  Which AWS service should the company use to meet this requirement?

  A. AWS Managed Services (AMS)
  B. AWS CodeStar
  C. Amazon EventBridge
  D. AWS Step Functions
  C. Amazon EventBridge

  ---

  Explanation/Reference:

  C. Amazon EventBridge

  Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, SaaS applications, and AWS services. It allows you to create rules that automatically trigger an AWS Lambda function in response to specific events from supported sources, such as an S3 bucket.

  In this case, the company could use EventBridge to create a rule that triggers the Lambda function processing data in the S3 bucket once a day at a specific time. The rule could be set to match the S3 bucket's "Put" or "Update" events, and include a schedule expression that defines the specific time of day when the function should be invoked. This would allow the company to easily set up a scheduled daily processing of data in the S3 bucket without having to run or manage any additional infrastructure.
