AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company stores user transactions in an Amazon DynamoDB table. The data engineering team must capture every change and land it in Amazon S3 as compressed Parquet files within 5 minutes so downstream analytics can query the data. The pipeline must be fully serverless, require the least custom code, and automatically evolve the schema when new attributes are added. Which solution meets these requirements?

  • Enable Kinesis Data Streams for the DynamoDB table and configure an Amazon Data Firehose delivery stream with data format conversion to write Parquet files to S3.

  • Trigger an AWS Lambda function from DynamoDB Streams to batch records, convert them to Parquet, and upload the files to S3.

  • Use AWS Database Migration Service (AWS DMS) to replicate the table directly to S3 in Parquet format.

  • Enable DynamoDB on-demand export to S3 and schedule an AWS Glue ETL job to convert the exported JSON files to Parquet.
