Question 22 of 100 | ← Chapter 10

Q622. 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 prevent groups of nodes from sharing the same underlying hardware.Which networking solution meets these requirements?

Correct Answer: A. Run the EC2 instances in a spread placement group

Explanation

Apologies for the confusion in the previous response. The correct answer to the question is:A. Run the EC2 instances in a spread placement group.To prevent groups of nodes from sharing the same underlying hardware when deploying an application that processes large quantities of data in parallel using Amazon EC2 instances, you can use spread placement groups. Spread placement groups ensure that instances are placed on distinct underlying hardware to minimize the risk of simultaneous failures.By running the EC2 instances in a spread placement group, you can maximize the isolation between instances and reduce the likelihood of them sharing the same hardware. This helps to enhance the fault tolerance and availability of your application.Option B, grouping the EC2 instances in separate accounts, does not directly address the requirement of preventing groups of nodes from sharing the same underlying hardware. Option C, configuring the EC2 instances with dedicated tenancy, ensures that instances run on dedicated hardware but does not provide isolation within the group of instances. Option D, configuring the EC2 instances with shared tenancy, allows instances to share the same underlying hardware, which goes against the requirement of preventing sharing. Therefore, the most appropriate networking solution to prevent groups of nodes from sharing the same underlying hardware in this scenario is to run the EC2 instances in a spread placement group (option A).
