Which command can be issued on a router to verify that automatic summarization is enabled?

2
Which address best summarizes the IPv6 addresses 2001:DB8:ACAD::/48, 2001:DB8:9001::/48, and 2001:DB8:8752::/49?

3

Refer to the exhibit. Router R3 is receiving multiple routes through the EIGRP routing protocol. Which statement is true about the implementation of summarization in this network?

4

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?

5
In which IOS CLI mode must a network administrator issue the maximum-paths command to configure load balancing in EIGRP?​

6
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?​

7

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 problem?

8
In which scenario will the use of EIGRP automatic summarization cause inconsistent routing in a network?

9

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.

10

Refer to the exhibit. Which statement accurately reflects the configuration of routing on the HQ router?

11

Refer to the exhibit. Which statement is supported by the output?

12

Refer to the exhibit. Which two routes will be advertised to the router ISP if autosummarization is disabled? (Choose two.)

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. What is a possible cause for this failure?

14
Two routers, R1 and R2, share a 64 kb/s link. An administrator wants to limit the bandwidth used by EIGRP between these two routers to 48 kb/s. Which command is used on both routers to configure the new bandwidth setting?

15
Which three statements are advantages of using automatic summarization? (Choose three.)

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 most likely cause of this problem?

17
What is a characteristic of manual route summarization?

18
Fill in the blank. Do not use abbreviations.

19

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

20
Fill in the blank. Do not use abbreviations.

21

Launch PT   Hide and Save PT
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?​

22

Refer to the exhibit. A network administrator has attempted to implement a default route from R1 to the ISP and propagate the default route to EIGRP neighbors. Remote connectivity from the EIGRP neighbor routers to the ISP connected to R1 is failing. Based on the output from the exhibit, what is the most likely cause of the problem?

23

Refer to the exhibit. All networks are active in the same EIGRP routing domain. When the auto-summary command is issued on R3, which two summary networks will be advertised to the neighbors? (Choose two.)

24. By default, how many equal-cost routes to the same destination network will EIGRP install in the routing table?

25. Which administrative distance is used to advertise routes learned from other protocols that are redistributed into EIGRP?

26. What is the purpose of a Null0 route in the routing table?

27. Refer to the exhibit.

Router CiscoVille has been partially configured for EIGRP authentication. What is missing that would allow successful authentication between EIGRP neighbors?

28. Refer to the exhibit.

Which two conclusions can be drawn from the exhibited configuration? (Choose two.)

29. Which EIGRP parameter must match between all routers forming an EIGRP adjacency?

30. What two statements are correct regarding EIGRP authentication? (Choose two.)

31. Which command would limit the amount of bandwidth that is used by EIGRP for protocol control traffic to approximately 128 Kb/s on a 1.544 Mb/s link?

32. Refer to the exhibit.

All networks are active in the same EIGRP routing domain. When the auto-summary command is issued on R3, which two summary networks will be calculated on R3? (Choose two.)
