This SCS-C02 practice question tests your understanding of threat detection and incident response. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO AWS services can be used to detect anomalous behavior in an AWS environment?
AWS Config
Why wrong: Config is for resource configuration compliance, not anomaly detection.
Amazon GuardDuty
GuardDuty detects anomalies using ML and threat intelligence.
AWS CloudTrail
Why wrong: CloudTrail logs API calls but does not detect anomalies.
Amazon Inspector
Why wrong: Inspector assesses vulnerabilities, not anomalies.
AWS Security Hub
Security Hub provides a unified view of security alerts and can detect anomalies.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon GuardDuty
Amazon GuardDuty and AWS Security Hub both provide anomaly detection. GuardDuty uses machine learning to detect threats. Security Hub aggregates findings and can detect anomalies through integrated services. AWS Config is for compliance. AWS CloudTrail is logging. Amazon Inspector is for vulnerabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Config
Why it's wrong here
Config is for resource configuration compliance, not anomaly detection.
Amazon GuardDuty
Why this is correct
GuardDuty detects anomalies using ML and threat intelligence.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
