   An organization is integrating a third-party security policy management tool with an SDN environment. The tool can enforce policies via API, but it requires a full network topology view to function correctly. The SDN controller provides a REST API that exposes topology information. However, the tool's API client is not compatible with the controller's API authentication method. What is the most effective way to resolve this?

   • AReplace the third-party tool with a different tool that supports the controller's authentication.
   • BChange the SDN controller's authentication method to match the tool's expectations.
   • CDevelop a custom adapter that translates between the tool's API and the SDN controller's API, including authentication.
   • DManually export the topology from the controller and import it into the tool.
