AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineering team must trigger an AWS Glue crawler as soon as new JSON files are written to the s3://company-data/raw/iot/ prefix by an IoT application. The solution should require no custom code or servers to manage while ensuring that only those objects start the crawler. Which approach meets these requirements in the most operationally efficient way?

  • Configure an AWS Lambda function that is invoked by S3 object-created notifications and calls the Glue StartCrawler API in its code.

  • Create a Kinesis Data Firehose delivery stream for the bucket and use its data transformation trigger to launch the Glue crawler.

  • Create an EventBridge rule that filters for ObjectCreated events from the bucket with prefix raw/iot/ and suffix .json, and set the rule's target to the Glue StartCrawler API.

  • Set up an AWS Glue workflow schedule that periodically scans the raw/iot/ prefix and starts the crawler when new files are found.
