Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You've built a Snowflake Native Application and are ready to test it in test mode. The application utilizes both internal stages and external stages for data storage. Which of the following statements accurately describe the behavior of stages and data access during test mode installations from the provider's perspective?

A) Data loaded into internal stages during test mode is automatically persisted to the consumer's account upon final installation of the application.
B) External stages, regardless of their access permissions, are inaccessible during test mode installations to prevent unintended data leakage.
C) During test mode, the provider has full access to all data stored in both internal and external stages associated with the application, mimicking the access rights in a production environment.
D) The provider can configure specific external stages to be accessible in test mode by granting appropriate privileges to the application role and explicitly defining these stages in the setup script.
E) Internal stages defined within the application package are accessible to the application code running in test mode. Data placed in these stages before installation is available immediately.

2. You are developing a Snowflake Native Application that includes a TASK which calls a stored procedure. The stored procedure interacts with an external API using an external function. The external function is defined with an API integration. To ensure secure access to the external API, how should the privileges be granted so that the TASK can execute successfully and access the external function within the consumer account?

A) Grant OWNERSHIP on the API integration and EXECUTE TASK privilege on the TASK to the 'app_public' role.
B) Grant USAGE privilege on the API integration and EXECUTE TASK privilege on the TASK to the 'app_public' role.
C) Grant USAGE privilege on the API integration to the 'app_public' role and no specific privilege on the TASK, as task execution is implicitly granted.
D) Grant USAGE privilege on the API integration to the 'application' role and EXECUTE TASK privilege on the TASK to the 'app_public' role.
E) Grant USAGE privilege on the API integration and EXECUTE TASK privilege on the TASK to the 'app_owner' role.

3. You are creating a Snowflake Native App using the Native Apps Framework. Your application needs to perform a task that must execute on a regular schedule (e.g., daily data refresh). Which Snowflake feature(s) can you leverage to achieve this, and what considerations are important when using them within the Native App context?

A) Snowflake Tasks can be used directly within the Native App, but you must ensure the task definition is part of the application package and the task is resumed upon installation in the consumer account. The task must use the APPLICATION role.
B) Snowflake Pipes are the preferred method for scheduled data ingestion within Native Apps, as they are designed for continuous data loading from external sources.
C) You should implement an external scheduler (e.g., AWS Lambda, Azure Functions) that triggers a Snowflake Stored Procedure via the Snowflake API. The Stored Procedure should be owned by the APPLICATION role.
D) Snowflake Streams should be used to track data changes and trigger the refresh process. The Stream must be defined in the application package, and a separate task can be configured to consume the stream data.
E) Use Snowflake Alerts with a cron schedule to trigger a stored procedure owned by the APPLICATION role. The procedure executes any scheduled task.

4. A Snowflake Native App is designed to process data in a consumer's account. The application requires access to multiple shared databases provided by different providers. The application provider configures their application. Snowflake is configured so that the app can see all of these shared databases. Now, to enable the Native App with the privileges it requires, what are the necessary steps to allow the application's role, , to query tables in these shared databases?

A) Grant USAGE on each shared database to the 'app_role' . Additionally, grant 'SELECT privilege on each specific table or view the application needs to access in each shared database to the 'app_role' .
B) Grant 'IMPORTED PRIVILEGES' on each shared database to the 'app_role' . Additionally, grant 'SELECT privilege on each specific table or view the application needs to access in each shared database to the 'app_role' .
C) Only grant 'IMPORTED PRIVILEGES on each shared database to the 'app_role' .
D) Grant 'ALL PRIVILEGES on each shared database to the 'app_role'. This will allow the application to access all objects within the shared databases.
E) No additional steps are required. Once the application is installed, it automatically has access to all shared databases.

5. You are developing a Snowflake Native Application that relies on external functions (UDFs/UDTFs) for data processing. A new version of your application includes significant changes to these external functions, potentially affecting existing consumer data and queries. How should you manage the upgrade process to minimize disruption and ensure data integrity in consumer accounts? Assume consumers rely on your function names in their queries. Which of the following approach is MOST suitable?

A) Use release directives to direct users to an intermediate version that provides a compatibility layer for the external function changes. This layer translates calls to the old function names into calls to the new functions, allowing for a phased transition.
B) Create new versions of the external functions with different names while maintaining the old functions in the new version. Consumers can then migrate to the new functions at their own pace. Use release directives to route new users to new functions.
C) Update the external functions in place with the new logic. Snowflake's versioning will automatically handle any compatibility issues for existing queries.
D) Rename all the external functions in the new version and instruct consumers to update their queries accordingly after the upgrade.
E) Develop wrapper functions in the new version that call the original external functions with the new logic applied. Consumers can then gradually migrate to the wrapper functions without immediately changing their queries.
