AWS Certified Developer Associate DVA-C02 Practice Question

A developer is tasked with setting up a serverless architecture for processing incoming data requests from web clients. The system should respond with a client error status code and a structured message when a submission does not conform to the expected input format. Which serverless components should the developer configure to ensure these requirements are met?

  • Utilize a dedicated AWS Lambda function to perform input validation and shape the error return upon detecting non-conforming data.

  • Configure Amazon CloudFront custom error responses to intercept and reshape the return provided by the backend services.

  • Implement AWS Step Functions to orchestrate input validation and construct an error document to be issued when an invalid request is detected.

  • Leverage Amazon API Gateway's request validation feature and tailor the integration response to deliver a structured message upon failure.
