Options B and E are correct. Option B implements the data access framework with least privilege using secure views. Granting direct SELECT access (Option C) to the table to the invoker role is not recommended because it exposes the entire table and it will not work as IR UDF cannot directly access consumer data. Using external services(Option D) is an option, but not the most efficient for accessing local data. Option A won't work directly without proper data access framework as it is. Data access framework will solve this issue. Using an intermediate SP as OWNER called by the UDF as INVOKER is a valid approach.

Since the database 'app_db' was created with 'MANAGED ACCESS, simply creating the schema using 'CREATE SCHEMA app_db.internal_schema;' inherits the managed access properties. Granting 'USAGES is necessary to allow the role to access objects within the schema. Granting ownership is typically not required and could unnecessarily elevate privileges. Option B, while valid syntax, will result in an error, the MANAGED ACCESS is already inherited from the DATABASE and therefore redudnant. Option D is too permissive. Option E, using all privileges, is not best security practice, rather only the specific USAGE is needed in this scenario.

The recommended approach is to use the 'APPLICATION_SETTINGS' object (Option E). Snowflake provides this mechanism specifically for storing and retrieving consumer-specific configuration data securely within a Native App. 'APPLICATION SETTINGS' allows providers to define configurable parameters that consumers can set during installation or later through a setup interface. These settings are securely managed by Snowflake and accessible within the application's logic using Javascript or SQL. Other options are not recommended for the following reasons: A: Environment variables are not consumer-specific and are generally used for application-wide settings, not per-consumer configurations. B: Storing configuration data in a consumer-specific stage is not secure or recommended, as it bypasses Snowflake's built-in security mechanisms. C: Creating tables directly in the consumer's account requires additional permissions and can be more complex to manage. D: Secured views are generally intended for data sharing, not for storing configuration parameters.

The correct answer is (C). Snowflake Native Apps allow you to create separate application packages for each version. Consumers can then choose the version that best suits their needs. Using the 'APPLICATION ROLE allows for controlling access to different resources within the application, ensuring proper data governance and security. Options A, D, and E are less efficient or not directly supported by the Snowflake Native App framework. Option B is partially correct that you can leverage application role but version control is through separate application packages.

The 'EXTERNAL ID must be globally unique. The 'PATCH' allows for minor bug fixes. The 'SOURCE PACKAGE' indicates the application to clone the version from, which should be in the same account. The 'VERSION' argument is not just a display name; it is part of the version identifier and has implications for compatibility. 'SOURCE_PACKAGE' is required. 'SYSTEM$REGISTER_APPLICATION_PACKAGE_VERSION' takes these parameters, and requires package to be in the same account.
