QUESTION 125
What should this endpoint return? http://dev.acme.com/api/patients?name=John&surname=Bell

Patient with name as John

Patient with surname as bell

Patients with either name as John or surname as Bell

Patients with name as John and surname as Bell

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

QUESTION 132
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?

Process layer

System layer

Experience layer

Data layer

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.

QUESTION 133
An HTTP Request operation sends an HTTP request with a non-empty JSON object payload to an external HTTP endpoint. The response from the external HTTP endpoint returns an XML body. The result is stored in a target named the Result.
What is the payload at the event processor after the HTTP Request?

The XML response body

A non-empty Java object

The original JSON request body

null

QUESTION 134
To avoid hard-coding values, a flow uses some property placeholders and the corresponding values are stored in a configuration file.
Where does the configuration file’s location need to be specified in the Mule application?

The pom.xml file

A global element

The mule-art if act .json file

a flow attribute

Correct answer is A global element
When we create a configuration file , that file needs to added as Global Configuration file in Global element. A global element is a reusable object containing parameters that any number of elements in a flow can share. You reference a global element from Anypoint Connectors or components in your Mule application

QUESTION 135

QUESTION 136
Refer to the exhibits.

All three of the conditions for the Choice router are true. What messages are written in the application log?

Route1

Route2

Route1,Route2

Route1,Route2,Default

Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept 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 routing option. 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 that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.

QUESTION 137
Mule application contains ActiveMQ JMS dependency. Mule application was compiled and run successfully in Anypoint Studio. The mule application must now be exported from Anypoint Studio and shared with other developer. What export options should be selected to create the smallest JAR file that can be imported into other developer’s Anypoint Studio and run successfully?

Select only Attach Project Sources only

Select both Attach Project Sources and Include project modules and dependencies option

Select the Include project modules and dependencies option only

De-select both Attach Project Sources and Include project modules and dependencies option

Correct answer is Select only Attach Project Sources only
You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace.
Deselect the Include project modules and dependencies option.
This option skips bundling the actual modules and external dependencies required to run the Mule application in a Mule runtime engine, creating a lightweight JAR file package that does not include any dependencies specified in the Mule application’s pom.xml file.
The generated JAR file is not a functional deployable archive and cannot be deployed to a Mule runtime engine, but instead offers a way to archive only the source files that make up the Mule application. This is the same as using the -lightWeightPackage flag when packaging using the Mule Maven Plugin and is useful if you want to distribute your project to other Studio installations because it only keeps a reference to all its dependencies. When you import a lightweight package into Studio, all your dependencies are automatically downloaded MuleSoft Doc Ref : https://docs.mulesoft.com/studio/7.8/import-export-packages

QUESTION 138
Refer to the exhibits.

The Validation component in the private flow throws an error. What response message is returned to a client request to the main flow’s HTTP Listener?

Error – private flow

Error – main flow

Success – main flow

Validation Error

QUESTION 139
Refer to the exhibit.

The main flow is configured with their error handlers. A web client submit a request to the HTTP Listener and the HTTP Request throws an HTTP:NOT_FOUND error.
What response message is returned?”
What response message is returned?

APP: API RESOURCE NOT FOUND

HTTP: NOT FOUND

other error

success – main flow

Correct answer is APP: API RESOURCE NOT FOUND
—————————————————————————————————————————————————
1) A web client submits the request to the HTTP Listener.
2) The HTTP Request throws an “HTTP:NOT_FOUND” error, execution halts.
3) The On Error Propagate error Handler handles the error. In this case ,HTTP:NOT_FOUND error is mapped to custom error APP:API_RESOURCE_NOT_FOUND. This error processor sets payload to APP:API_RESOURCE_NOT_FOUND.
4) “APP:API_RESOURCE_NOT_FOUND. ” is the error message returned to the requestor in the body of the HTTP request with HTTP Status Code: 500 Reference Diagram:
