Question

A company runs a single CloudFront distribution for its website. Static assets (images, CSS, JS) are served from an Amazon S3 bucket, while dynamic API requests under the path '/api/*' must be forwarded to an Application Load Balancer. Currently all requests, including '/api/*', are being routed to the S3 origin, causing API calls to fail. Which configuration change correctly routes traffic to the appropriate origins?

Accepted Answer

Add the ALB as a second origin and create a cache behavior with path pattern '/api/*' that points to the ALB origin, keeping the default (*) behavior pointed at S3.

Answer

Create a second CloudFront distribution for the ALB and use Route 53 weighted routing to split traffic between the two distributions.

Answer

Enable origin failover with an origin group so that requests failing at S3 automatically fall back to the ALB origin.

Answer

Modify the S3 bucket policy to redirect '/api/*' requests to the ALB endpoint using an S3 website redirection rule.
