Which action is most appropriate to prevent future discoveries of the same devices (for example, five Windows 10 workstations) from appearing in discovery results?

• A. Add to Ignore List
• B. Change SNMP community string
• C. Disable the NPM service
• D. Reinstall NPM

Answer: (A)

The main idea here is to tell the discovery process to skip those devices in future scans. Adding the Windows 10 workstations to the Ignore List does exactly that: any hosts on the ignore list are excluded from subsequent discovery runs, so they won’t reappear in discovery results while their existing monitoring continues. Changing the SNMP community string would affect how those devices respond to SNMP, but it doesn’t prevent discovery from finding them again, and it could disrupt monitoring. Disabling the NPM service would stop all monitoring, not just discovery, and reinstalling NPM isn’t targeted to stop re-discovery of specific devices.
