Q98 — AWS SOA-C02 Ch.1

Question 98 of 100 | ← Chapter 1

A SysOps administrator is maintaining a web application using an Amazon CloudFront web distribution, an Application Load Balancer (ALB), Amazon RDS, and Amazon EC2 in a VPC. All services have logging enabled. The administrator needs to investigate HTTP Layer 7 status codes from the web application. Which log sources contain the status codes? (Choose two.)

• A. VPC Flow Logs
• B. AWS CloudTrail logs
• C. ALB access logs ✓
• D. CloudFront access logs ✓
• E. RDS logs

Correct Answer: C. ALB access logs, D. CloudFront access logs

Explanation

HTTP Layer 7状态码需通过处理应用层请求的服务日志获取。ALB访问日志记录后端服务器响应状态码（如5xx错误），CloudFront访问日志包含客户端请求的HTTP响应码（如403/404）。VPC Flow Logs仅含网络层流量信息，CloudTrail记录API操作审计，RDS日志聚焦数据库事务，均不涉及HTTP状态码。
