Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application that requires robust role-based access control. The application provides data transformation services to consumer accounts. You want to define distinct roles for different levels of access: 'TRANSFORMER_ADMIW (full control), 'TRANSFORMER USER (execute transformations), and 'TRANSFORMER OBSERVER (read-only access to metadata). In the setup script, which SQL statements are the MOST secure and efficient way to achieve this while adhering to Snowflake's recommended practices for application roles?

A)

B)

C)

D)

E)

2. You are preparing to publish a Snowflake Native Application on the Snowflake Marketplace. You have successfully built and tested the application in your development account. Which of the following steps are CRITICAL for preparing the application listing metadata and ensuring a smooth onboarding experience for consumers?

A) Thoroughly test the application installation and upgrade process in a separate Snowflake account (ideally one that mimics a typical consumer environment) to identify and resolve any potential issues.
B) Ensure all necessary data governance and security measures are in place, including compliance with relevant regulations (e.g., GDPR, CCPA). Clearly document these measures in the application listing.
C) Provide a comprehensive and user-friendly application description that clearly outlines the application's functionality, benefits, and intended use cases. Include screenshots and/or videos demonstrating the application in action.
D) Define a clear pricing model (e.g., free, per-use, subscription) and accurately estimate the resource consumption (Snowflake credits) required for typical application usage. Include a free trial period if possible.
E) The listing should include a well-defined support strategy, outlining how you will handle customer inquiries, bug reports, and feature requests. Provide contact information and estimated response times.

3. Consider the following Snowflake Native Application design scenario: You are building a data enrichment application. This application requires a consumer to grant usage on a specific database in their account. The application will then use a user-defined function (UDF) to access and enrich the dat a. To minimize the risk of data exposure and adhere to best practices, which of the following approaches should you take when designing the UDF?

A) Create the UDF with the EXTERNAL_ACCESS' keyword to explicitly allow it to access data outside of the application package.
B) Create the UDF with the 'VOLATILE' keyword to ensure it only runs when explicitly called, limiting the potential for unintended data access.
C) Create the UDF with the 'IMMUTABLE keyword to prevent any data modification within the consumer's database.
D) Create the UDF without any special keywords, relying solely on the consumer's permissions to control data access.
E) Create the UDF with the 'SECURE keyword and implement granular access control within the UDF code, restricting access based on the application role.

4. You are developing a Snowflake Native App that provides data enrichment services to consumer accounts. The app requires access to both a secure internal API (accessible only within your provider account) and the consumer's data warehouse. Which of the following components and configurations are necessary to facilitate this access while adhering to Snowflake's security best practices?

A) A UDF (User-Defined Function) defined in the application package that invokes the secure internal API using a secured API integration, and grants OWNERSHIP on it to the APPLICATION role. The consumer grants USAGE on their database to the application role.
B) A Python UDF defined in the application package that connects to the secure internal API using a secured API integration with allowed egress network policy that only allows connections from the app's deployment region. The consumer shares their database with the provider account through a data sharing arrangement.
C) A Stored Procedure defined in the application package that invokes the secure internal API via network rule with outbound traffic allowed only for the app, and utilizes a reader account to securely query the consumer s data with the use of SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES().
D) A Java UDF defined in the application package uses JDBC connection to access a secure internal API endpoint. The consumer grants USAGE privilege to the application on their schemas.
E) A Snowpark function that leverages the SNOWFLAKCORE.AUTHZ.PASS PRIVILEGES() function with the application role executing the code. The app requires the consumer to create a shared secret to access their API.

5. A data analytics company, 'Data Insights Pro', is developing a Snowflake Native Application to provide advanced customer segmentation analysis. They plan to monetize this application through the Snowflake Marketplace. They want to ensure that only a specific set of customer accounts can access and install their application during the initial beta testing phase. Which of the following steps must they perform to achieve this?

A) Create a public listing with a very high price to deter unintended installations, then manually adjust the price to zero for beta testers.
B) Publish the application directly to the Snowflake Marketplace without creating a listing, and then share the installation URL with the selected customer accounts.
C) Create a private listing on the Snowflake Marketplace and share it with the specific customer accounts by explicitly granting access to their Snowflake account identifiers.
D) Use Snowflake's data sharing feature to share the application package with the customer accounts.
E) Create a public listing on the Snowflake Marketplace and rely on Snowflake's built-in usage monitoring to identify the intended customer accounts.
