Snowflake SnowPro Specialty - Native Apps Sample Questions:

Question 1

You are tasked with designing a Snowflake Native App that requires multiple roles with different levels of access to its functionalities. The app needs to define which roles can perform specific actions, such as viewing data, modifying data, or managing app settings. Which of the following methods are CORRECT ways to control role-based access within a Snowflake Native App? (Select all that apply)

A. Creating separate versions of the application for each role, with each version containing only the functionalities that the role is allowed to access.
B. Defining application roles within the provider account and mapping them to consumer roles during the installation process. These application roles can then be used for fine-grained access control.
C. Granting specific privileges to roles directly within the application's stored procedures and functions, checking the current role using and conditionally executing code based on the role.
D. Using the 'allowed_roleS section in the manifest file to restrict access to certain functionalities based on the consumer's roles. This ensures that only authorized roles can interact with those components.
E. Defining roles within the setup script with specific privileges and instructing the consumer to grant their existing roles to these newly created roles.

Question 2

A Snowflake Native App provider is troubleshooting an issue where consumer installations intermittently fail. The provider suspects that certain installation parameters are causing conflicts. The provider has implemented an event table to track installation attempts and errors. Which of the following SQL statements is the MOST effective way to identify the installation parameters that are most frequently associated with failed installations? Assume the event table is named "INSTALLATION EVENTS and contains columns 'INSTALLATION ID, 'STATUS' (success/failure), and PARAMETERS' (a VARIANT column storing a JSON object of installation parameters).

A.

B.

C.

D.

E.

Question 3

You are developing a Snowflake Native Application that provides data enrichment services. You want to monetize your application through the Snowflake Marketplace using a custom, usage-based pricing model. You need to track the number of API calls made by each consumer account and bill them accordingly. Which of the following steps are necessary to implement this in your application and listing configurations?

A. Use Snowflake's data sharing capabilities to share a billing table with consumer accounts, tracking API calls externally and managing billing outside of the Snowflake Marketplace.
B. Implement custom code to track API calls in a table within the application package and use a scheduled task to generate billing reports manually. This report is then shared outside of Snowflake Marketplace.
C. Implement a metering function within your Native Application using 'snowflake.snowpark.functions.metering'. Configure your application listing with a CONSUMPTION listing type and define metering events based on API calls made. Set the cost per metering event.
D. Implement a metering function within your Native Application using 'snowflake.snowpark.functions.metering'. Configure your application listing with a STANDARD listing type and set a base price.
E. Implement a metering function using stored procedures, record API usage in a dedicated table within your application's container and use 'CREATE NOTIFICATION INTEGRATION' to send billing data to an external system for invoice generation.

Question 4

A provider is testing their Snowflake Native Application in a consumer environment. The application includes a Streamlit app that displays data from a table provisioned in the consumer account. The consumer reports that the Streamlit app is displaying an errorrelated to accessing the table. The 'streamlit.secretS dictionary is used to store the database connection details. The application role app_role' is designed to have access to the table. Which of the following could be potential causes of the problem, assuming the connection details are valid?

A. The 'app_role' does not have the privilege on the database containing the table.
B. The consumer has not shared the database containing the table with the provider account.
C. The 'app_role' does not have the 'SELECT privilege on the table.
D. The 'streamlit.secretS dictionary is not accessible to the application due to incorrect file permissions.
E. The Streamlit app is not properly configured to assume the when executing queries.

Question 5

A Snowflake Native Application developer is troubleshooting an issue where application installations are failing intermittently in consumer accounts. The application relies on a specific version of a Python library. What is the MOST likely cause of this issue, and what steps can the developer take to resolve it within the Snowflake Native App framework?

A. The required Python library version is not available in the consumer's Snowflake environment. The developer should bundle the specific version of the Python library with the application package, leveraging the manifest file.
B. A firewall rule on the consumer's network is blocking access to the application. The consumer needs to whitelist the application's IP address.
C. The consumer's Snowflake environment lacks sufficient compute resources. Increase the warehouse size on the consumer's account.
D. The application's code contains a bug that only manifests in specific Snowflake regions. The developer should add region-specific exception handling.
E. The application is trying to access a private endpoint not accessible to the consumer. The consumer should setup a network rule for this endpoint.
