Explanation:

To increase the cache hit ratio and reduce origin load:

Origin Shield (Option A) acts as an additional caching layer between the CloudFront edge locations and your origin. This consolidates requests to the origin, significantly improving the cache hit ratio and reducing the load on the origin server.
Increase TTL values (Option E) ensures that objects remain in the CloudFront cache for a longer period of time. This increases the likelihood that a request will be served from the cache rather than being forwarded to the origin.

Option B is for security. Option C is for high availability. Option D improves performance (bandwidth) but doesn't necessarily improve the hit ratio itself.

Question 30. A SysOps administrator notices that the cache hit ratio for an Amazon CloudFront distribution is less than 10%. The SysOps administrator needs to increase the cache hit ratio for the distribution, improve network performance, and reduce the load on the origin. Which combination of actions should the SysOps administrator take to meet these requirements? (Choose two.)
