Question 90 of 100 | ← Chapter 11

Q790. A company is migrating a large amount of data from on-premises storage to AWS. Windows, Mac, and Linux based Amazon EC2 instances in the same AWS Region will access the data by using SMB and NFS storage protocols. The company will access a portion of the data routinely. The company will access the remaining data infrequently.The company needs to design a solution to host the data.Which solution will meet these requirements with the LEAST operational overhead?

Correct Answer: C. Create an Amazon S3 bucket that uses S3 Intelligent-Tiering. Migrate the data to the S3 bucket by using an AWS Storage Gateway Amazon S3 File Gateway.

Explanation

B OR C.To meet the requirements of hosting a large amount of data that will be accessed by Windows, Mac, and Linux based Amazon EC2 instances using SMB and NFS storage protocols, with routine and infrequent access, while minimizing operational overhead, the solution with the least operational overhead is:C. Create an Amazon S3 bucket that uses S3 Intelligent-Tiering. Migrate the data to the S3 bucket by using an AWS Storage Gateway Amazon S3 File Gateway.Creating an Amazon S3 bucket using S3 Intelligent-Tiering is a cost-effective and operationally efficient solution for hosting the data. S3 Intelligent-Tiering automatically moves objects between two access tiers: frequent access and infrequent access, based on their access patterns. This ensures that frequently accessed data is readily available, while infrequently accessed data is stored in a more cost-effective tier.Using an AWS Storage Gateway Amazon S3 File Gateway allows seamless integration between on-premises environments and the S3 bucket. It provides a file interface for the EC2 instances to access the data using SMB and NFS protocols. The data is migrated to the S3 bucket through the Storage Gateway, simplifying the migration process.Here's why the other options are not the least operationally overhead choices:A. Creating an Amazon EFS volume with EFS Intelligent-Tiering: While EFS provides file storage, using EFS Intelligent-Tiering for data that will be accessed routinely and infrequently may not be the most cost-effective option. It requires managing the EFS volume and configuring the tiering policy, which can introduce additional operational overhead.B. Creating an Amazon FSx for ONTAP instance with auto tiering policy: FSx for ONTAP is a fully managed file storage service, but it may introduce more operational overhead compared to other options. Setting up and managing an FSx for ONTAP instance and configuring the auto tiering policy can add complexity and administrative effort.D. Creating an Amazon FSx for OpenZFS file system: FSx for OpenZFS is another fully managed file storage service, but it may have more operational overhead compared to other options. It requires managing the FSx for OpenZFS file system and may involve more complex configuration and maintenance tasks.Therefore, the solution that meets the requirements with the least operational overhead is:C. Create an Amazon S3 bucket that uses S3 Intelligent-Tiering. Migrate the data to the S3 bucket by using an AWS Storage Gateway Amazon S3 File Gateway.
