What is the primary purpose of implementing Network Admission Control?

1. To monitor network traffic

2. To enforce network security policy for devices that join the network

3. To manage user credentials

4. To provide internet access to employees

The correct answer is: To enforce network security policy for devices that join the network

The primary purpose of implementing Network Admission Control (NAC) is to enforce network security policy for devices that join the network. NAC is designed to ensure that only compliant devices are allowed access to the network based on predetermined security policies. By evaluating the security posture of devices before granting them access, NAC helps prevent unauthorized access and protects the network from potential threats, such as malware or unpatched vulnerabilities. This mechanism ensures that devices meet specific security requirements, such as having up-to-date antivirus software, operating systems, and security patches. By controlling which devices can connect to the network, NAC enhances the overall security and integrity of network resources, as it ensures that only trusted and securely configured devices can communicate on the network. The other options—monitoring network traffic, managing user credentials, and providing internet access—are related to broader network management and security practices, but they do not specifically represent the core function of Network Admission Control.
