Explanation:
* RAML file contains lot of information that could be considered as "not API-describing". Sort of "economy-class" members. Equally important, but not necessarily part of the main RAML file.
* Through !includes, RAML allows us to build file-distributed API definitions, which is not only useful to encourage code reuse but also improves readability.
* We can create RAML fragments with such code and then include them in main RAML project using !include like:
types:
Book: !include bookDataType.raml and examples:
input: !include bookExample.raml
* Additionally for

An organization is beginning to follow Mulesoft's recommended API led connectivity approach to use modern API to support the development and lifecycle of the integration solutions and to close the IT delivery gap.
What distinguishes between how modern API's are organized in a MuleSoft recommended API-led connectivity approach as compared to other common enterprise integration solutions?

A. The API interfaces are specified as macroservices with one API representing all the business logic of an existing and proven end to end solution

B. The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes

C. The API implementation are built with standards using common lifecycle and centralized configuration management tools

D. The APIO implementations are monitored with common tools, centralized monitoring and security systems

B. The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes

Explanation:
Correct answer is The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes.

Refer to the exhibits.

A. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "vars.address"
4. 4. }

B. 1. 1. {
2. 2. orderkey: "attributes.shippingaddress.order",
3. 3. addresskey: "payload"
4. }

C. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "address"
4. }

D. 1. 1. {
2. 2. orderkey: "attributes.order",
3. 3. addresskey: "vars.address"
4. }

A. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "vars.address"
4. 4. }

Explanation:
Correct answer is as below. In this case address will be stored in a variable. Hence payload will not be overwritten and will contain order details
{
orderkey: "payload.order",
addresskey: "vars.address"
}
