Which of the following is a notification that an unusual condition exists and should be investigated?

A.
Alert

B.
Trend

C.
Alarm

D.
Trap

Explanation:
We need to look carefully at the wording of the question to determine the answer. This question is
asking about an “unusual condition” that should be investigated. There are different levels of alerts
from Critical to Warning to Information only.
An Alarm would be triggered by a serious definite problem that needs resolving urgently. An
“unusual condition” probably wouldn’t trigger an alarm; it is more likely to trigger an Alert.
