Answer: Deploy the instances in a cluster placement group in one Availability Zone.
A cluster placement group is a logical grouping of instances within a single Availability Zone. Cluster placement groups are recommended for applications that benefit from low network latency, high network throughput, or both, such as high performance computing (HPC) applications. Partition and spread placement groups are designed to reduce the likelihood of correlated hardware failures, rather than minimizing latency.

The strategy must minimize network latency and must maximize network throughput between the HPC VMs. Which strategy should the CloudOps engineer choose to meet these requirements?
A
Deploy the instances in a cluster placement group in one Availability Zone.
B
Deploy the instances in a partition placement group in two Availability Zones.
C
Deploy the instances in a partition placement group in one Availability Zone.
D
Deploy the instances in a spread placement group in two Availability Zones.
