What is the difference between Network Access Control (NAC) and a Virtual Private Network (VPN)?

The correct answer is C. NAC is used to control network access, while VPN is used to encrypt data. NAC (Network Access Control) enforces policy-based decisions on which devices and users are permitted to connect to a network, often checking compliance (e.g., antivirus status, patch level) before granting access. VPN (Virtual Private Network) creates an encrypted tunnel…

Explanation

NAC (Network Access Control) enforces policy-based decisions on which devices and users are permitted to connect to a network, often checking compliance (e.g., antivirus status, patch level) before granting access. VPN (Virtual Private Network) creates an encrypted tunnel between a client and a network, protecting data in transit from eavesdropping. NAC is about access governance; VPN is about secure, encrypted communication.
