AWS Certified Solutions Architect Professional SAP-C02 Practice Question

Amazon FSx for Lustre is a fully managed, POSIX-compliant, parallel file system that delivers sub-millisecond latencies, millions of IOPS, and terabytes-per-second of aggregate throughput-performance characteristics that meet the simulation's bursty, high-IOPS window. A Lustre file system can be linked to an S3 bucket so that data is automatically imported when first accessed and automatically exported when files are changed or new files are written, eliminating custom copy scripts. EC2 instances simply mount the file system; no file-server cluster or storage management is required.

A Regional Amazon EFS file system provides multi-AZ availability but tops out at tens of gigabytes per second and hundreds of thousands of IOPS; it does not natively import/export to S3 and would require DataSync jobs, adding operational steps. A Multi-Attach io2 EBS volume is limited to 16 Nitro instances and needs a clustered file-system layer plus manual archiving, creating both scalability and management problems. Running an NFS cluster on EC2 with gp3 volumes similarly requires server maintenance and custom data-movement automation. Therefore, creating an Amazon FSx for Lustre file system that is linked to the S3 bucket with automatic import and export enabled is the only option that satisfies performance, scalability, S3 integration, and operational-overhead requirements.
