SCS-C02 Amazon GuardDuty Practice Question
Which TWO AWS services can be used to detect anomalous API activity in an AWS account? (Choose two.)
⚠ Common exam trap
The trap is that candidates may select VPC Flow Logs or AWS Config because they are associated with security monitoring, but they do not directly detect anomalous API activity. Additionally, some candidates might think only GuardDuty is a threat detection service and overlook that CloudTrail Insights also provides anomaly detection.

Correct answer & explanation
✓
Amazon GuardDuty
Amazon GuardDuty is a threat detection service that uses machine learning and anomaly detection to identify suspicious API activity. AWS CloudTrail, with the CloudTrail Insights feature, provides continuous monitoring and detection of anomalous API activity by analyzing management events and generating insights. Additionally, CloudTrail logs can be used with Amazon CloudWatch to set up metric filters and alarms for detecting unusual patterns. Therefore, both GuardDuty and CloudTrail are valid services for detecting anomalous API activity.
