network 172.16.23.0 255.255.255.128


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

to accommodate routing of different network layer protocols*

to identify different application layer protocols

to describe different routing processes

to use different transport protocols for different packets


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

EIGRP sends all update packets via unicast.

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

EIGRP uses UDP to send all update packets.

EIGRP sends all update packets via multicast.

bandwidth*

MTU

delay*

load

reliability

Refer to the exhibit. R2 has two possible paths to the 192.168.10.4 network. What would make the alternate route meet the feasibility condition?

a reported distance greater than 41024000

a feasible distance greater than 41024000

an administrative distance less than 170

a reported distance less than 3523840*

10


Refer to the exhibit. Which two networks contain feasible successors? (Choose two.)

192.168.51.0

10.44.101.252

10.44.104.253

10.44.100.252*

192.168.71.0*
11 
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

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?

shutdown
no shutdown

bandwidth 1500

copy running-config startup-config
reload

no bandwidth*

13 
Which EIGRP route would have the preferred administrative distance?

a summary route*

an internal route

an external route that is redistributed from RIP

an external route that is redistributed from OSPF

14 
How do EIGRP routers establish and maintain neighbor relationships?

by comparing known routes to information received in updates

by exchanging routing tables with directly attached routers

by dynamically learning new routes from neighbors

by exchanging hello packets with neighboring routers*

by exchanging neighbor tables with directly attached routers

15 
When an EIGRP-enabled router uses a password to accept routes from other EIGRP-enabled routers, which mechanism is used?

EIGRP authentication*

Diffusing Update Algorithm

Reliable Transport Protocol

bounded updates

partial updates

16 
What is indicated when an EIGRP route is in the passive state?

The route has the highest path cost of all routes to that destination network.

The route is a feasible successor and will be used if the active route fails.

The route is viable and can be used to forward traffic.*

There is no activity on the route to that network.

The route must be confirmed by neighboring routers before it is put in the active state.

17 
Which three metric weights are set to zero by default when costs in EIGRP are being calculated? (Choose three.)

k6

k3

k5*

k4*

k2*

k1

18 
Why would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?

to send a manual summarization

to exclude some interfaces from the EIGRP process*

to subnet at the time of the configuration

to lower the router overhead

19 
Which table is used by EIGRP to store all routes that are learned from EIGRP neighbors?

the adjacency table

the routing table

the topology table*

the neighbor table

20 
Where are EIGRP successor routes stored?

only in the routing table

in the routing table and the topology table*

only in the neighbor table

in the routing table and the neighbor table

21

Launch PT – Hide and Save PT
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

Which code is displayed on the web server?

Done

Complete*

EIGRP

IPv6EIGRP

22 
Which command is used to display the bandwidth of an interface on an EIGRP-enabled router?

show ip protocols

show interfaces*

show ip interface brief

show ip route

23 
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.
