Selected Answer: A
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

Selected Answer: A
A. Use a cluster placement group in a single Availability Zone. Explanation: Cluster Placement Group (Option A): A cluster placement group is a logical grouping of instances within a single Availability Zone. Instances in a cluster placement group have low-latency, high-throughput communication with other instances in the same group. This type of placement group is suitable for applications that benefit from low-latency network communication. It is important to note that instances in a cluster placement group should be within a single Availability Zone.
