Snowflake SnowPro Specialty - Native Apps Sample Questions (Q323-Q328):

NEW QUESTION # 323
You are building a Snowflake Native Application that provides a data transformation service. You want to allow consumers to configure certain aspects of the transformation pipeline (e.g., the name of the target table, specific transformation logic). What are the recommended approach(es) to allow consumers to customize the application's behavior without directly modifying the application code?

A. Expose parameters within the setup script and stored procedures that consumers can set during application installation or execution.
B. Require consumers to fork the application's repository and modify the SQL code directly.
C. Include default configurations within a file on the external stage, which consumers are expected to download, modify, and then upload back as a different file for the application to load.
D. Implement a configuration table within the application's schema that consumers can update with their desired settings. The application code reads these settings at runtime.
E. Utilize Snowflake's Secure UDFs (User-Defined Functions) and allow consumers to provide their own UDFs as configuration.

Answer: A,D

Explanation:
Options B and D are correct. Exposing parameters in the setup script and stored procedures is a standard way to allow customization during installation and execution. A configuration table provides a flexible way for consumers to manage settings that can be read by the application. Option A is incorrect because forking the repository makes it difficult to manage updates and maintain security. Option C has security implications, as malicious code can be injected through user-defined UDFs. Option E is incorrect as the file download, modify, and upload method are complex for users to configure.

NEW QUESTION # 324
You've installed a Snowflake Native Application that provides advanced data analytics. The application requires a consumer-defined function (UDF), 'MASK SENSITIVE DATA, to be created in their account and used by the application. The application's setup script includes logic to check for the UDF's existence, but you want to ensure the application gracefully handles the case where the consumer has not yet created the UDF. Which of the following strategies can you implement to improve the application's resilience and provide a better user experience in this scenario? Select all that apply.

A. In the application's setup script, create a placeholder UDF with the same name and signature as 'MASK SENSITIVE DATA' that returns 'NULL'. The application logic can then handle 'NULL' values appropriately until the consumer provides the actual UDF.
B. Require the consumer to create the UDF before installing the application. The application setup script should fail if the UDF is not found, preventing installation.
C. Within the application's SQL code, use the 'TRY FUNCTION' function to call 'MASK SENSITIVE DATA'. If the UDF does not exist, 'TRY FUNCTION' will return 'NULL' instead of raising an error.
D. Implement error handling within the application's code to catch the 'SQL compilation error: UDF does not exists exception. Provide a user-friendly error message and instructions on how to create the UDF.
E. Dynamically generate the application code using a stored procedure, only including the parts of the code that rely on if the function exists. Use 'SYSTEM$GET PRIVILEGES()' to check existence.

Answer: C,D

Explanation:
Options B and C are the best strategies for handling the missing UDF gracefully. 'TRY_FUNCTION' allows the application to continue running even if the UDF is not present, while error handling provides a clear and informative message to the user. Option A is problematic because it introduces a UDF that is not the intended function, potentially leading to data inconsistencies. Option D creates a rigid dependency and a poor user experience. Option E adds unnecessary complexity.

NEW QUESTION # 325
You are developing a Snowflake Native Application intended for the Snowflake Marketplace. The application provides data transformation services, leveraging external functions (UDFs) that invoke a REST API hosted on AWS Lambd a. You need to ensure the secure and compliant invocation of this external API from your application while adhering to Snowflake's best practices. Which of the following steps represent the MOST secure and recommended approach for configuring and invoking the external function?

A. Create an API integration object in Snowflake that stores the AWS Lambda function's URL and credentials (API key) directly within the integration. Grant the necessary permissions to the application's roles to use the API integration. Define the external function to call the Lambda function URL directly, referencing the API key from the integration object.
B. Use Snowflake's built-in network rules to allow outbound traffic to all AWS IP ranges. Store the API key directly in the UDF definition as an environment variable.
C. Store the AWS Lambda function's URL and credentials (API key) in a configuration table within the Snowflake Native Application package. The external function retrieves these credentials from the configuration table at runtime. Configure an alert if the configuration table is modified.
D. Create an API integration object in Snowflake, configuring a secure authentication mechanism such as AWS IAM roles or OAuth 2.0. Define the external function to use the API integration, providing the necessary parameters for authentication. Configure network policies and secrets (using Snowflake secrets) to secure the connection. Ensure your AWS Lambda function validates the incoming request's identity.
E. Expose the AWS Lambda function publicly with no authentication. Configure the external function in Snowflake to point to the public Lambda URL. Document to consumers that the API has no security.

Answer: D

Explanation:
The MOST secure and recommended approach (Option C) involves creating an API integration object in Snowflake with secure authentication (IAM roles or OAuth 2.0), defining the external function to use the integration, and leveraging network policies and secrets for enhanced security. This aligns with Snowflake's security best practices. Option A is less secure as it stores the API key directly in the integration. Option B is completely insecure. Option D poses a security risk storing credentials within a table. Option E involves blanket outbound access and storing the API key directly in the UDF (bad).

NEW QUESTION # 326
You are designing a Snowflake Native Application that requires managing application roles and permissions. Which of the following best practices should be followed regarding application roles and permissions in a Snowflake Native Application?

A. Grant all necessary privileges to the 'APPLICATION' role during setup, as this simplifies permission management for consumers.
B. Bundle all application logic within a single stored procedure owned by the 'APPLICATION' role.
C. Define granular application roles with specific permissions, and provide documentation to the consumer on how to grant these roles to their users.
D. Avoid using application roles altogether and rely solely on the consumer's existing roles and permissions.
E. Use the 'EXECUTE AS OWNER clause for all stored procedures to avoid granting explicit privileges to the application roles.

Answer: C

Explanation:
Defining granular application roles is crucial for security and maintainability. Consumers need to grant these roles to their users, so clear documentation is essential. Granting all privileges to the 'APPLICATION' role is overly permissive. 'EXECUTE AS OWNER can introduce complexities and might not always be appropriate. Relying solely on the consumer's roles limits the application's ability to control access. Bundling all logic into a single procedure hinders modularity and maintainability.

NEW QUESTION # 327
You are developing a Snowflake Native Application that requires secure access to external services for data enrichment. You choose to implement an External Function with API Integration. Which of the following security best practices are MOST important to implement when configuring the API Integration and the External Function to minimize security risks?

A. Grant usage on the API integration to PUBLIC role to allow all users to invoke the external function.
B. Disable network policies on the API Integration to avoid accidental blocking of traffic.
C. Store any sensitive credentials required by the external service directly in the External Function's code body for easy access.
D. Configure 'AWS IAM ROLE ARNS or similar parameters (depending on cloud provider) to grant Snowflake the least privilege access to the specific resources on the external service required by the function.
E. Use the parameter in the API Integration to restrict access to only the trusted IP addresses of the external service.

Answer: D,E

Explanation:
Options B and D are correct. Using restricts the allowed source IPs for connection to the External Function, reducing the attack surface. Using SAWS IAM ROLE ARN' (or equivalent) with the principle of least privilege ensures that Snowflake only has the necessary permissions on the external service, minimizing the potential impact of a compromised function. Option A is incorrect because granting usage to PUBLIC is a security risk. Option C is incorrect because storing credentials directly in code is a bad practice. Option E is incorrect because network policies should be in place for security. The other options either create a broad attack surface or directly expose sensitive information.
