AWS Certified Data Engineer Associate DEA-C01 Practice Question

A gaming company captures real-time session events from Amazon Kinesis Data Streams. The backend must persist each player's most recent 24-hour session data, handle unpredictable spikes to millions of writes per second, and return player records in single-digit milliseconds by primary key. Operations wants a fully managed, auto-scaling or serverless solution with built-in TTL so stale data is deleted automatically. Which AWS data store best meets these requirements?

  • Amazon S3 bucket storing JSON objects queried through Amazon Athena and S3 Lifecycle rules

  • Amazon Redshift streaming ingestion into an RA3 cluster with automatic table sort keys

  • Amazon Aurora MySQL Serverless v2 cluster with auto-scaling read/write endpoints

  • Amazon DynamoDB table with on-demand capacity and TTL enabled
