Databricks Certified Associate Developer for Apache Spark 3.5 - Python Sample Questions (Q15-Q20):

NEW QUESTION # 15
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(processingTime='5 seconds') - correct micro-batch trigger with interval.
C. Uses trigger(processingTime=5000) - invalid, as processingTime expects a string.
D. Uses trigger() - default micro-batch trigger without interval.

Answer: B

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.
Reference:Spark Structured Streaming - Triggers

NEW QUESTION # 16
What is the difference betweendf.cache()anddf.persist()in Spark DataFrame?

A. persist()- Persists the DataFrame with the default storage level (MEMORY_AND_DISK_SER) andcache()- Can be used to set different storage levels to persist the contents of the DataFrame.
B. Both functions perform the same operation. Thepersist()function provides improved performance asits default storage level isDISK_ONLY.
C. Bothcache()andpersist()can be used to set the default storage level (MEMORY_AND_DISK_SER)
D. cache()- Persists the DataFrame with the default storage level (MEMORY_AND_DISK) andpersist()- Can be used to set different storage levels to persist the contents of the DataFrame

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
df.cache()is shorthand fordf.persist(StorageLevel.MEMORY_AND_DISK)
df.persist()allows specifying any storage level such asMEMORY_ONLY,DISK_ONLY, MEMORY_AND_DISK_SER, etc.
By default,persist()usesMEMORY_AND_DISK, unless specified otherwise.

NEW QUESTION # 17
A data scientist is working on a project that requires processing large amounts of structured data, performing SQL queries, and applying machine learning algorithms. The data scientist is considering using Apache Spark for this task.
Which combination of Apache Spark modules should the data scientist use in this scenario?
Options:

A. Spark Streaming, GraphX, and Pandas API on Spark
B. Spark DataFrames, Structured Streaming, and GraphX
C. Spark DataFrames, Spark SQL, and MLlib
D. Spark SQL, Pandas API on Spark, and Structured Streaming

Answer: C

Explanation:
Comprehensive Explanation:
To cover structured data processing, SQL querying, and machine learning in Apache Spark, the correct combination of components is:
Spark DataFrames: for structured data processing
Spark SQL: to execute SQL queries over structured data
MLlib: Spark's scalable machine learning library
This trio is designed for exactly this type of use case.
Why other options are incorrect:
A: GraphX is for graph processing - not needed here.
B: Pandas API on Spark is useful, but MLlib is essential for ML, which this option omits.
C: Spark Streaming is legacy; GraphX is irrelevant here.
Reference:Apache Spark Modules Overview

NEW QUESTION # 18
How can a Spark developer ensure optimal resource utilization when running Spark jobs in Local Mode for testing?
Options:

A. Use the spark.dynamicAllocation.enabled property to scale resources dynamically.
B. Increase the number of local threads based on the number of CPU cores.
C. Configure the application to run in cluster mode instead of local mode.
D. Set the spark.executor.memory property to a large value.

Answer: B

Explanation:
When running in local mode (e.g., local[4]), the number inside the brackets defines how many threads Spark will use.
Using local[*] ensures Spark uses all available CPU cores for parallelism.
Example:
spark-submit --masterlocal[*]
Dynamic allocation and executor memory apply to cluster-based deployments, not local mode.
Reference:Spark Master URLs

NEW QUESTION # 19
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=True)
B. .trigger(processingTime='1 second')
C. .trigger(continuous='1 second')
D. .trigger(availableNow=True)

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
Exactly-once guarantees in Spark Structured Streaming require micro-batch mode (default), not continuous mode.
Continuous mode (.trigger(continuous=...)) only supports at-least-once semantics and lacks full fault- tolerance.
trigger(availableNow=True)is a batch-style trigger, not suited for low-latency streaming.
So:
Option A uses micro-batching with a tight trigger interval # minimal latency + exactly-once guarantee.
Final Answer: A
