Final answer:
Implementing VLANs (Virtual Local Area Networks) is an effective way to segregate the remediation network for non-compliant clients from the main secure network within a NAP infrastructure.
Step-by-step explanation:
You are in the process of configuring a remediation network for non-compliant clients as part of a Network Access Protection (NAP) infrastructure to improve your network's security. The remediation network is intended to help non-compliant systems update their settings to meet the network compliance standards while being isolated from the secure network. To accomplish this task, the best technology to implement would be VLANs (Virtual Local Area Networks). VLANs can effectively segregate the non-compliant devices within the remediation network while maintaining a barrier from the secure network. This ensures that the two networks do not interact, keeping your main network secure from possible threats posed by non-compliant systems.
