Databricks Certified Associate Developer for Apache Spark 3.5 - Python Sample Questions (Q53-Q58):

NEW QUESTION # 53
Given this code:

.withWatermark("event_time","10 minutes")
.groupBy(window("event_time","15 minutes"))
.count()
What happens to data that arrives after the watermark threshold?
Options:

A. Data arriving more than 10 minutes after the latest watermark will still be included in the aggregation but will be placed into the next window.
B. The watermark ensures that late data arriving within 10 minutes of the latest event_time will be processed and included in the windowed aggregation.
C. Any data arriving more than 10 minutes after the watermark threshold will be ignored and not included in the aggregation.
D. Records that arrive later than the watermark threshold (10 minutes) will automatically be included in the aggregation if they fall within the 15-minute window.

Answer: C

Explanation:
According to Spark's watermarking rules:
"Records that are older than the watermark (event time < current watermark) are considered too late and are dropped." So, if a record'sevent_timeis earlier than (max event_time seen so far - 10 minutes), it is discarded.

NEW QUESTION # 54
A developer wants to test Spark Connect with an existing Spark application.
What are the two alternative ways the developer can start a local Spark Connect server without changing their existing application code? (Choose 2 answers)

A. Set the environment variableSPARK_REMOTE="sc://localhost"before starting the pyspark shell
B. Ensure the Spark propertyspark.connect.grpc.binding.portis set to 15002 in the application code
C. Execute their pyspark shell with the option--remote "https://localhost"
D. Add.remote("sc://localhost")to their SparkSession.builder calls in their Spark code
E. Execute their pyspark shell with the option--remote "sc://localhost"

Answer: A,E

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Spark Connect enables decoupling of the client and Spark driver processes, allowing remote access. Spark supports configuring the remote Spark Connect server in multiple ways:
From Databricks and Spark documentation:
Option B (--remote "sc://localhost") is a valid command-line argument for thepysparkshell to connect using Spark Connect.
Option C (settingSPARK_REMOTEenvironment variable) is also a supported method to configure the remote endpoint.
Option A is incorrect because Spark Connect uses thesc://protocol, nothttps://.
Option D requires modifying the code, which the question explicitly avoids.
Option E configures the port on the server side but doesn't start a client connection.
Final Answers: B and C

NEW QUESTION # 55
A data engineer needs to write a Streaming DataFrame as Parquet files.
Given the code:

Which code fragment should be inserted to meet the requirement?
A)

Which code fragment should be inserted to meet the requirement?

A. .format("parquet")
.option("location", "path/to/destination/dir")
B. CopyEdit
.option("format", "parquet")
.option("destination", "path/to/destination/dir")
C. .format("parquet")
.option("path", "path/to/destination/dir")
D. .option("format", "parquet")
.option("location", "path/to/destination/dir")

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To write a structured streaming DataFrame to Parquet files, the correct way to specify the format and output directory is:
writeStream
format("parquet")
option("path", "path/to/destination/dir")
According to Spark documentation:
"When writing to file-based sinks (like Parquet), you must specify the path using the .option("path", ...) method. Unlike batch writes, .save() is not supported." Option A incorrectly uses.option("location", ...)(invalid for Parquet sink).
Option B incorrectly sets the format via.option("format", ...), which is not the correct method.
Option C repeats the same issue.
Option D is correct:.format("parquet")+.option("path", ...)is the required syntax.
Final Answer: D

NEW QUESTION # 56
Given a DataFramedfthat has 10 partitions, after running the code:
result = df.coalesce(20)
How many partitions will the result DataFrame have?

A. 0
B. 1
C. 2
D. Same number as the cluster executors

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The.coalesce(numPartitions)function is used to reduce the number of partitions in a DataFrame. It does not increase the number of partitions. If the specified number of partitions is greater than the current number, it will not have any effect.
From the official Spark documentation:
"coalesce() results in a narrow dependency, e.g. if you go from 1000 partitions to 100 partitions, there will not be a shuffle, instead each of the 100 new partitions will claim one or more of the current partitions." However, if you try to increase partitions using coalesce (e.g., from 10 to 20), the number of partitions remains unchanged.
Hence,df.coalesce(20)will still return a DataFrame with 10 partitions.
Reference: Apache Spark 3.5 Programming Guide # RDD and DataFrame Operations # coalesce()

NEW QUESTION # 57
A developer is trying to join two tables,sales.purchases_fctandsales.customer_dim, using the following code:

fact_df = purch_df.join(cust_df, F.col('customer_id') == F.col('custid')) The developer has discovered that customers in thepurchases_fcttable that do not exist in thecustomer_dimtable are being dropped from the joined table.
Which change should be made to the code to stop these customer records from being dropped?

A. fact_df = purch_df.join(cust_df, F.col('cust_id') == F.col('customer_id'))
B. fact_df = purch_df.join(cust_df, F.col('customer_id') == F.col('custid'), 'right_outer')
C. fact_df = purch_df.join(cust_df, F.col('customer_id') == F.col('custid'), 'left')
D. fact_df = cust_df.join(purch_df, F.col('customer_id') == F.col('custid'))

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In Spark, the default join type is an inner join, which returns only the rows with matching keys in both DataFrames. To retain all records from the left DataFrame (purch_df) and include matching records from the right DataFrame (cust_df), a left outer join should be used.
By specifying the join type as'left', the modified code ensures that all records frompurch_dfare preserved, and matching records fromcust_dfare included. Records inpurch_dfwithout a corresponding match incust_dfwill havenullvalues for the columns fromcust_df.
This approach is consistent with standard SQL join operations and is supported in PySpark's DataFrame API.
