Amazon Web Services AWS Certified Solutions Architect - Associate (SAA-C03) SAA-C03 Question # 5 Topic 1 Discussion

SAA-C03 Exam Topic 1 Question 5 Discussion:
Question #: 5
Topic #: 1

A solutions architect needs to design a solution for a high performance computing (HPC) workload. The solution must include multiple Amazon EC2 instances. Each EC2 instance requires 10 Gbps of bandwidth individually for single-flow traffic. The EC2 instances require an aggregate throughput of 100 Gbps of bandwidth across all EC2 instances. Communication between the EC2 instances must have low latency.

Which solution will meet these requirements?
A.

Place the EC2 instances in a single subnet of a VPC. Configure a cluster placement group. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

B.

Place the EC2 instances in multiple subnets in a single VPC. Configure a spread placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.

C.

Place the EC2 instances in multiple VPCs. Use AWS Transit Gateway to route traffic between the VPCs. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

D.

Place the EC2 instances in multiple subnets across multiple Availability Zones. Configure a cluster placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.
