- C. Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager
- D. Upload the Mule application's JAR file to the API instance in API Manager
Answer: B
Explanation:
Correct answer is Modify the API implementation to use auto-discovery to register with API Manager API Autodiscovery Configuring autodiscovery allows a deployed Mule runtime engine (Mule) application to connect with API Manager to download and manage policies and to generate analytics data. Additionally, with autodiscovery, you can configure your Mule applications to act as their own API proxy.
When autodiscovery is correctly configured in your Mule application, you can say that your application's API is tracked by (green dot) or paired to API Manager. You can associate an API in a Mule setup with only one autodiscovery instance at a given time.
