CCNA3 v6.0 Chapter 6 Exam Answers

1. When an EIGRP-enabled router uses a password to accept routes from other EIGRP-enabled routers, which mechanism is used?

bounded updates

partial updates

EIGRP authentication*

Diffusing Update Algorithm

Reliable Transport Protocol

2. What is the purpose of using protocol-dependent modules in EIGRP?

to describe different routing processes

to identify different application layer protocols

to use different transport protocols for different packets

to accommodate routing of different network layer protocols*

3. If all router Ethernet interfaces in an EIGRP network are configured with the default EIGRP timers, how long will a router wait by default to receive an EIGRP packet from its neighbor before declaring the neighbor unreachable?

10 seconds

15 seconds*

20 seconds

30 seconds

4. Which statement describes a characteristic of the delivery of EIGRP update packets?

EIGRP uses UDP to send all update packets.

EIGRP sends all update packets via unicast.

EIGRP sends all update packets via multicast.

EIGRP uses a reliable delivery protocol to send all update packets.*

5. Which two EIGRP packet types are sent with unreliable delivery? (Choose two.)






6. Which destination MAC address is used when a multicast EIGRP packet is encapsulated into an Ethernet frame?





7. What is identified within the opcode of an EIGRP packet header?

the EIGRP message type that is being sent or received from a neighbor*

the EIGRP autonomous system metrics

the EIGRP hold timer agreed upon with a neighbor

the EIGRP sum of delays from source to destination

8. An administrator issues the router eigrp 100 command on a router. What is the number 100 used for?

as the autonomous system number*

as the number of neighbors supported by this router

as the length of time this router will wait to hear hello packets from a neighbor

as the maximum bandwidth of the fastest interface on the router

9. Why would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?

to lower the router overhead

to send a manual summarization

to exclude some interfaces from the EIGRP process*

to subnet at the time of the configuration

10. What information does EIGRP maintain within the routing table?

both successors and feasible successors

only feasible successors

adjacent neighbors

all routes known to the router

only successors*

11. Which table is used by EIGRP to store all routes that are learned from EIGRP neighbors?

the routing table

the neighbor table

the topology table*

the adjacency table

12. Which command or commands must be entered on a serial interface of a Cisco router to restore the bandwidth to the default value of that specific router interface?

bandwidth 1500

no shutdown

copy running-config startup-config

no bandwidth*

13. Which three metric weights are set to zero by default when costs in EIGRP are being calculated? (Choose three.)







14. A new network administrator has been asked to verify the metrics that are used by EIGRP on a Cisco device. Which two EIGRP metrics are measured by using static values on a Cisco device? (Choose two.)






15. Refer to the exhibit.

Which two networks contain feasible successors? (Choose two.)**

16. A network administrator wants to verify the default delay values for the interfaces on an EIGRP-enabled router. Which command will display these values?

show ip protocols

show running-config

show interfaces*

show ip route

17. Refer to the exhibit.

R3 has two possible paths to the network. What is the reported distance of the feasible successor route?





18. Refer to the exhibit.

R2 has two possible paths to the network. What would make the alternate route meet the feasibility condition?

a reported distance less than 3523840*

a reported distance greater than 41024000

a feasible distance greater than 41024000

an administrative distance less than 170

19. Which two factors does an EIGRP router use to determine that a route to a remote network meets the feasible condition and is therefore loop-free? (Choose two.)

the successor route on a neighbor router

the feasible successor route on the remote router

the reported distance on a neighbor router*

the administrative distance on the remote router

the feasible distance on the local router*

20. Which configuration is necessary to ensure successful operation of EIGRP for IPv6?

The eigrp router-id command requires an IPv6 address within the router configuration mode.​

The network command is required within the router configuration mode.​

The no shutdown command is required within the router configuration mode.​*

The router eigrp autonomous-system command is required within the router configuration mode.

21. Fill in the Blank. Use the abbreviation.

EIGRP uses the protocol “RTP” to deliver EIGRP packets to neighbors.​

22. Fill in the blank.

In an EIGRP topology table, a route that is in a/an “active” state will cause the Diffusing Update Algorithm to send EIGRP queries that ask other routers for a path to this network.

23. Order the precedence in which an EIGRP router would choose the router ID. (Not all options are used.)

eigrp router-id command = first

highest IPv4 address on active physical interfaces = third

highest IPv4 address on loopback interfaces = second

24. Match the correct version of EIGRP with the EIGRP features. (Not all options are used.)

source address for EIGRP messages is a routable address = EIGRP for IPv4 only

uses a 32-bit router ID = both EIGRP for IPv4 and EIGRP for IPv6

source address for EIGRP messages is a link-local address = EIGRP for IPv6 only

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

Which code is displayed on the web server?
