Snowflake SnowPro Specialty - Native Apps Sample Questions (Q73-Q78):

NEW QUESTION # 73
You are developing a Snowflake Native App that will be listed on the Snowflake Marketplace. The application requires the consumer to grant access to their 'CUSTOMER DATA table. Which of the following statements accurately describes the process and required privileges for accessing the consumer's data?

A. The consumer must explicitly grant the 'SELECT privilege on the 'CUSTOMER_DATR table or a secure view of that table to the application's installation role through an inbound share.
B. The application automatically has full access to all tables in the consumer's account, including 'CUSTOMER_DATA' , once installed.
C. The consumer grants the 'IMPORTED PRIVILEGES privilege on the database containing the 'CUSTOMER_DATX table to the application's installation role,and the application uses the CURRENT ACCOUNT() function to access the data.
D. The application provider defines a secure view within the consumer's account, and the consumer grants the 'SELECT privilege on the 'CUSTOMER_DATX table to the secure view.
E. The consumer must explicitly grant the 'USAGE privilege on the 'CUSTOMER DATA' table to a share created by the application provider during installation.

Answer: A

Explanation:
Snowflake Native Apps access consumer data through an inbound share. The consumer must explicitly grant permissions (typically 'SELECT' on a table or a secure view) to the application's installation role via this share. Automatic access (A) is incorrect for security reasons. USAGE (B) is not sufficient for data access. The provider doesn't directly define objects in the consumer's account (C). 'IMPORTED PRIVILEGES' (D) are used for a slightly different use-case, they do not inherently grant access to a specific table within a database, but rather all objects. It needs to be linked to the database containing the data you intend to share, which is what 'E' does using an inbound share.

NEW QUESTION # 74
You are designing a Snowflake Native Application that involves data sharing with consumers. You want to leverage a custom Python library 'data_transform.py' within your application package to perform specific data transformations on the shared data before it is accessed by consumers. This library contains sensitive logic and should not be directly visible or accessible by the consumer. Which of the following is the MOST secure and appropriate way to package and utilize this 'data_transform.py' library?

A. Store 'data_transform.py' as an internal stage file and read it dynamically into your application's Python code at runtime.
B. Package 'data_transform.py' as a user-defined function (UDF) and grant 'USAGE privilege on the UDF to the consumer's role.
C. Embed the contents of 'data_transform.py' directly within the application's stored procedure code as a multi-line string.
D. Include directly within your application package's source code and call its functions from within your application's procedures. Grant necessary privileges on the procedures to the consumer's role, ensuring to only expose the procedures and never the python source.
E. Publish 'data_transform.py' as a public Python package on Anaconda and have consumers install it in their Snowflake environment.

Answer: D

Explanation:
The most secure and appropriate way to package and utilize the custom library is to include it directly within your application package's source code and call its functions from within your application's procedures. This approach ensures that the library's sensitive logic remains encapsulated within your application and is not directly visible or accessible by the consumer. Only expose stored procedures with defined permissions and never the underlaying source code. Options A, UDFs, can be a way to expose code but also requires direct granting of USAGE which is not ideal. Option C, storing as an internal stage file, adds complexity and does not inherently improve security. Option D exposes code publicly, thus, this is incorrect. Option E can be hard to maintain.

NEW QUESTION # 75
You are developing a Snowflake Native Application that uses a Stored Procedure to orchestrate complex data processing tasks. This stored procedure is defined within the application package. When testing in test mode, which of the following security considerations are paramount to ensure the procedure executes correctly and securely, without unintentionally granting excessive privileges to the consumer?

A. Grant the 'EXECUTE' privilege on the stored procedure to the 'PUBLIC' role during test mode. This simplifies testing but should be revoked before publishing the application.
B. Create a dedicated service user specifically for the application and grant only the necessary privileges to this user. The stored procedure should then execute with the privileges of this service user using the 'EXECUTE AS CALLER clause. This allows granular access control.
C. Define the stored procedure with the 'EXECUTE AS OWNER clause. This ensures the procedure always runs with the privileges of the application owner, regardless of the caller's permissions.
D. Since the application is running in test mode, security is not a major concern. Granting all necessary privileges directly to the application role simplifies testing without compromising the consumer's security.
E. Ensure that any roles granted to the application role also have the necessary privileges to execute the stored procedure, and access the objects it interacts with. The stored procedure must be defined with 'EXECUTE AS CALLER.

Answer: E

Explanation:
Option D is correct because using 'EXECUTE AS CALLER grants privileges based on the caller's role, not the owner of the procedure. It also emphasizes the principle of least privilege. 'EXECUTE AS OWNER will not work in Native Apps. Option C is incorrect because granting privileges to PUBLIC is not a good practice. Option E is incorrect because security matters in Test Mode.

NEW QUESTION # 76
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?

Answer: E

Explanation:
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.

NEW QUESTION # 77
You are developing a Snowflake Native Application that needs to access user-provided data through a Secure Data Sharing. The consumer must explicitly grant access to their data container. Which approach provides the MOST secure and efficient method for allowing your application to access this data and ensure proper governance?

A. Request the consumer to create a share containing the desired data and grant usage on the share to your application's account. The application then imports this share into its own environment.
B. Require the consumer to create a database from their share within your application's environment.
C. Your application creates a secure view on the consumer's data container, allowing only specific data to be accessed.
D. Instruct the consumer to create a database role in their account and grant it all necessary privileges on the data container, then grant that role to your application's account.
E. Implement a custom API endpoint that the consumer must call to securely transmit their data to your application.

Answer: A

Explanation:
Sharing is the recommended approach. This mechanism allows the consumer to grant your application access to a subset of their data. By granting usage on the share, the consumer maintains control over what data your application can see. Creating a database from the share within the application's environment isn't necessary and adds complexity. Database roles are also not the preferred approach, as they can grant excessive privileges. Secure Views are possible but might not be the best architecture and increases risk and complexity. Building a custom API significantly increases the overhead to build a secure access method.
