Question

A company with multiple branch locations has an analytics and reporting application. Each branch office pushes a sales report to a shared Amazon S3 bucket at a predefined time each day. The company has developed an AWS Lambda function that analyzes the reports from all branch offices in a single pass. The Lambda function stores the results in a database. The company needs to start the analysis once each day at a specific time. Which solution will meet these requirements MOST cost-effectively?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create an Amazon EventBridge scheduled rule that invokes the Lambda function once each day at the predefined time. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures. This option delivers the requirement at the lowest cost.
