Databricks Certified Associate Developer for Apache Spark 3.5 - Python Sample Questions:

1. 32 of 55.
A developer is creating a Spark application that performs multiple DataFrame transformations and actions. The developer wants to maintain optimal performance by properly managing the SparkSession.
How should the developer handle the SparkSession throughout the application?

A) Create a new SparkSession instance before each transformation.
B) Stop and restart the SparkSession after each action.
C) Use a single SparkSession instance for the entire application.
D) Avoid using a SparkSession and rely on SparkContext only.

2. A data engineer is working on the DataFrame:

(Referring to the table image: it has columns Id, Name, count, and timestamp.) Which code fragment should the engineer use to extract the unique values in the Name column into an alphabetically ordered list?

A) df.select("Name").distinct().orderBy(df["Name"])
B) df.select("Name").distinct().orderBy(df["Name"].desc())
C) df.select("Name").orderBy(df["Name"].asc())
D) df.select("Name").distinct()

3. What is the behavior for function date_sub(start, days) if a negative value is passed into the days parameter?

A) The number of days specified will be removed from the start date
B) An error message of an invalid parameter will be returned
C) The number of days specified will be added to the start date
D) The same start date will be returned

4. A data engineer is reviewing a Spark application that applies several transformations to a DataFrame but notices that the job does not start executing immediately.
Which two characteristics of Apache Spark's execution model explain this behavior?
Choose 2 answers:

A) Transformations are executed immediately to build the lineage graph.
B) Transformations are evaluated lazily.
C) The Spark engine requires manual intervention to start executing transformations.
D) Only actions trigger the execution of the transformation pipeline.
E) The Spark engine optimizes the execution plan during the transformations, causing delays.

5. A data scientist is working on a project that requires processing large amounts of structured data, performing SQL queries, and applying machine learning algorithms. The data scientist is considering using Apache Spark for this task.
Which combination of Apache Spark modules should the data scientist use in this scenario?
Options:

A) Spark SQL, Pandas API on Spark, and Structured Streaming
B) Spark DataFrames, Structured Streaming, and GraphX
C) Spark Streaming, GraphX, and Pandas API on Spark
D) Spark DataFrames, Spark SQL, and MLlib
