Which combination of network solutions will meet these requirements?
(Choose two.)
Enable and configure enhanced networking on each EC2 instance.
Group the EC2 instances in separate accounts.
Run the EC2 instances in a cluster placement group.
Attach multiple elastic network interfaces to each EC2 instance.
Use Amazon Elastic Block Store (Amazon EBS) optimized instance types.
Explanations:
Enabling and configuring enhanced networking (e.g., using Elastic Network Adapter) reduces network latency and improves throughput.
Grouping EC2 instances in separate accounts adds complexity and doesn’t optimize network latency.
Running EC2 instances in a cluster placement group ensures instances are placed close to each other, minimizing latency.
Attaching multiple ENIs increases network interfaces but doesn’t directly reduce latency between instances.
EBS-optimized instances help with disk I/O performance, not network latency between EC2 instances.
As far as I can tell, the answer is:
Enable and configure enhanced networking on each EC2 instance.
