Which solution will meet these requirements?
Deploy the updated version of the website to another S3 bucket. Update the origin for CloudFront.
Delete the marketing content in the existing S3 bucket. Invalidate the file path in CloudFront.
Create a new CloudFront cache policy with a low TTL. Associate the new policy with the existing CloudFront distribution.
Delete the marketing content in the existing S3 bucket. Update the S3 bucket policy to block requests to the file path.
Explanations:
Deploying to another S3 bucket and updating the origin for CloudFront would take additional time and complexity. This approach does not provide a quick removal of the marketing content already cached by CloudFront.
Deleting the marketing content from the existing S3 bucket and invalidating the file path in CloudFront ensures that the outdated content is removed quickly from the cache, allowing the new, updated content to be served immediately.
Creating a new CloudFront cache policy with a low TTL does not remove the marketing content from the cache immediately. The old content would still be served until the TTL expires, which does not meet the requirement for immediate removal.
Deleting the marketing content is a good step, but merely updating the S3 bucket policy to block requests to the file path would not remove the cached content from CloudFront. Users could still receive the old cached version until it expires.
