Q741. A company uses Amazon FSx for NetApp ONTAP in its primary AWS Region for CIFS and NFS file shares. Applications that run on Amazon EC2 instances access the file shares. The company needs a storage disaster recovery (DR) solution in a secondary Region. The data that is replicated in the secondary Region needs to be accessed by using the same protocols as the primary Region.Which solution will meet these requirements with the LEAST operational overhead?

Correct Answer: C. Create an FSx for ONTAP instance in the secondary Region. Use NetApp SnapMirror to replicate data from the primary Region to the secondary Region.

Explanation

To meet the requirements of implementing a storage disaster recovery (DR) solution for Amazon FSx for NetApp ONTAP file shares in a secondary AWS Region, while ensuring that the replicated data can be accessed using the same protocols as the primary Region with the least operational overhead, the solution that would best fit these requirements is:C. Create an FSx for ONTAP instance in the secondary Region. Use NetApp SnapMirror to replicate data from the primary Region to the secondary Region.Option C, creating an FSx for ONTAP instance in the secondary Region and using NetApp SnapMirror to replicate data from the primary Region to the secondary Region, would meet the requirements with the least operational overhead.Amazon FSx for NetApp ONTAP provides fully managed, highly available file storage that is compatible with both CIFS and NFS protocols. By creating an FSx for ONTAP instance in the secondary Region, you can establish a DR solution that replicates the data from the primary Region.NetApp SnapMirror is a data replication technology that is specifically designed for NetApp ONTAP storage systems. It enables efficient, block-level replication of data between primary and secondary systems. By utilizing SnapMirror, you can replicate the data from the primary FSx for ONTAP instance to the secondary FSx for ONTAP instance in the secondary Region.This solution ensures that the replicated data in the secondary Region can be accessed using the same protocols (CIFS and NFS) as the primary Region, allowing applications running on Amazon EC2 instances to seamlessly access the file shares.Option A, using AWS Lambda to copy the data to an Amazon S3 bucket and replicating the bucket to the secondary Region, may involve more operational overhead compared to option C. It requires developing and managing a Lambda function, handling data transfer to S3, and configuring cross-Region replication for the S3 bucket. Additionally, accessing the replicated data using the same protocols as the primary Region would not be as straightforward as with an FSx for ONTAP solution.Option B, creating backups of the FSx for ONTAP volumes using AWS Backup, copying the volumes to the secondary Region, and creating a new FSx for ONTAP instance from the backup, may involve more operational overhead compared to option C. It requires managing backups, copying volumes, and restoring them in the secondary Region. This approach may not provide real-time replication and may introduce additional complexities in managing backups and restoring from them.Option D, creating an Amazon Elastic File System (Amazon EFS) volume, migrating the current data to the volume, and replicating the volume to the secondary Region, may not be the most suitable solution for this requirement. While Amazon EFS is a managed NFS file system, it is not specifically designed to replicate data between Regions in the same manner as FSx for ONTAP with SnapMirror. Implementing cross-Region replication with EFS may involve additional complexities and operational overhead.Therefore, the most suitable solution that meets the requirements with the least operational overhead is C: Create an FSx for ONTAP instance in the secondary Region. Use NetApp SnapMirror to replicate data from the primary Region to the secondary Region. This solution provides a highly available and efficient data replication mechanism while ensuring that the replicated data can be accessed using the same protocols as the primary Region.
