AWS Certified Developer - Associate DVA-C02 — Topic 1 Question 3

Question

An application is using Amazon Cognito user pools and identity pools for secure access. A developer wants to integrate the user-specific file upload and download features in the application with Amazon S3. The developer must ensure that the files are saved and retrieved in a secure manner and that users can access only their own files. The file sizes range from 3 KB to 300 MB. Which option will meet these requirements with the HIGHEST level of security?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Use an IAM policy within the Amazon Cognito identity prefix to restrict users to use their own folders in Amazon S3. Amazon S3 provides durable, scalable object storage that is fully managed. AWS IAM controls authenticated and authorized access to AWS resources with fine-grained policies. Amazon Cognito manages user sign-up, sign-in and federated identity for applications.
