Snowflake SnowPro Specialty - Native Apps Sample Questions (Q342-Q347):

NEW QUESTION # 342
You are developing a Snowflake Native App that needs to access a secured external API to enrich customer dat a. The API requires an OAuth 2.0 token stored securely. Which of the following approaches would you use within the application manifest and Snowflake objects to securely store and access this token, minimizing exposure and adhering to best practices?

A. Use Snowflake's SECRET object type to securely store the OAuth 2.0 token. Reference the SECRET object within the application using PARAMETERS in the manifest and utilize function in application code to retrieve it at runtime.
B. Store the OAuth 2.0 token as a masked comment within the application's SQL code. This will provide sufficient obfuscation.
C. Store the OAuth 2.0 token as a cleartext secret in a Snowflake stage and access it using external functions.
D. Hardcode the OAuth 2.0 token within the application's stored procedures. This ensures the token is readily available.
E. Store the OAuth 2.0 token directly in the application's manifest file as a PARAMETER. This simplifies access within the application code.

Answer: A

Explanation:
Storing secrets like OAuth tokens directly in the manifest or hardcoding them is a significant security risk. Using Snowflake SECRET objects is the recommended approach for securely managing sensitive information. The 'SYSTEM$GET SECRET function provides a secure way to retrieve the secret at runtime without exposing it in the code or manifest. Snowflake stages shouldn't be used to store secrets in clear text.

NEW QUESTION # 343
You are developing a Snowflake Native Application designed to be deployed by various consumers from the Snowflake Marketplace. The application interacts with user-provided data through secure UDFs and external functions. To ensure minimal impact and prevent unintended data access, how should you configure the application's security context and privileges when creating the application package?

A. Create a separate application role with minimal privileges, and grant only 'USAGES on the database and 'EXECUTE' on the relevant functions to that role. Use 'CALL to grant USAGE on the share.
B. Use the 'CALL APPLICATION.API GRANT PRIVILEGE command, and grant only the 'USAGE privilege on the shared database containing consumer data, along with the ' EXECUTE privilege on the UDFs and external functions.
C. Grant OWNERSHIP privilege on all schemas and tables to the application's service account.
D. Define roles within the application and grant 'USAGE' on all schemas and 'SELECT on all tables to these roles.
E. Grant 'ALL PRIVILEGES on the database containing consumer data to the application role.

Answer: A

Explanation:
The best practice for securing Native Applications is to follow the principle of least privilege. Granting 'OWNERSHIP' or 'ALL PRIVILEGES' (A, D) is far too permissive and poses a significant security risk. While creating roles within the application (C) offers some control, it doesn't leverage the explicit privilege granting mechanism designed for Native Apps. Option B is partially correct but incomplete. Option E is the most secure and correct approach. It uses a dedicated application role with minimal required privileges CUSAGE on database, 'EXECUTE on UDFs/external functions) and 'CALL to grant 'USAGE' on the data share provided by the consumer, ensuring that the application can only access the explicitly shared data and execute the intended functions.

NEW QUESTION # 344
You're developing a Snowpark Container Services application. Your 'service.yaml' file defines a service named 'data_processor'. You want to create a service endpoint, 'ingest_endpoint' , that is secured and accessible only by authorized consumers of your Snowflake Native Application. Select the TWO SQL statements that, when used together, will correctly create and bind the service endpoint, ensuring proper OAuth authentication and authorization.

A. BIND SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = OAUTH TO APPLICATION PACKAGE;
B. ALTER SERVICE data_processor ADD ENDPOINT ingest_endpoint WITH AUTHENTICATION TYPE = OAUTH;
C. BIND SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = NONE TO APPLICATION PACKAGE;
D. CREATE OR REPLACE SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = SNOWFLAKE_JWT;
E. CREATE SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = OAUTH;

Answer: A,E

Explanation:
'CREATE SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = OAUTH;' creates the actual service endpoint. 'BIND SERVICE ENDPOINT ingest_endpoint FOR SERVICE data_processor WITH AUTHENTICATION TYPE = OAUTH TO APPLICATION PACKAGE;' links the endpoint to the application package and enables OAuth. The 'Bind' command makes sure to use the proper service with Authentication. Without Authentication, application can be compromised easily. Thus, option B and D are invalid here.

NEW QUESTION # 345
You are developing a Snowflake Native Application that provides data enrichment services. You want to offer tiered pricing based on the number of API calls made by consumers. Which of the following is the most effective approach to implement usage-based billing and track API call consumption within your application?

A. Leverage Snowflake's built-in metering framework using and 'SYSTEM$METER STAGE_STORAGE BYTES' to indirectly estimate API calls.
B. Implement a UDF within the application that increments a counter in a shared table each time an API endpoint is called. Query this table to determine usage.
C. Utilize Snowflake's events table to capture API call events based on function executions, enabling precise tracking and reporting of API usage for each consumer.
D. Implement a custom logging mechanism within the application to track API calls and store the logs in a separate Snowflake database, accessible only to the provider. Use scheduled tasks to analyze these logs and generate billing data.
E. Use Snowflake's resource monitors to limit the compute resources available to consumers based on their chosen tier.

Answer: B

Explanation:
Option A is the most effective as it directly tracks API calls within the application. Resource monitors (B) only control compute costs, not API usage. System$METER functions (C) track storage, notAPl calls. Custom logs (D) introduce complexity and security concerns. Snowflake's events table is a good general approach (E), but requires enabling detailed logging, which has performance implications and might not be available in all accounts. A shared table with a UDF provides the most direct and controllable way to meter usage.

NEW QUESTION # 346
A Snowflake Native Application provider is troubleshooting an issue reported by a consumer during testing. The application uses a UDF to process dat a. The error message suggests the UDF is failing due to insufficient permissions to access a secure view owned by the application. The UDF and view are defined as follows:

Which of the following steps are MOST likely to resolve the permission issue without compromising security principles?

A. Grant the ' SELECT privilege on 'app_db.app_schema.secure_view' to the consumer's account.
B. Grant the ' SELECT' privilege directly on 'app_db.app_schema.internal_table' to the 'app_role' .
C. Ensure the UDF is declared as 'SECURE and the view is also declared as 'SECURES. No explicit grants are required.
D. Grant the 'IMPORTED PRIVILEGES privilege on the application database to the application's 'app_role' .
E. No further action is required. Secure views and UDFs automatically inherit the necessary privileges within the application container.

Answer: C

Explanation:
Option B is the correct answer. When both the UDF and the view are declared as 'SECURE, Snowflake handles the privilege inheritance automatically within the application container. No explicit grants are required, and the application maintains its security posture. Option A is incorrect because granting access directly to internal tables violates the principle of least privilege and exposes underlying data structures. Option C is incorrect as the view is for internal use, not direct access. Option D is incorrect. 'IMPORTED PRIVILEGES are used for sharing data outside of the application container, not for access within the application. Option E is partially correct, but incomplete. Both need to be declared as 'SECURE.
