AWS Certified SysOps Administrator – Associate — Question 172

A company plans to migrate several of its high performance computing (HPC) virtual machines (VMs) to Amazon EC2 instances on AWS. A SysOps administrator must identify a placement group for this deployment. The strategy must minimize network latency and must maximize network throughput between the HPC VMs.

Which strategy should the SysOps administrator choose to meet these requirements?

Answer options

• 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.

Correct answer: A

Explanation

The correct answer is A because a cluster placement group is designed to provide low latency and high throughput by placing instances in close proximity within a single Availability Zone. Options B and C use partition placement groups, which are better for workloads that require high availability but do not optimize for latency and throughput as effectively as a cluster group. Option D involves a spread placement group, which is designed for high availability across different zones but again does not maximize performance for HPC workloads.
