You are building a system to distribute confidential training videos to employees.
Using CloudFront, what method could be used to serve content that is stored in S3, but not publicly accessible from S3 directly?
A . Create an Origin Access Identity (OAI) for CloudFront and grant access to the objects in your S3 bucket to that OAl.
B . Add the CloudFront account security group "amazon-cf/amazon-cf-sg" to the appropriate S3 bucket policy.
C . Create an Identity and Access Management (IAM) User for CloudFront and grant access to the objects in your S3 bucket to that IAM User.
D . Create a S3 bucket policy that lists the CloudFront distribution ID as the Principal and the target bucket as the Amazon Resource Name (ARN).
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.
