Cisco IOS Overview and Command Modes

Which command would you use to save the current configuration to non-volatile RAM?

What is the prompt indicating that the device is in Global Configuration Mode?

Which method should be avoided for remote access due to security concerns?

What command is used to transition from Privileged EXEC Mode to Global Configuration Mode?

Which command will remove the saved configuration from the device?

Cisco IOS provides a graphical user interface for device management.

Telnet is considered a more secure method of remote access compared to SSH.

In Privileged EXEC Mode, the prompt displays as Switch>.

Entering 'end' or pressing Ctrl-Z will bring a user back to User EXEC Mode.

To store the current configuration into NVRAM, the command 'copy startup-config running-config' should be used.

Cisco IOS Overview

Cisco IOS is the operating system for network devices like routers and switches.
It provides a Command-Line Interface (CLI) for managing devices.

Cisco IOS Command Modes

User EXEC Mode: Simple commands, read-only access (prompt: Switch>).
Privileged EXEC Mode: Advanced commands for configuration and management (prompt: Switch#).
Global Configuration Mode: Device-wide settings (prompt: Switch(config)#).
Interface Mode: Configures specific ports (entered from global config mode).
Line Mode: Configures console, Telnet, and SSH access (entered from global config mode).

Important Commands

enable: Enters privileged EXEC mode.
configure terminal: Enters global configuration mode.
exit: Moves to the previous mode.
end or Ctrl-Z: Exits to Privileged EXEC mode.
copy running-config startup-config: Saves current configuration to non-volatile RAM (NVRAM).
erase startup-config: Deletes the saved configuration in NVRAM.

Security Configuration

Passwords: Secure access to privileged EXEC mode using enable secret [password].
Console Access: (Note: Specific commands for securing console access are not listed in the text.)

This quiz covers the basics of Cisco IOS, the operating system used in routers and switches. You'll learn about various command modes such as User EXEC, Privileged EXEC, and Global Configuration, along with important commands.
