A company stores files and images in S3 across multiple storage classes and has seen a large increase in S3 costs over the past year. A solutions architect must review the past 12 months of data access trends and determine the proper storage class for objects. Which solution provides the required trend analysis?

Amazon S3 Storage Lens provides organization-wide visibility into S3 storage usage and activity, including object access trends over time. By upgrading the default dashboard to include advanced metrics, the solutions architect can analyze access patterns for the past 12 months, identifying infrequently accessed data suitable for cost-effective storage classes. This directly addresses the need for trend analysis to optimize S3 costs. Downloading AWS Cost and Usage Reports (CUR) provides billing details but requires significant manual effort to extract and analyze S3 access trends. S3 Storage Class Analysis focuses on individual buckets and can be complex to aggregate across an organization, and importing into QuickSight adds an unnecessary step when S3 Storage Lens offers built-in dashboards. Access Analyzer for S3 focuses on access permissions, not access patterns or storage class optimization.
