Topic 1 Question 235
A company has built a high performance computing (HPC) cluster in AWS for 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?

3 つ選択
- Ensure the HPC cluster is launched within a single Availability Zone.
- Launch the EC2 instances and attach elastic network interfaces in multiples of four.
- Select EC2 instance types with an Elastic Fabric Adapter (EFA) enabled.
- Ensure the cluster is launched across multiple Availability Zones.
- Replace Amazon EFS with multiple Amazon EBS volumes in a RAID array.
- Replace Amazon EFS with Amazon FSx for Lustre.

- 正解だと思う選択肢: ACF
  A. Ensure the HPC cluster is launched within a single Availability Zone: This choice ensures that the EC2 instances in the cluster have low network latency and high bandwidth, as they are located within the same data center. C. Select EC2 instance types with an Elastic Fabric Adapter (EFA) enabled: EFA is a network interface that provides low-latency, high-bandwidth communication between EC2 instances. By selecting instance types with EFA enabled, the cluster can benefit from improved inter-instance communication. F. Replace Amazon EFS with Amazon FSx for Lustre: Amazon FSx for Lustre is a high-performance file system optimized for HPC workloads. By using FSx for Lustre instead of Amazon EFS, the cluster can achieve better performance for the large number of shared files generated by the workload.
  
  And what about a cluster placement group?

- 正解だと思う選択肢: CDF
  CDF are correct
  
  C - EFA provides low-latency and high-bandwidth communication between EC2 instances. It can optimize the network performance of the HPC cluster. D - Launching the HPC cluster across multiple Availability Zones allows you to distribute the workload and resources, reducing the chances of a single point of failure and increasing overall performance. F - FSx for Lustre is a high-performance file system optimized for HPC workloads.
