Snowflake SnowPro Specialty - Native Apps Sample Questions (Q318-Q323):

NEW QUESTION # 318
You are designing a Snowflake Native App that includes a Streamlit I-Jl. The Streamlit app needs to access data stored in a secure table within the consumer's account. What are the recommended and MOST secure methods for granting the Streamlit app access to this data, considering the principle of least privilege? Select all that apply.

A. Create a secure view on top of the table and grant 'SELECT privilege on the view to the application role. Publish the View via 'show published objects in application package'.
B. Create an external function that retrieves the data and grant 'USAGE on the external function to the application role.
C. Grant *SELECT privilege directly on the table to the application role.
D. Grant the ' IMPORTED PRIVILEGES' privilege on the database containing the table to the application role.

Answer: A,D

Explanation:
Granting 'IMPORTED PRIVILEGES (A) on the database allows the application to inherit privileges defined within the consumer's account, following the principle of least privilege. Creating a secure view (C) and granting SELECT on the view to the application role provides a controlled interface to the data. Directly granting SELECT on the table (B) is less secure, as it grants direct access. External functions (D) introduce unnecessary complexity and potential security risks. Granting 'ACCOUNTADMIW (E) is a significant security violation and should never be done.

NEW QUESTION # 319
A software company, 'Datalnsights', is developing a Snowflake Native Application that requires restricted access to a source data table in the consumer's account. Datalnsights wants to ensure that only the application can access the data, and the consumer cannot directly query it. What is the MOST secure and recommended approach Datalnsights should use within their application package to grant access?

A. Granting 'SELECT privilege directly on the source data table to the application role.
B. Creating a secure view on top of the source data table and granting 'SELECT privilege to the application role on the view.
C. Exposing the table directly through the application's setup script using 'GRANT SELECT ON TABLE TO APPLICATION ROLE app_role' .
D. Granting the ' USAGE privilege on the database and schema containing the source data table directly to the application role.
E. Using a secure UDF within the application to access the source data table, ensuring data masking and redaction, with only the UDF being granted SELECT privileges on the table.

Answer: E

Explanation:
Using a secure UDF is the recommended approach. By encapsulating the data access within a secure UDF, you can control precisely how data is accessed and potentially mask sensitive information. Options A, B and E grants direct access which contradicts the requirement for data restriction. While a secure view (C) adds a layer of indirection, a UDF provides greater flexibility and control over the data access logic and potential redaction.

NEW QUESTION # 320
You are developing a Snowflake Native Application that provides a data enrichment service. This service requires the consumer to grant the application access to a specific table in their account. You want to ensure that upgrades to your application do not inadvertently break existing consumer configurations. You decide to use a versioned schem a. Which of the following steps are essential during the setup script execution to achieve this and maintain backward compatibility during future upgrades?

A. Create a versioned schema using 'CREATE SCHEMA VERSION = ' . Grant the application role 'USAGE on this versioned schema, and ensure all application logic references objects within this schema.
B. Create a secure view in the versioned schema that accesses the consumer's table. Grant the application role 'SELECT on this secure view. This provides a stable interface that isolates the application from direct changes to the consumer's table.
C. Create a new unversioned schema named 'APPLICATION' and install all application objects within it. This provides a consistent namespace for all consumers, regardless of the application version.
D. Grant the application role 'OWNERSHIP on the consumer's table directly. This allows the application full control and ensures consistent data access regardless of future schema changes within the application.
E. Define a custom role within the application package and grant it the necessary privileges to read the consumer's table via a secure view. Then, grant the application role the USAGE privilege on this custom role. This ensures that the application role can assume the custom role's privileges for data access.

Answer: A,B

Explanation:
Options B and D are correct. Creating a versioned schema allows for managing changes in your application's data structures. By creating a secure view and granting the application role 'SELECT on it, you isolate your application from direct modifications to the consumer's table, ensuring backward compatibility. Option A is incorrect because an unversioned schema doesn't address the need for backward compatibility during upgrades. Option C is generally discouraged due to security concerns of granting ownership. Option E, while useful, is not the core reason to use a versioned schema to protect from consumer changes.

NEW QUESTION # 321
You've built a Snowflake Native Application that processes data and exposes a set of stored procedures to the consumer. You're implementing a CI/CD pipeline using GitLab CI/CD for deploying updates. Your pipeline includes the following stages: linting, unit testing, integration testing, and deployment to a staging environment. During the integration testing stage, you want to verify that the exposed stored procedures function correctly against a representative dataset. What is the MOST effective approach for performing these integration tests?

A. Provision a dedicated Snowflake testing account with a representative dataset. Install the application version in this account and execute the stored procedures from within the account using Snowflake's SQL API or a Snowpark Python test framework.
B. Use the application's setup script to automatically create a test database populated with sample data when the application is installed. Integration tests can then run queries in this database to ensure the application functions correctly.
C. Execute the stored procedures directly from the GitLab CIICD runner using a Snowflake connection established with hardcoded credentials in the CI/CD configuration.
D. Mock the Snowflake environment entirely within the GitLab CI/CD runner and execute the stored procedures against the mock environment. This eliminates the need for a live Snowflake connection during testing.
E. Create a separate set of stored procedures within the application package specifically for testing purposes. These procedures should mimic the functionality of the production stored procedures and assert their behavior.

Answer: A

Explanation:
Option C is the MOST effective. It closely simulates the production environment by installing the application in a dedicated testing account with a representative dataset. This allows for realistic integration tests that verify the stored procedures' functionality. Option A is insecure due to hardcoded credentials. Option B is redundant and might not accurately reflect the behavior of the production stored procedures. Option D is difficult to implement accurately and might not catch all potential issues. Option E, while helpful for initial testing, doesn't provide the same level of confidence as testing against a fully installed application in a dedicated account.

NEW QUESTION # 322
You are developing a Snowflake Native Application package that provides a set of UDFs for data transformation. The UDFs require specific Snowflake privileges to access data in consumer accounts. Which of the following methods can ensure your application has the necessary privileges when installed in a consumer account? (Choose all that apply)

A. Use 'GRANT OWNERSHIP' to grant the APPLICATION role ownership of the target objects in the consumer account.
B. Create a separate role in the consumer account and grant the necessary privileges to that role. Have the application assume this role.
C. Leverage 'GRANT APPLICATION ROLE ... ON ..: statements in the setup script to grant the APPLICATION role the required privileges.
D. Instruct consumers to manually grant the necessary privileges to the APPLICATION role after installation.
E. Request the required privileges in the application package manifest file ('manifest.yml'

Answer: C,E

Explanation:
The application package 'manifest.yml' file is where you declare the resources your application needs and the privileges it requires. The 'GRANT APPLICATION ROLE ON statement, executed during the setup script, is the correct way to grant the APPLICATION role the necessary privileges on objects in the consumer account. Requiring consumers to manually grant privileges is not a scalable or secure solution. 'GRANT OWNERSHIP is generally not necessary or recommended as it gives the application full control over the object. Creating a separate role in the consumer account and having the application assume it is an overly complex solution when 'GRANT APPLICATION ROLE is available.
