Which configurations will support these requirements?
(Choose two.)
Associate an origin access identity with the CloudFront distribution.
Implement a ג€Principalג€: ג€cloudfront.amazonaws.comג€ condition in the S3 bucket policy.
Modify the S3 bucket permissions so that only the origin access identity can access the bucket contents.
Implement security groups so that the S3 bucket can be accessed only by using the intended CloudFront distribution.
Configure the S3 bucket policy so that it is accessible only through VPC endpoints, and place the CloudFront distribution into the specified VPC.
Explanations:
Associating an origin access identity (OAI) with the CloudFront distribution allows CloudFront to access the S3 bucket contents on behalf of users, while preventing direct access via S3 URL.
The conditionPrincipal: cloudfront.amazonaws.comis not valid for restricting S3 access; instead, an OAI should be used in the bucket policy to restrict access to CloudFront.
Modifying the S3 bucket permissions to only allow access from the OAI ensures that only CloudFront can access the bucket contents, fulfilling the requirement of not allowing direct S3 access.
Security groups do not apply to S3 buckets, as they are used for EC2 instances and VPC resources. Access control for S3 is managed via bucket policies and IAM roles, not security groups.
Restricting access via VPC endpoints and placing CloudFront in the same VPC is not necessary or feasible since CloudFront does not require a VPC to interact with S3. An OAI is the correct method for securing access.
Based on what I know, the answer is:
Associate an origin access identity with the CloudFront distribution.
From what I’ve heard, the answer is:
Associate an origin access identity with the CloudFront distribution.
