AWS Certified Solutions Architect – Associate (SAA-C03) — Question 464

A company is looking for a solution that can store video archives in AWS from old news footage. The company needs to minimize costs and will rarely need to restore these files. When the files are needed, they must be available in a maximum of five minutes.

What is the MOST cost-effective solution?

Answer options

• A. Store the video archives in Amazon S3 Glacier and use Expedited retrievals.
• B. Store the video archives in Amazon S3 Glacier and use Standard retrievals.
• C. Store the video archives in Amazon S3 Standard-Infrequent Access (S3 Standard-IA).
• D. Store the video archives in Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA).

Correct answer: A

Explanation

Amazon S3 Glacier with Expedited retrievals is the most cost-effective option because it provides low-cost archive storage and meets the 5-minute recovery time objective by delivering data in 1-5 minutes. Standard retrievals in S3 Glacier take 3-5 hours, which fails the 5-minute requirement. While S3 Standard-IA and S3 One Zone-IA provide faster retrieval times, their storage costs are much higher than S3 Glacier, making them less cost-effective for rarely accessed archives.
