AWS Certified SysOps Administrator – Associate (legacy) — Question 430

What was the recommended use case for S3 Reduced Redundancy storage before its deprecation was planned?

Answer options

• A. It was used to reduce storage costs by providing 500 times the durability of a typical disk drive at lower levels of redundancy.
• B. It was used to reduce storage costs for noncritical data at lower levels of redundancy.
• C. It was used to reduce storage costs by allowing you to destroy any copy of your files outside a specific jurisdiction.
• D. It was used to reduce storage costs for reproducible data at high levels of redundancy in a single facility.

Correct answer: B

Explanation

S3 Reduced Redundancy Storage (RRS) was an Amazon S3 storage class designed to reduce costs for noncritical, reproducible data by storing it with lower levels of redundancy than standard S3. Option B is correct because it accurately captures this intended use case of cost reduction for non-essential assets. The other options are incorrect because they either misstate the durability metrics, falsely claim high redundancy, or invent unrelated compliance features.
