You are tasked with building a Snowpark application that processes sensor data. The data arrives continuously and is ingested into a Snowflake table called 'RAW SENSOR DATA'. You need to create a Snowpark DataFrame that applies a user-defined function (UDF) to each row to enrich the data. The UDF, named 'ENRICH SENSOR DATA, is written in Python and resides in a stage called 'UDF STAGE. The UDF takes three arguments: 'timestamp', and 'raw_value', all of which are STRING type in Snowflake. Which of the following code snippets correctly defines and calls the UDF using Snowpark?

• A.
  
• B.
  
• C.
  
• D.
  
• E.
  

You have developed a Python function that performs complex data transformation on customer data'. You want to operationalize this function as a UDTF in Snowpark to process large datasets efficiently. The function takes a customer ID and a list of transaction amounts as input and returns a table with calculated risk scores for each transaction. Which of the following code snippets correctly defines and registers this UDTF in Snowpark, ensuring proper type handling and scalability?

• A.
  
• B.
  
• C. Options B and C are the most correct.
• D.
  
• E.
  

A data engineering team is developing a Snowpark application that processes large volumes of JSON data'. They have created a UDF using Python that parses JSON strings and extracts specific fields. They need to deploy this UDF and ensure it can handle malformed JSON without causing the entire Snowpark job to fail. Which of the following strategies BEST addresses both the deployment and error handling requirements?

• A. Create a Java UDF instead of Python. Java has better JSON parsing libraries. Upload the JAR file to a stage and register the UDF with 'imports' clause referencing the JAR file. Use try-catch for error handling.
• B. Create a Python UDF using the 'snowflake-snowpark-python' library and register it in Snowflake. Implement error handling using 'try-except block within the UDF to catch 'json.JSONDecodeError' exceptions and return NULL. Package the Python code as a ZIP file containing any necessary dependencies and upload it to a stage, using the 'imports' clause in the UDF definition.
• C. Create a Python UDF and register it in Snowflake, using 'try-except' block within the UDF to catch 'json.JSONDecodeError' exceptions. Package the Python code with the 'snowflake-snowpark-python' library.
• D. Create an external function pointing to an AWS Lambda function that handles the JSON parsing. Configure the Lambda function to retry on failure, using SNS for notifications. No need to use ZIP file or any 'imports' clause.
• E. Create a Python UDF using the 'snowflake-snowpark-python' library and register it in Snowflake. Implement error handling using Snowflake's built-in 'ERROR HANDLING' clause in the 'CREATE FUNCTION' statement. Package the Python code as a ZIP file and upload it to a stage, using the 'imports' clause in the UDF definition.

You are developing a Snowpark Python UDF to perform sentiment analysis on product reviews. The UDF takes a text review (STRING) as input and returns a sentiment score (FLOAT). You want to operationalize this UDF, ensuring type safety and performance. Which of the following approaches is MOST recommended, considering both ease of use and explicit type declaration?

• A. Using gudf(return_type=FloatType(), decorator with explicit data type registration.
• B.
  
• C. Using Python type hints alone: 'def sentiment_score(review: str) -> float: .... and relying on Snowpark to infer types.
• D. Using only the function name without any explicit type declaration or registration.
• E. Casting the result of the UDF to FLOAT within the UDF definition.

Consider a Snowflake table 'sales_data' with a VARIANT column 'order_details' containing an array of JSON objects, where each object represents an item in an order. Each item object has fields like 'quantity', and 'price'. You need to calculate the total price for each order by summing the product of 'quantity' and 'price' for all items in the 'order_details' array. Which of the following Snowpark Python snippets correctly accomplishes this?

• A.
  
• B.
  
• C.
  
• D.
  
• E.
