What component would you use to manage access rights to shared resources in a network?

The correct choice for managing access rights to shared resources in a network is a Network Access Control List (ACL). An ACL is a set of rules that determines which users or systems have permission to access certain resources, such as files, directories, or network resources. By implementing an ACL, network administrators can specify which users or groups are allowed or denied access to share files or services within a network, effectively helping to maintain security and control over sensitive information.

In a network environment, routers primarily function to direct traffic between different networks and do not inherently manage access rights to resources. Firewalls, while crucial for protecting networks from unauthorized access and controlling the flow of traffic based on security rules, operate at the perimeter of the network rather than managing access rights to specific shared resources directly. Hubs are basic networking devices that merely facilitate data transmission between devices on a network without any ability to filter or restrict access to shared resources. Thus, in the context of managing access rights, a Network Access Control List is the most appropriate and effective solution.
