Databricks Certified Data Engineer Associate — Question 122

Which of the following benefits is provided by the array functions from Spark SQL?

Answer options

• A. An ability to work with data in a variety of types at once
• B. An ability to work with data within certain partitions and windows
• C. An ability to work with time-related data in specified intervals
• D. An ability to work with complex, nested data ingested from JSON files

Correct answer: D

Explanation

The correct answer is D because Spark SQL's array functions are specifically designed to manage complex structures, including nested data from JSON. Options A, B, and C describe capabilities that are not the primary focus of the array functions, which are more centered on complex data rather than types, partitions, or time intervals.
