Question 340
A website serves global viewers but the origin is regional and static images load slowly. Which evidence BEST validates the recommended AWS choice?
Explanation
Correct Answer
Remote clients demonstrate expected cache hits for the images. This result is directly relevant because CloudFront caches eligible content at edge locations to reduce origin fetch distance. The underlying AWS decision is: Use Amazon CloudFront as a content delivery network. The ongoing safeguard is: Tune TTLs and protect private or personalized content from incorrect caching.
Incorrect Answers

The answer that meets the requirement is: Remote clients demonstrate expected cache hits for the images.
A public IP by itself does not replace the required VPC Internet routing path. In this question, however, cloudFront caches eligible content at edge locations to reduce origin fetch distance. The answer that meets the requirement is: Remote clients demonstrate expected cache hits for the images.
Network ACLs are stateless subnet controls, distinct from resource-level security groups. In this question, however, cloudFront caches eligible content at edge locations to reduce origin fetch distance. The answer that meets the requirement is: Remote clients demonstrate expected cache hits for the images.
