Which of the following Snowpark Python code snippets correctly implements this rolling average calculation using a table function?

Q52. You are tasked with creating a Snowpark UDTF (User-Defined Table Function) in Python to process a large CSV file stored in a Snowflake stage. Each row in the CSV represents a transaction, and you need to parse each row and extract specific fields based on a complex set of rules. The UDTF should return a table with the extracted fields. Consider the following code snippet:

Q53. You have a Snowpark DataFrame ‘df sales’ containing sales data with columns like ‘order id’, ‘product id’, ‘quantity’, and ‘sale_price’ You want to persist this data into a Snowflake table named “SALES DATA’. You also want to create a dynamic table on top of this base table for faster analytics. You need to choose the appropriate persistence strategy and consider the implications of using a dynamic table. Which of the following options represents the BEST approach?

Q54. You’re tasked with loading data representing transactions from a legacy system into Snowflake using Snowpark. The legacy system exports the transaction data as a Python list of tuples, where each tuple contains transaction ID (integer), transaction amount (float), and transaction date (string in ‘YYYY-MM-DD’ format). The scale of data can be very high and need optimized way to load the data’. Your goal is to create a Snowpark DataFrame from this list of tuples, ensuring the date column is correctly interpreted as a Snowflake Date type. Which of the following approaches would be the most efficient and correct, minimizing data conversion overhead and maximizing Snowpark’s capabilities?

Q55. You are developing a Snowpark Python application that reads a large dataset (1 TB) from a Snowflake table ‘TRANSACTIONS and performs complex aggregations. The application is experiencing significant performance issues, with query execution taking several hours. You have already verified that the warehouse size is appropriate and caching is enabled. You suspect the issue might be related to data skew and incorrect partitioning. Which of the following strategies would be MOST effective in identifying and mitigating this performance bottleneck?

Q56. Consider the following Snowpark Python code snippet:

Q57. You are developing a Snowpark application to process large datasets stored in Snowflake. You need to create a session using the ‘snowflake.connector.connect’ method. Which of the following code snippets correctly establishes a session with Snowflake, leveraging an external browser authentication mechanism, ensuring secure and reliable access to your data while minimizing exposed credentials in the code?

Q58. You are tasked with deploying a set of Python UDFs and UDTFs to a Snowflake environment using Snowpark. These functions rely on several external Python packages and need to be versioned and managed effectively. Which of the following strategies provides the MOST robust and scalable solution for managing dependencies and deploying these functions in a reproducible manner?

Q59. Consider the following Snowpark Python code snippet designed to calculate the moving average of sales data’. You’ve identified that the code is performing poorly and suspect the window function is a bottleneck. How can you optimize this code for better performance?

Q60. A financial firm is using Snowpark Python to analyze stock trading data’. They have a DataFrame named ‘trades’ with columns ‘trade_id’, ‘stock_symbol’, ‘trade_price’, and ‘trade_timestamp’. They want to identify potentially fraudulent trades based on the following criteria: 1. Trades where the ‘trade_price’ deviates significantly from the average price of that ‘stock_symbol’ over the past hour. 2. Trades originating from user accounts where the price is above $1000.3. Trades which has stock symbol ‘XYZ’. The firm wants to apply multiple filters to the DataFrame to extract only the fraudulent trades and needs an efficient and concise approach using Snowpark. Which of the following code snippets, using ‘trade_price’ > 1000 as user identifier, MOST accurately and efficiently implements this filtering logic? Assume that a Snowflake user has a maximum amount they can spend on a trade, and therefore, the user ID is associated with ‘trade_price’.

Q61. You are using Snowpark Python to analyze sales data stored in a Snowflake table named ‘SALES DATA. The table has columns PRODUCT ICY, ‘REGION’, and ‘SALE DATE. You need to calculate the total sale amount for each product in each region. You intend to use the ‘group_by’ and ‘agg’ functions. Which of the following Snowpark Python code snippets correctly performs this aggregation and renames the aggregated column to ‘TOTAL SALES’? (Assume ‘session’ is a valid Snowpark session object.)

Q62. Consider a Snowflake table named ‘raw events’ containing web event data in a VARIANT column called ‘event data’. Each ‘event_data’ JSON object may contain an array of product IDs under the key ‘product_ids’, and another array of user IDs who interacted with those products under the key ‘user_ids’. These arrays are not guaranteed to be the same length, and a missing array should be handled gracefully (return null/empty result for that row rather than throwing error). Your objective is to create a Snowpark DataFrame that flattens both arrays into rows, pairing each product ID with each user ID for the specific event, generating as many rows as possible, and including event timestamp. You can use a zero-based index for the array elements using ‘ARRAY CONSTRUCT()’ and then using that array for using the EXPLODE function. Which of the following are necessary steps to fulfill this requirement and which are not?

Q63. You are tasked with optimizing a Snowpark Python application that performs complex geospatial calculations on a large dataset. The application experiences significant performance bottlenecks due to the computational intensity of the geospatial functions. Which of the following strategies would be MOST effective in improving performance?

Q64. You have developed a Snowpark Python application that needs to connect to an external REST API to enrich data during a transformation. The API requires authentication using an API key stored securely. Which of the following approaches is the MOST secure and recommended way to manage the API key within the Snowpark environment?

Q65. You are tasked with operationalizing a Snowpark Python UDF for batch scoring of a large dataset. The UDF takes a set of feature columns and returns a prediction. You want to optimize performance and resource utilization. Select all the strategies that would effectively improve the operational efficiency and scalability of your UDF execution.

Q66. You have a Snowpark DataFrame named ‘orders_df with columns ‘order_id’, ‘customer_id’, ‘order_date’, and ‘order_total’. You need to perform the following data enrichment steps using Snowpark for Python: 1. Calculate the ‘year’ from the ‘order_date’ column. 2. Calculate the ‘discounted_total’ by applying a discount of 10% if the ‘order_total’ is greater than $100, otherwise, no discount. 3. Create a new column ‘customer_tier’ based on the total spend per customer for each year. Customers with total spend greater than $1000 are ‘Gold’, between $500 and $1000 are ‘Silver’, and below $500 are ‘Bronze’. Which of the following code snippets correctly implements these data enrichment steps using Snowpark (Assume the existence of a customer total spend df DataFrame).
