AWS Certified Solutions Architect – Associate (SAA-C02) — Question 449

A media company is evaluating the possibility of moving its systems to the AWS Cloud. The company needs at least 10 TB of storage with the maximum possible
I/O performance for video processing, 300 TB of very durable storage for storing media content, and 900 TB of storage to meet requirements for archival media that is not in use anymore.
Which set of services should a solutions architect recommend to meet these requirements?

Answer options

• A. Amazon Elastic Block Store (Amazon EBS) for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage
• B. Amazon Elastic Block Store (Amazon EBS) for maximum performance, Amazon Elastic File System (Amazon EFS) for durable data storage, and Amazon S3 Glacier for archival storage
• C. Amazon EC2 instance store for maximum performance, Amazon Elastic File System (Amazon EFS) for durable data storage, and Amazon S3 for archival storage
• D. Amazon EC2 instance store for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage

Correct answer: A

Explanation

Amazon Elastic Block Store (Amazon EBS) provides the high-performance block storage required for intensive video processing while ensuring data persistence, unlike ephemeral EC2 instance stores. Amazon S3 offers 99.999999999% durability for active media content at scale, while Amazon S3 Glacier provides the most cost-effective solution for long-term archival needs. Other options either rely on ephemeral instance stores which risk data loss, or use more expensive storage services like Amazon EFS that are not optimized for mass archival storage.
