What command displays general status information of router interfaces?

1. show ip route

2. show ip interface brief

3. debug interface

4. access-list show

The correct answer is: show ip interface brief

The command that displays general status information of router interfaces is indeed the one that provides a concise overview of all interfaces, including their IP addresses, operational status, and other relevant information. When using this command, users can quickly assess whether interfaces are up or down and identify their assigned IP addresses, which is crucial for troubleshooting and monitoring network performance. In contrast, the command that shows the IP routing table is focused on routes rather than interface status. The debug command is used for more detailed output but can overwhelm with excessive information and is typically used for troubleshooting specific issues. Lastly, access-list show commands are dedicated to displaying and managing access control lists, which is not related to the overall status of router interfaces.
