CHAPTER 2 QUES. & ANSWERS

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 secure the console port with the password "cisco"
to deny access to the console port by specifying 0 lines are available to gain access to line configuration mode by supplying the required password 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? user EXEC mode

privileged EXEC mode
global configuration mode
interface configuration mode
3. What happens when the transport input ssh command is entered on the switch vty lines? The SSH client on the switch is enabled.
Communication between the switch and remote users is encrypted. A username/password combination is no longer needed to establish a secure remote connection to the switch. The switch requires remote connections via proprietary client software. 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 ? to the last parameter

append a space and then ? to the last parameter
use Ctrl-P to show a parameter list
use the Tab key to show which options are available
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 request that the sending node resend the frame. The switch will issue an ARP request to confirm that the source exists. The switch will map the source MAC address to the port on which it was received. The switch ends an acknowledgement frame to the source MAC of this incoming frame. 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.

Only one of the devices can transmit at a time.
The switch will have priority for transmitting data.
The devices will default back to half duplex if excessive collisions occur. 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? The enable password is encrypted by default.

An MD5 hashing algorithm was used on all encrypted passwords. Any configured line mode passwords will be encrypted in this configuration. This line represents most secure privileged EXEC mode password possible. 8. Which two statements about Layer 2 Ethernet switches are true? (Choose two.) Layer 2 switches prevent broadcasts.

Layer 2 switches have multiple collision domains.
Layer 2 switches route traffic between different networks.
Layer 2 switches decrease the number of broadcast 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 is entered in privileged EXEC mode.

The command will cause the message Authorized personnel Only to display before a user logs in. The command will generate the error message % Ambiguous command: "banner motd" ” to be displayed. The command will cause the message End with the character “%” to be displayed after the command is entered into the switch. 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.

The hosts creating the collision have priority to send data. The hosts creating the collision retransmit the last 16 frames. The...
