AWS Certified Solutions Architect – Associate (SAA-C03) — Question 750

A company is designing a tightly coupled high performance computing (HPC) environment in the AWS Cloud. The company needs to include features that will optimize the HPC environment for networking and storage.

Which combination of solutions will meet these requirements? (Choose two.)

Answer options

• A. Create an accelerator in AWS Global Accelerator. Configure custom routing for the accelerator.
• B. Create an Amazon FSx for Lustre file system. Configure the file system with scratch storage.
• C. Create an Amazon CloudFront distribution. Configure the viewer protocol policy to be HTTP and HTTPS.
• D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances.
• E. Create an AWS Elastic Beanstalk deployment to manage the environment.

Correct answer: B, D

Explanation

Amazon FSx for Lustre with scratch storage provides high-performance, cost-effective temporary storage optimized for processing-heavy HPC workloads. Elastic Fabric Adapter (EFA) is a network interface for Amazon EC2 instances that enables low-latency inter-node communication, which is critical for tightly coupled HPC applications. Other options like AWS Global Accelerator, CloudFront, and Elastic Beanstalk do not address the specific low-latency networking and high-throughput storage requirements of HPC workloads.
