A CloudFront distribution has a cache hit ratio below 10%. You want to boost the cache hit rate, speed up delivery, and reduce origin strain. Which combination of actions will help? (Choose two.)

Enabling CloudFront Origin Shield creates an additional caching layer between your CloudFront edge caches and your origin. This significantly improves cache hit ratios by consolidating requests to your origin, reducing the load on your origin, and improving content delivery speed. Increasing the TTL (Time To Live) values in the cache behavior tells CloudFront to store objects in its edge caches for a longer duration. This directly boosts the cache hit rate because subsequent requests for the same content will be served from the cache instead of going to the origin, thereby speeding up delivery and reducing origin strain. Requiring HTTPS-only is a security best practice but does not directly impact cache hit ratio. Adding a secondary origin with failover improves availability but doesn't inherently increase the cache hit rate. Turning on automatic compression reduces object size, which can speed up delivery, but doesn't directly increase the cache hit ratio for existing objects.
