Which CloudWatch feature uses ML to learn the normal range of a metric and fires alarms when values deviate from that learned baseline?
AStatic threshold alarms only
BCloudWatch anomaly detection alarms
CAmazon RDS
DAWS Snowball
Answer & Solution
Correct answer: B. CloudWatch anomaly detection alarms
Anomaly detection alarms learn baselines (per DOP-C02 §4.2). Static alarms can't adapt; RDS/Snowball are unrelated.
