Identify the command required to verify a switch's IP address.

1. #show ip interface status

2. #show ip interface brief

3. #ip config

4. #display ip address

The correct answer is: #show ip interface brief

The command to verify a switch's IP address is indeed the one that shows the status of all interfaces along with their assigned IP addresses in a concise form. It provides a brief overview that includes the interface status, protocol status, IP addresses, and other useful information. This makes it particularly suited for quickly checking the IP address configuration on a switch. The simplicity of this command allows network administrators to quickly confirm that the desired IP address is configured correctly and to see at a glance whether any interfaces are administratively down or experiencing issues. This command streamlines the process of monitoring interface configurations and their statuses. Other commands, while relevant in their own contexts, do not provide the same comprehensive overview or focus explicitly on the IP addressing of the interfaces. Some options might not even be recognized in the context of Cisco IOS commands. Thus, choosing the command that succinctly delivers the necessary information on IP configuration is the most effective way to achieve the goal of verifying a switch's IP address.
