Question #1488

A company stores customer transaction data in an Amazon S3 bucket, which is accessed irregularly for various analytics tasks. The access patterns are unpredictable, and the company seeks to minimize storage costs without manual intervention. Which solution best addresses these requirements?

A

Use S3 replication to copy objects to S3 Glacier Flexible Retrieval after 30 days.

B

Configure S3 Lifecycle policies to transition objects from S3 Standard to S3 Standard-Infrequent Access after 30 days.

C

Implement S3 Lifecycle policies to move objects from S3 Standard to S3 Intelligent-Tiering.

D

Utilize S3 Inventory reports to identify rarely accessed objects and manually move them to S3 Intelligent-Tiering.

Explanation

Option C is correct because S3 Intelligent-Tiering automatically monitors access patterns and moves objects between Frequent Access and Infrequent Access tiers, minimizing costs without manual effort. This aligns with the requirement to handle unpredictable access patterns and avoid manual intervention.

Option A is incorrect because S3 replication to Glacier involves manual setup and is designed for archival storage, not cost optimization for irregular analytics access. Option B is suboptimal because S3 Standard-IA requires a minimum storage duration (30 days) and incurs retrieval fees if accessed frequently, which may not suit unpredictable access. Option D is invalid because manual intervention contradicts the requirement for automation.

Key Points:
- S3 Intelligent-Tiering is designed for unpredictable access patterns.
- It automatically optimizes storage costs without manual actions.
- Other options either require manual effort or are less cost-effective for irregular access.

Answer

The correct answer is: C
