Ccna3 Chapter 8

Front 1

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.)

Back 1

* 192.168.10.0/24
* 172.16.0.0/16

Front 2

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?

Back 2

* Automatic summarization is disabled on R3.

Front 3

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

Back 3

* A default route is being learned through an external process.

Front 4

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

Back 4

* It reduces the frequency of routing updates.
* It ensures that traffic for multiple subnets uses one path through the internetwork.
* It decreases the number of entries in the routing table.

Front 5

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

Back 5

* 10.1.2.0/24
* 10.1.4.0/30

Front 6

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

Back 6

* 2001:DB8:8000::/34

Front 7

What is a characteristic of manual route summarization?

Back 7

* reduces total number of routes in routing tables

Front 8

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

Back 8

* A static default route was configured on this router.

Front 9

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?

Back 9

* The command redistribute static has not been issued on R1.

Front 10

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

Back 10

* router configuration mode

Front 11

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?

Back 11

* ip bandwidth-percent eigrp 100 75

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

Back 12

* serial 0/1/0 of R2
* serial 0/0/1 of R3

Front 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?

Back 13

* The same autonomous system numbers must be used in the interface configurations of each router.

Front 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?

Back 14

* an access list that is blocking advertisements from other networks

Front 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 problem?

Back 15

* The GigabitEthernet 0/1 interface is not participating in the EIGRP process.

Front 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?

Back 16

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

Front 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.What action should be taken to solve this problem?

Back 17

* Configure both routers with the same EIGRP process ID.

Front 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?

Back 18

* because the Fa0/0 interface of R1 is declared as passive for EIGRP

Front 19

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

Back 19

* when the routers in an IPv4 network are connected to discontiguous networks with automatic summarization enabled

Front 20

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

Back 20

* show ip protocols

Front 21

What is the command that should be issued on a router to verify that EIGRP adjacencies were formed?

Back 21

show ip eigrp neighbors

Front 22

The __________ command causes an EIGRP router to stop sending hello packets through an interface.

Back 22

passive-interface

Front 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?

Back 23

* EIGRP is down on R1.
