A company is deploying a new web-based application and needs a storage solution for the Linux application servers.The company wants to create a single location for updates to application data for all instances.The active dataset will be up to 100 GB in size.A solutions architect has determined that peak operations will occur for 3 hours daily and will require a total of 225 MiBps of read throughput.The solutions architect must design a Multi-AZ solution that makes a copy of the data available in another AWS Region for disaster recovery (DR).The DR copy has an RPO of less than 1 hour.

Which solution will meet these requirements?

Deploy a new Amazon Elastic File System (Amazon EFS) Multi-AZ file system. Configure the file system for 75 MiBps of provisioned throughput. Implement replication to a file system in the DR Region.

Deploy a new Amazon FSx for Lustre file system. Configure Bursting Throughput mode for the file system. Use AWS Backup to back up the file system to the DR Region.

Deploy a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume with 225 MiBps of throughput. Enable Multi-Attach for the EBS volume. Use AWS Elastic Disaster Recovery to replicate the EBS volume to the DR Region.

Deploy an Amazon FSx for OpenZFS file system in both the production Region and the DR Region. Create an AWS DataSync scheduled task to replicate the data from the production file system to the DR file system every 10 minutes.

Explanations:

Amazon EFS with Multi-AZ configuration supports high availability and provides the required 225 MiBps read throughput. Provisioned throughput of 75 MiBps allows bursts, meeting peak requirements. EFS replication enables DR with <1-hour RPO.

Amazon FSx for Lustre is optimized for high-performance computing, but Bursting Throughput mode may not meet sustained 225 MiBps. Additionally, AWS Backup lacks <1-hour RPO for cross-region replication.

EBS Multi-Attach provides shared block storage, but does not support Multi-AZ directly, nor does it meet the DR requirement for cross-region replication with an RPO <1 hour.

FSx for OpenZFS with AWS DataSync allows cross-region replication but does not ensure an RPO of less than 1 hour, as DataSync replication intervals are typically scheduled but may not meet stringent RPOs.

    I figure that the answer is:
    Deploy a new Amazon Elastic File System (Amazon EFS) Multi-AZ file system. Configure the file system for 75 MiBps of provisioned throughput. Implement replication to a file system in the DR Region.
