Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application that relies on external Python packages. You've successfully added the necessary packages to the stage associated with your application package using 'snowflake-cli' during development. However, when testing the application in a consumer account, you encounter errors indicating that these packages are not found. What are the most likely reasons for this issue and how can you resolve them?

A) The consumer account's Python environment is incompatible with the packages used by the application. Instruct the consumer to update their Python environment to match the application's requirements.
B) The 'snowflake.yml' file does not correctly specify the stage where the Python packages are located. Update the 'snowflake.yml' file to include the correct stage URL and ensure the application's setup script creates the stage and uploads the packages.
C) The stage is not automatically shared with the consumer account as part of the application package. Ensure that your setup script includes a step to create a share and grant usage on the stage to the consumer account.
D) The consumer account does not have access to the Snowflake Marketplace where the packages are hosted. Request the consumer to enable access to the required marketplace listings.
E) The packages were not correctly added to the stage. Verify that the packages are in the stage specified in the 'snowflake.yml' file, and that the application has the necessary permissions to read from the stage within the setup script.

2. You are developing a Snowflake Native Application intended for the Snowflake Marketplace. Before listing your application, you want to ensure it adheres to Snowflake's best practices for security, performance, and usability. Which of the following steps should you take to validate your application prior to submission? (Choose three)

A) Deploy the application to a separate Snowflake account and simulate user interactions to validate the application's usability and functionality.
B) Manually review the application code to identify potential SQL injection vulnerabilities and optimize query performance.
C) Use Snowflake's built-in code scanning tools (if available in the future) to automatically identify security vulnerabilities and code quality issues.
D) Conduct thorough testing of the application on various Snowflake editions and sizes to ensure scalability and performance across different environments.
E) Submit your application code to a third-party security auditing firm for a comprehensive vulnerability assessment.

3. You are developing a Snowflake Native App that leverages shared data from the consumer's account. The app needs to dynamically determine the existence of a specific table (e.g., 'CUSTOMER DATA) in the consumer's shared database before attempting to query it. Which of the following SQL commands or approaches within the application package provides the MOST reliable way to programmatically check for the existence of the table?

A) Execute a 'SELECT 1 FROM CUSTOMER_DATA LIMIT 1' query within a 'TRY...CATCH' block and handle the exception if the table does not exist.
B) Use the ' SHOW TABLES LIKE 'CUSTOMER_DATA" command and check if any rows are returned.
C) Use the 'INFORMATION SCHEMA.TABLES' view and query it to check if a table with the name 'CUSTOMER DATA' exists in the shared database.
D) Use the 'DESCRIBE TABLE CUSTOMER_DATX command within a 'TRY...CATCH' block and handle the exception if the table does not exist.
E) Attempt to grant SELECT privilege on the table and check if an error occurs

4. You are developing a Snowflake Native Application that processes customer dat a. To comply with data residency requirements, you need to ensure the application processes data within the customer's Snowflake account. The application logic resides in a Snowpark Python stored procedure. During development, you test this procedure using the 'CALL' command. However, after installing the application in a customer's account, the procedure fails with a 'privilege insufficient' error. What are the MOST likely reasons for this and how can you rectify them within the package definition?

A) The procedure owner is not the application. This can be resolved by transferring ownership to the application role using 'ALTER PROCEDURE (...) OWNER TO APPLICATION ROLE in the setup script.
B) The application role lacks sufficient privileges on the data sources within the customer's account. Grant the appropriate privileges (e.g., 'SELECT , 'INSERT) on the required tables/views to the application role in the setup script using 'GRANT SELECT ON TABLE TO APPLICATION ROLE
C) The application manifest is missing the 'external_network_accesS property set to 'true'. Add this to the manifest and use network rules if the application requires access to external resources.
D) The stored procedure is missing the EXECUTE MANAGED ACCOUNT privilege. Add 'GRANT EXECUTE MANAGED ACCOUNT ON PROCEDURE TO APPLICATION ROLE to the setup script.
E) The stored procedure requires the 'IMPORTED PRIVILEGES on the database. Grant this using 'GRANT IMPORTED PRIVILEGES ON DATABASE TO APPLICATION ROLE in the setup script.

5. You are preparing to publish a Snowflake Native Application on the Snowflake Marketplace. You have successfully built and tested the application in your development account. Which of the following steps are CRITICAL for preparing the application listing metadata and ensuring a smooth onboarding experience for consumers?

A) Define a clear pricing model (e.g., free, per-use, subscription) and accurately estimate the resource consumption (Snowflake credits) required for typical application usage. Include a free trial period if possible.
B) Provide a comprehensive and user-friendly application description that clearly outlines the application's functionality, benefits, and intended use cases. Include screenshots and/or videos demonstrating the application in action.
C) Ensure all necessary data governance and security measures are in place, including compliance with relevant regulations (e.g., GDPR, CCPA). Clearly document these measures in the application listing.
D) Thoroughly test the application installation and upgrade process in a separate Snowflake account (ideally one that mimics a typical consumer environment) to identify and resolve any potential issues.
E) The listing should include a well-defined support strategy, outlining how you will handle customer inquiries, bug reports, and feature requests. Provide contact information and estimated response times.
