Exam SOA-C03 Topic 4 Question 6 Discussion

Actual exam question for Amazon's SOA-C03 exam
Question #: 6
Topic #: 4
A company plans to migrate several of its high-performance computing (HPC) virtual machines to Amazon EC2. The deployment must minimize network latency and maximize network throughput between the instances.
Which placement group strategy should the CloudOps engineer choose?

Suggested Answer: A Vote an answer

Comprehensive Explanation (250-350 words):
Cluster placement groups are specifically designed for workloads that require extremely low latency and high network throughput, such as HPC applications. Instances are placed physically close together within the same Availability Zone, enabling high-bandwidth, low-latency networking.
Partition placement groups are optimized for fault isolation, not network performance. Spread placement groups prioritize availability by distributing instances across distinct hardware, which increases latency.
Because the requirement is performance rather than fault isolation or high availability, a cluster placement group is the optimal choice.
