How should you modify alert definitions so that they fire only when high traffic utilization is sustained for 10 minutes or more?

• A. Configure the alert to trigger only when traffic utilization is sustained for 10 minutes
• B. Lower the threshold to trigger on shorter intervals
• C. Disable the alert during normal hours
• D. Change the evaluation interval to 1 minute

Answer: (A)

The key idea is to require persistence of the condition before firing. You want the alert to go off only after high traffic has lasted for a full 10-minute period, so configure the alert to trigger only if the utilization remains above the threshold for 10 consecutive minutes. This filters out short spikes and keeps alerts meaningful. Lowering the threshold would make alerts happen more often, including brief spikes. Disabling the alert during normal hours would miss important issues, and simply changing the evaluation interval doesn’t by itself guarantee a 10-minute duration unless you also specify a duration requirement.
