Snowflake SnowPro Specialty - Native Apps Sample Questions:

Question 1

A Native App provider wants to use a parameter in their MANIFEST.yml to dynamically control the number of worker threads a stored procedure uses. The desired behavior is to allow the consumer to configure this value. Considering security best practices, which of the following parameter definitions in the 'MANIFEST.yml' is the MOST appropriate?

A.

B.

C.

D.

E.

Question 2

A Snowflake Native App aims to provide data masking as a service. The app needs to access customer data, apply masking policies based on app-managed configuration, and store the masked data either in the customer's account or in the app's managed account based on customer preference. Which of the following steps and considerations are CRUCIAL for designing this application, focusing on security and privilege management? (Select all that apply)

A. Implement the data masking logic within stored procedures that execute with the CALLERS RIGHTS to leverage the customer's existing masking policies.
B. Use stored procedures that execute with DEFINER'S RIGHTS and request necessary READ privileges on the customer's database and tables.
C. Use secure views to access the customer's data, ensuring that the app only sees the data it is authorized to access based on requested READ privileges.
D. Ensure the application uses the SNOWFLAKE.CORE.INVOKE FUNCTION to call data masking policies with the consumer's data.
E. Request the OWNERSHIP privilege on the customer's tables to ensure full control over data masking.

Question 3

You are tasked with deploying a Snowflake Native Application that performs real-time data analysis. The application requires a warehouse to run and a user with specific privileges to access dat a. You want to automate the deployment process as much as possible, including warehouse creation, user provisioning, and privilege granting, all within the application package. Given the security considerations and best practices for Snowflake Native Applications, which of the following approaches is the MOST secure and recommended?

A. Employ a secure deployment pipeline that leverages a separate, pre-authorized Snowflake account to provision the warehouse and useL The application package then only includes the application logic, assuming the resources already exist.
B. Utilize the 'INSTALL' privilege when creating the application package and execute the SQL script (containing 'CREATE WAREHOUSE, 'CREATE USER , and 'GRANT) within the application's setup script using the 'EXECUTE IMMEDIATE command. This allows the application to create resources within the consumer's account.
C. Request the consumer to manually create the warehouse and user with the required privileges before installing the application. Provide detailed instructions in the application documentation.
D. Use a setup script within the application package, granting it the 'APPLY APPLICATION PASSTHROUGH PRIVILEGES privilege. This will enable the application to inherit the privileges of the user who installed the application, allowing it to create the warehouse and user on their behalf.
E. Include a SQL script within the application package that uses the 'CREATE WAREHOUSE, 'CREATE USER , and 'GRANT commands to create the warehouse, user, and grant necessary privileges. The script will be executed by the consumer upon installation.

Question 4

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 guarantee that the 'app_data.configuration' table always contains the latest version of the 'api_endpoint' parameter, overwriting any existing value.
B. 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.
C. To handle potential errors that may occur if the 'api_endpoint' parameter is already defined in the consumer's account.
D. To ensure that the 'INSERT statement only executes if the table is empty.
E. To optimize the performance of the 'INSERT statement by avoiding unnecessary insertions when the configuration parameter already exists.

Question 5

A data science team within your organization is developing a Snowflake Native App that needs to access and process customer data stored in a Snowflake database. The app must only access data for customers residing in the 'USA' region. The team has created a custom role 'APP ROLE for the app to use. Which of the following is the MOST secure and efficient way to grant the app the necessary permissions to read the filtered data? Assume a secure view approach is preferred over direct table access.

A. Grant the 'APP_ROLE the 'USAGE privilege on the database and schema containing the customer data table. Data filtering should still be handled by the app.
B. Create a secure view that filters customer data to include only customers in the 'USA' region and grant the SAPP ROLE the 'SELECT privilege on the secure view.
C. Grant the SAPP ROLE the 'OWNERSHIP' privilege on the base customer data table and implement data filtering logic within the app itself.
D. Create a standard view (non-secure) that filters customer data to include only customers in the 'USA' region and grant the 'APP_ROLE the 'SELECT' privilege on this view.
E. Grant the 'APP_ROLE the 'SELECT privilege on the base customer data table and rely on row-level security policies defined on that table.
