Question #891
A company needs to monitor access patterns and object size distribution across Amazon S3 buckets in two AWS Regions to optimize storage costs. The company requires a centralized dashboard to visualize these metrics for the finance team. Which solution will meet these requirements with the LEAST operational overhead?
Deploy AWS Lambda functions in each Region to collect object size and access data. Store the data in Amazon DynamoDB and use Amazon QuickSight to build a custom dashboard with aggregated metrics for the finance team.
Create an Amazon EventBridge rule to capture S3 API events via AWS CloudTrail. Use a Lambda function to process the events and log metrics in Amazon CloudWatch. Build a CloudWatch dashboard to display the aggregated data.
Use the S3 Storage Lens default dashboard to track object size distribution and access patterns. Grant the finance team access to the dashboard directly in the S3 console.
Configure AWS Config rules in each Region to monitor S3 object sizes and access activity. Export the data to Amazon S3 and use Athena queries to generate reports for a custom QuickSight dashboard.
Explanation
Answer C is correct because Amazon S3 Storage Lens is a native tool designed to monitor S3 storage usage and activity across buckets and regions. It offers a centralized default dashboard with pre-configured metrics, including object size distribution and access patterns, eliminating the need for custom code, Lambda functions, or additional services. Options A, B, and D involve significant operational overhead due to manual data collection, processing, and dashboard creation. S3 Storage Lens simplifies the process by providing a ready-to-use solution, making it the most efficient choice.
Key Points:
- S3 Storage Lens is purpose-built for S3 storage analytics.
- Default dashboard requires no coding or infrastructure setup.
- Aggregates data across regions automatically.
- Minimizes operational effort compared to custom Lambda/QuickSight/CloudWatch workflows.
Answer
The correct answer is: C
