SAA-C03 Q135 · Storage

Question

A company uses an Amazon S3 bucket as its data lake storage platform. The S3 bucket contains a massive amount of data that is accessed randomly by multiple teams and hundreds of applications. The company wants to reduce the S3 storage costs and provide immediate availability for frequently accessed objects. What is the MOST operationally efficient solution that meets these requirements?

Accepted Answer

**Answer A: S3 Intelligent-Tiering via Lifecycle rule** is correct for these reasons:

1. **Random access patterns**: The data is accessed randomly by multiple teams and hundreds of applications. This means access patterns are **unpredictable** — the ideal scenario for S3 Intelligent-Tiering, which automatically monitors access patterns and moves objects between tiers.

2. **Immediate availability**: S3 Intelligent-Tiering guarantees **millisecond access latency** for all tiers (Frequent Access, Infrequent Access, and Archive Instant Access). Objects are never 'frozen' — they're always immediately retrievable.

3. **Cost reduction**: S3 Intelligent-Tiering automatically moves objects that haven't been accessed for 30 days to the Infrequent Access tier (up to 40% savings), and after 90 days
