SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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.
A security team wants to detect and alert on potential security threats such as compromised instances or malicious activity within their AWS environment. Which TWO AWS services should be used together to provide comprehensive threat detection?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Security Hub
Amazon GuardDuty (Option E) is a threat detection service that continuously monitors for malicious activity and unauthorized behavior using machine learning, anomaly detection, and integrated threat intelligence feeds. AWS Security Hub (Option A) aggregates findings from GuardDuty and other services, applies automated compliance checks, and enables centralized alerting and response. Together, they provide comprehensive threat detection by combining GuardDuty's raw threat detection with Security Hub's aggregation and orchestration capabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse logging services (CloudTrail, Config) or vulnerability scanners (Inspector) with active threat detection, but GuardDuty and Security Hub are the only pair that provide continuous, intelligent threat monitoring and centralized alerting.
Detailed technical explanation
How to think about this question
GuardDuty uses integrated threat intelligence from AWS Security Hub, CrowdStrike, and Proofpoint, and analyzes VPC Flow Logs, DNS logs, and CloudTrail management events to detect threats like cryptocurrency mining, port scanning, and unusual API calls. Security Hub consumes GuardDuty findings via the AWS Security Finding Format (ASFF) and can trigger automated remediation through AWS Lambda and EventBridge. In a real-world scenario, if an EC2 instance is compromised and starts outbound traffic to a known malicious IP, GuardDuty generates a finding, which Security Hub then centralizes and can route to a SIEM or incident response workflow.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
