A high-traffic static website is hosted on Amazon S3 with a CloudFront distribution that currently has a default TTL of 0 seconds. The company wants to add caching to improve performance but must ensure stale content is not served for more than a few minutes after a deployment. Which combination of caching methods should a solutions architect implement? (Choose two.)

To balance caching for performance with rapid content updates, a multi-layered approach is best. Setting the CloudFront default TTL to 2 minutes ensures that content is cached at the edge for a short period, improving performance for frequently accessed items while limiting the window for stale content. Adding a Cache-Control: max-age=24h directive to S3 objects allows browsers and CloudFront to cache content for a longer duration, reducing origin requests. However, to prevent stale content from being served for 24 hours after a deployment, a CloudFront invalidation must be performed for changed files. This clears the edge caches immediately, ensuring users receive the latest content. Setting a default TTL on the S3 bucket is not a direct caching mechanism for CloudFront or browsers. A Cache-Control: private directive prevents caching by shared caches
