Question 59 of 100 | ← Chapter 13

Q959. A social media company has workloads that collect and process data.The workloads store the data in on- premises NFS storage.The data store cannot scale fast enough to meet the company's expanding business needs.The company wants to migrate the current data store to AWS.Which solution will meet these requirements MOST cost-effectively?

• A. Set up an AWS Storage Gateway Volume Gateway. Use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class.
• B. Set up an AWS Storage Gateway Amazon S3 File Gateway. Use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class. ✓
• C. Use the Amazon Elastic File System (Amazon EFS) Standard-Infrequent Access (Standard-lA) storage class. Activate the infrequent access lifecycle policy.
• D. Use the Amazon Elastic File System (Amazon EFS) One Zone-lnfrequent Access(One Zone-lA) storage class. Activate the infrequent access lifecycle policy.

Correct Answer: B. Set up an AWS Storage Gateway Amazon S3 File Gateway. Use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class.

Explanation

Cost-Effective: S3 File Gateway is designed to present S3 storage as a file system, making it a cost- effective way to migrate NFS data. It avoids the need for significant application changes and leverages the cost savings of S3.Scalability: S3 is highly scalable, allowing the company to easily expand its data store as its business grows.Lifecycle Policies: S3 Lifecycle policies can automatically transition data between storage classes based on access patterns, further optimizing storage costs.Data Migration: S3 File Gateway simplifies data migration from on-premises NFS storage to S3, reducing the complexity and effort involved.While Volume Gateway (option A) is a good option for block-level storage, it's not the most cost-effective solution for file-based NFS data. EFS (options C and D) is a managed file system, but it's not designed for migrating on-premises NFS data and might require significant application changes.S3 File Gateway is the best fit for this scenario because it provides a cost-effective way to present S3 storage as a file system, allowing the company to migrate its NFS data without major application changes.
