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

1. A data engineer is running a batch processing job on a Spark cluster with the following configuration:
10 worker nodes
16 CPU cores per worker node
64 GB RAM per node
The data engineer wants to allocate four executors per node, each executor using four cores.
What is the total number of CPU cores used by the application?

A) 40
B) 80
C) 160
D) 64

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

3. A data engineer needs to write a DataFrame df to a Parquet file, partitioned by the column country, and overwrite any existing data at the destination path.
Which code should the data engineer use to accomplish this task in Apache Spark?

A) df.write.mode("overwrite").partitionBy("country").parquet("/data/output")
B) df.write.mode("append").partitionBy("country").parquet("/data/output")
C) df.write.partitionBy("country").parquet("/data/output")
D) df.write.mode("overwrite").parquet("/data/output")

4. 18 of 55.
An engineer has two DataFrames - df1 (small) and df2 (large). To optimize the join, the engineer uses a broadcast join:
from pyspark.sql.functions import broadcast
df_result = df2.join(broadcast(df1), on="id", how="inner")
What is the purpose of using broadcast() in this scenario?

A) It increases the partition size for df1 and df2.
B) It ensures that the join happens only when the id values are identical.
C) It reduces the number of shuffle operations by replicating the smaller DataFrame to all nodes.
D) It filters the id values before performing the join.

5. A Spark developer is building an app to monitor task performance. They need to track the maximum task processing time per worker node and consolidate it on the driver for analysis.
Which technique should be used?

A) Configure the Spark UI to automatically collect maximum times
B) Use an RDD action like reduce() to compute the maximum time
C) Use an accumulator to record the maximum time on the driver
D) Broadcast a variable to share the maximum time among workers
