최신 Snowflake Certification SPS-C01 무료샘플문제 (Q257-Q262):

질문 # 257
You are developing a Snowpark application that processes large datasets stored in Snowflake. You need to implement custom User-Defined Functions (UDFs) written in Java. The UDF requires specific third-party libraries that are not available in the default Snowflake Java environment. What steps are necessary to package and deploy these UDFs correctly?

A. Create a separate Python UDF that imports the Java code using Jpype and then register the Python UDF with Snowflake
B. Use the 'CREATE OR REPLACE JAVA FUNCTION' command directly in Snowsight and paste the Java code along with the dependencies' contents into the function body.
C. Utilize the Snowpark API to create a 'snowpark.functions.udf object, including the Java code and dependencies. The Snowpark runtime will handle the deployment.
D. Compile the Java code into a native library (e.g., a .so file), upload it to a Snowflake stage, and use the 'CREATE EXTERNAL FUNCTIONS command to invoke it.
E. Package the Java code and dependencies into a JAR file and upload it to a Snowflake stage. Use the 'CREATE FUNCTION' command with the 'IMPORTS' clause to reference the JAR file.

정답：E

설명：
The correct approach involves packaging the Java code and its dependencies into a JAR file, uploading it to a Snowflake stage, and using the 'CREATE FUNCTION' command with the 'IMPORTS clause. This informs Snowflake to include the specified JAR file in the classpath when executing the UDF. Other options are not valid ways to deploy Java UDFs with dependencies in Snowflake.

질문 # 258
You have a Snowpark DataFrame named 'orders df with columns 'order id', 'customer id', 'order date', and 'total amount'. You need to create a new DataFrame that contains only the 'customer_id" and the total number of orders placed by each customer. However, you want to perform this aggregation in parallel using a user-defined function (UDF) to improve performance. Which approach is MOST efficient and CORRECT?

A. Create a UDF that takes an iterator of order IDs and returns the count. Apply this UDF to each partition of the DataFrame using 'maplnPartitions' .
B. Use 'groupBy' to group by 'customer_id' and then use the 'count' aggregate function. Do not use a UDF.
C. Create a UDF that calculates the mode of total_amount, then apply the UDF to the DataFrame using 'select'.
D. Create a UDF that performs the entire aggregation and call it with 'orders_df. The UDF uses a Pandas DataFrame internally to perform the count.
E. Create a UDF that takes a customer ID as input and returns the count of orders for that customer, then apply this UDF to each distinct customer ID using 'map'.

정답：B

설명：
The most efficient and correct approach is to use the built-in 'groupBy' and 'count' functions. These functions are optimized for Snowflake's architecture and will generally outperform UDF-based solutions for simple aggregations. Using UDFs for simple tasks introduces overhead and can negate any potential performance benefits. While options A, B and D could achieve the result, they are less efficient. Option E is irrelevant to the problem.

질문 # 259
You have a Snowpark DataFrame containing sensor data'. You need to write this data to a Snowflake stage 'sensor_stage' , creating a new set of files every hour based on the 'timestamp' column (data type: Timestamp). You also want to ensure that the file names include the hour of the timestamp and are written in Avro format with Zstandard compression. The directory structure on the stage should reflect the hourly partitioning. Which of the following approaches offers the most efficient and scalable way to achieve this, while minimizing the number of files written per hour?

A. Using scala user defined function (UDF) for write dataframe into stage in avro file format partitioned by Hour and calling it in snowpark dataframe.
B. Create a new DataFrame by adding an 'hour' column extracted from the 'timestamp' column. Then use 'df.write.partitionBy('hour').format('avro').option('compression', 'zstd').mode('append').save('@sensor_stage/')'.
C. Define a stored procedure that iterates through hourly intervals, filters the DataFrame based on the current hour, and writes the filtered DataFrame to the stage using 'df.write.format('avro').option('compression', 'zstd').mode('append').save(f'@sensor_stage/hour={current_hour}/')'
D. Create a view on top of the data and schedule a task which create file in avro with zstd compression by running the select statment with group by hour.
E. Write a Python script that connects to Snowflake, retrieves the entire DataFrame, iterates through each row, determines the hour from the 'timestamp', and writes each row to a separate Avro file named after the hour in the 'sensor_stage'

정답：B

설명：
Option A is the most efficient and scalable approach. By creating a new 'hour' column and using 'partitionBy('hour')' , Snowpark will automatically handle the hourly partitioning and create the appropriate directory structure on the stage. The will create new directory if it doesn't exist and write data, 'format('avro')' ensures the data is written as Avro files, and 'option('compression', 'zstd')' enables Zstandard compression. Option B, using a stored procedure with iteration, is less efficient because it requires fetching the data multiple times and performing the filtering within the stored procedure. Option C, writing the file in Scala , requires manage more code and jar file, which is not optimal approach for Snowflake's data storage/processing mechanism. Option D is highly inefficient as it involves retrieving the entire DataFrame into the client's memory and writing each row separately, negating the benefits of Snowpark's distributed processing. Option E creates another object in snowfalke, so that can be avoided.

질문 # 260
You are using Snowpark Python to process a DataFrame containing customer data,. One of the columns, 'phone_number' , contains phone numbers in various formats (e.g., '123-456-7890', '(123) 456-7890', '1234567890'). You need to standardize these phone numbers to the format 'XXX-XXX-XXXX' using a User-Defined Function (UDF). You want to create a UDF called 'standardize_phone_number' that takes a string as input and returns the standardized phone number. Which of the following code snippets correctly defines and registers this UDF in Snowpark, and applies it to the 'phone_number' column of the 'customer df DataFrame? Assume a Snowflake session object called 'session' is already available.

정답：C

설명：
Option E is the most concise and correct way to define and use the UDF. It uses the '@F.udf decorator, which simplifies the UDF registration process. It also correctly imports 'snowflake.snowpark.functions as F to use the decorator. Options A and D are less efficient because they use 'call_udf instead of directly calling the UDF. Option B registers UDF but does not import required libraries. Option C doesn't import necessary library for the functions.

질문 # 261
You have a Snowpark DataFrame containing data to be loaded into a Snowflake table You want to use the 'merge' operation to update existing records and insert new records. The has a column (BOOLEAN) that indicates whether a record should be updated (TRUE) or inserted (FALSE) if it doesn't already exist. Which of the following SQL expressions correctly implement this logic within the 'merge' operation's 'WHEN MATCHED' and 'WHEN NOT MATCHED' clauses?

A. WHEN MATCHED AND = TRUE THEN UPDATE SET target_table.columnl = staging_df.columnl WHEN NOT MATCHED AND = FALSE THEN INSERT (columni) VALUES (staging_df.columnl)
B. WHEN MATCHED THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED THEN INSERT (columni) VALUES (staging_df.columnl)
C. WHEN MATCHED AND = TRUE THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED AND = FALSE THEN INSERT (columni) VALUES (staging_df.columnl)
D. WHEN MATCHED AND THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED AND NOT THEN INSERT (columni) VALUES (staging_df.columnl)
E. WHEN MATCHED THEN UPDATE SET target_table.columnl = staging_df.columnl WHEN NOT MATCHED THEN INSERT (columni) VALUES (staging_df.columnl )

정답：D

설명：
The correct SQL expression utilizes the column within the 'WHEN MATCHED and 'WHEN NOT MATCHED clauses to conditionally determine whether to update or insert a record. Option E correctly checks the for 'TRUE in the 'WHEN MATCHED' clause and 'FALSE' in the 'WHEN NOT MATCHED clause to conditionally trigger the 'UPDATE' and 'INSERT operations, respectively. It uses Boolean algebra directly for concise condition checking. When the update_flag is True the update is executed, when false it is inserted. This implementation allows for a single 'merge' statement to handle both update and insert operations based on a flag within the staging data.
