- A
AWS CloudTrail
Why wrong: CloudTrail logs the activity but does not generate alerts natively; it needs to be paired with CloudWatch.
- B
AWS Config
Why wrong: Config evaluates resource configurations, not user activity.
- C
AWS Security Hub
Why wrong: Security Hub aggregates findings but does not detect root usage itself.
- D
Amazon GuardDuty
GuardDuty has a finding for 'RootCredentialUsage' and can generate alerts.

CCSP Cloud Security Operations Practice Question
This CCSP practice question tests your understanding of cloud security operations. 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 when the root user account is used in AWS. Which service can generate an alert for this activity?
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
✓
Amazon GuardDuty
Amazon GuardDuty is a threat detection service that continuously monitors for malicious or unauthorized behavior, including the use of the root user account. It uses machine learning and integrated threat intelligence to generate findings for such activities, which can then trigger alerts via Amazon CloudWatch Events or AWS Lambda. This makes it the correct choice for detecting root user usage.
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 AWS CloudTrail's logging capability with alerting, assuming it can directly generate alerts, when in fact it only records events and requires integration with other services for notification.
Detailed technical explanation
How to think about this question
GuardDuty analyzes CloudTrail management event logs, VPC Flow Logs, and DNS logs to detect anomalies. For root user detection, it specifically monitors for the 'RootCredentialUsage' finding type, which triggers when the root user's credentials are used for API calls. This is a subtle behavior because root user activity is often legitimate for initial setup, but GuardDuty can be configured to alert on any such usage, helping to enforce the principle of least privilege.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
