A is correct
A indeed correct
Option A is the most suitable solution for the high-performance computing workload: Cluster Placement Group: A cluster placement group ensures that EC2 instances are placed close together within the same Availability Zone to minimize network latency and provide high-bandwidth, low-latency communication between instances. This is crucial for an HPC workload where low-latency communication is essential. Single Subnet of a VPC: Placing nodes in a single subnet of a VPC ensures that the EC2 instances are closely located within the same subnet, further reducing network latency. Elastic Fabric Adapter (EFA): EFA is a network interface designed specifically for HPC workloads that require low-latency and high-bandwidth communication. Using EFA drivers on EC2 instances ensures optimal performance for communication between instances.
