What set of components do administrators use to regulate network access based on policies?

• A. Network Access Protection
• B. Access Control List
• C. Radius
• D. Virtual Private Network

Answer: (A)

Policy-based network access control hinges on devices proving they meet defined health and security requirements before they can access network resources. Network Access Protection is the framework that brings together the components administrators use to enforce those policies, including health evaluation and remediation mechanisms that work with network access devices to grant or block access based on posture. In contrast, an access control list is a simple filtering rule, RADIUS is a protocol for authenticating and authorizing users, and a VPN is a secure tunnel for remote connectivity; none of these provide the full policy-driven access-control framework that NAP does.
