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

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

1. A Spark application suffers from too many small tasks due to excessive partitioning. How can this be fixed without a full shuffle?
Options:

A) Use the distinct() transformation to combine similar partitions
B) Use the repartition() transformation with a lower number of partitions
C) Use the coalesce() transformation with a lower number of partitions
D) Use the sortBy() transformation to reorganize the data

2. A Spark application developer wants to identify which operations cause shuffling, leading to a new stage in the Spark execution plan.
Which operation results in a shuffle and a new stage?

A) DataFrame.withColumn()
B) DataFrame.select()
C) DataFrame.groupBy().agg()
D) DataFrame.filter()

3. A data engineer is streaming data from Kafka and requires:
Minimal latency
Exactly-once processing guarantees
Which trigger mode should be used?

A) .trigger(continuous='1 second')
B) .trigger(processingTime='1 second')
C) .trigger(continuous=True)
D) .trigger(availableNow=True)

4. A data scientist is working on a large dataset in Apache Spark using PySpark. The data scientist has a DataFrame df with columns user_id, product_id, and purchase_amount and needs to perform some operations on this data efficiently.
Which sequence of operations results in transformations that require a shuffle followed by transformations that do not?

A) df.withColumn("purchase_date", current_date()).where("total_purchase > 50")
B) df.filter(df.purchase_amount > 100).groupBy("user_id").sum("purchase_amount")
C) df.withColumn("discount", df.purchase_amount * 0.1).select("discount")
D) df.groupBy("user_id").agg(sum("purchase_amount").alias("total_purchase")).repartition(10)

5. An engineer wants to join two DataFrames df1 and df2 on the respective employee_id and emp_id columns:
df1: employee_id INT, name STRING
df2: emp_id INT, department STRING
The engineer uses:
result = df1.join(df2, df1.employee_id == df2.emp_id, how='inner')
What is the behaviour of the code snippet?

A) The code fails to execute because PySpark does not support joining DataFrames with a different structure
B) The code works as expected because the join condition explicitly matches employee_id from df1 with emp_id from df2
C) The code fails to execute because it must use on='employee_id' to specify the join column explicitly
D) The code fails to execute because the column names employee_id and emp_id do not match automatically
