Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are publishing a Snowflake Native Application to the Marketplace. You've completed initial testing, and the application appears to function as expected. However, the security scan consistently fails with a 'Data Exfiltration' error. The application includes a stored procedure that aggregates data from several tables within the application container and writes the results to an external stage using the 'COPY INTO' command. Review the following code snippet:

Which of the following changes is MOST likely to resolve the 'Data Exfiltration' error during the security scan?

A) Require the consumer to explicitly grant the application usage privilege on a secure external stage controlled by the consumer, and modify the procedure to validate the stage's existence and permissions before exporting data.
B) Remove the 'GRANT EXECUTE privilege on the 'export_data' procedure from the 'app_public' role.
C) Encrypt the data written to the external stage using client-side encryption with a key managed by the application provider.
D) Modify the stored procedure to only export data to a table within the application container instead of an external stage.
E) Implement row-level security policies on the 'aggregated_data' table to restrict access to sensitive rows.

2. You are developing a Snowflake Native Application that leverages a UDF to perform complex data transformations. During provider-side testing in test mode, you encounter an intermittent error within the UDF. Which of the following strategies are MOST effective in debugging this issue within the limitations of test mode, considering you cannot directly access the consumer's Snowflake account or granular execution logs?

A) Simulate the consumer environment as closely as possible on the provider side by creating a separate Snowflake account with similar data volumes and configurations, then install the application in test mode in that account.
B) Implement rigorous input validation within the UDF to catch potential data inconsistencies that might be causing the error. Ensure informative error messages are returned for debugging purposes.
C) Leverage Snowflake's query profiling tools on the provider side against the application's data-sharing objects to identify performance bottlenecks or unexpected behavior within the UDF's execution plan. (Assume data sharing objects are set up for provider side testing)
D) Utilize 'SYSTEM$LOG' within the UDF to output detailed execution information to the application's event table. Analyze these logs after triggering the error in test mode.
E) Use the ALERT' functionality to send notifications to the provider's account whenever the UDF encounters the error, allowing for real-time monitoring of the application's behavior.

3. You are developing a Snowflake Native App that requires specific privileges to access data in the consumer's account. In your manifest file, you want to request these privileges. Which of the following statements best describes the correct way to request these privileges within the 'privileges' section of the manifest file?

A) Use the 'allowed_roles' section in the manifest to list the roles that are allowed to access data in the consumer's account, Snowflake automatically grants necessary privileges to these roles.
B) Specify a list of required privileges under the 'privileges' section, detailing the specific objects (databases, schemas, tables) and actions (SELECT, INSERT, UPDATE) the application needs to perform.
C) Privileges are managed entirely through the application's setup scripts. The manifest file does not play a role in privilege management.
D) You can only request privileges for future grants. Existing object grants are not supported in manifest file.
E) Privileges are automatically granted to the application based on the roles specified in the application code. No explicit declaration is needed in the manifest file.

4. You are developing a Snowflake Native Application that utilizes Streamlit for its user interface. The application needs to access data from a protected table within the provider account. To enhance security, you want to grant specific privileges to the Streamlit application without exposing the underlying table directly. Which of the following steps are necessary to achieve this, ensuring the principle of least privilege?

A) Use an external function (UDF) owned by the application to query the protected table and grant USAGE' privilege on the UDF to the Streamlit application's role.
B) Create a secure view on the protected table and grant 'SELECT privilege on the secure view to the Streamlit application's role.
C) Grant 'SELECT privilege directly on the protected table to the Streamlit application's role.
D) Create a stored procedure with 'EXECUTE AS CALLER which queries the protected table and grant 'USAGE privilege on the procedure to the Streamlit application's role.
E) Create an API integration, implement a service (e.g., AWS Lambda) that queries the data and grant 'USAGE on the API Integration and appropriate permissions on the service to the Streamlit application's role.

5. You are the developer of a Snowflake Native Application. You've created a new version of your application package, v2.0. You want to perform a controlled rollout, first releasing it to a subset of your consumers for testing before making it generally available. Which sequence of steps, leveraging Snowflake's lifecycle management features, would you use to achieve this?

A) 1. Create a new APPLICATION role for beta testers. 2. Grant USAGE privilege on version v2.0 to the beta testers APPLICATION role. 3. Instruct beta testers to manually specify VERSION = 'v2.0' when creating their application instances.
B) 1. Create a new APPLICATION role for beta testers. 2. Grant USAGE privilege on the application package to the beta testers APPLICATION role. 3. Grant USAGE privilege on version v2.0 to the beta testers APPLICATION role. 4. Update the default version of the application package to v2.0.
C) 1. Create a new APPLICATION role for beta testers. 2. Grant USAGE privilege on version v2.0 to the beta testers APPLICATION role. 3. Update the default version of the application package to v2.0.
D) 1. Instruct consumers to use the 'ALTER APPLICATION' command to upgrade to v2.0. 2. Monitor consumer feedback on the upgraded version.
E) 1. Create a dedicated APPLICATION role for the application. 2. Grant OWNERSHIP on the application package to the application's APPLICATION role. 3. Update the default version of the application package to v2.0.
