A company hosts a static website on Amazon S3 fronted by CloudFront. They want to ensure the website remains available even if the primary S3 bucket is accidentally deleted or becomes unavailable. What is the MOST cost-effective solution?

Answer options:

Use Route 53 failover routing between two CloudFront distributions.

Create a secondary S3 bucket in another region. Configure CloudFront Origin Groups with failover routing.

Enable S3 Cross-Region Replication and use an Application Load Balancer to route traffic.

Deploy the website on EC2 instances in multiple regions.

How to approach this question

Identify the native CloudFront feature for high availability.

Full Answer

B.Create a secondary S3 bucket in another region. Configure CloudFront Origin Groups with failover routing.✓ Correct

CloudFront Origin Groups allow you to specify a primary and secondary origin. If the primary returns an error (like 404 or 500), CloudFront automatically routes the request to the secondary origin.

Common mistakes

Using Route 53 for failover when CloudFront can handle it natively at the edge.
