問題 #26
You are developing a Snowflake Native Application using Python that processes financial transactions. The application relies on external stages for loading transaction dat a. After deploying the application to a consumer account, you observe that the application fails to load data from the stage, resulting in an 'Invalid stage name' error in the consumer's logs. Assume the stage was created and shared correctly. Which of the following steps would BEST help you diagnose the problem and ensure the application works as expected?

A. Verify that the application manifest includes the correct stage definition with the 'privileges' parameter set to 'USAGE on the stage object. Also, within your Python code, use the 'snowflake.connector' to explicitly grant USAGE privilege from the application role to the stage.
B. Check the application's deployed version details in the consumer account's Snowflake UI to confirm the 'stage_name' parameter within the application manifest is defined correctly, and then within the Python code, make sure to utilize a fully qualified name when referring to the stage. Use Snowflake logging to write stage information to the event table.
C. Redeploy the application with the 'REPLACE' flag to automatically update the stage definition on the consumer side, and confirm that the application has sufficient privileges to access the storage integration associated with the stage. In Python, trap any 'Invalid stage name' exceptions and retry after a short delay.
D. Ensure the stage definition in the 'manifest.yml' file uses the fully qualified name of the stage (database.schema.stage_name), and verify that the consumer has imported the stage's database and schema into their environment. In Python, use the 'DESC STAGE command via a Snowflake connector to confirm existence and permissions.
E. Review the stage properties in both the provider and consumer accounts to ensure the storage integration is correctly configured and accessible from both sides. In the Python code, use the USE ROLE command to explicitly switch to the application's role before accessing the stage.

答案：B

解題說明：
The BEST approach is to verify the stage definition in the 'manifest.ymr and ensure its deployed version details in the consumer account. Using fully qualified names in both the manifest and Python code is essential for the consumer to correctly resolve the stage. Correctly utilize Snowflake logging by writing stage information to the event table. This ensures the application can properly access the stage within the consumer's environment and provides debugging information if issues persist. Incorrect assumptions might lead to focusing on permissions when the fundamental issue is name resolution. Other options suggest using a 'snowflake.connector' to explicitly grant USAGE privilege from the application role to the stage or to utilize a fully qualified name when referring to the stage which will not solve the issue.

問題 #27
You are developing a Snowflake Native Application that requires maintaining multiple live versions for different customer segments. Some customers need to stay on an older version for compatibility reasons, while new customers should use the latest version. How can you best manage these different versions using Snowflake Native App features?

A. By leveraging the 'APPLICATION ROLE to control access to different versions using conditional logic within the application code.
B. By creating separate Snowflake accounts for each customer segment, each with a different version of the application installed.
C. By using streams and tasks to replicate data and logic between different versions of the application, ensuring data consistency.
D. By implementing a custom versioning system within the application's stored procedures and functions, relying on consumer-provided parameters to determine which version of the logic to execute.
E. By creating separate application packages for each version and managing them independently, allowing consumers to choose which version to install. The 'APPLICATION ROLE is used to define application-level access.

答案：E

解題說明：
The correct answer is (C). Snowflake Native Apps allow you to create separate application packages for each version. Consumers can then choose the version that best suits their needs. Using the 'APPLICATION ROLE allows for controlling access to different resources within the application, ensuring proper data governance and security. Options A, D, and E are less efficient or not directly supported by the Snowflake Native App framework. Option B is partially correct that you can leverage application role but version control is through separate application packages.

問題 #28
A Snowflake Native App provider wants to implement row-level security (RLS) in an event table to ensure that consumers only receive events pertaining to their specific organization, even if they have been granted USAGE on the event table function. How can this be achieved?

A. Create a view on top of the event table that includes a WHERE clause filtering by APP INSTANCE ID() and grant access to the view instead of the base table.
B. Row-level security cannot be enforced on event tables shared through Snowflake Native Apps due to security limitations.
C. Implement a custom stored procedure that acts as a proxy for accessing the event table, filtering data based on the consumer's user ID.
D. Create a row access policy that filters rows in the event table based on the APP_INSTANCE_ID() function, ensuring each consumer only sees events related to their application instance.
E. Create a masking policy that filters rows in the event table based on the CURRENT_ACCOUNT() function to match the consumer's account ID.

答案：D

解題說明：
B is the most appropriate answer. Row access policies can leverage APP_INSTANCE_ID() within the Snowflake Native App environment to filter data based on the application instance, achieving the desired row-level security. A is incorrect because CURRENT_ACCOUNT() would not distinguish between different application instances within the same account. C is incorrect as it is more complex than using row access policy directly and more difficult to maintain. D is similar to B but less secure than the row access policy. E is incorrect, RLS can be enforced.

問題 #29
A Snowflake Native App provider has implemented an Event Table to capture application logs. They observe a significant performance degradation in their application queries when the Event Table grows beyond a certain size. Which of the following strategies can be implemented to mitigate the performance issue, assuming that frequent querying of the last 7 days of data is common? Select ONLY ONE answer.

A. Create a materialized view on top of the Event Table that filters for events within the last 7 days.
B. Disable automatic clustering on the Event Table.
C. Increase the warehouse size used for querying the Event Table.
D. Partition the Event Table by date, using the ' INSTALLATION_TIMESTAMP' column.
E. Implement a stored procedure that manually copies the last 7 days of data to a separate, smaller table.

答案：A

解題說明：
Option B, creating a materialized view that filters for the last 7 days of data, is the MOST effective solution. Materialized views pre- compute and store the results of the query, so subsequent queries against the view are significantly faster. Increasing the warehouse size (Option A) might provide some improvement but does not address the fundamental issue of scanning the entire table. Partitioning (Option C) is not supported in Snowflake. Implementing a stored procedure (Option D) adds complexity and overhead. Disabling automatic clustering (Option E) will degrade performance.

問題 #30
A software company, 'Datalnsights', is developing a Snowflake Native Application that requires restricted access to a source data table in the consumer's account. Datalnsights wants to ensure that only the application can access the data, and the consumer cannot directly query it. What is the MOST secure and recommended approach Datalnsights should use within their application package to grant access?

A. Creating a secure view on top of the source data table and granting 'SELECT privilege to the application role on the view.
B. Exposing the table directly through the application's setup script using 'GRANT SELECT ON TABLE TO APPLICATION ROLE app_role' .
C. Granting 'SELECT privilege directly on the source data table to the application role.
D. Granting the ' USAGE privilege on the database and schema containing the source data table directly to the application role.
E. Using a secure UDF within the application to access the source data table, ensuring data masking and redaction, with only the UDF being granted SELECT privileges on the table.

答案：E

解題說明：
Using a secure UDF is the recommended approach. By encapsulating the data access within a secure UDF, you can control precisely how data is accessed and potentially mask sensitive information. Options A, B and E grants direct access which contradicts the requirement for data restriction. While a secure view (C) adds a layer of indirection, a UDF provides greater flexibility and control over the data access logic and potential redaction.
