AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company stores build artifacts in an S3 bucket. The CloudOps team must run a Lambda function only when an object of at least 500 MB is uploaded to the bucket's incoming/ prefix. The function must not be invoked for any other uploads, and the solution should require the least custom code and incur minimal cost. Which configuration meets these requirements?

  • Create an AWS Step Functions state machine that runs every five minutes, lists objects in the bucket, and invokes the Lambda function for any object larger than 500 MB in the incoming/ prefix.

  • Create an Amazon EventBridge rule that filters PutObject events where detail.object.key starts with "incoming/" and detail.object.size is greater than or equal to 524 288 000 bytes; set the Lambda function as the rule's target.

  • Configure an S3 event notification on the bucket with a prefix filter of "incoming/" and set the Lambda function as the destination.

  • Enable CloudTrail data events on the bucket, deliver logs to a separate S3 bucket, and configure that bucket to trigger the Lambda function on new log file creation.
