Question 101

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.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.

C.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.

D.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.

E.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.
