Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native App that allows consumers to configure certain parameters through a setup page. You want to persist these configurations securely. What is the recommended approach to store and retrieve consumer-specific configuration data within a Snowflake Native App?

A) Store the configuration data in a consumer-specific stage created during app installation.
B) Store the configuration data as environment variables within the application package.
C) Utilize the 'APPLICATION_SETTINGS' object to store and retrieve configuration parameters. Access these settings within your application logic.
D) Store the configuration data in a secured view provided by the provider and accessible to the consumer.
E) Create a dedicated configuration table within the consumer's Snowflake account using the setup script and use secure UDFs to access it.

2. Consider the following Python code snippet used within a Streamlit application deployed as a Snowflake Native App:

A) The code requires using the 'snowflake.snowpark' library instead of for optimized performance within native apps.
B) The code will fail with a privilege error if the 'app_public' role does not have OWNERSHIP of the table 'my_table' .
C) The code will execute without any privilege errors, assuming the necessary database and schema privileges are granted to the 'app_public' role.
D) The code will execute successfully, assuming that Smy_table' exists, and the 'app_public' role has at least SELECT privilege on 'my_table' and USAGE privilege on the schema containing 'my_table' .
E) The code will fail because the Snowflake Connector for Python requires explicit connection parameters to be defined even within a Native App context.

3. You are packaging a Snowflake Native Application for listing on the Marketplace. You have developed a setup script (setup.sql) that creates necessary tables and stored procedures within the application container. During the security scan, you receive warnings related to 'Excessive Privileges Granted'. Review the following snippet from your setup.sql script:

What specific change(s) to the setup script would BEST address the 'Excessive Privileges Granted' warning while ensuring the application functions correctly after installation?

A) Within the procedure, use the 'SECURITY INVOKER clause on the 'CREATE TABLE statement to ensure that the table is created with the end-user's privileges instead of the application owner's privileges.
B) Modify the procedure to run with caller's rights (EXECUTE AS CALLER) and grant SELECT on 'app_data' directly to the end-user's role instead of the application role.
C) Change the GRANT statement to 'GRANT SELECT ON TABLE app_data TO APPLICATION ROLE app_public WITH GRANT OPTION'.
D) Modify the procedure to use an invoker's rights approach (EXECUTE AS OWNER) and limit the SELECT privilege on sapp_data' to only the specific columns required by the application.
E) Revoke the EXECUTE privilege on the 'init_app' procedure from the 'app_admin' role after the application is installed.

4. You are developing a Snowflake Native Application and wish to publish an application package to an external staging location (e.g., AWS S3). You have already created the application package in Snowflake. What are the necessary steps and considerations to ensure the application package is securely and correctly deployed to the external stage, making it accessible to consumers?

A) Grant the SNOWFLAKE DEPLOYMENT application role the CREATE STAGE privilege on the external stage. Then, use the CREATE APPLICATION PACKAGE command with the EXTERNAL STAGE parameter pointing to the external stage location.
B) Use the PUT command to directly upload the application package files to the external stage. Then, create an APPLICATION using the CREATE APPLICATION command, referencing the uploaded files in the stage using the EXTERNAL_STAGE parameter.
C) Create an IAM role in AWS with appropriate permissions to access the S3 bucket. Create a Snowflake integration object referencing the IAM role. Use the CREATE APPLICATION PACKAGE command with the EXTERNAL STAGE parameter pointing to the Snowflake integration object.
D) Create an APPLICATION PACKAGE, then grant CREATE APPLICATION privilege on the package to SNOWFLAKE DEPLOYMENT role and use the SYSTEM$GENERATE_SCIM_ACCESS_TOKEN function to create credentials. Use these credentials to upload the application package files to the external stage.
E) Grant the ACCOUNTADMIN role to the SNOWFLAKE DEPLOYMENT application role and use the TOKEN function to create credentials. Use these credentials to upload the application package files to the external stage.

5. You are packaging a Snowflake Native App that includes a Streamlit application. You need to define specific permissions for the application to access data in the consumer's account. Specifically, the application needs to read from a table named in the schema within the consumer's database 'consumer_db'. Which of the following steps are required to correctly grant these privileges during the application installation process?

A) In your manifest file ('manifest.yml'), declare a 'privileges' section specifying 'SELECT' privilege on 'consumer_db.consumer_schema.consumer_data' for the app_role' .
B) The consumer must manually grant the 'SELECT privilege on 'consumer_db.consumer_schema.consumer_data' to the application's install-time role after the application is installed. No action is needed within the application package.
C) Use the 'snowflake.permissionss module within your Streamlit application to dynamically request the 'SELECT privilege on 'consumer_db.consumer_schema.consumer_data' when the application starts. Display an error message if the privilege is not granted.
D) In your setup script ('setup.sql'), execute 'GRANT SELECT ON TABLE consumer_db.consumer_schema.consumer_data TO APPLICATION ROLE app_role;' where 'app_role' is the application role defined in your application package.
E) Create a secure view in the consumer's account that selects from and grant 'SELECT on the secure view to the application role. This requires coordination with the consumer.
