Study with NAS-C01 Actual Test Questions

You are developing a Streamlit application within a Snowflake Native App that needs to access a custom Python module ('my_module.py') containing utility functions. The module resides in the same stage as your Streamlit application code. How would you ensure that the Streamlit application can correctly import and use this module?

• A. Place 'my_module.py' in the same directory as your main Streamlit application file. Snowflake automatically includes all files in the same directory when deploying the application.
• B. Modify the ' PYTHONPATHS environment variable within the Snowflake environment to include the stage where 'my_module.py' is located.
• C. Use the function to dynamically load 'my_module.py' directly from the stage, specifying the full stage path.
• D. Use the method in your Streamlit application code to add the stage location to the Python module search path before importing my_module' .
• E. Include in a 'requirements.txt' file and use 'pip install -r requirements.txt' within the Streamlit application's entrypoint script.

You are developing a Snowflake Native Application that includes a Python module for data transformation. This module relies on the pandas' and 'requests' libraries. You are using an 'environment.yml' file to manage dependencies. Which of the following 'environment.yml' configurations is the MOST secure and correct way to define these dependencies for your application? Assume you want to install these packages directly from conda-forge channel.

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

You are developing a Snowflake Native App that utilizes Streamlit for its user interface. You want to control the app's behavior based on whether it's running in a development environment within your provider account or in a consumer account after installation. Which of the following methods can you use within your 'streamlit.py' to determine the current execution context (Provider vs. Consumer) reliably?

• A. Use which is a function specifically designed to check if the app is running in a consumer account.
• B. Examine the session context function 'CURRENT ACCOUNT()' function and compare it with the provider account identifier, if matches then it is a provider. It is the best method.
• C. Query the view. Presence in this view indicates a provider environment.
• D. Read an environment variable set during the application installation process by the consumer.

You are developing a Snowflake Native Application that leverages Snowflake Event Tables to log application events. You notice that while the application is successfully writing events to the event table, consumers are reporting that they cannot query the event table. Assume that you have successfully implemented the logging mechanism in your code and data is being logged. Consider the following manifest section:

Which of the following steps is MOST critical to resolve this issue and ensure consumers can query the event table?

• A. Verify that the application role defined in the application manifest has been granted the 'SELECT privilege on the event table within the provider account.
• B. Confirm that the event table is explicitly listed in the 'shared_objects' section of the application manifest with the correct 'object_name', 'source_type' set to event_table', and 'privileges' including 'SELECT'.
• C. Grant the 'APPLY MASKING POLICY privilege to the application role on the event table to enable consumers to see masked data, and the REFERENCE_USAGE privilege on the database and schema that contains the event table.
• D. The correct approach is not listed, as consumers cannot directly query event tables associated with Snowflake Native Applications for security reasons.
• E. Ensure that the consumer account has the 'MONITOR privilege on the application, as this is required to query event tables associated with native applications.

You are packaging a Snowflake Native App for distribution. Which of the following artifacts are essential components of the application bundle that must be included?

• A. Compiled Java JAR files if the app includes Java UDFs.
• B. The manifest file (snowflake.yml).
• C. The application's source code (e.g., SQL scripts, Python files).
• D. The 'setup.sql file containing the application's initialization logic.
• E. Binary executables compiled for a specific operating system.
