Mark works as a Network Administrator for NetTech Inc. He wants users to access only those resources that are required for them. Which of the following access control models will he use?

Discretionary Access Control (DAC) allows resource owners to determine access, which can lead to inconsistent and overly permissive access, not strictly limiting users to only what they require.

Mandatory Access Control (MAC) is based on security labels and strict rules, typically used in highly secure environments, and is less about job function necessity and more about classification levels.

Policy Access Control is a general term and not a distinct access control model like RBAC, DAC, or MAC; policies are used to implement access control, not a model itself.

Role-Based Access Control (RBAC) assigns permissions to roles, and users are assigned to roles, thereby granting them access to only the resources required by their job function or duties.
