AWS Certified Solutions Architect – Associate (SAA-C02) — Question 151

A company requires a durable backup storage solution for its on-premises database servers while ensuring on-premises applications maintain access to these backups for quick recovery. The company will use AWS storage services as the destination for these backups. A solutions architect is designing a solution with minimal operational overhead.
Which solution should the solutions architect implement?

Answer options

• A. Deploy an AWS Storage Gateway file gateway on-premises and associate it with an Amazon S3 bucket.
• B. Back up the databases to an AWS Storage Gateway volume gateway and access it using the Amazon S3 API.
• C. Transfer the database backup files to an Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 instance.
• D. Back up the database directly to an AWS Snowball device and use lifecycle rules to move the data to Amazon S3 Glacier Deep Archive.

Correct answer: A

Explanation

The correct answer is A because deploying an AWS Storage Gateway file gateway on-premises allows for seamless integration with Amazon S3, enabling fast access to backups by on-premises applications. Option B, while it involves AWS Storage Gateway, is less efficient for direct file access. Option C requires additional management of an EC2 instance, increasing operational overhead. Option D adds complexity by involving a Snowball device, which is not necessary for regular backup access.
