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

1. A data engineer observes that an upstream streaming source sends duplicate records, where duplicates share the same key and have at most a 30-minute difference in event_timestamp. The engineer adds:
dropDuplicatesWithinWatermark("event_timestamp", "30 minutes")
What is the result?

A) It removes all duplicates regardless of when they arrive
B) It accepts watermarks in seconds and the code results in an error
C) It removes duplicates that arrive within the 30-minute window specified by the watermark
D) It is not able to handle deduplication in this scenario

2. 16 of 55.
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) Only actions trigger the execution of the transformation pipeline.
B) The Spark engine optimizes the execution plan during the transformations, causing delays.
C) Transformations are executed immediately to build the lineage graph.
D) Transformations are evaluated lazily.
E) The Spark engine requires manual intervention to start executing transformations.

3. Given:
python
CopyEdit
spark.sparkContext.setLogLevel("<LOG_LEVEL>")
Which set contains the suitable configuration settings for Spark driver LOG_LEVELs?

A) ALL, DEBUG, FAIL, INFO
B) FATAL, NONE, INFO, DEBUG
C) WARN, NONE, ERROR, FATAL
D) ERROR, WARN, TRACE, OFF

4. A data scientist is analyzing a large dataset and has written a PySpark script that includes several transformations and actions on a DataFrame. The script ends with a collect() action to retrieve the results.
How does Apache Spark™'s execution hierarchy process the operations when the data scientist runs this script?

A) The script is first divided into multiple applications, then each application is split into jobs, stages, and finally tasks.
B) The collect() action triggers a job, which is divided into stages at shuffle boundaries, and each stage is split into tasks that operate on individual data partitions.
C) Spark creates a single task for each transformation and action in the script, and these tasks are grouped into stages and jobs based on their dependencies.
D) The entire script is treated as a single job, which is then divided into multiple stages, and each stage is further divided into tasks based on data partitions.

5. 3 of 55. A data engineer observes that the upstream streaming source feeds the event table frequently and sends duplicate records. Upon analyzing the current production table, the data engineer found that the time difference in the event_timestamp column of the duplicate records is, at most, 30 minutes.
To remove the duplicates, the engineer adds the code:
df = df.withWatermark("event_timestamp", "30 minutes")
What is the result?

A) It is not able to handle deduplication in this scenario.
B) It removes all duplicates regardless of when they arrive.
C) It accepts watermarks in seconds and the code results in an error.
D) It removes duplicates that arrive within the 30-minute window specified by the watermark.
