What type of information is contained in Amazon CloudFront access logs?

1. Data transfer rates and latencies

2. Every user request that Amazon CloudFront receives

3. Configuration and error details of CloudFront distributions

4. Origin server response times

The correct answer is: Every user request that Amazon CloudFront receives

Amazon CloudFront access logs provide detailed records of every user request that is received by the CloudFront distribution. These logs capture important data such as the time of the request, the requested URL, the originating IP address, the HTTP status codes, and other request-specific information. This enables users to analyze patterns in traffic, understand usage trends, and troubleshoot potential issues related to content delivery. By capturing every user request, these logs are essential for performance monitoring, security auditing, and forensic analysis. They help in understanding how effectively content is being served and can be useful in optimizing caching strategies and improving overall delivery performance. This level of detail is important for developers and network engineers who wish to gain insights into the usage patterns of their applications delivered via CloudFront. In contrast, other options focus on different aspects of CloudFront operations, which are not captured in the access logs. For example, data transfer rates, latencies, configuration details, and origin server response times relate more to the operational performance metrics and settings of CloudFront, rather than being detailed in the user request logs specifically.
