Question

A company has Amazon EC2 instances that run nightly batch jobs to process data. The EC2 instances run in an Auto Scaling group that uses On-Demand billing. If a job fails on one instance, another instance will reprocess the job. The batch jobs run between 12:00 AM and 06:00 AM local time every day. Which solution will provide EC2 instances to meet these requirements MOST cost-effectively?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Create a new launch template for the Auto Scaling group. Set the instances to Spot Instances. Set a policy to scale out based on CPU usage. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Spot Instances use spare capacity at a large discount, ideal for fault-tolerant or interruptible workloads. This option delivers the requirement at the lowest cost.
