AWS Certified Developer Associate DVA-C02 Practice Question

A developer is building an application that allows users to upload images for processing. The processing can take several minutes, and traffic is unpredictable. The application must remain responsive, allowing users to submit images without waiting for the processing to complete. Which approach BEST meets these requirements?

  • Decouple the submission process from the image processing by using an Amazon SQS queue. The application can add messages to the queue and respond to the user immediately.

  • Use a synchronous API Gateway integration with an AWS Lambda function to process the image immediately upon upload.

  • Store the uploaded images in an Amazon S3 bucket and have the user's browser poll an API endpoint until the processing is finished.

  • Deploy the image processing logic on an Amazon EC2 instance and have the web server make a direct, blocking call to the processing service.
