Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 658 discussion

You talked avout smb and nfs, you talked fsx netapp ontap C is wrong because lustre is a POSIX fs

A Because HPC equivalent in AWS is EC2. Cluster placement for low-latency: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html E: ONTAP gives NFS and SMB which is required AE is correct B does not solve low latency requirements C No support for NFS and SMB D OpenZFS is not required

I got baited into quickly going for Lustre after reading, but forgot it doesn't not support NFS/SMB.

Amazon FSx for Lustre does not support SMB. So it's A,E

A because cluster placement group means low latency, and D because OpenZFS has less latency compared to FSx for NetApp ONTAP. See https://aws.amazon.com/fsx/when-to-choose-fsx/ FSx for OpenZFS can handle SMB and NFS. Despite that for onprem NAS appliances the aws Recommended Amazon FSx file system would be FSx for NetApp ONTAP, I still choose FSx for OpenZFS for the lower latency.

LEAST latency = cluster placement group Amazon FSx for Lustre = SMB Amazon FSx for OpenZFS = NFS Amazon FSx for NetApp ONTAP = NFS, SMB, iSCSI So, answer are A and E

A becase cluster placement group means low latency. E

HPC, NFS, SMB = FSx for NetApp ONTAP file system HPC, latency-sensitive = cluster placement group

AE https://aws.amazon.com/fsx/when-to-choose-fsx/

I don't think FSx for Lustre supports SMB. At least I could not find anything in the documentation. However, FSx for ONTAP delivers NFS and SMB support.

To meet the requirements of migrating latency-sensitive HPC workloads with multi-protocol access (NFS and SMB) to AWS with minimal latency, the following solutions would be the most appropriate: A. Deploy compute optimized EC2 instances into a cluster placement group. C. Attach the EC2 instances to an Amazon FSx for Lustre file system.

https://aws.amazon.com/fsx/netapp-ontap/features/#:~:text=Amazon%20FSx%20for%20NetApp%20ONTAP%20provides%20access%20to%20shared%20file,access)%20to%20the%20same%20data. "Amazon FSx for NetApp ONTAP provides access to shared file storage over all versions of the Network File System (NFS) and Server Message Block (SMB) protocols, and also supports multi-protocol access (i.e. concurrent NFS and SMB access) to the same data."

Option A: A cluster placement group provides low-latency and high-bandwidth connectivity between instances. This is particularly beneficial for high-performance computing workloads that are latency-sensitive. Instances within a cluster placement group are placed in close proximity to each other within the same Availability Zone. Option C: Amazon FSx for Lustre is a high-performance file system optimized for fast access to data. It is well-suited for high-performance computing workloads. It provides low-latency access to data and supports the NFS protocol.
