A company stores millions of images in an Amazon S3 bucket. The access patterns for the images are highly unpredictable; some images are accessed daily, while others are not accessed for months. The company wants to minimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should be used?
Answer options:
A.
S3 Standard
B.
S3 Standard-Infrequent Access (S3 Standard-IA)
C.
S3 Intelligent-Tiering
D.
S3 Glacier Flexible Retrieval
How to approach this question
Match 'unpredictable access patterns' and 'no retrieval fees' with S3 Intelligent-Tiering.
Full Answer
C.S3 Intelligent-Tiering✓ Correct
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. It is ideal for data with unknown or changing access patterns, and it does not charge retrieval fees.
Common mistakes
Choosing S3 Standard-IA. While cheaper for storage, IA charges per-GB retrieval fees, which can be costly if unpredictable data is suddenly accessed frequently.
