Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q234-Q239):

質問 # 234
You are developing a Snowflake Native App that processes data in the consumer's account and presents the results in a dashboard. You need to ensure that the dashboard automatically updates when the underlying data changes. Which of the following approaches, or combination of approaches, would be MOST effective in achieving this real-time or near real-time data refresh for the dashboard?
Choose TWO.

A. Rely solely on the consumer's existing data pipelines to update the data used by the dashboard.
B. Schedule a Snowflake Task within the application package to refresh the data used by the dashboard every minute.
C. Use Snowflake Streams and Tasks to incrementally update the dashboard's underlying data based on changes in the source tables.
D. Implement a mechanism where the consumer's application triggers a refresh of the dashboard's data through a stored procedure whenever they detect changes in their data.
E. Implement a serverless function using Snowflake's Snowpark Container Services to periodically query the consumer's data and update the dashboard within the Native App environment.

正解：C、D

解説：
Streams and Tasks are designed for incremental data processing and are well-suited for automatically updating data in response to changes. Allowing the customer to trigger an update is useful, but it doesn't provide auto update. A task can be used, however Streams and Tasks should be used. Depending on the application architecture Container Services might be used to keep the dashboards updated.

質問 # 235
You are developing a Snowflake Native App that needs to perform asynchronous tasks in the consumer's account. Which of the following approaches is the MOST suitable and secure way to achieve this, ensuring minimal impact on the consumer's resources and maintaining data integrity?

A. Implement a Snowpark UDF that starts a new thread to handle the asynchronous task within the consumer's compute environment.
B. Utilize an external message queue (e.g., AWS SQS, Azure Queue Storage) to offload asynchronous tasks, requiring the consumer to configure network policies to allow egress traffic to the queue.
C. Implement a scheduled stored procedure that polls for new tasks every minute and processes them, potentially consuming significant compute resources in the consumer's account. The stored procedure is deployed in the consumer's account using CREATE APPLICATION.
D. Create a Snowflake Task that is executed within the consumer's account, triggered by events within the application, and configured to run on a Snowflake-managed compute pool.
E. The Native App can create task and warehouse in the consumer account to execute the code using CREATE APPLICATION command. The application uses SNOWFLAKE.CORE.AUTHZ.PASS PRIVILEGES() to execute these tasks.

正解：D

解説：
Using Snowflake Tasks (Option A) is the recommended approach for asynchronous task execution within a Snowflake Native App. The task is managed within the consumer's account but still deployed as part of app package, avoiding the need for external dependencies or extensive consumer configuration. Option B introduces complexity and security concerns with external message queues. Option C can be resource-intensive and inefficient. Option D is incorrect as apps are not allowed to create warehouses. Option E is not supported, UDFs do not run in separate threads.

質問 # 236
A Snowflake Native Application developer is debugging a privilege issue in the consumer's account. They suspect that a specific application role, 'app_admin' , does not have the necessary privileges to execute a stored procedure 'calculate_summary' within the application. Which of the following SQL statements will BEST help the developer diagnose the problem by listing the privileges granted to the 'app_admin' role? (Assume exists within the application.)

A. SHOW GRANTS OF APPLICATION ROLE app_admin;
B. SHOW GRANTS ON STORED PROCEDURE calculate_summary TO APPLICATION ROLE app_admin;
C. SELECT FROM WHERE grantee_name = 'APP_ADMIN';
D. SHOW GRANTS TO ROLE app_admin;
E. SHOW GRANTS TO APPLICATION app_admin;

正解：A

解説：
'SHOW GRANTS OF APPLICATION ROLE is the specific syntax used to view the privileges granted to an application role within a Snowflake Native Application. "SHOW GRANTS TO ROLE app_admin' would look for a regular role named app_admin, not an application role. The SNOWFLAKE.ACCOUNT_USAGE views don't know about application roles and can only return data about 'regular' Snowflake roles.

質問 # 237
Consider the following 'manifest.yml' file for a Snowflake Native App:

A. The application will fail to install because no 'privileges' are listed in the manifest file. All applications must declare the necessary privileges.
B. The application will fail to install because the version property is missing. Each version must explicitly be specified in the manifest file.
C. The application version will be automatically assigned by Snowflake during the installation process on the consumer side.
D. The application version will default to '0.0.1'. If the application includes a view, then the view needs access to the user data and must have a privilege declared to allow users to view data from the application.
E. The application version will default to '0.1.0' and the application can be installed successfully by any consumer account.

正解：B

解説：
A valid version is mandatory in 'manifest.yml' to install native apps. When version is missing, the installation will fail.

質問 # 238
You are developing a Snowflake Native Application that uses Streamlit for its user interface. The application needs to access a custom Python module named 'my_module' which resides within your application package. You have correctly packaged the module. However, when running the Streamlit application, you encounter an 'ImportError: No module named What is the most likely reason for this error and how can you resolve it?

A. The Streamlit application is not aware of the application package's Python environment. You need to set the environment variable within the Streamlit application to point to the directory containing 'my_module'.
B. The correct handler is not specified in the 'manifest.ymr file.
C. Streamlit does not support custom Python modules within Snowflake Native Applications. You must use only built-in Python modules or those available through Anaconda.
D. The 'my_module' is not included in the file for your application package. Add it to the 'packages' list in 'setup.py'.
E. The 'my_module' is not located in the correct directory structure within the application package. Ensure it's placed in the 'src' directory (or the directory specified in 'package-name' in 'setup.py') and the directory structure mirrors the package structure required for import.

正解：E

解説：
The most likely reason for the 'ImportError' is that the Python module is not located in the correct directory structure within the application package. When you build your application package, Snowflake expects your Python code to reside in a specific directory structure, typically the 'src' directory (or as configured in 'setup.py'). If the module is not in this structure or the correct package structure is not present, the Streamlit application will not be able to find it during import. Option A is incorrect, setup.py is for installation not direct packaging. Option B setting PYTHONPATH is not supported. Option D is incorrect, Custom Modules are supported by Streamlit. Option E is incorrect, as it has nothing to do with the module location and packaging.
