M05 Module 18 quiz + notes

What is the difference between the terms keyword and argument in the IOS command structure?

A keyword is a specific parameter. An argument is not a predefined variable. Topic 18.2.0 - Keywords are specific parameters that are defined in IOS. Arguments are not predefined; they are the variables defined by the user when completing a command. Although most keywords appear directly after commands, they can appear in other locations, depending on a command structure. A keyword can be entered in its whole length or in a shortened format.

What function does pressing the Tab key have when an IOS command is entered?

It completes the remainder of a partially typed word in a command Topic 18.2.0 - Pressing the Tab key after a command has been partially typed will cause the IOS to complete the rest of the command.

Which Cisco IOS mode displays a prompt of Router#?

Privileged exec mode Topic 18.1.0 - Cisco IOS uses different command modes for operational needs. The privileged EXEC mode is identified by a prompt that ends with the # symbol after the device name. The user EXEC mode is identified by a prompt that ends with the > symbol after the device name. The global configuration mode is identified by a prompt that ends with (config)# after the device name.

In the show running-config command, which part of the syntax is represented by running-config?

a keyword Topic 18.2.0 - The first part of the syntax, show, is the command, and the second part of the syntax, running-config, is the keyword. The keyword specifies what should be displayed as the output of the show command.

Which command or key combination allows a user to return to the previous level in the command hierarchy?

exit Topic 18.1.0 - End and CTRL-Z return the user to the privileged EXEC mode. Ctrl-C ends a command in process. The exit command returns the user to the previous level.

Immediately after a router completes its boot sequence, the network administrator wants to check the configuration of the router. From privileged EXEC mode, which of the following commands can the administrator use for this purpose? (Choose two.)

show startup-config show running-config Topic 18.3.0 - The show startup-config command can be used to display the Cisco device configuration stored in NVRAM. The show running-config command can be used to display the currently active configuration that is stored in RAM. The show flash command displays the files (not file content) stored in the flash memory.

Refer to the exhibit. An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem?

the administrator must first enter priviledged exec mode before issuing the command Topic 18.1.0 - In order to enter global configuration mode, the command configure terminal, or a shortened version such as config t, must be entered from privileged EXEC mode. In this scenario the administrator is in user EXEC mode, as indicated by the > symbol after the hostname. The administrator would need to use the enable command to move into privileged EXEC mode before entering the configure terminal command.

While troubleshooting a network problem, a network administrator issues the show version command on a router. What information can be found by using this command?

the amount of NVRAM, DRAM, and flash memory installed on the router Topic 18.3.0 - The show version command displays much information about the device, including the amount of memory (flash, NVRAM, and DRAM) that is installed on the device.

Which two statements are true about the user EXEC mode? (Choose two.)

the device prompt for this mode ends with the ">" symbol only some aspects of the router configuration can be viewed Topic 18.1.0 - User EXEC mode limits access to some show and debug commands. It is the first level of user interface encountered when configuring a router and is intended for investigation of certain functions of the device. The User EXEC prompt is identified with the ">" symbol.

An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes?

to interrupt the ping process Topic 18.2.0 - To interrupt an IOS process such as ping or traceroute, a user enters the Ctrl-Shift-6 key combination. Tab completes the remainder of parameters or arguments within a command. To exit from configuration mode to privileged mode use the Ctrl-Z keystroke. CTRL-R will redisplay the line just typed, thus making it easier for the user to press Enter and reissue the ping command.
