be issued on a router to verify that EIGRP adjacencies were formed?​      show ip eigrp neighbors

www.ccna5answers.com www.ccna5blog.com www.ccna-5.com

22. Fill in the blank. Do not use abbreviations.The      passive-interface              command causes an EIGRP router to stop sending hello packets through an interface.

23. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

R1 and R2 could not establish an EIGRP adjacency. What is the problem?​

o EIGRP is down on R1. o EIGRP is down on R2.o R1 Fa0/0 and R2 Fa0/0 are on different networks.o R1 Fa0/0 is not configured to send hello packets.o R1 Fa0/0 link local address is wrong.
