SCS-C02 Threat Detection and Incident Response Practice Question
A company uses AWS Organizations with multiple accounts. The security team wants to centrally collect and analyze CloudTrail logs from all accounts in a single S3 bucket. What is the most efficient way to achieve this?
⚠ Common exam trap
Many exam-takers assume each account must have its own trail (Option A) or that a streaming solution like CloudWatch Logs (Option B) is required, overlooking the native organization-level trail feature that simplifies centralization.
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
✓
Create a single organization trail in the management account that logs all accounts.
AWS Organizations supports creating a single organization trail in the management account that automatically logs CloudTrail events for all accounts in the organization. This centralizes log collection into one S3 bucket without needing to configure trails per account, making it the most efficient and scalable approach for multi-account environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a CloudTrail trail in each account and configure the same S3 bucket as the destination.
Why it's wrong here
This would require manual setup per account and may cause permission issues.
- ✗
Use CloudWatch Logs subscription filter to send logs from each account to a central account.
Why it's wrong here
This would require additional setup and resources; not the most efficient.
- ✓
Create a single organization trail in the management account that logs all accounts.
Why this is correct
Organization trails automatically apply to all accounts in the organization.
- ✗
Use S3 cross-region replication to copy logs from each account's bucket to a central bucket.
Why it's wrong here
Cross-region replication is not designed for this purpose and adds latency.
