Q23 — AWS DEA-C01 Ch.1

Question 23 of 100 | ← Chapter 1

A data engineer needs to use AWS Step Functions to design an orchestration workflow. The workflow must parallel process a large collection of data files and apply a specific transformation to each file. Which Step Functions state should the data engineer use to meet these requirements?

• A. Parallel state
• B. Parallel state
• C. Choice state
• D. Map state ✓
• E. Wait state

Correct Answer: D. Map state

Explanation

这道题考查对AWSStepFunctions中不同状态功能的理解。在处理需并行处理大量数据文件并应用特定转换的需求时，Choicestate通常用于根据条件进行选择和分支，不符合要求。Waitstate用于等待，也不适用。Parallelstate可实现并行处理，但Mapstate更适合对大量数据文件进行并行处理和特定转换。所以答案选C。
