- ✗
The VPC Flow Logs are not enabled for the correct VPC
Why it's wrong here
The administrator enabled them, so they are enabled.
- ✓
The IAM role for Flow Logs does not have permissions to write to S3
Why this is correct

- ✗
The RDS instance is in a private subnet

The S3 bucket is in a different region
Why it's wrong here
S3 is global; cross-region delivery is allowed.
