Topic 1 Question 652
A company has a large data workload that runs for 6 hours each day. The company cannot lose any data while the process is running. A solutions architect is designing an Amazon EMR cluster configuration to support this critical data workload.
Which solution will meet these requirements MOST cost-effectively?
Configure a long-running cluster that runs the primary node and core nodes on On-Demand Instances and the task nodes on Spot Instances.
Configure a transient cluster that runs the primary node and core nodes on On-Demand Instances and the task nodes on Spot Instances.
Configure a transient cluster that runs the primary node on an On-Demand Instance and the core nodes and task nodes on Spot Instances.
Configure a long-running cluster that runs the primary node on an On-Demand Instance, the core nodes on Spot Instances, and the task nodes on Spot Instances.

Relax man. take a break since you have made this far so far.

A transient cluster provides cost savings because it runs only during the computation time, and it provides scalability and flexibility in a cloud environment.
Option C (transient cluster with On-Demand primary node and Spot core and task nodes) exposes the core nodes to Spot Instance interruptions, which may not be acceptable for a workload that cannot lose any data.

Cannot loose data = ondemand primary + core nodes Save on costs = spot task nodes Runs for 6 hours = transient cluster
