Question
A company is deploying an application that processes large quantities of data in parallel. The company plans to use Amazon EC2 instances for the workload. The network architecture must be configurable to provide the lowest possible latency between nodes. Which combination of network solutions will meet these requirements? (Choose two.)
Options
- ADistribute the EC2 instances across multiple Availability Zones.
- BAttach an Elastic Fabric Adapter (EFA) to each EC2 instance.
- CPlace the EC2 instances in a single Availability Zone.
- DUse Amazon Elastic Block Store (Amazon EBS) optimized instance types.
- ERun the EC2 instances in a cluster placement group.

Explanation
Elastic Fabric Adapter (EFA) provides low-latency, high-throughput networking for tightly coupled, parallel workloads. Running EC2 instances in a cluster placement group ensures the instances are physically close within a single Availability Zone, minimizing network latency between nodes.
