SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A company uses AWS Organizations with multiple accounts. They want to centralize VPC flow logs for all VPCs across accounts. The logs should be stored in a central S3 bucket in the management account. What is the MOST efficient way to achieve this?
⚠ Common exam trap
Many candidates assume VPC Flow Logs must be delivered via CloudWatch Logs first, or that CloudTrail can manage flow logs, when in fact S3 bucket policies with organization-level conditions provide a direct and scalable solution.
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
✓
Use a bucket policy on the central S3 bucket to allow cross-account delivery from all accounts.
A bucket policy on the central S3 bucket can grant the necessary permissions for VPC Flow Logs from any account in the organization to be delivered directly to that bucket. This approach avoids the overhead of managing individual delivery configurations and leverages AWS Organizations to simplify cross-account permissions, making it the most efficient centralized solution.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use a bucket policy on the central S3 bucket to allow cross-account delivery from all accounts.
Why this is correct
Bucket policy allows any account to deliver logs to that bucket.
- ✗
Enable VPC flow logs at the organization level using CloudTrail.
Why it's wrong here
CloudTrail does not enable VPC flow logs.
- ✗
Create a flow log in each account and configure it to deliver to a central S3 bucket.
Why it's wrong here
Requires manual configuration per account.
- ✗
Use CloudWatch Logs in each account and stream to a central log group.
Why it's wrong here
Not centralized in S3 as required.
