AWS SAA-C03 · Question 41 · Domain 4.1: Storage Cost Optimization

A company stores millions of images in an Amazon S3 bucket. The images are accessed frequently for the first 30 days, then rarely accessed, but must be kept indefinitely for compliance. The company wants to minimize storage costs without impacting the performance of retrieving new images. <br/><br/>Which S3 lifecycle policy should be implemented?

Answer options:

A.

Transition objects to S3 Glacier Flexible Retrieval after 30 days.

B.

Transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.

C.

Transition objects to S3 One Zone-IA after 30 days.

D.

Use S3 Intelligent-Tiering.

How to approach this question

Match 'rarely accessed but needs fast retrieval' to S3 Standard-IA.

Full Answer

B.Transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.✓ Correct
Transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. It offers the high durability, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee.

Common mistakes

Choosing Glacier, which would break the application if it expects immediate image loads.
