Q723. A solutions architect is designing an application that will allow business users to upload objects to Amazon S3. The solution needs to maximize object durability. Objects also must be readily available at any time and for any length of time. Users will access objects frequently within the first 30 days after the objects are uploaded, but users are much less likely to access objects that are older than 30 days.Which solution meets these requirements MOST cost-effectively?

Correct Answer: B. Store all the objects in S3 Standard with an S3 Lifecycle rule to transition the objects to S3 Standard- Infrequent Access (S3 Standard-IA) after 30 days.

Explanation

Option B, storing all objects in S3 Standard with an S3 Lifecycle rule to transition objects to S3 Standard-IA after 30 days, is the most cost-effective solution while meeting the requirements:- S3 Standard: S3 Standard is the default storage class in Amazon S3 and offers high durability, availability, and performance for frequently accessed objects.- S3 Standard-IA: S3 Standard-Infrequent Access is a lower-cost storage class in Amazon S3 designed for infrequently accessed data. It still provides high durability and availability but at a reduced cost compared to S3 Standard.By storing all objects in S3 Standard initially and transitioning them to S3 Standard-IA after 30 days using an S3 Lifecycle rule, the solution maximizes object durability, ensures objects are readily available at any time, and optimizes costs by moving the objects to a lower-cost storage class when they are less likely to be accessed.Option A, storing objects in S3 Standard with a lifecycle rule to transition to S3 Glacier after 30 days, may provide high durability but is not suitable for readily available access and may introduce retrieval costs and higher latency for accessing objects.Option C, storing objects in S3 Standard with a lifecycle rule to transition to S3 One Zone-IA after 30 days, is less cost-effective compared to Option B. S3 One Zone-IA stores objects in a single availability zone, which may pose a higher risk of data loss compared to S3 Standard-IA.Option D, storing objects in S3 Intelligent-Tiering with a lifecycle rule to transition to S3 Standard-IA after 30 days, may provide some cost optimizations but may not be the most cost-effective solution. S3 Intelligent-Tiering incurs additional costs compared to storing objects directly in S3 Standard.Therefore, the correct solution that meets the requirements most cost-effectively is B: Store all the objects in S3 Standard with an S3 Lifecycle rule to transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days. This solution ensures object durability, availability, and cost optimization by moving objects to a lower-cost storage class after the initial 30-day period.
