Connecting Networks (Version 6.00) – CN Chapter 6 Exam

QUESTION 1

Which routing protocol is able to scale for large networks and utilizes non-backbone areas for expansion?

EIGRPBGP

OSPF*

RIPv2

QUESTION 2

In the Cisco hierarchical design model, which layer is more likely to have a fixed configuration switch than the other layers?

distributiontransport

internet

access*

core

QUESTION 3

A network engineer is interested in obtaining specific information relevant to the operation of both distribution and access layer Cisco devices. Which command provides common information relevant to both types of devices?
show ip protocolsshow ip interface

show cdp neighbors*

show port-security

show mac-address-table

QUESTION 4

A switched network has converged completely. All switches currently have a VTP revision number of 5. A new switch that has been configured as a VTP server is added to the network. The new switch has a VTP revision number of 4. What will occur within the network?

The network will no longer share VLAN database updates.The newly added switch will automatically switch to VTP client mode.

The VTP databases will remain unchanged in all switches with the exception of the newly added switch.*

All switches in the network will update their VTP database to reflect the VTP database of the new switch.

QUESTION 5

A network administrator is adding a new VLAN for testing. The company uses VTP and the VLAN is not directly attached to either of the switches configured as VTP servers. What is the best method to add this VLAN to the network?

Change the switch that has connected hosts in the new VLAN to be in VTP server mode.Configure a port on the VTP servers for the same VLAN as the new VLAN.

Manually add the VLAN to the VLAN database of the VTP servers.*

Configure interfaces on the switch that has connected hosts in the new VLAN and reboot the switch.

QUESTION 6

Which three pairs of trunking modes will establish a functional trunk link between two Cisco switches? (Choose three.)

dynamic desirable – dynamic desirable*

dynamic auto – dynamic auto

dynamic desirable – dynamic auto*

dynamic desirable – trunk*

access – trunk

access – dynamic auto

QUESTION 7

Refer to the exhibit.The configuration shows the commands entered by a network administrator for inter-VLAN routing. However, host PCA cannot communicate with PCB. Which part of the inter-VLAN configuration causes the problem?

trunking

port mode on the two switch FastEthernet ports

VLAN configuration*

router port configuration

QUESTION 8

Refer to the exhibit.What is the role of the SW3 switch?

designated switch

edge switch

root bridge*

enabled bridge

local bridge

QUESTION 9

Which spanning tree standard was developed by Cisco to provide separate instances of 802.1w per VLAN?

RSTP802.1D

MSTP

Rapid PVST+*

QUESTION 10

Which industry-wide specification was developed to decrease the time that is needed to move to the forwarding state by switch ports that are operating in a redundantly switched topology?VLSMPVST

802.1Q

RSTP*

VTP

QUESTION 11

Refer to the exhibit.A network administrator is verifying the bridge ID and the status of this switch in the STP election. Which statement is correct based on the command output?

The bridge priority of Switch_2 has been lowered to a predefined value to become the root bridge.*

The bridge priority of Switch_2 has been lowered to a predefined value to become the backup root bridge.

The STP instance on Switch_2 is failing due to no ports being blocked and all switches believing they are the root.

The STP instance on Switch_2 is using the default STP priority and the election is based on Switch_2 MAC address.

QUESTION 12

Refer to the exhibit.Which switching technology would allow data to be transmitted over each access layer switch link and prevent the port from being blocked by spanning tree due to the redundant link?

EtherChannel*

HSRP

PortFast

trunking

QUESTION 13

What are two advantages of EtherChannel? (Choose two.)

Configuring the EtherChannel interface provides consistency in the configuration of the physical links.*

Load balancing occurs between links configured as different EtherChannels.

EtherChannel uses upgraded physical links to provide increased bandwidth.

Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection.*

Spanning Tree Protocol ensures redundancy by transitioning failed interfaces in an EtherChannel to a forwarding state.

QUESTION 14

When EtherChannel is implemented, multiple physical interfaces are bundled into which type of logical connection?

interface rangeloopback

VLAN interface

port channel*

QUESTION 15

When a range of ports is being configured for EtherChannel, which mode will configure LACP on a port only if the port receives LACP packets from another device?

activeauto

desirable

passive*
