Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 456 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 456
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company needs to run large batch-processing jobs on data that is stored in an Amazon S3 bucket. The jobs perform simulations. The results of the jobs are not time sensitive, and the process can withstand interruptions.

Each job must process 15-20 GB of data when the data is stored in the S3 bucket. The company will store the output from the jobs in a different Amazon S3 bucket for further analysis.

Which solution will meet these requirements MOST cost-effectively?

  • A. Create a serverless data pipeline. Use AWS Step Functions for orchestration. Use AWS Lambda functions with provisioned capacity to process the data.
  • B. Create an AWS Batch compute environment that includes Amazon EC2 Spot Instances. Specify the SPOT_CAPACITY_OPTIMIZED allocation strategy.
  • C. Create an AWS Batch compute environment that includes Amazon EC2 On-Demand Instances and Spot Instances. Specify the SPOT_CAPACITY_OPTIMIZED allocation strategy for the Spot Instances.
  • D. Use Amazon Elastic Kubernetes Service (Amazon EKS) to run the processing jobs. Use managed node groups that contain a combination of Amazon EC2 On-Demand Instances and Spot Instances.

Option B utilizes AWS Batch with EC2 Spot Instances and the SPOT_CAPACITY_OPTIMIZED allocation strategy. This approach takes advantage of the Spot Instance pricing model, which provides a significant discount compared to On-Demand pricing. By using this configuration, the company can process large batch jobs at a lower cost while still meeting the specified requirements.

Selected Answer: B
B C is wrong due to the following AWS Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Instance types that are less likely to be interrupted are preferred. This allocation strategy is only available for Spot Instance compute resources. https://docs.aws.amazon.com/batch/latest/userguide/allocation-strategies.html
