AWS Certified Data Engineer Associate DEA-C01 Practice Question

Every night at 02:00 UTC a third-party exposes a new daily_sales.csv file through its REST API. You need a serverless ingestion pipeline that automatically downloads the file to Amazon S3 at that time with minimal ongoing administration. Which solution satisfies these requirements?

  • Deploy Amazon MWAA and schedule an hourly DAG that checks the vendor endpoint, downloads the file when available, and stores it in S3.

  • Configure an Amazon S3 event notification that triggers a Lambda function to fetch the file from the vendor API when a new object appears in the destination bucket.

  • Launch an Amazon EC2 instance and configure a Linux cron job at 02:00 UTC to download the file to S3 using the AWS CLI.

  • Create an Amazon EventBridge rule with a 02:00 UTC cron expression that invokes an AWS Lambda function to call the vendor API and write the file to Amazon S3.
