S3 Lifecycle Policy for Infrequently Accessed Data

• ✓ A.Use S3 Intelligent-Tiering to automatically optimize storage costs.
• B.Use S3 One Zone-IA for all data after 30 days to reduce costs.
• ✓ C.Create a lifecycle policy to transition objects to S3 Glacier Deep Archive after 90 days.
• ✓ D.Create a lifecycle policy to transition objects to S3 Standard-IA after 30 days.
• E.Use S3 Standard storage for all data to ensure high performance.

Why A: The correct actions are A, C, D. Option A: S3 Intelligent-Tiering automatically moves data between tiers based on access patterns, optimizing costs for data with changing access patterns. Option C: A lifecycle policy to transition objects to S3 Glacier Deep Archive after 90 days is appropriate for data that is rarely accessed after the initial 30 days. Option D: A lifecycle policy to transition objects to S3 Standard-IA after 30 days is a good cost-saving measure for data that is accessed infrequently after the first 30 days. Option B is incorrect because S3 One Zone-IA is not durable enough for analytics data that may need availability, and it does not automatically optimize costs like Intelligent-Tiering. Option E is incorrect because using S3 Standard for all data would be more expensive than using the lifecycle policies or Intelligent-Tiering.

• A.Move all objects to S3 Intelligent-Tiering immediately.
• B.Delete objects older than 30 days using S3 Lifecycle expiration.
• C.Manually change the storage class of each object to S3 Glacier Deep Archive after 30 days.
• ✓ D.Configure an S3 Lifecycle policy to transition objects to S3 Standard-IA after 30 days, then to S3 Glacier Deep Archive after 90 days.

Why D: Option D is correct because it uses an S3 Lifecycle policy to automatically transition objects to S3 Standard-IA after 30 days (when access drops), then to S3 Glacier Deep Archive after 90 days for long-term cold storage. This balances cost and access needs: Standard-IA offers lower storage cost than Standard for infrequent access, and Glacier Deep Archive provides the lowest cost for rarely accessed data after 90 days. The policy automates the transitions, avoiding manual effort and ensuring cost optimization without data loss.

• ✓ A.Standard for 30 days, then transition to Standard-IA for 90 days, then to Glacier Deep Archive.
• B.Standard for 30 days, then transition to One Zone-IA for 90 days, then to Glacier Deep Archive.
• C.Standard for 120 days, then transition to Glacier Deep Archive.
• D.Standard for 30 days, then transition to Glacier for the remaining life.

Why A: Option A is correct because it aligns the storage class transitions precisely with the access patterns: Standard for frequent access (first 30 days), Standard-IA for infrequent access (next 90 days), and Glacier Deep Archive for long-term retention (after 120 days). This minimizes cost by avoiding paying for premium storage when data is rarely accessed, while still meeting the 7-year compliance requirement at the lowest possible storage cost.

• A.Transition objects to S3 Standard-IA after 30 days, and to S3 Glacier after 60 days. Delete after 7 years.
• B.Transition objects to S3 Glacier Deep Archive after 30 days, and delete after 7 years.
• C.Transition objects to S3 One Zone-IA after 30 days, and to S3 Glacier Deep Archive after 90 days. Delete after 7 years.
• ✓ D.Transition objects to S3 Standard-IA after 30 days, and to S3 Glacier Deep Archive after 90 days. Delete after 7 years.

Why D: Option D is correct because it aligns the lifecycle transitions with the access patterns: frequent access for the first 30 days (S3 Standard), occasional access for the next 60 days (S3 Standard-IA), and rare access after 90 days (S3 Glacier Deep Archive, the lowest-cost storage class for long-term retention). The deletion after 7 years meets compliance requirements while minimizing costs by using progressively cheaper storage classes.

• ✓ A.Configure a lifecycle policy to delete incomplete multipart uploads after 7 days
• B.Enable S3 Object Lock to prevent deletion
• ✓ C.Create a lifecycle policy to transition objects to S3 Standard-IA after 90 days
• D.Enable S3 Versioning to keep multiple versions
• E.Enable Requester Pays on the bucket

Why A: Option A is correct because configuring a lifecycle policy to delete incomplete multipart uploads after 7 days prevents orphaned parts from incurring storage costs. Option C is correct because creating a lifecycle policy to transition objects to S3 Standard-IA after 90 days reduces storage costs for infrequently accessed data. Option B is incorrect because S3 Object Lock is used for compliance and retention, not cost optimization. Option D is incorrect because enabling S3 Versioning can increase storage costs by retaining multiple versions of objects. Option E is incorrect because enabling Requester Pays shifts the cost of requests and data transfer to the requester, but does not optimize storage costs for the company.
