What Active Scan setting is required for networks using DHCP to track hosts properly?

For networks that utilize DHCP (Dynamic Host Configuration Protocol), the requirement to track hosts properly hinges on the need to maintain accurate records of which devices have been assigned specific IP addresses at any given time. This dynamic nature of IP address allocation means that devices may change IP addresses as they connect and disconnect from the network.

The correct option involves tracking hosts that have been issued IP addresses. This method ensures that the scanning process can accurately identify active devices on the network, even as their IP addresses change over time. By focusing on the issuance of IP addresses, the solution can monitor and manage the security posture of the network effectively, ensuring that any newly assigned device is assessed for compliance and vulnerabilities in real-time.

In contrast, options that do not specifically focus on IP address tracking may not provide the same level of accuracy needed in a dynamic DHCP environment. For example, removing vulnerabilities from inactive hosts or scanning virtual hosts does not directly address the requirement to track changing IP addresses assigned to devices. The rollover option may relate to configuration management but does not enhance the tracking of active devices within a DHCP context.
