AWS Certified Solutions Architect – Associate (SAA-C03) — Question 146

A solutions architect needs to implement a solution to reduce a company's storage costs. All the company's data is in the Amazon S3 Standard storage class. The company must keep all data for at least 25 years. Data from the most recent 2 years must be highly available and immediately retrievable.
Which solution will meet these requirements?

Answer options

• A. Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive immediately.
• B. Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.
• C. Use S3 Intelligent-Tiering. Activate the archiving option to ensure that data is archived in S3 Glacier Deep Archive.
• D. Set up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years.

Correct answer: B

Explanation

The correct answer is B because it allows the company to keep the most recent 2 years of data in the S3 Standard storage class for immediate access while transitioning older data to S3 Glacier Deep Archive after 2 years, which meets the cost reduction requirement. Options A, C, and D do not meet the requirement of keeping the last 2 years of data highly available and immediately retrievable.
