What is the primary purpose of Network Access Control (NAC)? To increase the speed of network connections To authenticate endpoints before they fully connect to the network To manage network traffic To monitor network performance

The answer is To authenticate endpoints before they fully connect to the network

Network Access Control (NAC) is primarily used to authenticate and authorize devices before they are allowed to fully connect to a network. This ensures that only compliant and secure devices gain access, enhancing network security. So Option 2 is correct.

Here are further explanations:

• Option 1: To increase the speed of network connections

NAC does not directly increase network speed.

• Option 3: To manage network traffic

While NAC can influence traffic based on access policies, its primary goal isn't traffic management.

• Option 4: To monitor network performance

NAC focuses on access control rather than continuous network performance monitoring.
