A company has a new application that needs to run on five Amazon EC2 instances in a single AWS Region. The application requires high-throughput, low-latency network connections between all of the EC2 instances where the application will run. There is no requirement for the application to be fault tolerant.
Which solution will meet these requirements?
A . Launch five new EC2 instances into a cluster placement group. Ensure that the EC2 instance type supports enhanced networking.
B. 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.
C. Launch five new EC2 instances into a partition placement group. Ensure that the EC2 instance type supports enhanced networking.
D. Launch five new EC2 instances into a spread placement group. Attach an extra elastic network interface to each EC2 instance.
Answer: A
Explanation:
When you launch EC2 instances in a cluster they benefit from performance and low latency. No redundancy though as per the question https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html.
