AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineering team must expose a JSON ingestion REST endpoint to several financial partners. Company policy requires each partner to authenticate by presenting an X.509 client certificate issued by the partner's intermediate CA. The endpoint must be reachable only from the company VPC, and the team wants to avoid writing custom certificate-validation logic. Which solution meets these requirements with the least operational overhead?

  • Create a private Amazon API Gateway REST API, enable mutual TLS with a trust store that contains the partners' CA certificates, and access the API through an interface VPC endpoint.

  • Issue an IAM access key and secret key to each partner and require Signature Version 4-signed HTTPS requests to an Internet-facing API Gateway endpoint secured with IAM authorization.

  • Deploy an internal Application Load Balancer with an HTTPS listener configured for mutual TLS verify mode. Create an ELB trust store containing the partners' CA certificates in Amazon S3 and attach it to the listener.

  • Provide partners with presigned Amazon S3 PUT URLs secured with TLS 1.2 so they can upload their data files.
