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?

Launch memory optimized EC2 instances in a partition placement group.

Launch compute optimized EC2 instances in a partition placement group.

Launch memory optimized EC2 instances in a cluster placement group.

Launch compute optimized EC2 instances in a spread placement group.

Explanations:

While memory-optimized instances help with data storage and processing, a partition placement group does not provide the lowest possible networking latency for inter-instance communication.

Compute-optimized instances could enhance processing power, but a partition placement group does not guarantee the lowest latency required for this distributed in-memory database setup.

Memory-optimized instances in a cluster placement group offer the lowest possible networking latency, ideal for high-performance, low-latency requirements across the cluster.

Spread placement groups prioritize instance isolation across hardware rather than reducing latency, which does not meet the requirement for minimal networking latency.

    If I’m correct, the answer is:
    Launch memory optimized EC2 instances in a cluster placement group.
