global configuration mode

router configuration mode*

interface configuration mode of area 0 interfaces

interface configuration mode of all participating interfaces

R4 is BDR for segment B.

R4 is DR for segment B.

R3 is DR for segment A.*

R2 is DR for segment A.

R3 is BDR for segment B.*

R5 is DR for segment B.*

QUESTION 5

Refer to the exhibit.How did this router learn of the highlighted route in the routing table?

by entering the router configuration mode command default-information originate

by entering the global configuration mode command ip route 0.0.0.0 0.0.0.0 interface-type interface-number

by entering the global configuration mode command ip route 0.0.0.0 0.0.0.0 ip-address

by receiving an update from another OSPF router that is running another routing protocol

by receiving an update from another OSPF router that has the default-information originate command configured*

QUESTION 6

Which command can be used to view OSPF adjacencies with neighboring routers along with the transition state?

show ip protocols

show ip ospf neighbor*

show ip ospf interface

show running-config

QUESTION 7

Match the description to the EIGRP packet type. (Not all options are used.)

QUESTION 8

Match each description to its corresponding LSA type. (Not all options are used.)

QUESTION 9

What is the term that is used for the area of a network that is affected when a device or network service experiences problems?

failure domain*

collision domain

broadcast domain

user domain

QUESTION 10

What term is used to express the thickness or height of a switch?

rack unit*

port density

domain size

QUESTION 11

Which configuration changes will increment the configuration revision number on the VTP server?

configuring trunk links on the VTP serverconfiguring or changing the VTP password

configuring or changing the VTP domain name

configuring or changing the VTP version number

configuring or deleting a VLAN or creating a VLAN name*

QUESTION 12

What are three characteristics of VTP? (Choose three.)

In the default VTP mode, VLANs can be created and modified on a switch.

*Switches in VTP server mode store VLANs in the vlan.dat database.*

VTP-enabled switches exchange three types of advertisements: summary routes, subnet advertisements, and advertisement requests from transparent bridges.

The switch configuration must be saved and the switch reloaded to reset a configuration revision number.

VTP updates are exchanged across trunk links only.*

Switches in different VTP domains can exchange updates if revision numbers are the same.

QUESTION 13

What is the purpose of the vlan.dat file on a switch?

It holds the running configuration.It holds the saved configuration.

It holds the VLAN database.*

It holds the operating system.

QUESTION 14

What eliminates switching loops?

hold-down timerspoison reverse

Spanning Tree Protocol*

Time to Live

VTP

QUESTION 15

A small company network has six interconnected Layer 2 switches. Currently all switches are using the default bridge priority value. Which value can be used to configure the bridge priority of one of the switches to ensure that it becomes the root bridge in this design?
