NEW QUESTION # 22
A developer initializes a SparkSession:

spark = SparkSession.builder
.appName("Analytics Application")
.getOrCreate()
Which statement describes thesparkSparkSession?

  • A. If a SparkSession already exists, this code will return the existing session instead of creating a new one.
  • B. A SparkSession is unique for eachappName, and callinggetOrCreate()with the same name will return an existing SparkSession once it has been created.
  • C. ThegetOrCreate()method explicitly destroys any existing SparkSession and creates a new one.
  • D. A new SparkSession is created every time thegetOrCreate()method is invoked.

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
According to the PySpark API documentation:
"getOrCreate(): Gets an existing SparkSession or, if there is no existing one, creates a new one based on the options set in this builder." This means Spark maintains a global singleton session within a JVM process. Repeated calls togetOrCreate() return the same session, unless explicitly stopped.
Option A is incorrect: the method does not destroy any session.
Option B incorrectly ties uniqueness toappName, which does not influence session reusability.
Option D is incorrect: it contradicts the fundamental behavior ofgetOrCreate().

NEW QUESTION # 23
Given the following code snippet inmy_spark_app.py:

What is the role of the driver node?

  • A. The driver node stores the final result after computations are completed by worker nodes
  • B. The driver node holds the DataFrame data and performs all computations locally
  • C. The driver node only provides the user interface for monitoring the application
  • D. The driver node orchestrates the execution by transforming actions into tasks and distributing them to worker nodes

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In the Spark architecture, the driver node is responsible for orchestrating the execution of a Spark application.
It converts user-defined transformations and actions into a logical plan, optimizes it into a physical plan, and then splits the plan into tasks that are distributed to the executor nodes.
As per Databricks and Spark documentation:
"The driver node is responsible for maintaining information about the Spark application, responding to a user's program or input, and analyzing, distributing, and scheduling work across the executors." This means:
Option A is correct because the driver schedules and coordinates the job execution.
Option B is incorrect because the driver does more than just UI monitoring.
Option C is incorrect since data and computations are distributed across executor nodes.
Option D is incorrect; results are returned to the driver but not stored long-term by it.

NEW QUESTION # 24
Given a CSV file with the content:

And the following code:
from pyspark.sql.types import *
schema = StructType([
StructField("name", StringType()),
StructField("age", IntegerType())
])
spark.read.schema(schema).csv(path).collect()
What is the resulting output?

  • A. [Row(name='alladin', age=20)]
  • B. [Row(name='bambi'), Row(name='alladin', age=20)]
  • C. [Row(name='bambi', age=None), Row(name='alladin', age=20)]
  • D. The code throws an error due to a schema mismatch.

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In Spark, when a CSV row does not match the provided schema, Spark does not raise an error by default.
Instead, it returnsnullfor fields that cannot be parsed correctly.
In the first row,"hello"cannot be cast to Integer for theagefield # Spark setsage=None In the second row,"20"is a valid integer #age=20 So the output will be:
[Row(name='bambi', age=None), Row(name='alladin', age=20)]
Final Answer: C


NEW QUESTION # 25
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.option("inferSchema", "true").parquet("/path/events/data/")
  • C. df = spark.read.parquet("/path/events/data/*")
  • D. df = spark.read.parquet("/path/events/data/")

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To read all files recursively within a nested directory structure, Spark requires therecursiveFileLookupoption to be explicitly enabled. According to Databricks official documentation, when dealing with deeply nested Parquet files in a directory tree (as shown in this example), you should set:
df = spark.read.option("recursiveFileLookup", "true").parquet("/path/events/data/") This ensures that Spark searches through all subdirectories under/path/events/data/and reads any Parquet files it finds, regardless of the folder depth.
Option A is incorrect because while it includes an option,inferSchemais irrelevant here and does not enable recursive file reading.
Option C is incorrect because wildcards may not reliably match deep nested structures beyond one directory level.
Option D is incorrect because it will only read files directly within/path/events/data/and not subdirectories like
/2023/01/01.
Databricks documentation reference:
"To read files recursively from nested folders, set therecursiveFileLookupoption to true. This is useful when data is organized in hierarchical folder structures" - Databricks documentation on Parquet files ingestion and options.


NEW QUESTION # 26
A data engineer is working on a real-time analytics pipeline using Apache Spark Structured Streaming. The engineer wants to process incoming data and ensure that triggers control when the query is executed. The system needs to process data in micro-batches with a fixed interval of 5 seconds.
Which code snippet the data engineer could use to fulfil this requirement?
A)

B)

C)

D)

Options:

  • A. Uses trigger(continuous='5 seconds') - continuous processing mode.
  • B. Uses trigger() - default micro-batch trigger without interval.
  • C. Uses trigger(processingTime='5 seconds') - correct micro-batch trigger with interval.
  • D. Uses trigger(processingTime=5000) - invalid, as processingTime expects a string.

Answer: C

Explanation:
To define a micro-batch interval, the correct syntax is:
query = df.writeStream
outputMode("append")
trigger(processingTime='5 seconds')
start()
This schedules the query to execute every 5 seconds.
Continuous mode (used in Option A) is experimental and has limited sink support.
Option D is incorrect because processingTime must be a string (not an integer).
Option B triggers as fast as possible without interval control.
