AWS Certified Data Engineer Associate DEA-C01 Practice Question

A startup collects point-of-sale transactions from several third-party systems. Records are streamed to Amazon S3 with Amazon Kinesis Data Firehose and must be immediately accessible to partners that use many different analytics tools, some of which run outside AWS. The company wants a storage format that keeps ingestion latency and transformation effort as low as possible while remaining human-readable and easy to exchange. Which file format should the data engineer choose?

  • Convert the data to Apache Parquet before writing to Amazon S3.

  • Deliver the data in Apache ORC format to Amazon S3.

  • Store the records in CSV files on Amazon S3.

  • Serialize the records as Apache Avro files on Amazon S3.
