How should the developer resolve this issue?
Configure S3 Object Lock to update to the latest version of the files every time an S3 object is updated.
Configure the S3 bucket to clear all old objects from the bucket before new artifacts are uploaded.
Set CloudFront to invalidate the cache after the artifacts have been deployed to Amazon S3.
Set CloudFront to modify the distribution origin after the artifacts have been deployed to Amazon S3.
Explanations:
S3 Object Lock is used to prevent objects from being deleted or overwritten for a specific retention period. It does not affect the visibility of updated files on CloudFront or the caching behavior.
Clearing old objects from the S3 bucket is unnecessary and does not resolve caching issues with CloudFront. CloudFront can still cache content even if old objects are removed from S3.
Invalidating the CloudFront cache will ensure that CloudFront fetches the latest versions of the artifacts from the S3 bucket. This is the standard approach to update cached content delivered by CloudFront.
Modifying the distribution origin is not relevant to updating cached content. The origin change would not automatically invalidate the cache or ensure that new artifacts are served.
I systematize that the answer is:
Set CloudFront to invalidate the cache after the artifacts have been deployed to Amazon S3.
