Which of the following is a cause of this?
The S3 bucket must be configured with Amazon CloudFront first
The Route 53 record set must have an IAM role that allows access to the S3 bucket
The Route 53 record set must be in the same region as the S3 bucket
The S3 bucket name must match the record set name in Route 53
Explanations:
The S3 bucket does not require CloudFront to serve static content. The S3 bucket can be directly configured to serve static website content without CloudFront.
IAM roles are not required for Route 53 to route traffic to an S3 bucket. The issue is more likely related to the configuration of the bucket or record set.
Route 53 records can be created in any region. The region of the Route 53 record set does not need to match the region of the S3 bucket.
The S3 bucket name must exactly match the domain name (e.g.,www.anycompany.com) for Route 53 to route traffic correctly. This is a common requirement for S3 static website hosting.
I classify that the answer is:
The S3 bucket name must match the record set name in Route 53
