Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q228-Q233):

NEW QUESTION # 228
Consider the following Snowpark Python code snippet designed to aggregate sales data by region:

During testing, you observe that the performance of this code is suboptimal, especially when dealing with very large 'SALES DATA tables. Using Snowflake's query history, you notice that a significant amount of time is spent on data shuffling during the operation. What optimization strategies could you employ within this Snowpark code to minimize data shuffling and improve the overall performance?

A. store 'SALES_DATX as a clustered table using the 'REGION' column.
B. Apply a more selective 'filter operation to the 'sales_df' DataFrame before the 'groupBy' operation, reducing the amount of data that needs to be shuffled.
C. Utilize the 'hint' function in Snowpark to provide a join hint that suggests a specific join strategy to the Snowflake query optimizer.
D. Increase the warehouse size to provide more resources for data processing, which will inherently reduce data shuffling.
E. Repartition the 'sales_df DataFrame using 'repartitionBy' before the 'groupBy' operation, specifying the 'REGION' column to ensure that data for each region is co-located on the same node.

Answer: A,B,E

Explanation:
Filtering early reduces data shuffling by reducing the volume of data that needs to be grouped. Repartitioning ensures that rows with the same region are on the same node before the group by which reduces shuffling significantly. Creating the source SALES_DATA table as a clustered table with REGION as the clustering key colocates the data for each region in the same micropartitions, reducing shuffling. Increasing warehouse size will help overall performance but will not directly reduce shuffling. Hints apply to Joins, not group by operations.

NEW QUESTION # 229
You are using Snowpark Python to build a data pipeline. You need to version control your Snowpark application and ensure that it is compatible with different Snowflake environments (development, staging, production). Which strategies and tools would be most effective for managing the Snowpark application's code, dependencies, and deployment process?

A. Rely solely on Snowflake's built-in Python interpreter and avoid using any external libraries or dependencies to simplify versioning and deployment.
B. Package all Snowpark code into a single ZIP file and manually upload it to each environment.
C. Use a Git repository to manage the Snowpark Python code, a dependency management tool like Poetry or pip to handle dependencies, and a CI/CD pipeline (e.g., using Jenkins or GitLab CI) to automate deployment to different Snowflake environments.
D. Copy and paste the Python code between different Snowflake environments as needed, manually installing any required dependencies.
E. Store the Python code directly in Snowflake stages and use Snowflake's versioning capabilities to manage different versions.

Answer: C

Explanation:
Using a Git repository for version control, a dependency management tool like Poetry or pip, and a CI/CD pipeline is the recommended approach for managing Snowpark applications. This allows for proper version control, dependency management, and automated deployment across different environments. The other options represent less robust and error-prone approaches.

NEW QUESTION # 230
You have a Snowpark DataFrame named 'sales df containing sales data for different products. The DataFrame includes columns product_id' (INTEGER), 'sale_date' (DATE), 'quantity' (INTEGER), and 'price' (FLOAT). You need to calculate the total revenue for each product on a monthly basis and store the result in a new DataFrame named Which of the following Snowpark code snippets will correctly achieve this, while maximizing performance and minimizing data shuffling?

A. ...python from snowflake.snowpark.functions import month, sum monthly_revenue_df = sales_df.groupBy('product_id', month('sale_date').alias('sale_month')).agg(sum(sales_df['quantity'l sales_df['price']).alias('total_revenue'))
B. ...python from snowflake.snowpark.functions import date_format, sum monthly_revenue_df = sales_df.withColumn('sale_month', date_format(sales_df['sale_date'], 'yyyy-MM')).groupBy('product_id', 'sale_month').agg(sum(sales_df['quantity'] sales_df['price']).alias('total_revenue'))
C. ...python from snowflake.snowpark.functions import to_date, date_trunc, sum monthly_revenue_df = sales_df.withColumn('sale_month', date_trunc('MM', sales_df['sale_date'])).groupBy('product_id', 'sale_month').agg(sum(sales_df['quantity'] sales_df['price']).alias('total_revenue'))
D. ...python from snowflake.snowpark.functions import date_part, sum monthly_revenue_df = sales_df.groupBy('product_id', date_part('month', 'sale_date').alias('sale_month')).agg(sum(sales_df['quantity'] sales_df['price']).alias('total_revenue'))
E. ...python from snowflake.snowpark.functions import monthname, sum monthly_revenue_df = sales_df.groupBy('product_id', monthname('sale_date').alias('sale_month')).agg(sum(sales_dfl'quantity'] sales_dfl'price']).alias('total_revenue'))

Answer: C

Explanation:
Option B is the most efficient because 'date_trunc('MM', ...y truncates the date to the beginning of the month, allowing for proper grouping and aggregation without unnecessary string conversions or data shuffling. The 'date_trunc' function leverages Snowflake's internal date functions for optimal performance. Other options either use string representations of dates or date parts, which can lead to less efficient grouping.

NEW QUESTION # 231
You have a DataFrame 'df in Snowpark containing order data, including a VARIANT column named 'order details'. The 'order detailS column contains a nested JSON structure with fields like 'customer id' (always a string), 'items' (an array of item IDs, sometimes numbers, sometimes strings), and 'total amount' (inconsistent data type - sometimes string, sometimes number). You need to perform the following transformations: 1. Extract the "customer_id' and cast it to an integer. 2. Extract the first item ID from the 'items' array, attempting to cast it to an integer, handling potential casting errors. 3. Extract the 'total_amount' and cast it to a decimal (precision 10, scale 2), handling potential casting errors. Which of the following code snippets correctly implements these transformations using Snowpark?

Answer: C

Explanation:
Option D correctly implements the required transformations: Since 'customer_id' is always a string, but should be converted to Integer, we can directly cast. is used for to handle cases where the item ID might not be a valid number. 10, is used for 'total_amount' to handle potential casting errors and to cast as decimal with precision 10 and scale 2 Options A, B, C, and E will fail when the values are incorrect data types, they do not perform handle exceptions.

NEW QUESTION # 232
You have a Snowflake table 'orders_json' with a VARIANT column named "order details'. This column contains JSON objects, and one of the fields within these objects is an array called 'items'. You need to use Snowpark to flatten the 'items' array into rows, extracting the 'item_id' , 'item_name' , and 'quantity' from each item in the array. Which of the following Snowpark code snippets will correctly achieve this, assuming 'df is a DataFrame representing 'orders_json'?

Answer: D

Explanation:
Option E is correct because it first extracts the 'items' array into a new column 'items_array' using 'withColumn' . Then, it uses the explode' function to flatten the array into rows, aliasing the exploded column as 'item'. Finally, it selects the desired fields 'item_name' , quantity') from the 'item' column using 'getltem'.
