Databricks Certified Associate Developer for Apache Spark — Question 170

Which of the following code blocks prints the schema of DataFrame storesDF?

Answer options

• A. print(storesDF)
• B. storesDF.printSchema()
• C. print(storesDF.schema())
• D. storesDF.schema
• E. storesDF.schema()

Correct answer: B

Explanation

The correct option is B, as the method printSchema() is specifically designed to output the schema of a DataFrame in Spark. Option A just prints the DataFrame itself, while options C, D, and E do not execute the correct function to display the schema directly in the intended manner.
