Q4 — AWS DEA-C01 Ch.1

Question 4 of 100 | ← Chapter 1

A company created an extract, transform, and load (ETL) data pipeline in AWS Glue. A data engineer must crawl a table that is in Microsoft SQL Server. The data engineer needs to extract, transform, and load the output of the crawl to an Amazon S3 bucket. The data engineer also Must orchestrate the data pipeline. Which AWS service or feature will meet these requirements MOST cost-effectively?

Correct Answer: B. AWS Glue workflows

Explanation

在这个场景中,数据工程师需要在AWSGlue中创建一个ETL数据管道,用于从MicrosoftSQLServer中提取数据,并将其转换和加载到AmazonS3桶中。同时,还需要对数据管道进行编排。考虑到AWSGlueworkflows提供了内置的ETL功能,可以直接与AWSGlue集成,并且支持数据管道的编排,因此它是最符合成本效益的选择。AWSStepFunctions虽然可以用于编排,但它本身不提供ETL功能。AWSGlueStudio提供了一个可视化界面,但可能不如workflows成本效益高。AmazonMWAA是基于ApacheAirflow的工作流服务,虽然功能强大,但可能涉及额外的成本和复杂性。因此,选项B是最合适的答案。
