Question 17 of 75 | ← Chapter 1

Q92. An adventure company has launched a new feature on its mobile app. Users can use the feature to upload their hiking and rafting photos and videos anytime. The photos and videos are stored in Amazon S3 Standard storage in an S3 bucket and are served through Amazon CloudFront. The company needs to optimize the cost of the storage.A solutions architect discovers that most of the uploaded photos and videos are accessed infrequently after 30 days. However, some of the uploaded photos and videos are accessed frequently after 30 days. The solutions architect needs to implement a solution that maintains millisecond retrieval availability of the photos and videos at the lowest possible cost.Which solution will meet these requirements?

• A. Configure S3 Intelligent-Tiering on the S3 bucket. ✓
• B. Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.
• C. Replace Amazon S3 with an Amazon Elastic File System (Amazon EFS) file system that is mounted on Amazon EC2 instances.
• D. Add a Cache-Control: max-age header to the S3image objects and S3video objects. Set the header to 30 days.

Correct Answer: A. Configure S3 Intelligent-Tiering on the S3 bucket.

Explanation

To optimize the cost of storageTo optimize the cost of storage while maintaining millisecond retrieval availability for infrequently accessed photos and videos, the solution that meets these requirements is: A. Configure S3 Intelligent-Tiering on the S3 bucket. S3 Intelligent-Tiering is a storage class that automatically moves objects between two access tiers: frequent access and infrequent access. It uses machine learning to analyze access patterns and moves objects that haven't been accessed for a while to the infrequent access tier, while maintaining millisecond retrieval availability. This allows you to save costs on storage while ensuring quick access when needed.Option B is not correct as it only moves data to S3 Glacier Deep Archive after 30 days, which would still require additional steps to retrieve the data. Option C is not correct because Amazon Elastic File System (Amazon EFS) is a file storage service for use with Amazon EC2 instances, it does not provide a cost-effective solution for storing and retrieving large amounts of data. Option D is not correct because adding a Cache-Control: max-age header only controls the caching behavior of the objects and does not address the cost optimization requirements.
