    Which of the following is a difference between Telnet and SSH as supported by a Cisco switch?

    • SSH encrypts the passwords used at login, but not other traffic; Telnet encrypts nothing.

    • SSH encrypts all data exchange, including login passwords; Telnet encrypts nothing.

    • Telnet is used from Microsoft operating systems, and SSH is used from UNIX and Linux operating systems.

    • Telnet encrypts only password exchanges; SSH encrypts all data exchanges.

    Correct Answer
    A. SSH encrypts all data exchange, including login passwords; Telnet encrypts nothing.
    Explanation
    SSH encrypts all data exchange, including login passwords, while Telnet does not encrypt any data. This means that when using SSH, all communication between the client and the server, including the login credentials, is encrypted, providing a secure connection. On the other hand, Telnet does not provide any encryption, making it vulnerable to eavesdropping and unauthorized access.

    Imagine that you have configured the enable secret command, followed by the enable password command, from the console. You log out of the switch and log back in at the console. Which command defines the password that you had to enter to access privileged mode?

    • Enable password

    • Enable secret

    • Neither

    • The password command, if it’s configured

    Correct Answer
    A. Enable secret
    Explanation
    The enable secret command is used to set a password for accessing privileged mode. When logging back in at the console, the password that needs to be entered to access privileged mode is the one set by the enable secret command.

    What type of switch memory is used to store the configuration used by the switch when it is up and working?

    • RAM

    • ROM

    • Flash

    • NVRAM

    • Bubble

    Correct Answer
    A. RAM
    Explanation
    RAM, or Random Access Memory, is the type of switch memory used to store the configuration used by the switch when it is up and working. RAM is a volatile memory, meaning that its contents are lost when power is turned off or interrupted. However, it provides fast read and write access, making it ideal for storing temporary data such as the switch configuration.

    Which of the following describes a way to disable IEEE standard autonegotiation on a 10/100 port on a Cisco switch?

    • Configure the negotiate disable interface subcommand

    • Configure the speed 100 and duplex full interface subcommands

    • Configure the speed 100 interface subcommand

    • Configure the duplex half interface subcommand

    • Configure the duplex full interface subcommand

    Correct Answer
    A. Configure the speed 100 and duplex full interface subcommands
    Explanation
    The correct answer is to configure the speed 100 and duplex full interface subcommands. This is because setting the speed to 100 and duplex to full manually disables the autonegotiation feature of the IEEE standard on a 10/100 port on a Cisco switch. Autonegotiation allows devices to automatically negotiate and select the best speed and duplex settings for communication. By manually configuring the speed and duplex, the switch will not negotiate with the connected device and will operate at the specified settings.

    • No banner text is displayed.

    • The banner text “his is” is displayed.

    • The banner text “this is the login banner” is displayed.

    • The banner text “Login banner configured, no text defined” is displayed.

    Correct Answer
    A. The banner text “his is” is displayed.
    Explanation
    When a user logs in from the console after the given command is executed, the banner text "his is" will be displayed.

    Rate this question:

  • 9. 

    A switch user is currently in console line configuration mode. Which of the following would place the user in enable mode?

    • Using the exit command once

    • Using the exit command twice in a row

    • Pressing the Ctrl-z key sequence

    • Using the quit command

    Correct Answer(s)
    A. Using the exit command twice in a row
    A. Pressing the Ctrl-z key sequence
    Explanation
    Using the exit command twice in a row or pressing the Ctrl-z key sequence would both place the user in enable mode. The exit command is used to exit the current mode and return to the previous mode. By using it twice in a row, the user would exit console line configuration mode and return to the user EXEC mode, and then exit the user EXEC mode and enter enable mode. Pressing the Ctrl-z key sequence is another way to exit console line configuration mode and enter enable mode.

    Correct Answer(s)
    A. User mode
    A. Enable mode
    Explanation
    The command "show mac-address-table" can be executed in both User mode and Enable mode. In User mode, the command provides a read-only view of the MAC address table. In Enable mode, the command provides a more detailed view of the MAC address table, including additional information such as VLAN assignments. It cannot be executed in Global configuration mode, Setup mode, or Interface configuration mode.

    The show vlan brief command lists the following output:2    my-vlan                       active    Fa0/13, Fa0/15Which of the following commands could have been used as part of the configuration for this switch?

    • The vlan 2 global configuration command

    • The name MY-VLAN vlan subcommand

    • The interface range Fa0/13 - 15 global configuration command

    • The switchport vlan 2 interface subcommand

    Correct Answer
    A. The vlan 2 global configuration command
    Explanation
    The correct answer is the vlan 2 global configuration command. This command is used to create a VLAN with the VLAN ID of 2 in the global configuration mode. The output of the show vlan brief command indicates that a VLAN with ID 2, named "my-vlan", is active and is associated with the FastEthernet interfaces Fa0/13 and Fa0/15. Therefore, it can be inferred that the vlan 2 global configuration command was used to create and activate this VLAN.

    An engineer’s desktop PC connects to a switch at the main site. A router at the main site connects to each branch office via a serial link, with one small router and switch at each branch. Which of the following commands must be configured, in the listed configuration mode, to allow the engineer to telnet to the branch office switches?

    • The ip address command in VLAN 1 configuration mode

    • The ip address command in global configuration mode

    • The ip default-gateway command in global configuration mode

    • The password command in console line configuration mode

    • The password command in vty line configuration mode

    Correct Answer(s)
    A. The ip address command in VLAN 1 configuration mode
    A. The ip default-gateway command in global configuration mode
    A. The password command in vty line configuration mode
    Explanation
    To allow the engineer to telnet to the branch office switches, the following commands must be configured:

    1. The ip address command in VLAN 1 configuration mode: This command is necessary to assign an IP address to the VLAN 1 interface on the branch office switches, allowing them to communicate with other devices on the network.

    2. The ip default-gateway command in global configuration mode: This command is required to set the default gateway address on the branch office switches, enabling them to send traffic to devices outside their local network.

    3. The password command in vty line configuration mode: This command is used to set a password for remote access to the branch office switches via Telnet. It ensures that only authorized users can access the switches remotely.

    An engineer had formerly configured a Cisco 2960 switch to allow Telnet access so that the switch expected a password of mypassword from the Telnet user. The engineer then changed the configuration to support Secure Shell. Which of the following commands could have been part of the new configuration?

    • A username name password password command in vty config mode

    • A username name password password global configuration command

    • A transport input ssh command in vty config mode

    • A transport input ssh global configuration command

    Correct Answer(s)
    A. A username name password password global configuration command
    A. A transport input ssh command in vty config mode
    Explanation
    The engineer changed the configuration to support Secure Shell, which means that Telnet access is no longer allowed and SSH access is enabled instead. To configure SSH access, the engineer would have used the "A transport input ssh command in vty config mode" to specify that only SSH connections are allowed on the virtual terminal lines. Additionally, the engineer would have used the "A username name password password global configuration command" to create a username and password for authentication when accessing the switch via SSH.
