🛡️ Free practice test question from: Access Control List (Security+)

Access Control Lists (ACLs) are fundamental components in both operating systems and network devices. They specify which users or system processes are granted access to objects (like files, directories, or network resources) and what operations they can perform.

In networking, ACLs are used to control the flow of traffic by permitting or denying packets based on various criteria such as IP addresses, protocols, or ports. This allows for granular control over who can access specific network resources and how data moves through the network.

A) refers to a diagnostic tool, which ACLs are not.

C) describes mechanisms related to packet prioritization and routing, which are typically handled by routing protocols or Quality of Service (QoS) settings, not ACLs.

D) pertains to authentication protocols and credential synchronization, which are outside the scope of ACL functionality.
