問題6
A data scientist has developed a complex machine learning model in Python that needs to be operationalized within a Snowpark pipeline. This model depends on several custom Python packages not available in Snowflake's default environment. The data scientist wants to define a UDTF to apply this model to incoming data'. Which of the following steps are NECESSARY to successfully deploy and execute this UDTF in Snowflake? (Select three)

Consider the following Snowpark Python code snippet that retrieves data and calculates aggregate values, however, the application performance is slow when you are fetching dataframe, given the 'block' parameter controls the synchronous/asynchronous behavior of the 'collect()' method. Choose ALL the statements about "session.create_dataframe([rowl ,row2],schema)' that are correct:

問題8
You're developing a Snowpark Python application that reads data from a Snowflake table, performs several transformations, and writes the result to another table. You notice that the application throws a 'net.snowflake.snowpark.exceptions.SnowparkClientException: JDBC driver encountered an unexpected error.' intermittently. Examining the Snowflake query history, you observe many queries failing due to 'Warehouse Suspended'. Which of the following strategies would BEST address this issue in a production environment?

問題9
You are developing a Snowpark application to process sales data. The application uses a UDF that calls an external Python library with a large memory footprint. After deploying the application, you observe that the Snowflake warehouse frequently runs out of memory, causing the application to fail. Which of the following strategies would be MOST effective in mitigating this issue, while minimizing cost and maintaining performance? Assume the data volume is relatively large and the UDF is computationally intensive.
