Snowflake SnowPro Specialty - Native Apps Sample Questions (Q328-Q333):

NEW QUESTION # 328
You're developing a Snowflake Native App that includes a function, , which retrieves sensitive customer dat a. You want to ensure that this data is only accessible by authorized roles within the consumer's account, even after the application is installed. Which of the following strategies are appropriate for securing the application's data and function access? (Choose two)

A. Use a secure UDF to encapsulate the data retrieval logic, preventing direct access to the underlying tables.
B. Grant the 'EXECUTE privilege on the function to the 'application role'.
C. Rely solely on the consumer's account administrator to manage access to the function and data after installation.
D. Implement a masking policy on the underlying customer data table that restricts access based on the current role.
E. Grant the 'EXECUTE privilege on the function to specific, consumer-defined roles within the consumer's account via the provider's setup script.

Answer: D,E

Explanation:
Implementing a masking policy (Option A) directly on the underlying data table ensures that data is masked or restricted based on the user's role, regardless of how the data is accessed. Granting 'EXECUTE to consumer-defined roles (Option C) allows the provider to explicitly control which roles in the consumer's account have access to the function. Option B is incorrect as giving Execute permission to application role won't restrict access within consumer account. Option D can enhance security, it requires role base access control to be truly useful as the UDF will still need explicit role definitions of user access. Option E is insufficient; the provider needs to actively participate in securing the data through mechanisms like masking policies and role-based access control via grants in the setup script.

NEW QUESTION # 329
A data analytics company, 'Data Insights Pro', is developing a Snowflake Native App that visualizes customer behavior dat a. The app needs to read data from a secure customer table provided by the consumer and write aggregate reports back to a separate consumer- owned table for compliance. The customer table contains sensitive PII. Which of the following combinations of application privileges and app capabilities are NECESSARY and SUFFICIENT to achieve this securely, ensuring minimal access is granted?

A. APPLICATION role WITH OWNERSHIP on the REPORT_TABLE, APPLICATION role WITH SELECT privilege on the CUSTOMER_TABLE through a SECURE VIEW, and the 'network access' capability.
B. APPLICATION role WITH OWNERSHIP on the REPORT TABLE, APPLICATION role WITH SELECT privilege on the CUSTOMER TABLE, and the 'external network access' capability.
C. APPLICATION role WITH INSERT privilege on the REPORT TABLE, APPLICATION role WITH SELECT privilege on the CUSTOMER TABLE, and the 'network access' capability.
D. APPLICATION role WITH INSERT privilege on the REPORT TABLE, APPLICATION role WITH SELECT privilege on the CUSTOMER TABLE through a SECURE VIEW, and no additional capabilities.
E. APPLICATION role WITH INSERT privilege on the REPORT_TABLE, APPLICATION role WITH SELECT privilege on the CUSTOMER_TABLE through a SECURE VIEW, and the 'external network access' capability.

Answer: D

Explanation:
The app needs to write to REPORT_TABLE (requires INSERT, not OWNERSHIP as ownership implies broader privileges than required), read from CUSTOMER TABLE (requires SELECT, and using a secure view is the best practice to minimize PII exposure), and does not require network access since everything happens within Snowflake's environment. No external network access is required as no data is transmitted externally.

NEW QUESTION # 330
You are developing a Snowflake Native App that leverages shared data from the consumer's account. The app needs to dynamically determine the existence of a specific table (e.g., 'CUSTOMER DATA) in the consumer's shared database before attempting to query it. Which of the following SQL commands or approaches within the application package provides the MOST reliable way to programmatically check for the existence of the table?

A. Attempt to grant SELECT privilege on the table and check if an error occurs
B. Use the 'DESCRIBE TABLE CUSTOMER_DATX command within a 'TRY...CATCH' block and handle the exception if the table does not exist.
C. Use the ' SHOW TABLES LIKE 'CUSTOMER_DATA" command and check if any rows are returned.
D. Execute a 'SELECT 1 FROM CUSTOMER_DATA LIMIT 1' query within a 'TRY...CATCH' block and handle the exception if the table does not exist.
E. Use the 'INFORMATION SCHEMA.TABLES' view and query it to check if a table with the name 'CUSTOMER DATA' exists in the shared database.

Answer: E

Explanation:
Option C (Use the 'INFORMATION SCHEMATABLES view) is the most reliable and recommended approach. The INFORMATION_SCHEMR provides metadata about database objects, and querying it to check for the existence of a table is a standard and efficient practice. Option A ('SHOW TABLES) might be affected by the session context or user's privileges. Options B and D (using 'TRY...CATCH' blocks) rely on exception handling, which can be less efficient and less readable. Also, consuming exceptions can be more expensive than directly querying system views. Option E is inefficient since it requires an attempt to change a permission.

NEW QUESTION # 331
You are developing a Snowflake Native Application that requires configurable settings for different customer environments. These settings include API endpoint URLs, authentication keys, and resource limits. You want to allow the consumer to configure these parameters during installation. Which of the following options are valid methods for securely and effectively handling these configurations in a Snowflake Native App?

A. Create a dedicated Snowflake stage for configuration files. Consumers can upload their configuration files to this stage during installation, and the application reads these files upon startup.
B. Implement configuration tables within the application's shared data, secured by appropriate grants and roles, and provide a setup script that the consumer can execute to populate these tables with their desired values. Use secure views to access this configuration data.
C. Store configuration parameters directly in the application code as environment variables. This simplifies initial setup and reduces dependencies on external services.
D. Utilize the 'SNOWFLAKE.ACCOUNT_USAGE schema to store configuration values. This ensures high availability and scalability, as it leverages Snowflake's managed infrastructure.
E. Expose configuration parameters as secure UDFs (User-Defined Functions) that the consumer can modify after installation. This allows for dynamic adjustments without direct access to internal application logic.

Answer: B

Explanation:
Option C is the most suitable and recommended approach. Storing configuration parameters in secure configuration tables within the application's shared data, secured by appropriate grants and roles, allows the consumer to set configurations without compromising the application's code or security. Option A is not ideal because secure UDFs are meant for other purposes. Option B is incorrect because 'SNOWFLAKE.ACCOUNT_USAGE schema is read-only. Option D is a security risk. Option E is less secure and less manageable.

NEW QUESTION # 332
A Native Application is being developed that requires access to the consumer's Snowflake account for billing purposes. The application needs to record the query history of the consumer's account to estimate resource usage. Which is the MOST secure and efficient method for the Native App to access this data, minimizing the permissions granted to the app and considering the governance aspects?

A. Grant the ' USAGE privilege on the 'SNOWFLAKE' database to the Native App's service account, allowing it to query all tables and views in that database.
B. Grant the ' MONITOR USAGE' privilege to the Native App's service account, allowing it to query the view.
C. Create a stored procedure within the Native App that executes as the 'OWNER and queries the view. The stored procedure is granted to the Native App's service account with 'EXECUTE privileges.
D. Grant the 'ACCOUNTADMIN' role to the Native App's service account. This provides full access to the account's query history.
E. Use the 'READ SESSION' privilege to allow the application to read the current session context and infer the resource usage from it.

Answer: C

Explanation:
Granting 'ACCOUNTADMIN' is highly insecure and violates the principle of least privilege. 'MONITOR USAGE is not sufficient to query 'QUERY_HISTORY. 'READ SESSION' provides limited contextual information and wouldn't allow retrieval of full query history. Granting USAGE on the 'SNOWFLAKE database is too broad and exposes more data than necessary. A stored procedure executing as the 'OWNER allows controlled access to the query history while minimizing the permissions granted directly to the application's service account.
