A logistics enterprise is migrating its central shipping tracking application to AWS. The application runs on Amazon ECS container instances distributed across three Availability Zones. The storage solution for the application must provide concurrent read/write POSIX-compliant file system access, offer sub-millisecond latency for active shipping manifests, and deliver 99.99% availability. Additionally, compliance mandates that the manifests must be replicated to a secondary AWS Region with a Recovery Point Objective (RPO) of 15 minutes. Which combination of storage configurations will meet these requirements? (Select TWO.)
- Deploy Amazon Elastic File System (Amazon EFS) with the Standard storage class to provide shared, multi-Availability Zone storage.Cevap
- Configure Amazon EFS Replication to automatically replicate the file system to the secondary AWS Region.Cevap
- CProvision Amazon EBS gp3 volumes with Multi-Attach enabled, and mount them across all ECS container instances in the three Availability Zones.
- DDeploy Amazon EFS using the One Zone storage class and use AWS Backup to schedule replication to the secondary AWS Region.
- EStore the active manifests in an Amazon S3 bucket and configure an S3 Lifecycle policy to transition them to the S3 Glacier Instant Retrieval storage class in the secondary AWS Region.
Cevap
Deploying Amazon EFS using the Standard storage class and configuring Amazon EFS Replication to the secondary AWS Region.
Deploying Amazon EFS using the Standard storage class provides a highly available, multi-AZ, POSIX-compliant shared file system supporting concurrent access from multiple ECS instances with sub-millisecond latency. Configuring Amazon EFS Replication automatically replicates the data to a destination region with a typical replication delay of minutes, meeting the 15-minute RPO requirement.

Anahtar Kavram
Amazon EFS replication provides cross-region replication for multi-AZ, POSIX-compliant shared file systems with low RPO targets.
