Explanation

Correct Answer: Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs.

*****************************************

>> All customizations for the end-user application should be handled in "Experience API" only. Not in Process API

>> We should use tiered approach but NOT always by creating exactly one API for each of the 3 layers. Experience APIs might be one but Process APIs and System APIs are often more than one. System APIs for sure will be more than one all the time as they are the smallest modular APIs built in front of end systems.

>> Process APIs can call System APIs as well as other Process APIs. There is no such anti-design pattern in API-Led connectivity saying Process APIs should not call other Process APIs.

So, the right answer in the given set of options that makes sense as per API-Led connectivity principles is to allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs. This way, some future Process APIs can make use of that data from System APIs and we need NOT touch the System layer APIs again and again.

In MuleSoft’s ecosystem, when a Process API needs to consume a System API (published to Exchange and protected by OAuth 2.0), the recommended approach is to utilize the REST Connect Connector. Here’s how it aligns with best practices:

Automated Connector Generation:

When a RAML or OAS specification is published in Exchange, MuleSoft automatically generates a REST Connect Connector for that API. This connector simplifies integration as it abstracts the complexity of making HTTP requests and handling OAuth authentication.

Streamlined Integration:

The Process API can import this generated connector from Exchange and configure OAuth credentials, streamlining secure access to the System API without manual HTTP setup.

Why Option C is Correct:

Using the REST Connect Connector directly leverages MuleSoft’s automated tooling, minimizing manual configurations and ensuring a more maintainable integration.

Explanation of Incorrect Options:

Option A (importing an OAuth module) is unnecessary; OAuth is handled within the connector’s configuration.

Option B (property YAML files with HTTP requests) involves manual setup, which is more error-prone and not recommended.

Option D (manually updating POM file) does not directly aid in invoking an API through Exchange.
