AWS Certified SysOps Administrator – Associate — Question 40

A SysOps administrator noticed that the cache hit ratio for an Amazon CloudFront distribution is less than 10%.

Which collection of configuration changes will increase the cache hit ratio for the distribution? (Choose two.)

Answer options

• A. Ensure that only required cookies, query strings, and headers are forwarded in the Cache Behavior Settings.
• B. Change the Viewer Protocol Policy to use HTTPS only.
• C. Configure the distribution to use presigned cookies and URLs to restrict access to the distribution.
• D. Enable automatic compression of objects in the Cache Behavior Settings.
• E. Increase the CloudFront time to live (TTL) settings in the Cache Behavior Settings.

Correct answer: A, E

Explanation

The correct answers, A and E, focus on optimizing the cache by minimizing the number of forwarded items and increasing the TTL, which helps to serve cached content longer. Options B, C, and D do not directly address the cache hit ratio; B changes the protocol, C restricts access, and D pertains to object size rather than cache efficiency.
