3.1 CCNA 3 - Module 6

1

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

2
Which commands can be used to change from Global
Configuration mode to Privileged EXEC mode? (Choose three.)
Ctrl+z
disable
end
exit
logout

3
An administrator is using the switch help facility to find the
command elements available to the configure command.
What would the user type at the command prompt to display
the next set of arguments available in the syntax for this command?
Switch# c?
Switch# c ?
Switch# configure?
Switch# configure ?

4
Which switch command mode should always be password protected?
User Command
User Config
User EXEC
User Privileged
Privileged EXEC

5
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.

6
Which protocol is used to copy a new IOS image to a Catalyst
switch during the upgrade procedure?
HTTP
Telnet
TFTP
TTY
IOS

7
A group of hosts has been connected to a new Fast Ethernet switch.
Which of the following statements describe this newly created LAN,
if the new switch has not yet been configured? (Choose three.)
The hosts will negotiate 10 Mbps or 100 Mbps bandwidth with
the switch, as required by their NICs.
The hosts will be in separate broadcast domains.
All of the hosts will be in the same VLAN.
Hosts with 10 Mbps NICs will be unable to communicate with
the network.
All of the hosts should be able to send and receive ARP messages
from each other.
All of the hosts connected by Ethernet can manage the switch
over Telnet or HTTP.

8
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

9
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.

10
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

11
From which switch command mode can the configure command
be used?
config
user EXEC
privileged EXEC
command EXEC
flash

12
An old workstation has been replaced with a new one.
The workgroup switch, a Catalyst 2950, is not learning the
MAC address of the new workstation. A network technician
has verified that a static MAC address is not configured on the
attached switch port. Which two 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 dynamic
Switch# reload
Switch# delete flash:vlan.dat

13
Which methods can be used to perform the initial configuration
of a new switch? (Choose two.)
copy a configuration from a FTP server
type commands manually after entering the Privileged
EXEC mode
enter the System Configuration dialog
Telnet to a local server to copy a configuration file
connect to the switch using a web browser

14
How long will a host MAC address remain in the address table
of a switch after the host has been turned off or moved to
another device?
30 seconds
180 seconds
300 seconds
30 minutes

15
What is the name of the series of tests that execute every
time a switch is powered on?
RPS
bootstrap
power-on self test
system STAT
pre-boot

16
After powering up a switch, the network technician notices
that the system LED is amber. What can the technician assume?
(Choose two.)
The switch is negotiating full or half-duplex mode.
The switch has completed negotiating 10 or 100 Mbps speed.
The POST has failed.
The boot sequence is in process.
A fatal error has occurred.
The switch is operating properly and is ready for service.

17
When the copy tftp flash command is used to upgrade the IOS
on a switch, which symbol indicates that the image was copied
successfully?
e
*
!
s
#

18
What color is the System LED if the switch fails the POST?
amber
green
red
white
off

19
How can a switch be configured to prevent unauthorized hosts
from access to a network? (Choose three.)
Host MAC addresses can be statically assigned to each
switch port.
Layer 2 access control lists can be used to prevent
unauthorized network access.
Unused ports can be shutdown.
Passwords and usernames can be set for each Ethernet
switch port.
Unused switch ports can be assigned to the management
VLAN.
Port security can be activated to allow only the host with
the first MAC address learned on a port to access the network.

20
Which files must be deleted in order to completely remove
an existing configuration from a Cisco 2950 switch? (Choose two.)
flash:c2950-c3h2s-mz.120-5-3.WC.1.bin
running-config
VLAN.bin
startup-config
c2950-c3h2s-mz.120-5-3.WC.1.dat
VLAN.dat
