Which commands can the technician issue at the switch CLI to further troubleshoot the problem? (Choose two.)

Switch# show port security

Switch# show version

Switch# show startup-config

Switch# clear mac-address-table

Switch# reload

Switch# delete flash:vlan.dat

4 Which type of cable is used to connect to the console port on a switch?

a crossover cable

a patch cable

a rollover cable

a straight-thru cable

5 A workstation on a switched Ethernet LAN is to be upgraded with a new Fast Ethernet NIC. What should be done to ensure that the workstation will be able to gain access to the network?

delete the configuration file from the switch and reload IOS

deactivate port security on the port until the new host has connected to the network

remove the host from the the management VLAN until the new MAC address has been learned by the switch

delete the VLAN.dat file from flash and reboot the switch

configure the attached switch port for full-duplex mode

6 What does an amber system LED indicate about a Catalyst switch? (Choose two.)

The switch has power.

The switch has passed POST and is working properly.

The switch has failed POST.

The switch is going through POST.

The switch is in the process of initializing its ports.

7 What must be done in order to initiate the password recovery procedure on a Catalyst 2900 series switch?

Rename the Flash file.

Enter the setup program by deleting the switch configuration file and rebooting the switch.

Hold down the MODE button during switch startup.

Wait for the STAT LED to turn green while holding down the Break key.

Hold down the Ctrl-Break keys during switch startup.

8 From which switch command mode can the configure command be used?


user EXEC

privileged EXEC

command EXEC


9 Which form of switch command-line help displays a list of keywords and arguments that are associated with a command entered at the CLI prompt?

CLI help

keyword help

word help

10 What is the name of the series of tests that execute every time a switch is powered on?



power-on self test

system STAT


11 A new policy for disaster recovery requires copying all critical network configurations and operating systems to a backup server that will be stored offsite. Which command will create a backup of the switch IOS image on the server?

Switch# copy tftp NVRAM

Switch# copy running-config tftp

Switch# copy flash tftp

Switch# copy IOS tftp

Switch# copy tftp flash

Switch# copy NVRAM tftp

12 The network administrator shown in the graphic is connected to Switch3 over Ethernet. The administrator needs to verify configuration settings on the newly installed Switch2. What conditions need to be met in order for the administrator to access Switch2 with a web browser? (Choose three.)


complete IP addressing configured on Switch2

Privileged EXEC mode password configured on Switch2

hostname configured on Switch2

management VLAN password set

HTTP service activated on Switch2

adminstrator host connectivity to the Switch2 management VLAN

13 Which protocol is used to copy a new IOS image to a Catalyst switch during the upgrade procedure?






14 What color is the System LED if the switch fails the POST?






15 Although the backup configuration file on a Catalyst 2950 switch has been erased, it is found that VLANs are still configured in the switch. What must be done to clear the configured VLANs?

The vlan.dat file must be erased and the switch reloaded.

The switch flash memory must be purged and the switch rebooted.

The vlan.cfg file must be renamed and IOS restarted.

Each VLAN needs to be deleted individually and the configuration saved.

The switch needs to be restarted, because the old running configuration is still in memory.
