Selected Answer: AE
A: Enable CloudFront Origin Shield for the required AWS Regions. Provides: better cache hit ratio, reduced origin load, and better network performance. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/origin-shield.html E: Increase the CloudFront TTL values in the cache behavior settings. Increasing the Time To Live (TTL) values in the cache behavior settings allows CloudFront to cache objects for a longer period, reducing the number of requests that need to go to the origin server. This can significantly improve the cache hit ratio and reduce the load on the origin server. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html
