Question 38 of 100 | ← Chapter 12

Q838. 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?

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

To migrate the current on-premises NFS data store to AWS in a cost-effective manner while meeting the company's expanding business needs, the recommended solution is: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.Here's why:Option B suggests setting up an AWS Storage Gateway Amazon S3 File Gateway. The File Gateway provides a way to access data stored in Amazon S3 through a file interface, making it suitable for migrating NFS data to AWS.By using an Amazon S3 Lifecycle policy, you can transition the data to the appropriate storage class based on its access patterns. Amazon S3 offers various storage classes, including Standard, Intelligent-Tiering, Standard-IA (Infrequent Access), One Zone-IA, and Glacier, with different cost structures. By leveraging the lifecycle policy, you can optimize costs by automatically moving less frequently accessed data to lower-cost storage classes.This solution allows the social media company to migrate their current data store to AWS using the AWS Storage Gateway File Gateway, which provides a seamless integration with Amazon S3. It enables scalability and cost-effectiveness by leveraging the lifecycle policy to transition data based on its access patterns.Options A, C, and D do not provide the same level of cost-effectiveness and efficiency for the given scenario.Option A suggests setting up an AWS Storage Gateway Volume Gateway. While this solution provides block storage access to AWS, it may introduce additional complexity and potential costs associated with managing a gateway.Option C suggests using the Amazon EFS Standard-Infrequent Access (Standard-IA) storage class. However, Amazon EFS is a managed file storage service, and the Standard-IA storage class is not directly applicable to the given scenario involving on-premises NFS storage. Therefore, it may not be the most suitable solution for migrating the existing NFS data store.Option D suggests using the Amazon EFS One Zone-Infrequent Access (One Zone-IA) storage class. Similar to Option C, this option does not directly address the migration of on-premises NFS storage to AWS. Additionally, the One Zone-IA storage class lacks the same level of durability and redundancy as the Standard storage class.Therefore, the correct and most cost-effective solution is to set up an AWS Storage Gateway Amazon S3 File Gateway and use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class. This solution ensures a seamless migration of the NFS data store to AWS while optimizing costs through lifecycle management.
