Which command is used to display access list information?

  1. #show access-lists ACL NUMBER/NAME

  2. #find access-lists

  3. #display access-lists

  4. #list access-lists

The correct answer is: #show access-lists ACL NUMBER/NAME

The command used to display access list information is indeed the one that begins with "show." In Cisco devices, the "show" command is integral for retrieving current operational data from the network device, including configuration settings and statistics. The specific syntax of "show access-lists ACL NUMBER/NAME" allows the user to target a specific access list by its identifier or name, which provides detailed information about the rules and conditions defined within that access list. This information can include permit and deny statements, source and destination addresses, and any associated network services, making it essential for troubleshooting and understanding network behavior. The other commands presented do not correctly reflect the syntax or functionality as per Cisco IOS conventions. The "find," "display," and "list" commands are not standard Cisco commands and would not provide the necessary information regarding access lists. Only the "show" command effectively communicates with the device's operating system to pull information about access lists. This reinforces the importance of recognizing command syntax and understanding how to gather configuration details on Cisco devices during network management and troubleshooting tasks.
