Answer-first summary for fast verification
Answer: ALB access logs, CloudFront access logs
To investigate HTTP Layer 7 status codes, you need logs that record application-layer traffic. Application Load Balancer (ALB) access logs and Amazon CloudFront access logs both capture detailed information about requests sent to your application, including the HTTP status codes returned to clients. VPC Flow Logs only capture Layer 3/4 network traffic, CloudTrail logs API calls, and RDS logs record database engine activity.
