A systems administrator wants to use a technical solution to explicitly define file permissions for the entire team. Which of the following should the administrator implement?
Correct Answer: A
An Access Control List (ACL) is a technical mechanism used to explicitly define permissions for files, folders, or other resources. ACLs specify which users or system processes are granted access to objects and what operations are allowed on given objects. This allows the administrator to centrally and granularly manage file permissions for a group or team.
