Which commands confirm whether port security is configured on a specific switch port?

1. #show port-security status

2. #show running-config and #show security interface INTERFACE

3. #show configuration and #show port interface INTERFACE

4. #show running-config and #show port-security interface INTERFACE

The correct answer is: #show running-config and #show port-security interface INTERFACE

The choice you've identified is indeed correct. To confirm whether port security is configured on a specific switch port, utilizing the commands `show running-config` and `show port-security interface INTERFACE` provides comprehensive information. The `show running-config` command displays the current configuration of the device, allowing you to see the settings for that specific interface, including any port security settings that may have been applied. The `show port-security interface INTERFACE` command is specifically intended to provide details about the port security status and configuration for a particular interface. This includes information such as whether port security is enabled, the maximum number of secure MAC addresses, and the security violation actions configured. Collectively, these commands enable a network administrator to verify whether port security features are enforced and how they are configured on the targeted switch port. This is critical for maintaining network security and integrity.
