CompTIA Network+ Question A-81

The ability to make access decisions based on an examination of Windows registry settings, antivirus software, and AD membership status is an example of which of the following NAC features?

A. Quarantine network
B. Persistent agents
C. Posture assessment
D. Non-persistent agents

Correct Answer: C

Network Admission Control (NAC) can permit or deny access to a network based on characteristics of the device seeking admission, rather than just checking user credentials. For example, a client’s OS, Windows Registry settings, AD membership status, and version of antivirus software could be checked against a set of requirements before allowing the client to access a network.
This process of checking a client’s characteristics is called posture assessment.
