A company stores millions of images in Amazon S3. The access patterns are unpredictable; some images are accessed daily, while others are not accessed for months. The company wants to optimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should they use?

Answer options:

S3 Standard

S3 Standard-Infrequent Access (S3 Standard-IA)

S3 Intelligent-Tiering

S3 Glacier Flexible Retrieval

How to approach this question

Match 'unpredictable access patterns' and 'no retrieval fees' to S3 Intelligent-Tiering.

Full Answer

C.S3 Intelligent-Tiering✓ Correct

S3 Intelligent-Tiering

Amazon S3 Intelligent-Tiering is the only cloud storage class that delivers automatic cost savings by moving objects between four access tiers based on changing access patterns, without performance impact or retrieval fees.

Choosing Standard-IA, forgetting that it charges a per-GB retrieval fee.
