AWS Certified Solutions Architect – Associate (SAA-C02) — Question 16

A company runs an application in a branch office within a small data closet with no virtualized compute resources. The application data is stored on an NFS volume. Compliance standards require a daily offsite backup of the NFS volume.
Which solution meets these requirements?

Answer options

• A. Install an AWS Storage Gateway file gateway on premises to replicate the data to Amazon S3.
• B. Install an AWS Storage Gateway file gateway hardware appliance on premises to replicate the data to Amazon S3.
• C. Install an AWS Storage Gateway volume gateway with stored volumes on premises to replicate the data to Amazon S3.
• D. Install an AWS Storage Gateway volume gateway with cached volumes on premises to replicate the data to Amazon S3.

Correct answer: B

Explanation

The correct answer is B because a hardware appliance for the AWS Storage Gateway file gateway can efficiently handle file storage and replicate the NFS data to Amazon S3, which is necessary for compliance. Option A does not specify a hardware appliance, which may not meet the performance needs. Options C and D involve volume gateways that are not suitable for NFS data storage, making them incorrect for this scenario.
