Which of the following allows for the creation of policies to evaluate connected devices and determine access to a network?

The choice that correctly describes the system allowing for the creation of policies to evaluate connected devices and determine their access to a network is Network Access Control (NAC).

NAC solutions play a critical role in security by enforcing policies for endpoint devices that try to connect to a network. These policies can involve checking the compliance of devices against security standards, ensuring that they have up-to-date antivirus software, proper configurations, and any necessary patches applied. If a device does not meet these specified criteria, NAC can restrict its access or even block it from the network entirely until compliance is achieved.

This proactive approach helps organizations manage potential risk by ensuring that only secure and compliant devices can access sensitive network resources. In contrast to other options, NAC focuses specifically on assessing devices before granting them access, making it integral to maintaining a secure network environment.
