Q1065. A company is creating a web application that will store a large number of images in Amazon S3. The images will be accessed by users over variable periods of time. The company wants to:Retain all the images.Incur no cost for retrieval.Have minimal management overhead.Have the images available with no impact on retrieval time.Which solution meets these requirements?

Correct Answer: A. Implement S3 Intelligent-Tiering.

Explanation

To determine the best solution for storing a large number of images in Amazon S3 with the specified requirements, let's analyze each option provided:A. Implement S3 Intelligent-Tiering.Advantages: S3 Intelligent-Tiering automatically moves data between access tiers (S3 Standard, S3 Intelligent-Tiering Access, and S3 Glacier Deep Archive) based on usage patterns. This can help in optimizing costs without compromising on performance or access time for frequently accessed data. Relevance: This solution meets the requirements of retaining all images, incurring no cost for retrieval (since frequently accessed data stays in the Standard tier with no retrieval cost), having minimal management overhead (since tiering is automatic), and ensuring images are available with no impact on retrieval time for frequently accessed data.B. Implement S3 storage class analysis.Drawbacks: This is a tool that provides insights into your storage usage patterns but does not itself fulfill the requirement to store data cost-effectively with minimal management overhead and no retrieval costs. C. Implement an S3 Lifecycle policy to move data to S3 Standard-Infrequent Access (S3 Standard-IA).Drawbacks: S3 Standard-IA is cost-effective for infrequently accessed data. However, it incurs retrieval fees, which contradicts the requirement of incurring no cost for retrieval. D. Implement an S3 Lifecycle policy to move data to S3 One Zone-Infrequent Access (S3 One Zone-IA).Drawbacks: S3 One Zone-IA offers cost savings similar to S3 Standard-IA but with data stored in a single Availability Zone. It also incurs retrieval fees, which does not meet the requirement of no retrieval cost.Conclusion:Option A, implementing S3 Intelligent-Tiering, is the best solution that meets all the specified requirements. It automatically optimizes costs based on usage patterns, ensures no retrieval cost for frequently accessed data, requires minimal management overhead, and ensures images are available with no impact on retrieval time for frequently accessed data.答案:A
