AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 652

Question

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?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Configure a transient cluster that runs the primary node and core nodes on On-Demand Instances and the task nodes on Spot Instances. Spot Instances use spare capacity at a large discount, ideal for fault-tolerant or interruptible workloads. AWS Config tracks resource configuration changes and evaluates compliance. This option delivers the requirement at the lowest cost.
