Amazon SAP-C02 Exam - Topic 1 Question 70 Discussion

A company has built a high performance computing (HPC) cluster in AWS tor a tightly coupled workload that generates a large number of shared files stored in Amazon EFS. The cluster was performing well when the number of Amazon EC2 instances in the cluster was 100. However, when the company increased the cluster size to 1,000 EC2 instances, overall performance was well below expectations.Which collection of design choices should a solutions architect make to achieve the maximum performance from the HPC cluster? (Select THREE.)
A) Ensure the HPC cluster Is launched within a single Availability Zone. and C) Select EC2 Instance types with an Elastic Fabric Adapter (EFA) enabled. and F) Replace Amazon EFS with Amazon FSx for Lustre.
B) Launch the EC2 instances and attach elastic network interfaces in multiples of four.
D) Ensure the cluster Is launched across multiple Availability Zones.
E) Replace Amazon EFS with multiple Amazon EBS volumes in a RAID array.

A company has built a high performance computing (HPC) cluster in AWS tor a tightly coupled workload that generates a large number of shared files stored in Amazon EFS. The cluster was performing well when the number of Amazon EC2 instances in the cluster was 100. However, when the company increased the cluster size to 1,000 EC2 instances, overall performance was well below expectations.

Which collection of design choices should a solutions architect make to achieve the maximum performance from the HPC cluster? (Select THREE.)

Show Suggested Answer Hide Answer
Suggested Answer: A, C, F

A . High performance computing (HPC) workload cluster should be in a single AZ.

C . Elastic Fabric Adapter (EFA) is a network device that you can attach to your Amazon EC2 instances to accelerate High Performance Computing (HPC)

F . Amazon FSx for Lustre - Use it for workloads where speed matters, such as machine learning, high performance computing (HPC), video processing, and financial modeling.

Cluster -- packs instances close together inside an Availability Zone. This strategy enables workloads to achieve the low-latency network performance necessary for tightly-coupled node-to-node communication that is typical of HPC applications.

I practiced a similar question where EFS was a bottleneck, and I think replacing it with FSx for Lustre could really improve performance, so I’d go with option F.

I'm not entirely sure, but I feel like launching across multiple Availability Zones could help with performance, so maybe option D is worth considering?

I remember studying about EFA and its benefits for HPC workloads, so I think option C is definitely a good choice.
