Q679. 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? (Select TWO.)

Correct Answer: B. Create an Amazon FSx for Lustre file system. Configure the file system with scratch storage, D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances

Explanation

To optimize a tightly coupled high-performance computing (HPC) environment in the AWS Cloud, the following combination of solutions should be implemented: D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances.B. Create an Amazon FSx for Lustre file system. Configure the file system with scratch storage. Explanation: Option D, launching Amazon EC2 instances and attaching an Elastic Fabric Adapter (EFA) to the instances, is a solution specifically designed to optimize networking performance for HPC workloads. EFA is a network interface that provides low-latency, high-bandwidth communication between EC2 instances. It is particularly well-suited for tightly coupled workloads that require high-performance inter-instance communication. Option B, creating an Amazon FSx for Lustre file system and configuring it with scratch storage, is a solution for optimizing storage performance in an HPC environment. Amazon FSx for Lustre is a fully managed file system that is optimized for HPC workloads. It provides high-performance storage for compute-intensive applications. Option A, creating an accelerator in AWS Global Accelerator and configuring custom routing, is a solution for improving the performance of global applications by using the AWS global network infrastructure. While it can provide benefits for certain use cases, it may not directly optimize the networking and storage performance within a tightly coupled HPC environment. Option C, creating an Amazon CloudFront distribution and configuring the viewer protocol policy to be HTTP and HTTPS, is a solution for content delivery and caching. It is not directly related to optimizing networking and storage performance in an HPC environment. Option E, creating an AWS Elastic Beanstalk deployment to manage the environment, is a solution for deploying and managing web applications. It is not specifically designed for optimizing networking and storage performance in an HPC environment. Therefore, the two solutions that will meet the requirements of optimizing the HPC environment for networking and storage are: D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances.B. Create an Amazon FSx for Lustre file system.
