Question
A network engineer needs to design the architecture for a high performance computing (HPC) workload. Amazon EC2 instances will require 10 Gbps flows and an aggregate throughput of up to 100 Gbps across many instances with low-latency communication. Which architecture solution will optimize this workload?
Options
- APlace nodes in a single subnet of a VPC. Configure a cluster placement group. Ensure that the
- BPlace nodes in multiple subnets in a single VPC. Configure a spread placement group. Ensure
- CPlace nodes in multiple VPCs Use AWS Transit Gateway to route traffic between the VPCs.
- DPlace nodes in multiple subnets in multiple Availability Zones. Configure a cluster placement
