Free Cisco ENCOR Lan Switches Question and Answers

Question 1

Change the status of the DUPLX (duplex) LED. Choose the appropriate response(s) for the matching hue and description.

Accepted Answer

LED is green means full duplex

Answer

On Cisco switches, the DUPLX LED indicates the duplex status of an interface. A green LED signifies that the interface is operating in full-duplex mode, meaning it can send and receive data simultaneously. If the LED is off, it indicates that the interface is not operating in any duplex mode, often implying no link or a problem with the connection.

Question 2

This places the cursor on the command's first character in the presently visible command string.

Accepted Answer

Ctrl-A

Answer

In Cisco IOS CLI, the `Ctrl-A` key combination is a common shortcut used to move the cursor to the beginning of the current command line. This allows users to quickly edit or review the start of a command without having to repeatedly press the left arrow key. It's a fundamental text editing shortcut also found in many other command-line interfaces and text editors.

Question 3

On a switch, debugging is enabled. For instance, I wish to debug the IP ICMP packet switch. Debugging would end if I would

Accepted Answer

All of the above

Answer

All the listed methods can effectively stop debugging on a Cisco switch. Typing `no debug IP ICMP` specifically disables the debug for IP ICMP. `undebug all` or `no debug all` globally disables all active debugging sessions, and reloading the switch also clears all runtime configurations, including debugging, as debug commands are not persistent across reloads by default.

Question 4

This advances the cursor in the command that is currently removing characters.

Accepted Answer

Backspace

Answer

The Backspace key is used to move the cursor backward one character at a time while simultaneously deleting the character at the cursor's previous position. This allows for immediate correction of typing errors by removing characters as the cursor retreats. It's a standard text editing function across most computing environments, including the Cisco IOS CLI.

Question 5

Switch(config)#? The command above will

Accepted Answer

List only available commands in the CONFIGURATION mode

Answer

In Cisco IOS, typing a question mark (`?`) after a command or at a prompt provides context-sensitive help. When entered at the `Switch(config)#` prompt, it will display a list of all commands that are available specifically within the global configuration mode. This helps users discover valid commands and their syntax for the current operational context.
