A solutions architect needs to review the design of an Amazon EMR cluster that is using the EMR File System (EMRFS). The cluster performs tasks that are critical to business needs. The cluster is running Amazon EC2 On-Demand Instances at all times for all task, primary, and core nodes. The EMR tasks run each morning, starting at 1:00 AM. and take 6 hours to nish running. The amount of time to complete the processing is not a priority because the data is not referenced until late in the day. The solutions architect must review the architecture and suggest a solution to minimize the compute costs. Which solution should the solutions architect recommend to meet these requirements?

The solutions architect must review the architecture and suggest a solution to minimize the compute costs.
Which solution should the solutions architect recommend to meet these requirements?

A. Launch all task, primary, and core nodes on Spot Instances in an instance eet. Terminate the cluster, including all instances, when the processing is completed.

B. Launch the primary and core nodes on On-Demand Instances. Launch the task nodes on Spot Instances in an instance eet. Terminate the cluster, including all instances, when the processing is completed. Purchase Compute Savings Plans to cover the On-Demand Instance usage.

C. Continue to launch all nodes on On-Demand Instances. Terminate the cluster, including all instances, when the processing is completed.
Purchase Compute Savings Plans to cover the On-Demand Instance usage.

D. Launch the primary and core nodes on On-Demand Instances. Launch the task nodes on Spot Instances in an instance eet. Terminate only the task node instances when the processing is completed. Purchase Compute Savings Plans to cover the On-Demand Instance usage.

Correct Answer: D
