Organizers for a global event will publish daily reports as static HTML pages stored in an Amazon S3 bucket. The pages are expected to generate millions of views worldwide. Which action should a solutions architect take to deliver this content efficiently and effectively?

Using Amazon CloudFront with the S3 bucket as its origin is the most efficient and effective solution. CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide, reducing latency for global users and handling high traffic volumes. This directly addresses the need for millions of views worldwide. Generating presigned URLs is for granting temporary access to private S3 objects, not for public, high-scale content delivery. Cross-Region replication would copy the data but wouldn't provide the low-latency global delivery benefits of a CDN. The geoproximity feature of Amazon Route 53 is for routing traffic to different AWS resources based on user location and resource health, not for caching and delivering static content at the edge.
