CompTIA DataX (CNX-001) — Question 30

After a malicious actor used an open port in a company's lobby, a network architect needs to enhance network security. The solution must enable:

Security posture check -

Auto remediation capabilities -

Network isolation -

Device and user authentication -
Which of the following technologies best meets these requirements?

Answer options

Correct answer: D

Explanation

NAC (Network Access Control) is the most suitable technology as it provides capabilities for security posture assessment, automatic remediation, network segmentation, and ensures that only authenticated devices and users gain access to the network. While 802.1X offers user authentication, it does not inherently include auto remediation or comprehensive network isolation like NAC does. IPS and Microsegmentation serve different purposes and do not fulfill all the listed requirements.
