Cisco Switch Privileged Exec Mode Prompt

A

The correct answer is A. switch#.

In Cisco networking devices, there are different modes of operation that provide different levels of access to the device's configuration and commands. These modes are:

1. User EXEC mode: This is the default mode when you connect to a Cisco device. In this mode, you have limited access to the device's commands and can only execute a subset of commands that are not very sensitive or critical.

2. Privileged EXEC mode: Also known as enable mode, this mode provides full access to the device's configuration and commands. To enter this mode, you need to enter the command "enable" and provide the enable password if configured.

3. Global configuration mode: This mode is used to configure the device's settings globally, such as hostname, IP address, routing protocols, and more. To enter this mode, you need to enter the command "configure terminal" or "conf t" in privileged EXEC mode.

4. Interface configuration mode: This mode is used to configure settings for a specific interface, such as its IP address, subnet mask, speed, duplex, and more. To enter this mode, you need to enter the command "interface <interface>" in global configuration mode.

So, when a Cisco switch is running in privileged EXEC mode, it displays the prompt "switch#" to indicate that you have full access to the device's configuration and commands. The other prompts mentioned in the question are used for different modes:

• "switch(config)#" is used for global configuration mode.
• "switch(config-if)#" is used for interface configuration mode.
• "switch>" is used for user EXEC mode.
