Q751. A company uses an on-premises network-attached storage (NAS) system to provide file shares to its high performance computing (HPC) workloads. The company wants to migrate its latency-sensitive HPC workloads and its storage to the AWS Cloud. The company must be able to provide NFS and SMB multi- protocol access from the file system.Which solution will meet these requirements with the LEAST latency? (Choose two.)

Correct Answer: A. Deploy compute optimized EC2 instances into a cluster placement group., E. Attach the EC2 instances to an Amazon FSx for NetApp ONTAP file system.

Explanation

AE OR AC.Option A, deploying compute optimized EC2 instances into a cluster placement group, is a suitable choice for minimizing latency in HPC workloads. Cluster placement groups provide low-latency networking between the instances within the group, allowing for high-performance communication and reduced latency between instances. By deploying the compute optimized EC2 instances into a cluster placement group, you can take advantage of the optimized networking to minimize latency.Option E, attaching the EC2 instances to an Amazon FSx for NetApp ONTAP file system, is the preferred choice for providing NFS and SMB multi-protocol access with low latency. Amazon FSx for NetApp ONTAP is a high-performance file system designed for enterprise workloads and provides low-latency access to data. By attaching the EC2 instances to an FSx for NetApp ONTAP file system, you can achieve high-performance storage with minimal latency for your HPC workloads.Option B, deploying compute optimized EC2 instances into a partition placement group, is not the optimal choice for minimizing latency. Partition placement groups provide logical separation but do not offer the same low-latency networking benefits as cluster placement groups. Therefore, it may not provide the least latency for your HPC workloads.Option C, attaching the EC2 instances to an Amazon FSx for Lustre file system, is a high-performance file system but may not provide the least latency for NFS and SMB multi-protocol access compared to Amazon FSx for NetApp ONTAP.Option D, attaching the EC2 instances to an Amazon FSx for OpenZFS file system, is not the most suitable choice for minimizing latency. While Amazon FSx for OpenZFS provides a durable and scalable file system, it may not have the same optimized performance and low latency as Amazon FSx for NetApp ONTAP for HPC workloads.Therefore, the two solutions that will meet the requirements with the least latency are:A. Deploy compute optimized EC2 instances into a cluster placement group.E. Attach the EC2 instances to an Amazon FSx for NetApp ONTAP file system.
