Operating Cisco IOS Software Flashcards
Which three of the following options are network features and functions provided by Cisco IOS Software? (Choose three.)
A. Cisco IOS Software provides access control features.
B. Cisco IOS Software supports network protocols that perform routing functions.
C. Cisco IOS Software supports network scalability.
D. Cisco IOS Software accepts user input and outputs responses only for the CLI and not for the GUI session.
E. Cisco IOS Software enables you to view configuration videos during console sessions.
A. Cisco IOS Software provides access control features.
B. Cisco IOS Software supports network protocols that perform routing functions.
C. Cisco IOS Software supports network scalability.
Which two statements about the Cisco IOS Software CLI are true? (Choose two.)
A. You can always enter any command, regardless of the mode you are in.
B. You can easily tell which command mode you are in because each mode has a distinctive prompt.
C. When you finish typing in a command, you have to press Enter to execute it.
D. By default, every prompt begins with the name of the mode.
E. If you do not have authorization to access the Privileged EXEC Mode, the CLI will allow you to view the Privileged EXEC Mode commands, but not to execute them.
B. You can easily tell which command mode you are in because each mode has a distinctive prompt.
C. When you finish typing in a command, you have to press Enter to execute it.
Which statement about the CLI operation modes is correct?
A. To change from the Privileged EXEC Mode to the Interface Configuration Mode, you have to type the configure terminal command first and then type the interface command.
B. To change from the User EXEC Mode to the Interface Configuration Mode, you have to type interface command.
C. By typing the exit command, you leave the Interface Configuration Mode and go to the Privileged EXEC Mode.
D. By typing the end command, you leave the Interface Configuration Mode and go to the User EXEC Mode.
A. To change from the Privileged EXEC Mode to the Interface Configuration Mode, you have to type the configure terminal command first and then type the interface command.
The correct answer is “To change from the Privileged EXEC Mode to the Interface Configuration Mode, you have to type the configure command.” If you are in the Privileged EXEC Mode, to get to the Interface Configuration Mode, you have to enter the Global Configuration Mode first, which you can do by typing in the configure command. You cannot enter the Interface Configuration Mode directly from the User EXEC Mode. With the exit command you move from the lower to the next higher operation mode, therefore, the exit command typed in the Interface Configuration Mode changes to Global Configuration Mode. The end command makes you leave the current mode and lend always in the Privileged EXEC Mode.
Which command merges the configuration that is saved in NVRAM into the running configuration?
A. copy startup-config running-config
B. copy run start
C. copy NVRAM running-config
D. copy running-config NVRAM
A. copy startup-config running-config
Which parameter is used with the show command output to display all output lines starting with the line that matches the filtering expression?
A. begin
B. exclude
C. include
D. section
A. begin
The correct answer is “begin.” When the begin parameter is used with the show output, the system displays all output lines, starting with the line that matches the filtering expression.
Which Cisco IOS command do you use to change from User EXEC Mode into Privileged EXEC Mode?
A. enable
B. disable
C. admin
D. configure
E. configure terminal
A. enable
What is the expected result of the show running-config | exclude ! command executed on the Cisco IOS device?
A. CLI will display the negated versions of the commands in the running configuration file.
B. CLI will display the running configuration file but without any lines containing “!” in them
C. CLI will display only the lines copied from the external source.
D. CLI will display only the lines different to the lines in the startup-config file.
B. CLI will display the running configuration file but without any lines containing “!” in them
In Cisco IOS Software, what are the two EXEC access levels? (Choose two.)
A. admin EXEC
B. user EXEC
C. privileged EXEC
D. basic EXEC
E. advanced EXEC
B. user EXEC
C. privileged EXEC
While configuring a router, the network engineer typed the following sequence:
R1#show ip access-list R1#show ip interface brief R1#configure terminal R1(config)#interface GigabitEthernet 0/2 R1(config-if)#description Protected Access R1(config-if)#end R1#
The engineer is using the terminal history help feature to recall previously used commands. The engineer used the Up Arrow key twice. Which command from the sequence did the engineer recall?
A. show ip access-list
B. description Protected Access
C. interface GigabitEthernet 0/2
D. configure terminal
E. show ip interface brief
E. show ip interface brief
Which option is available to a network engineer to interact with a network device?
A. A network engineer communicates directly with the device operating system using machine programming languages.
B. A shell program exposes operating system services and can be accessed via CLI or GUI.
C. A hardware input device, such as mouse, can be used to directly interact with the device.
D. The operating system can only communicate with the user through light indicators present on the outside of the hardware.
B. A shell program exposes operating system services and can be accessed via CLI or GUI.
How does the Privileged EXEC Mode restrict the access to the configuration CLI commands?
A. The Privileged EXEC Mode provides access security by adding an additional password when trying to reach the configuration modes.
B. By default, the Privileged EXEC Mode asks users to enter passwords for entering the Global Configuration Mode.
C. Access to the Privileged EXEC Mode can be password-protected to allow only authorized users to execute the privileged set of commands
D. Commands entered in the Privileged EXEC Mode intentionally show false device information for unauthorized users.
C. Access to the Privileged EXEC Mode can be password-protected to allow only authorized users to execute the privileged set of commands
