What is the name of the list attached to a file or object that specifies who can access it and with what permissions?

• A. Authentication
• B. Access Control List
• C. Authorization
• D. Accessibility

Answer: (B)

This question tests how access to a file or object is controlled and described. An Access Control List is a list attached to a resource that specifies which users or groups can access it and what actions they are allowed to perform. It lays out the exact permissions for each principal, such as read, write, or execute, making it clear who can do what with the item.

Authentication is about proving who you are, not about listing permissions. Authorization is the process of determining whether a given identity has permission to perform an action, but the actual token of permissions for each user or group is implemented via the Access Control List. Accessibility isn’t a standard term used to describe per-resource permissions in this context.
