Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 75 discussion

answer is C

C Fargat not supported for luster plus "it must support concurrent file access and give good performance." it didn't say HPC

Who decides what the right answer is? I'm confused Most people write one answer but the correct answer looks different

Since AWS Fargate does not support Amazon FSx for Lustre file systems, the best option would be C. Create an Amazon Elastic File System (Amazon EFS) file share and establish an IAM role that allows Fargate to communicate with Amazon EFS.

C is the answer

here is the note from aws: Note Mounting FSx for Lustre on an AWS Fargate launch type isn't supported.

CHATGPT ALSO AGREES WITH C To design a managed storage solution for the company's application that includes high-performance machine learning functionality running on AWS Fargate, the solutions architect should consider Amazon Elastic File System (EFS). Amazon EFS is a managed, scalable, and highly available file system for use with EC2 instances and containers, including Fargate. EFS supports concurrent access to files from multiple Fargate tasks, which is required for high-performance machine learning workloads. Additionally, EFS provides high performance and low latency access to files, which is necessary for machine learning workloads that require fast access to large amounts of data. EFS can be mounted on Fargate containers as a shared file system, enabling multiple containers to access the same files. EFS also provides automatic scaling of storage capacity and throughput, which makes it easy to handle changing workloads and storage requirements.

FSx for Lustre makes it easy and cost-effective to launch and run the popular, high-performance Lustre file system. You use Lustre for workloads where speed matters, such as machine learning, high performance computing (HPC), video processing, and financial modeling.

Q. Can I access my Amazon EFS file system concurrently from my on-premises datacenter servers as well as Amazon EC2 instances? Yes. You can access your Amazon EFS file system concurrently from servers in your on-premises datacenter as well as Amazon EC2 instances in your Amazon VPC. Amazon EFS provides the same file system access semantics, such as strong data consistency and file locking, across all EC2 instances and on-premises servers accessing a file system. https://aws.amazon.com/efs/faq/
