1. If a network administrator enters these commands on a
switch, what will be the result?
Switch1(config-line)# line console 0
Switch1(config-line)# password cisco
Switch1(config-line)# login
to configure the privilege exec password that will be used
for remote access
2. Which command line interface (CLI) mode allows users to
configure switch parameters, such as the hostname and password?
global configuration mode
3. What happens when the transport input ssh command is
entered on the switch vty lines?
Communication between the switch and remote users is
encrypted.
4. A network administrator uses the CLI to enter a command
that requires several parameters. The switch responds with "% Incomplete
command". The administrator cannot remember the missing parameters. What
can the administrator do to get the parameter information?
append a space and then ? to the last parameter
5. When a switch receives a frame and the source MAC address
is not found in the switching table, what action will be taken by the switch to
process the incoming frame?
The switch will map the source MAC address to the port on
which it was received.
6.
Refer to the exhibit. The switch and workstation are
administratively configured for full-duplex operation. Which statement
accurately reflects the operation of this link?
No collisions will occur on this link.
7. Refer to the exhibit. The exhibit shows partial output of
the show running-config command. The enable password on this switch is
"cisco." What can be determined from the output shown?
Any configured line mode passwords will be encrypted in this
configuration.
8. Which two statements about Layer 2 Ethernet switches are
true? (Choose two.)
Layer 2 switches have multiple collision domains.
Layer 2 switches can send traffic based on the destination
MAC address.
9. Which statement is true about the command banner login
"Authorized personnel Only" issued on a switch?
The command will cause the message Authorized personnel Only
to display before a user logs in.
10. When a collision occurs in a network using CSMA/CD, how
do hosts with data to transmit respond after the backoff period has expired?
The hosts return to a listen-before-transmit mode.
11. Which two statements are true about EXEC mode passwords?
(Choose two.)
The enable secret password command provides better security
than the enable password.
The enable password and enable secret password protect
access to privileged EXEC mode.
12. Refer to the exhibit. How many collision domains are
depicted in the network?
2
13. Which two statements are true regarding switch port
security? (Choose two.)
Dynamically learned secure MAC addresses are lost when the
switch reboots.
If fewer than the maximum number of MAC addresses for a port
are configured statically, dynamically learned addresses are added to CAM until
the maximum number is reached.
14. What are two ways to make a switch less vulnerable to
attacks like MAC address flooding, CDP attacks, and Telnet attacks? (Choose
two.)
Change passwords regularly.
Turn off unnecessary services.
15. Refer to the exhibit. What action does SW1 take on a
frame sent from PC_A to PC_C if the MAC address table of SW1 is empty?
SW1 floods the frame on all ports on SW1, except port Fa0/1.
16. Refer to the exhibit. The network administrator has
decided to allow only Secure Shell connections to Switch1. After the commands
are applied, the administrator is able to connect to Switch1 using both Secure
Shell and Telnet. What is most likely the problem?
vty lines that are configured to allow only Telnet
17. Where is the startup configuration stored?
NVRAM
18. Refer to the exhibit. The switch and the hub have
default configurations, and the switch has built its CAM table. Which of the
hosts will capture a copy of the frame when workstation A sends a unicast
packet to workstation C?
workstation C
19. Refer to the exhibit. What happens when Host 1 attempts
to send data?
Frames from Host 1 cause the interface to shut down.
20. Refer to the exhibit. Which hosts will receive a
broadcast frame sent from Host A?
hosts B, C, D, and E
