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.)

A
Deploy compute optimized EC2 instances into a cluster placement group.
B
Deploy compute optimized EC2 instances into a partition placement group.
C
Attach the EC2 instances to an Amazon FSx for Lustre file system.
D
Attach the EC2 instances to an Amazon FSx for OpenZFS file system.
E
Attach the EC2 instances to an Amazon FSx for NetApp ONTAP file system.

Explanation
Correct Answers: A and E
A. Deploy compute optimized EC2 instances into a cluster placement group. - This is correct because cluster placement groups provide low-latency, high-bandwidth network connectivity between instances within a single Availability Zone, which is essential for latency-sensitive HPC workloads.
E. Attach the EC2 instances to an Amazon FSx for NetApp ONTAP file system. - This is correct because FSx for NetApp ONTAP provides multi-protocol access (NFS, SMB, iSCSI) and is designed for high-performance workloads with low latency requirements. It supports both NFS and SMB protocols simultaneously.
Why other options are incorrect:
B. Deploy compute optimized EC2 instances into a partition placement group. - Partition placement groups are designed for distributed workloads that need to be isolated from failures in other partitions, not specifically for low-latency HPC workloads. Cluster placement groups provide better latency performance.
C. Attach the EC2 instances to an Amazon FSx for Lustre file system. - FSx for Lustre is optimized for high-performance computing and machine learning workloads, but it only supports the Lustre protocol, not NFS and SMB multi-protocol access as required.
D. Attach the EC2 instances to an Amazon FSx for OpenZFS file system. - FSx for OpenZFS provides NFS access but does not support SMB protocol, so it cannot provide the required multi-protocol access.
Key Points:
- Cluster Placement Groups provide the lowest latency network connectivity between EC2 instances
- FSx for NetApp ONTAP is the only FSx option that supports both NFS and SMB protocols simultaneously
- The combination of cluster placement groups for compute instances and FSx for NetApp ONTAP for storage meets all requirements with minimal latency
