Topic 1 Question 386
A company has a high performance computing (HPC) application that runs on Amazon EC2 instances. The application requires minimum latency and maximum network throughput between nodes.
How should a SysOps administrator deploy the EC2 instances to meet these requirements?
Use a cluster placement group in a single Availability Zone.
Use a cluster placement group across multiple Availability Zones.

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.

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.
