Snowflake SnowPro Specialty - Native Apps NAS-C01 Prüfungsfragen mit Lösungen (Q329-Q334):

329. Frage
Consider the following setup script snippet for a Snowflake Native Application:

What is the primary purpose of the 'WHERE NOT EXISTS' clause in the 'INSERT' statement within this setup script?

A. To prevent duplicate rows with the same 'param_name' from being inserted into the 'app_data.configuration' table during subsequent installations or upgrades of the application.
B. To handle potential errors that may occur if the 'api_endpoint' parameter is already defined in the consumer's account.
C. To guarantee that the 'app_data.configuration' table always contains the latest version of the 'api_endpoint' parameter, overwriting any existing value.
D. To optimize the performance of the 'INSERT statement by avoiding unnecessary insertions when the configuration parameter already exists.
E. To ensure that the 'INSERT statement only executes if the table is empty.

Antwort: A

Begründung:
Option B is correct. The 'WHERE NOT EXISTS clause prevents duplicate entries for the 'api_endpoint' parameter. The setup script might run multiple times during application installations or upgrades, and without this clause, it would insert duplicate rows. Option A is incorrect, as the clause doesn't check if the entire table is empty. Option C is true to some extent, performance is one of the reasons but not the primary reason. Option D, The consumer account has no role to play here. Option E is wrong because it will do opposite as intended.

330. Frage
Consider the following Java UDF code snippet intended for use in a Snowflake Native Application. The UDF is designed to retrieve data from an external REST API. The code throws a 'java.net.SocketTimeoutException' intermittently when the API takes longer than expected to respond. How can you best handle this exception within the UDF to provide a more informative error message to the consumer and prevent the entire application from failing?

Antwort: E

Begründung:
Option C is the best approach. Throwing a 'SnowflakeSQLException' allows you to provide a structured error message to the consumer with a custom error code CAPI_TIMEOUT) and a user-friendly message. It also includes the original exception for debugging purposes. Option A throws a generic 'RuntimeException' which is not specific to Snowflake and doesn't provide a clear error code. Option B only prints the error to standard error, which may not be captured or easily accessible within Snowflake. Option D returns a string which may not be the expected return type of the UDF and doesn't provide a structured error. Option E only logs the exception to an external service but the UDF needs to handle the error and return the correct snowflake error.

331. Frage
You are developing a Snowflake Native App that provides data enrichment services to consumer accounts. The app requires access to both a secure internal API (accessible only within your provider account) and the consumer's data warehouse. Which of the following components and configurations are necessary to facilitate this access while adhering to Snowflake's security best practices?

A. A Java UDF defined in the application package uses JDBC connection to access a secure internal API endpoint. The consumer grants USAGE privilege to the application on their schemas.
B. A Python UDF defined in the application package that connects to the secure internal API using a secured API integration with allowed egress network policy that only allows connections from the app's deployment region. The consumer shares their database with the provider account through a data sharing arrangement.
C. A UDF (User-Defined Function) defined in the application package that invokes the secure internal API using a secured API integration, and grants OWNERSHIP on it to the APPLICATION role. The consumer grants USAGE on their database to the application role.
D. A Snowpark function that leverages the SNOWFLAKCORE.AUTHZ.PASS PRIVILEGES() function with the application role executing the code. The app requires the consumer to create a shared secret to access their API.
E. A Stored Procedure defined in the application package that invokes the secure internal API via network rule with outbound traffic allowed only for the app, and utilizes a reader account to securely query the consumer s data with the use of SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES().

Antwort: C

Begründung:
Option A is the most secure and correct approach. A UDF allows for encapsulated logic, a secured API integration handles authentication and authorization to the internal API, application role owns the function, and the consumer grants USAGE to the application, limiting access. Option B is less secure, reader account and SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES() are not required. Option C is flawed as data sharing is not the recommended way for native app to consume customer data. Option D - Java UDFs with JDBC is not best practice, not supported, not secure. Option E - shared secret and SNOWFLAKE.CORE.AUTHZ.PASS PRIVILEGES() are not the right approach.

332. Frage
A provider is developing a Snowflake Native App and utilizes event sharing to communicate state changes to consumers. After initial installation, a consumer reports not receiving any event notifications. The provider has verified the event table is populated correctly. Which of the following are the MOST likely reasons for this issue and how can the provider troubleshoot them?

A. The event table function is not correctly filtering events based on the consumer's application instance I Review the function logic to ensure proper filtering using APP_INSTANCE_ID().
B. The consumer's event table function does not have the correct security invoker privileges. Grant EXECUTE TASK on the event table function to the consumer role.
C. The consumer has not refreshed their application instance metadata. Ask the consumer to execute SYSTEM$REFRESH_EXTERNAL_FUNCTIONS() in the application database.
D. The consumer has not explicitly granted the necessary privileges on the event table function to the role used by the app. Instruct the consumer to grant USAGE on the event table function to the app role.
E. Event sharing is inherently unreliable and Snowflake does not guarantee event delivery. The provider should implement alternative polling mechanisms.

Antwort: A,D

Begründung:
B and D are the most likely reasons. B: The consumer needs to grant USAGE on the event table function to the application role. D: The event table function must correctly filter events using APP INSTANCE_ID() to ensure the consumer only receives events related to their instance. A is incorrect because the consumer (not provider) needs to grant usage. C is incorrect as SYSTEM$REFRESH EXTERNAL FUNCTIONS() is not the correct procedure in this context. E is wrong. Snowflake guarantees event delivery, assuming correct setup.

333. Frage
A data provider wants to distribute a Snowflake Native Application that includes a secure view 'PROVIDER DB.PUBLIC.SALES SUMMARY' which aggregates sales dat a. They want to allow consumers of the application to query this view, but prevent them from accessing the underlying base tables. Which minimum set of privileges must be granted on the 'SALES SUMMARY view to enable this, assuming the application role is 'APP ROLE and the installing account doesn't want to use 'imported privileges' ?

A. GRANT ALL PRIVILEGES ON VIEW PROVIDER DB.PUBLISALES SUMMARY TO ROLE APP ROLE;
B. GRANT REFERENCES ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;
C. GRANT USAGE ON DATABASE PROVIDER DB TO ROLE APP ROLE; GRANT USAGE ON SCHEMA PROVIDER DPUBLIC TO ROLE APP ROLE; GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;
D. GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO SHARE WITH APP ROLE;
E. GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;

Antwort: C

Begründung:
The consumer needs 'USAGE' privilege on the database and schema containing the view to access it. The 'SELECT' privilege on the view itself is required to query it. 'GRANT ALL PRIVILEGES' is excessive. 'GRANT ... TO SHARE is not a valid syntax. REFERENCES is for foreign keys.
