Which action should the solutions architect take to accomplish this?
Generate presigned URLs for the files.
Use cross-Region replication to all Regions.
Use the geoproximity feature of Amazon Route 53.
Use Amazon CloudFront with the S3 bucket as its origin.
Explanations:
Generating presigned URLs allows temporary access to S3 files but does not efficiently handle millions of views globally.
Cross-Region replication helps in data redundancy but does not optimize for content delivery or high traffic access.
The geoproximity feature of Route 53 is used for routing based on user location, but it does not cache or efficiently serve static content.
Using Amazon CloudFront with the S3 bucket as its origin provides a Content Delivery Network (CDN) that efficiently delivers static content globally, reducing latency and
I have a feeling that the answer is:
Use Amazon CloudFront with the S3 bucket as its origin.
