AWS Certified Solutions Architect Professional SAP-C02 Practice Question

A risk-analytics team launches a short-lived, 10,000-node Monte Carlo simulation on EC2 Spot instances in a single AWS Region. During the 30-minute run each node concurrently creates, reads, and deletes millions of 2 MB files. The application requires POSIX semantics, sub-millisecond latency, and an aggregate throughput that can scale to hundreds of GB/s. After the simulation finishes, results are copied to Amazon S3 and the scratch storage can be discarded. To maximize performance and pay only for storage used during the job, which AWS storage option should the solutions architect choose?

  • Store intermediate data in an Amazon S3 Express One Zone directory bucket that is co-located with the compute Availability Zone.

  • Create an Amazon FSx for Lustre file system using the Scratch 2 deployment type with the SSD storage class, mount it on all compute nodes, and delete the file system when the simulation completes.

  • Deploy an Amazon FSx for Lustre Persistent 2 file system with 1,000 MB/s-per-TiB throughput and SSD storage class, keeping it online between runs.

  • Provision an Amazon EFS Regional file system in Elastic throughput mode and General Purpose performance mode for the cluster.
