Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q110-Q115):

NEW QUESTION # 110
A data engineering team is building a Snowpark pipeline to process IoT sensor data'. They want to create a UDF that uses a 3rd-party Python library (not available in Snowflake's Anaconda channel) to analyze the sensor readings. The UDF needs to be efficiently deployed and managed within Snowflake. Which of the following approaches represents the MOST robust and scalable way to register and deploy this UDF using Snowpark?

A. Use 'functions.udf and directly embed the package code within the UDF definition. This approach handles package management automatically.
B. Create a virtual environment with the necessary Python library, zip it, upload the zip file to a Snowflake stage, and use to register the UDF. Reference the stage location and virtual environment in the register call.
C. Use 'session.add_packages' to add the specific Python package directly from the Snowflake Anaconda channel (even if the required version isn't available) and then use 'session.udf.register' for the UDF definition.
D. Use 'session.udf.register' and directly include the library code as a string within the UDF definition. This avoids external dependencies.
E. Create a Docker container with the Python library, push it to Snowflake Container Services, and call this container from the UDF.

Answer: B

Explanation:
Option B is the correct answer. It describes the best practice for deploying UDFs with external Python libraries in Snowflake. Creating a virtual environment, zipping it, uploading it to a stage, and referencing it during UDF registration ensures proper dependency management and avoids conflicts. Option A is problematic because embedding the library directly makes the UDF definition very large and unmanageable. Option C will not work if the required version isn't available. Option D is incorrect because functions.udf relies on packages available in the Snowflake Anaconda channel and doesn't manage custom packages. While Option E could work, its overly complex for this specific scenario compared to utilizing Snowpark virtual enviornment and stage management. Option B is more efficient and streamlined.

NEW QUESTION # 111
Consider the following scenario: You need to implement a UDF in Snowpark Python to calculate the distance between two geographical coordinates (latitude and longitude). The UDF should handle potential null values gracefully and return null if either input coordinate is null. Which code snippet demonstrates the MOST efficient and correct implementation, leveraging Snowpark's capabilities?

Answer: E

Explanation:
Option E is the most efficient and correct. It uses 'F.when' and 'F.lit(NoneV (from the 'snowflake.snowpark.functions' module) to handle null values within the Snowpark expression tree. This allows Snowflake to optimize the null handling during query execution. The function is also properly typed using type hints, enhancing readability. By wrapping the 'haversine_udf with null check logic using 'when' and 'otherwise' from 'snowflake.snowpark.functions' , the check is performed server-side along with rest of the query execution, leveraging Snowflake's optimization engine.

NEW QUESTION # 112
You need to create a Snowpark DataFrame using a SQL query. The query requires a user-defined variable (e.g., a date for filtering records). What are the correct and recommended ways to safely pass this variable into the SQL query when creating the DataFrame using 'session.sql()' to prevent SQL injection vulnerabilities?

Answer: B,E

Explanation:
Options C and E are the safest and recommended approaches. Option C, if supported by your Snowpark version, uses parameterized SQL queries, which are the best way to prevent SQL injection. Option E avoids injecting the variable into the SQL string at all by filtering in Snowpark after the DataFrame is created. Options A and B are highly vulnerable to SQL injection. Option D is better than A and B, but still less secure and more complex than using parameterized queries or filtering with the DataFrame API.

NEW QUESTION # 113
You have a Snowpark Python UDTF named that performs complex data transformations and you want to share it securely with another Snowflake account. Select ALL the necessary steps and considerations to properly share this UDTF using Snowflake Secure Data Sharing.

A. Create a secure UDTF and add it to share.
B. Ensure the UDTF doesn't rely on any external packages or dependencies not available in the target account.
C. Grant SELECT privilege on the UDTF to the share.
D. Create a share and grant usage on the database containing the 'process_data' UDTF to the share.
E. Grant OWNERSHIP privilege on the UDTF to the share.

Answer: A,B,C,D

Explanation:
To share a UDTF, you first create a share and grant USAGE on the database containing it (A). Then, you create the UDTF as SECURE to ensure data is protected (B). SELECT is needed to allow the share to actually use the function (C). It is important to make sure that the receiving account will be able to run the UDTF, so ensure all of the needed packages and dependendies are accounted for (D). GRANT OWNERSHIP would mean you would not be able to make changes to the function (E).

NEW QUESTION # 114
A data engineering team is developing a Snowpark stored procedure to perform complex data transformations and load the results into a target table. They want to operationalize this procedure by scheduling it to run daily. Which of the following is the MOST reliable and scalable way to schedule the execution of this Snowpark stored procedure within Snowflake?

A. Utilize a third-party orchestration tool, such as Airflow, to schedule and monitor the execution of the stored procedure through the Snowflake connector.
B. Use Snowflake Tasks to schedule a SQL statement that calls the stored procedure.
C. Use Snowflake Pipes to ingest data and trigger the stored procedure based on new data arrival.
D. Create a Python script that uses the Snowpark API to connect to Snowflake and execute the stored procedure, then schedule the script using a Linux cron job.
E. Implement a Streamlit application that calls the stored procedure when a button is pressed.

Answer: B

Explanation:
Snowflake Tasks are the recommended way to schedule stored procedures within Snowflake. They are a native Snowflake feature, providing scalability, reliability, and integration with Snowflake's monitoring and management tools. Airflow is a valid option, but adds external dependencies.
