Which solution will meet these requirements?
Launch five new EC2 instances into a cluster placement group. Ensure that the EC2 instance type supports enhanced networking.
Launch five new EC2 instances into an Auto Scaling group in the same Availability Zone. Attach an extra elastic network interface to each EC2 instance.
Launch five new EC2 instances into a partition placement group. Ensure that the EC2 instance type supports enhanced networking.
Launch five new EC2 instances into a spread placement group. Attach an extra elastic network interface to each EC2 instance.
Explanations:
A cluster placement group ensures low-latency, high-throughput network performance between EC2 instances. This is ideal for applications that need tight inter-instance communication. Enhanced networking further improves performance.
An Auto Scaling group and attaching extra elastic network interfaces does not ensure high-throughput, low-latency communication between instances. Auto Scaling is focused on scaling, not on network performance.
A partition placement group is designed for distributing instances across distinct physical hardware to reduce correlated failures, not for achieving high-throughput, low-latency network performance.
A spread placement group is intended to spread instances across multiple hardware to reduce the risk of correlated failures, but does not provide the network performance needed for low-latency, high-throughput communication between instances.
I scheme that the answer is:
Launch five new EC2 instances into a cluster placement group. Ensure that the EC2 instance type supports enhanced networking.
