AWS Certified Data Engineer Associate DEA-C01 Practice Question

An e-commerce company loads 3 TB of new transactional data into its data warehouse on Amazon S3 every day. A 4-node Amazon Redshift RA3 cluster currently satisfies most analytic queries, but at month-end up to 400 concurrent connections cause queueing and long runtimes. The company wants to maintain current cost for daily operations and pay only for the occasional spikes. Which solution meets these requirements with minimal administration?

  • Enable Concurrency Scaling on the existing Amazon Redshift RA3 cluster to add transient compute during high-concurrency periods.

  • Resize the cluster to 16 RA3 nodes so it can handle the month-end workload without queueing.

  • Migrate the workload to Amazon Redshift Serverless and set the base capacity to support 400 concurrent queries.

  • Move the data warehouse to Amazon RDS for PostgreSQL and configure Auto Scaling read replicas for additional capacity.
