Sample Questions

Question #263 / 529

A solutions architect is evaluating the architecture of an Amazon EMR cluster utilizing EMRFS. The cluster handles essential business operations and currently runs on Amazon EC2 On-Demand Instances for all node types (primary, core, and task).

The goal is to reduce compute costs without compromising reliability.

Which solution should the solutions architect implement to meet these requirements?

A

Deploy all nodes on Spot Instances within an instance fleet. Shut down the entire cluster post-processing.

B

Use On-Demand Instances for primary and core nodes. Launch task nodes on Spot Instances in an instance fleet. Terminate the entire cluster after processing. Purchase Compute Savings Plans for On-Demand usage.

C

Keep all nodes on On-Demand Instances. Terminate the cluster post-processing. Buy Compute Savings Plans for On-Demand usage.

D

Run primary and core nodes on On-Demand Instances. Utilize Spot Instances for task nodes in an instance fleet. Only terminate task nodes post-processing. Purchase Compute Savings Plans for On-Demand usage.
