Answers

Suggested answer: A

Explanation:

You can optionally secure the content in your Amazon S3 bucket so users can access it through CloudFront but cannot access it directly by using Amazon S3 URLs. This prevents anyone from bypassing CloudFront and using the Amazon S3 URL to get content that you want to restrict access to. This step isn't required to use signed URLs, but we recommend it To require that users access your content through CloudFront URLs, you perform the following tasks:

Create a special CloudFront user called an origin access identity.

Give the origin access identity permission to read the objects in your bucket.

Remove permission for anyone else to use Amazon S3 URLs to read the objects.

Option B,C and D are all automatically invalid, because the right way is to ensure to create Origin Access Identity (OAI) for CloudFront and grant access accordingly. For more information on serving private content via Cloudfront, please visit the following URL:
