Snowflake SnowPro Specialty - Native Apps Sample Questions (Q220-Q225):

NEW QUESTION # 220
You are tasked with developing a Snowflake Native App that leverages a Partner provided secret using an external function which will send the processed data to their system. You plan to store the OAuth information to be used by the external function in a secret object managed by Snowflake. Which of the following steps are NECESSARY to ensure secure and correct setup of this app? Select all the options that apply.

A. Grant the 'USAGE privilege on the API integration to the application role if the external function requires an API integration. GRANT USAGE ON API INTEGRATION TO APPLICATION ROLE
B. Bypass storing the OAuth token in Snowflake and instead rely on passing it as a parameter to the external function from the consumer account, documented clearly for the consumer's security responsibilities.
C. Grant the 'IMPORTED PRIVILEGES privilege on the database containing the Secret object to the application role. GRANT IMPORTED PRIVILEGES ON DATABASE TO APPLICATION ROLE '
D. Store the OAuth token directly within the external function's definition as a variable, ensuring it is encrypted using AES ENCRYPT before deployment.
E. Create a Secret object in Snowflake to store the OAuth token securely and reference it within the external function using 'SYSTEM$GET_SECRET function. Ensure proper access rights on the Secret object.

Answer: A,C,E

Explanation:
Storing the OAuth token directly in the function (A) is insecure. Passing the OAuth token from the consumer (E) is not a recommended practice. The correct approach is to use Snowflake's Secret object (B) to store the token securely. The application role needs 'IMPORTED PRIVILEGES on the database containing the secret (C) to access the secret. The 'USAGE privilege on the API integration(D) is also needed if the external function leverages an API integration.

NEW QUESTION # 221
You've built a Snowflake Native Application and are ready to test it in test mode. The application utilizes both internal stages and external stages for data storage. Which of the following statements accurately describe the behavior of stages and data access during test mode installations from the provider's perspective?

A. The provider can configure specific external stages to be accessible in test mode by granting appropriate privileges to the application role and explicitly defining these stages in the setup script.
B. During test mode, the provider has full access to all data stored in both internal and external stages associated with the application, mimicking the access rights in a production environment.
C. Internal stages defined within the application package are accessible to the application code running in test mode. Data placed in these stages before installation is available immediately.
D. Data loaded into internal stages during test mode is automatically persisted to the consumer's account upon final installation of the application.
E. External stages, regardless of their access permissions, are inaccessible during test mode installations to prevent unintended data leakage.

Answer: A,C

Explanation:
Option A is correct because internal stages are accessible in test mode, allowing providers to pre-populate data for testing. Option C is correct because external stages can be configured for access with proper permissions. Option B is incorrect, as external stages can be accessed. Option D is incorrect because test mode data doesn't persist to consumer's account automatically. Option E is partially incorrect; the Provider must configure the external stages.

NEW QUESTION # 222
A financial services company is developing a Snowflake Native App. It needs to securely access external market data via an API and store the processed results in a consumer-provided table. Considering security best practices and the Snowflake Native App Framework limitations, which of the following approaches represents the MOST secure and recommended implementation for this scenario?

A. Employ a Snowflake external function, configured with a service account, which invokes an API integration stored in the provider account. The external function returns the data, which is then inserted into a consumer-owned table using a stored procedure and INSERT statements, where the application role has been granted the necessary INSERT privilege.
B. Utilize a Java UDF with the 'network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer- provided table by using the application role with INSERT privilege granted by consumer.
C. Use a Snowflake external function with an API integration that passes the API key as a parameter. Store the processed data in a consumer-provided table using dynamic SQL.
D. Utilize a Python UDF with the 'external network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer-provided table by using the application role. API key is stored in snowflake secret.
E. Use a Snowflake external function with an API integration, configured with a service account that has the necessary permissions to access the API. Store the processed data in a consumer-provided table using stored procedures and INSERT statements using the application role.

Answer: A

Explanation:
Extemal functions with API integrations are recommended for secure external API access. Using a service account for authentication is a best practice. Stored procedures allow for managed access control to consumer-provided tables. It is safer and allows for managed security. Option E combines these best practices for a secure and robust solution.

NEW QUESTION # 223
You are preparing to list your Snowflake Native Application on the Snowflake Marketplace. You want to restrict its availability to specific Snowflake regions and also require consumers to agree to a custom End User License Agreement (EULA) before installation. Which steps are essential during the listing creation process to achieve this?

A. During listing creation, select the 'Custom EULA' option and provide the EULA text directly within the designated field. Configure the 'Availability' section to specify the allowed regions.
B. Specify the allowed regions in the 'Availability' section of the listing. Upload a text file containing the EULA and mark it as 'Required Agreement' in the listing settings.
C. Configure the 'Availability' section of the listing to specify allowed regions. Upload the EULA as a PDF document within the 'Documentation' section.
D. Use the Snowflake CLI to programmatically set the allowed regions using the 'snowflake marketplace application update' command. Include a link to an external website hosting the EULA in the listing description.
E. Regions are inherently globally available so it cannot be restricted. Include the EULA within the code of the application, forcing the user to acknowledge it through the code.

Answer: A

Explanation:
Option D is the correct answer. The Snowflake Marketplace provides specific fields to enter a custom EULA directly. Also the availability of the application can be restricted based on Snowflake regions. Options A, B, and C provide partially correct steps, but do not cover the complete solution. A PDF or link doesn't guarantee agreement. Option E has a false statment that regions cannot be restricted.

NEW QUESTION # 224
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. 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.
B. 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.
C. 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.
D. 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.
E. 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.

Answer: E

Explanation:
Option C is the most appropriate. Snowflake Native Apps are designed to operate within a secure sandbox. The INSTALL privilege, combined with EXECUTE IMMEDIATE within the setup script, allows the application to create the necessary resources within the consumer's account in a controlled and automated manner. Option A is less secure, as it relies on the consumer executing arbitrary SQL. Option B increases the burden on the consumer. option D is overly complex for this scenario. APPLY APPLICATION PASSTHROUGH PRIVILEGES is about leveraging the consumer's privileges for accessing THEIR data, not for the creation of resources (option E).
