Databricks Associate-Developer-Apache-Spark-3.5 Exam Syllabus Topics:

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

Question 1

An MLOps engineer is building a Pandas UDF that applies a language model that translates English strings into Spanish. The initial code is loading the model on every call to the UDF, which is hurting the performance of the data pipeline.
The initial code is:

def in_spanish_inner(df: pd.Series) -> pd.Series:
model = get_translation_model(target_lang='es')
return df.apply(model)
in_spanish = sf.pandas_udf(in_spanish_inner, StringType())
How can the MLOps engineer change this code to reduce how many times the language model is loaded?

A. Convert the Pandas UDF to a PySpark UDF
B. Convert the Pandas UDF from a Series → Series UDF to an Iterator[Series] → Iterator[Series] UDF
C. Run the in_spanish_inner() function in a mapInPandas() function call
D. Convert the Pandas UDF from a Series → Series UDF to a Series → Scalar UDF

Question 2

A data engineer writes the following code to join two DataFrames df1 and df2:
df1 = spark.read.csv("sales_data.csv") # ~10 GB
df2 = spark.read.csv("product_data.csv") # ~8 MB
result = df1.join(df2, df1.product_id == df2.product_id)

Which join strategy will Spark use?

A. Shuffle join because no broadcast hints were provided
B. Broadcast join, as df2 is smaller than the default broadcast threshold
C. Shuffle join, because AQE is not enabled, and Spark uses a static query plan
D. Shuffle join, as the size difference between df1 and df2 is too large for a broadcast join to work efficiently

Question 3

A data engineer is asked to build an ingestion pipeline for a set of Parquet files delivered by an upstream team on a nightly basis. The data is stored in a directory structure with a base path of "/path/events/data". The upstream team drops daily data into the underlying subdirectories following the convention year/month/day.
A few examples of the directory structure are:

Which of the following code snippets will read all the data within the directory structure?

A. df = spark.read.option("recursiveFileLookup", "true").parquet("/path/events/data/")
B. df = spark.read.parquet("/path/events/data/")
C. df = spark.read.parquet("/path/events/data/*")
D. df = spark.read.option("inferSchema", "true").parquet("/path/events/data/")

Question 4

A data engineer is building a Structured Streaming pipeline and wants the pipeline to recover from failures or intentional shutdowns by continuing where the pipeline left off.
How can this be achieved?

A. By configuring the option checkpointLocation during writeStream
B. By configuring the option recoveryLocation during writeStream
C. By configuring the option recoveryLocation during the SparkSession initialization
D. By configuring the option checkpointLocation during readStream

Question 5

48 of 55.
A data engineer needs to join multiple DataFrames and has written the following code:
from pyspark.sql.functions import broadcast
data1 = [(1, "A"), (2, "B")]
data2 = [(1, "X"), (2, "Y")]
data3 = [(1, "M"), (2, "N")]
df1 = spark.createDataFrame(data1, ["id", "val1"])
df2 = spark.createDataFrame(data2, ["id", "val2"])
df3 = spark.createDataFrame(data3, ["id", "val3"])
df_joined = df1.join(broadcast(df2), "id", "inner") \
.join(broadcast(df3), "id", "inner")
What will be the output of this code?

A. The code will fail because only one broadcast join can be performed at a time.
B. The code will result in an error because broadcast() must be called before the joins, not inline.
C. The code will work correctly and perform two broadcast joins simultaneously to join df1 with df2, and then the result with df3.
D. The code will fail because the second join condition (df2.id == df3.id) is incorrect.
