What Active Scan setting must be enabled for networks using DHCP to track endpoints properly?

• A. Remove vulnerabilities from scanned hosts that have been inactive for (X days)
• B. Track hosts which have been issued new IP addresses
• C. Scanning virtual hosts
• D. Rollover Option

Answer: (B)

The correct answer, which emphasizes tracking hosts that have been issued new IP addresses, is crucial for networks utilizing DHCP (Dynamic Host Configuration Protocol). DHCP dynamically assigns IP addresses to devices on the network, meaning that as devices connect and disconnect, their IP addresses can change frequently. Enabling settings that allow tracking of hosts with new IP addresses ensures that the ACAS can maintain an accurate and up-to-date inventory of all devices on the network. This is particularly important for vulnerability management and compliance assessments, as it ensures that all endpoints are monitored properly for security issues, regardless of any changes in their IP configuration. Other options do not directly address the need for tracking changing IP addresses in DHCP-managed environments. For instance, removing vulnerabilities from inactive hosts does not assist with the dynamic nature of DHCP, while scanning virtual hosts and the rollover option do not specifically pertain to the necessity of monitoring IP changes. This highlights why the tracking of hosts issued new IP addresses is essential for effective network security management in environments using DHCP.
