The correct answer is C. Place the EC2 instances in an Auto Scaling group within a single subnet. D. Launch the EC2 instances into a cluster placement group. Cluster - packs instances close together inside an Availability Zone.

Explanation
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 high-performance computing (HPC) applications. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html
