Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 648
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A weather forecasting company needs to process hundreds of gigabytes of data with sub-millisecond latency. The company has a high performance computing (HPC) environment in its data center and wants to expand its forecasting capabilities.

A solutions architect must identify a highly available cloud storage solution that can handle large amounts of sustained throughput. Files that are stored in the solution should be accessible to thousands of compute instances that will simultaneously access and process the entire dataset.

What should the solutions architect do to meet these requirements?

  • A. Use Amazon FSx for Lustre scratch file systems.
  • B. Use Amazon FSx for Lustre persistent file systems.
  • C. Use Amazon Elastic File System (Amazon EFS) with Bursting Throughput mode.
  • D. Use Amazon Elastic File System (Amazon EFS) with Provisioned Throughput mode.

Selected Answer: B
Amazon FSx for Lustre is a fully managed file system optimized for high-performance computing (HPC) workloads. It provides sub-millisecond latency and high throughput, making it ideal for processing large datasets like weather forecasting data. It supports thousands of compute instances accessing the file system simultaneously, ensuring scalability for the company's HPC environment.

A persistent file system is recommended because it provides high durability and availability. Data is replicated within an Availability Zone (AZ) and automatically backed up to Amazon S3, ensuring data is not lost in case of failures. This is critical for a weather forecasting company that needs to ensure data integrity and availability.
