AWS Certified Data Engineer Associate DEA-C01 Practice Question

An e-commerce company ingests about 2,000 JSON events per second (1 KB each) into Amazon Kinesis Data Streams. Two real-time dashboards must receive every record in under 70 ms, while a monthly reporting job replays an entire day of data. Which configuration delivers the requirements at the lowest ongoing cost?

  • Create a provisioned stream with two shards. Attach enhanced fan-out consumers to the two dashboards and have the reporting job poll the stream with GetRecords.

  • Switch the stream to on-demand capacity and give each of the three applications its own enhanced fan-out consumer.

  • Provision four shards and let all three applications retrieve data by polling with the GetRecords API.

  • Send the events to a Kinesis Data Firehose delivery stream that writes to Amazon S3, and have all applications read the objects from S3.
