How would you use Zenmap to compare two scans and identify differences in hosts or services?

• A. Use Zenmap’s Compare feature to overlay two scan results; highlights added/removed hosts, ports, services, and versions.
• B. Export two scans as CSV and compare them in a spreadsheet.
• C. Zenmap automatically merges results from two scans into a single file.
• D. Zenmap cannot compare scans.

Answer: (A)

When you want to see how a network has changed over time, use Zenmap’s Compare feature. It lets you load two saved scan results and overlay them so you can spot differences at a glance. The comparison highlights what’s new or gone between the scans—hosts that appear or disappear, ports that have opened or closed, services that have changed, and even version updates for identified services. This makes it easy to track changes in your environment without manually tallying each item. To do it, save both scans in Zenmap, open one, then open the other, and choose the Compare Results option to select the two scans. The resulting view shows color-coded diffs that clearly indicate added, removed, or changed elements, helping you quickly identify what changed between the two scans. Exporting to CSV isn’t the built-in method for comparing within Zenmap and doesn’t provide the integrated diff visualization; Zenmap also doesn’t automatically merge two scans into a single file. The Compare feature is the intended way to identify differences.
