Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are managing the release of a new version (v2.0) of your Snowflake Native Application that introduces significant schema changes to shared tables accessed by consumer accounts. To minimize disruption during the upgrade, you want to implement a phased rollout while ensuring backward compatibility for consumers who haven't yet upgraded. Which of the following strategies would allow you to achieve this goal effectively? (Select TWO)

A) Implement API versioning within your application code and provide compatibility layers to handle requests from consumers running older versions.
B) Create views on top of the new schema in v2.0 that emulate the old schema from vl .0. Grant consumers 'USAGE' on these views until they upgrade.
C) Publish v2.0 without any schema changes and rely on consumers to manually migrate their data to new tables after upgrading.
D) Use dynamic SQL within stored procedures to conditionally access either the old or new schema based on the consumer's account ID, identified through a custom configuration table.
E) Create separate versions of the shared tables for vl .0 and v2.0, using views to present a unified interface. Grant consumer 'USAGE on view after upgrading.

2. A data analytics company is developing a Snowflake Native App that allows customers to enrich their existing Snowflake data with external, proprietary datasets. The application requires READ access to customer tables and the ability to store processed results within the application's managed database. Which combination of Snowflake Native App Framework privileges and features is MOST appropriate to achieve this functionality?

A) The application's manifest includes REQUESTED PRIVILEGES = [ 'READ ON DATABASE', 'READ ON TABLE' l. Use stored procedures executing with definer's rights to access customer tables through a secure view, and standard INSERT statements to write to the managed database.
B) The application package grants OWNERSHIP privilege on customer tables to the application. Use standard INSERT statements within stored procedures to write enriched data into the application's managed database.
C) Use an API Integration to securely access the customer's data and a Stored Procedure to write the enriched data into application's stage.
D) The application's manifest includes REQUESTED PRIVILEGES = [ 'READ' l. Use stored procedures executing with definer's rights to access customer tables and external functions to write to the managed database.
E) The application's manifest includes REQUESTED PRIVILEGES = [ 'USAGE ON DATABASE', 'READ ON TABLE' ]. Use stored procedures executing with caller's rights to access customer tables and standard INSERT statements to write to the managed database.

3. You are responsible for managing the pricing plans for your Snowflake Native Application listed on the Marketplace. You want to offer a 'Premium' tier that includes additional features and resources. To achieve this, you need to modify the listing to include this new pricing option. Which of the following steps are NECESSARY and in the CORRECT order to successfully add the 'Premium' tier to your application's listing, ensuring existing customers are not negatively impacted? (Choose two options in their proper order)

A) 1. Test new Pricing in a Sandbox environment with few consumers. 2. Deploy the new version to the consumer accounts.
B) 1. Create a new version of the application package in your provider account with the code changes supporting the 'Premium' features. 2. Update the Marketplace listing with the new version of the application and add the 'Premium' pricing tier with appropriate settings.
C) 1. Update the Marketplace listing by adding the 'Premium' pricing tier with appropriate settings, but without modifying the application package. 2. Inform existing customers that the new pricing tier is available.
D) 1. Update the listing on the Marketplace with the new pricing tier. 2. Ensure backward compatibility for existing customers by implementing logic in the application to detect their current tier and maintain existing functionality.
E) 1. Modify the existing application package in place to include the code changes supporting the 'Premium' features. 2. Update the Marketplace listing with the modified application and add the 'Premium' pricing tier with appropriate settings.

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 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.
C) 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.
D) 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
E) The stored procedure is missing the EXECUTE MANAGED ACCOUNT privilege. Add 'GRANT EXECUTE MANAGED ACCOUNT ON PROCEDURE TO APPLICATION ROLE to the setup script.

5. A Snowflake Native Application, 'Geolnsights', uses an external API to enrich location data provided by consumers. This API requires an API key for authentication. How can you securely manage and access this API key within the Native Application's code, ensuring that it is not directly exposed in the application package or code repository?

A) Use a Snowflake Secret to store the API key and retrieve it within the application's UDF using the 'SYSTEM$GET SECRET function.
B) Store the API key directly in a configuration file within the application package and encrypt the application package during deployment.
C) Pass the API key as a parameter to the UDF from the consumer's environment.
D) Hardcode the API key within the UDF itself after obfuscating it using a basic encoding algorithm (e.g., Base64).
E) Store the API key in an external key management system (e.g., AWS KMS, Azure Key Vault) and retrieve it within the UDF using a custom external function, ensuring the function has appropriate access permissions.
