Answer: B
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

NEW QUESTION # 141
What should this endpoint return? http://dev.acme.com/api/patients?name=John&surname=Bell
- A. Patient with surname as bell
- B. Patients with name as John and surname as Bell
- C. Patients with either name as John or surname as Bell
- D. Patient with name as John
Answer: B
Explanation:
Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a '?' Is added followed immediately by a query parameter.
To add multiple parameters, an '&' is added in between each.
Hence coming back to question, endpoint would return Patients with name as John and (and is very important here) surname as Bell

NEW QUESTION # 145
Following Mulesoft's recommended API-led connectivity approach , an organization has created an application network. The organization now needs to create API's to transform , orchestrate and aggregate the data provided by the other API's in the application network. This API should be flexible enought ot handle the data from additional API's in future.
According to Mulesoft's recommended API-led connectivity approach , what is the best layer for this new API?
- A. Process layer
- B. Data layer
- C. System layer
- D. Experience layer
Answer: A
Explanation:
Correct answer is process layer as all the orchestration and transformation logic should be in process layer as per Mulesoft's recommended approach for API led connectivity.
API-led connectivity is a methodical way to connect data to applications through reusable and purposeful APIs. These APIs are developed to play a specific role - unlocking data from systems, composing data into processes, or delivering an experience.
What are the APIs that enable API-led connectivity?
API-led connectivity provides an approach for connecting and exposing assets. With this approach, rather than connecting things point-to-point, every asset becomes a managed API - a modern API, which makes it discoverable through self-service without losing control.
The APIs used in an API-led approach to connectivity fall into three categories:
System APIs - these usually access the core systems of record and provide a means of insulating the user from the complexity or any changes to the underlying systems. Once built, many users, can access data without any need to learn the underlying systems and can reuse these APIs in multiple projects.
Process APIs - These APIs interact with and shape data within a single system or across systems (breaking down data silos) and are created here without a dependence on the source systems from which that data originates, as well as the target channels through which that data is delivered.
Experience APIs - Experience APIs are the means by which data can be reconfigured so that it is most easily consumed by its intended audience, all from a common data source, rather than setting up separate point-to-point integrations for each channel. An Experience API is usually created with API-first design principles where the API is designed for the specific user experience in mind.
NEW QUESTION # 146
A RAML specification is defined to manage customers with a unique identifier for each customer record. What URI does MuleSoft recommend to uniquely access the customer identified with the unique ID 1234?
- A. /customers?custid=true&custid=1234
- B. /customers?operation=get&custid=1234
- C. /customers/custid=1234
- D. /customers/1234
Answer: D
Explanation:
URI parameter (Path Param) is basically used to identify a specific resource or resources . For eg : the URL to get employee details on the basis of employeeID will be GET /employees/{employeeID} where employees is resource and {employeeID} is URI parameter. Hence option 1is the correct answer
NEW QUESTION # 147
Refer to the exhibit.
What is a valid expression for the Choice router's when expression to route events to the documenticShipping flow?
- A. 0#[ payload = 'US' ]
- B. #[ if(payload == "US") ]
- C. #[ payload == 'US' J
- D. #[ if(payload ='US') J
Answer: C
Explanation:
Choice Router
The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routingoption. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers thatroute's execution and the others are not checked. If none of the expressions are true, then the default route executes.
Properties of <when>
PropertyDescription
Expression (expression)
Expression in DataWeave language to evaluate input.If the expressionevaluates to true, this routing option is used:
* <whenexpression="#[vars.language == 'Spanish']">
Mulesoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept With respect to above information , Option 1 is the correct syntax as others are incorrect because of below reasons
* Single = is not the correct syntax to validate the condition. It should be ==
* If keyword is not required in when condition.
NEW QUESTION # 148
Refer
to the exhibits. A web client submits a request to http://localhost:8081/fliqhts?destination=SFO and the Web Service Consumer throws a WSC:BAD_REQUEST error.
What is the next stepto fix this error?
- A. set a JSON payload before the Consume operation that contains the destination query parameter
- B. set a property m the Consume operation equal to the destination query parameter
- C. Set a header In the Consume operation equal to the destination query parameter
- D. set a SOAP payload before the Consume operation that contains the destination query parameter
Answer: D
Explanation:
As can be seen in error message , SOAP service findFlights expects the SOAP paylaod. This can be set using transform message processor which forms SOAP payload before the Consume operation that contains the destination query parameter
NEW QUESTION # 149
Where is metadata stored in a Mule project
- A. Config.yaml file
- B. Global Element
- C. POM.xml file
- D. application-types.xml
Answer: D
Explanation:
Metadata is stored in application-types.xml flle located under src/main/resources.
Mule 4 applications contain an application-types.xml file, which is where metadata around your data types is stored. For example, if you create a new CSV type, that metadata will be added to this file. This new file is easy to share, commit, and merge when conflicts arise, which enables you to do more metadata-driven development.
