If you want an alert to send an email on initial occurrence, which trigger condition best accomplishes this?

• A. Volume Space Used is greater than 90%
• B. Volume Space Used is less than 60%
• C. Volume Space Used equals 100%
• D. Volume Space Used is between 70% and 80%

Answer: (A)

This tests how alerts trigger on the first crossing of a threshold. You want to email when usage first becomes problematic, so the trigger should fire as soon as the metric exceeds a defined high level. Setting Volume Space Used to be greater than 90% does exactly that: the alert fires the moment storage usage goes above 90%, sending the email on the initial occurrence. The other options don’t fit the goal: less than 60% would alert on unusually low usage, not the high-usage event you want; equals 100% would only fire if usage is exactly full—an unlikely, narrow condition that misses the initial crossing; and between 70% and 80% would be true for a range of usage and could cause chatter or miss the initial crossing to high usage.
