Explanation

Role-Based Access Control (RBAC) is the correct choice because it is specifically designed to tie permissions and network function access to user roles - meaning what a user can do on the network is determined by the role assigned to them (e.g., admin, guest, read-only). When setting up user roles, RBAC is the mechanism that enforces which network functions each role may access or modify.

• A. VLAN Policies - VLANs segment traffic at the network layer but don't govern what individual users or roles are permitted to do; they separate broadcast domains, not user permissions.
• C. Network Segmentation - This is a broader architectural concept (dividing a network into zones) and doesn't directly map user roles to specific access rights or function restrictions.
• D. QoS Settings - Quality of Service prioritizes traffic types for performance; it has nothing to do with restricting user access to network functions.

Memory tip: Think of RBAC as a "badge system" - your badge (role) determines which doors (network functions) you can open. Any time a question mentions user roles + restricting access, the answer is RBAC.
