Selected Answer: C

Elastic Load Balancing (ELB) access logs provide detailed information about the requests made to the ALB, including the originating IP addresses and the EC2 instance that processed each request. These logs are useful for tracking application requests and troubleshooting issues related to load balancing and request processing. When you enable access logs for an Application Load Balancer (ALB), the logs are stored in Amazon S3. The logs contain information such as the timestamp, the client's IP address (originating IP), the request and response details, and the target's IP address (IP address of the EC2 instance that processed the request).
