Which features help reduce alert noise in NPM?

• A. Deduplication, reset conditions, and maintenance windows
• B. Increase polling interval
• C. Disable all alerts
• D. Only sending email alerts

Answer: (D)

Reducing alert noise comes from preventing redundant notifications and ensuring only meaningful alerts reach you. Deduplication groups identical alerts that occur within a short time so you don’t get flooded by repeats from the same issue. Reset conditions cause an alert to clear once the monitored metric returns to normal, preventing an alert from staying open or reopening unnecessarily after a transient problem. Maintenance windows suppress alerts during planned downtime, so routine activities don’t trigger noise you already know about. Increasing the polling interval might reduce alert volume by checking less often, but it can delay detection and isn’t aimed at noise control. Disabling all alerts eliminates noise but defeats the purpose of monitoring. Only sending email alerts changes the delivery channel but doesn’t reduce the total number of alerts; it can still overwhelm you if the same issues trigger multiple events across channels.
