Question 6 of 100 | ← Chapter 15

Q1106. A company is building a cloud storage and sharing application for photos. Users can upload photos from their computers and mobile phones to be stored durably in the cloud. After photos are uploaded, most are shared and downloaded frequently for the first 40-90 days. The photos are generally accessed less often after 90 days, but some photos maintain a high access rate. The application initially stores photos in Amazon S3 Standard.A solutions architect needs to reduce the application's operational costs without sacrificing user experience or data durability.Which strategy should the solutions architect use to meet these requirements MOST cost-effectively?

Correct Answer: C. Define an S3 Lifecycle rule to transition objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 65 days.

Explanation

To meet the company's requirements for reducing operational costs while maintaining user experience and data durability for a cloud storage and sharing application, the solutions architect should use the following strategy:C. Define an S3 Lifecycle rule to transition objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 65 days.Analysis:User Experience and Data Durability:The application needs to maintain user experience and data durability. Therefore, the storage solution should provide high availability and durability.Cost Reduction:The company aims to reduce operational costs. This means choosing a storage class that balances cost and performance based on the access patterns of the photos.Access Patterns:Photos are frequently accessed for the first 40-90 days after being uploaded. After 90 days, most photos are accessed less often, but some maintain a high access rate.Evaluation of Options:A. Define an S3 Lifecycle rule to transition objects to S3 Intelligent-Tiering immediately:S3 Intelligent-Tiering automatically optimizes costs by moving data between S3 Standard and S3 Infrequent Access (IA) based on access patterns.However, it has a monitoring and evaluation period of 30 days before transitioning objects, which might not align perfectly with the immediate 40-90 days access pattern. Additionally, it may not provide the most cost-effective solution for objects that maintain a high access rate after 90 days.B. Define an S3 Lifecycle rule to transition objects from S3 Standard to S3 Glacier Deep Archive after 90 days:S3 Glacier Deep Archive is the lowest-cost storage class but is optimized for data that is rarely accessed and retrieved quickly only when needed.It does not align well with the requirement to maintain user experience for photos that may still be accessed after 90 days.C. Define an S3 Lifecycle rule to transition objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 65 days:S3 Standard-IA offers a lower cost than S3 Standard for objects that are accessed less frequently. Transitioning objects to S3 Standard-IA after 65 days (within the 40-90 day frequent access period) allows for cost savings while still accommodating the potential for some photos to be accessed more frequently after 90 days.It provides a balance between cost and performance, maintaining user experience for frequently accessed photos and reducing costs for less frequently accessed ones. D. Define an S3 Lifecycle rule to transition objects from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 90 days:S3 One Zone-IA is similar to S3 Standard-IA but stores data in a single Availability Zone for lower costs. However, it reduces data durability and availability compared to S3 Standard-IA, which may not meet the requirement for maintaining data durability.Conclusion:Option C is the most cost-effective strategy that meets the company's requirements. It transitions objects to S3 Standard-IA after 65 days, balancing cost and performance based on the access patterns of the photos. This allows for cost savings while maintaining user experience and data durability.
