AWS Certified Solutions Architect – Associate (SAA-C03) — Question 615

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.)

Answer options

• 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.

Correct answer: A, E

Explanation

Cluster placement groups place EC2 instances physically close together within an Availability Zone to achieve the lowest possible network latency for HPC workloads, while Amazon FSx for NetApp ONTAP natively supports both NFS and SMB multi-protocol access. Partition placement groups do not optimize for low-latency node-to-node communication, and other FSx options like Lustre or OpenZFS do not support the required concurrent NFS and SMB multi-protocol file access.
