An API instance of type API endpoint with API proxy is created in API manager using an API specification from Anypoint Exchange. The API instance is also configured with an API proxy that is deployed and running in CloudHub.
An SLA- based policy is enabled in API manager for this API instance.
Where can an external API consumer obtain a valid client ID and client secret to successfully send requests to the API proxy?


A. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy


B. In Anypoint Studio, from components generated by APIkit for the API specification


C. In Anypoint Studio, from components generated by Rest Connect for API specification


D. In Runtime Manager, from the properties tab of the deployed approved API proxy





A.
  In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy

Explanation:
* When a client application is registered in Anypoint Platform, a pair of credentials consisting of a client ID and client secret is generated.
* When the client application requests access to an API, a contract is created between the application and that API.
* An API that is protected with a Client ID Enforcement policy is accessible only to applications that have an approved contract.

A. examples: !include StudentExample.raml


B. examples: #import StudentExample.raml


C. examples: !include examples/StudentExample.raml


D. examples: #import examples/StudentExample.raml





C.
  examples: !include examples/StudentExample.raml

To include property. To keep the API definition concise, you can include external content, such as documentation, schemas, and frequently used patterns outside the definition itself. The parser interprets !include as if the content of the externally-hosted file or a URL were declared in-line.
To use the fragments in RAML you have to include the exact path(copy the path) of that fragment you want to use as shown below Option 3 is the correct as correct syntax is examples: !include examples/StudentExample.raml

Refer to the exhibit.
