A company is designing a tightly coupled high-performance computing (HPC) environment in AWS and needs to optimize networking and storage for HPC. Which two solutions together meet these requirements? (Choose two.)

For tightly coupled HPC workloads, low-latency networking and high-throughput storage are critical. Elastic Fabric Adapter (EFA) is a network interface for Amazon EC2 instances that enables high-performance computing (HPC) and machine learning applications to achieve lower and more consistent latency and higher throughput than traditional TCP networking. Amazon FSx for Lustre is a high-performance file system optimized for HPC workloads, providing sub-millisecond latencies and high throughput. Configuring it with scratch storage is suitable for temporary, high-performance data processing. AWS Global Accelerator is for improving global application availability and performance by routing traffic through the AWS global network, not for optimizing intra-region HPC networking. Amazon CloudFront is a content delivery network (CDN) for caching web content, irrelevant for HPC internal networking. AWS Elastic Beanstalk is an orchestration service for deploying and managing web applications, not a core component for HPC infrastructure optimization.
