A company performs advanced statistical analysis by using custom software.

When you have EC2 instances requiring low-latency, high-throughput communication, the best placement strategy is to use a cluster placement group.

From the AWS EC2 Placement Group Guide:

A cluster placement group is a logical grouping of instances within a single AZ.

This strategy enables workloads to achieve low-latency network performance needed for tightly coupled node-to-node communication.

❌ Why the other options are incorrect:

B: Elastic IPs are used for static public IP addressing — they do not affect intra-cluster latency.

C: Jumbo frames require support from all hardware/network layers and are not guaranteed to lower latency.

D: Spread placement groups distribute instances across different hardware, which increases latency.
