Q18 — AWS DEA-C01 Ch.1

Question 18 of 100 | ← Chapter 1

A company maintains multiple extract, transform, and load (ETL) workflows that ingest data from the company's operational databases into an Amazon S3 based data lake. The ETL workflows use AWS Glue and Amazon EMR to process data. The company wants to improve the existing architecture to provide automated orchestration and to require minimal manual effort. Which solution will meet these requirements with the LEAST operational overhead?

• A. AWS Glue workflows
• B. AWS Step Functions tasks ✓
• C. AWS Lambda functions
• D. Amazon Managed Workflows for Apache Airflow (Amazon MWAA) workflows

Correct Answer: B. AWS Step Functions tasks

Explanation

AWSStepFunctions任务能够以直观的方式协调和编排多个不同的AWS服务，实现工作流的自动化，并且操作开销相对较小。对于该公司希望改进现有架构以提供自动化编排并需要最少手动操作的需求，AWSStepFunctions任务是一个合适的选择。相比之下，AWSGlueWorkflows主要侧重于数据的提取、转换和加载操作；AWSLambdafunctions通常用于执行特定的短时间运行的任务；AmazonManagedWorkflowsforApacheAirflow(AmazonMWAA)Workflows虽然也能进行工作流管理，但可能在某些情况下操作复杂度和开销较大。因此，选项B是符合要求的答案。
