AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineer loads transformed sales totals into Amazon Redshift Serverless each night. An external partner needs to query the current day's total over the internet through a low-latency HTTPS endpoint. The partner cannot obtain AWS credentials but can pass an API key for authentication. The solution must remain fully serverless and require the least operational overhead. Which approach satisfies these requirements?

  • Create a REST API in Amazon API Gateway that requires an API key and invokes an AWS Lambda function, which queries Amazon Redshift through the Redshift Data API and returns JSON.

  • Expose the Amazon Redshift Data API endpoint to the partner and store database credentials in AWS Secrets Manager.

  • Deploy a microservice on Amazon ECS Fargate behind an Application Load Balancer that connects to Amazon Redshift with JDBC and returns results.

  • Write the daily total to a JSON file in an Amazon S3 bucket and share a presigned URL with the partner.
