How do you configure a remark for a standard numbered ACL?

To configure a remark for a standard numbered Access Control List (ACL), the correct command syntax is to use "access-list number remark remark". This command allows you to add a descriptive comment to an existing ACL, which can help in documenting the purpose of the rules within the ACL for easier management and understanding.

The "access-list" command is specifically designed to work with numbered ACLs, and the use of "remark" enables you to add clarity to what the ACL is intended to do. This is particularly useful in complex networks where multiple rules can become difficult to interpret without proper documentation.

The other options presented do not correctly match the syntax or functionality required for adding remarks to standard numbered ACLs. Options involving additional permissions or types (deny, permit) or using an "ip access-list" command instead are meant for different types of access lists or actions and do not serve the purpose of remarking a standard numbered ACL.
