Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 358 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 358
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances. The fleet consists of a primary node and eight worker nodes. The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes, and sending an aggregate response back to a client. Worker nodes communicate with each other to replicate data partitions.

The company requires the lowest possible networking latency to achieve maximum performance.

Which solution will meet these requirements?

  • A. Launch memory optimized EC2 instances in a partition placement group.
  • B. Launch compute optimized EC2 instances in a partition placement group.
  • C. Launch memory optimized EC2 instances in a cluster placement group.
  • D. Launch compute optimized EC2 instances in a spread placement group.

C is right Cluster placement groups (CPGs) are designed to place related resources into the same Availability Zone (AZ), which reduces latency and improves network performance. Since this is a distributed in-memory database with multiple nodes that need to communicate quickly, using a CPG for memory-optimized EC2 instances would be an ideal solution. By launching memory-optimized EC2 instances in a cluster placement group: You can reduce latency by minimizing network hops between nodes You can improve communication efficiency between nodes
