Refer to the exhibits. The main flow contains an HTTP Request in the middle of the flow. The HTTP Listeners and HTTP Requestuse default configurations.
A web client submits a request to the main flow's HTTP Listener that includes query parameters for the pedigree of the piano.
What values are accessible to the Logger component at the end of the main flow?
- A. payloadproducer var
- B. payloadpedigree query params
- C. payload
- D. payloadpedigree query params producer var
Answer: A
Explanation:
In this case as outbound call is made using HTTP: POST /child , all attributes will be replaced by this invocation. Hence query parameter will not be accessible at logger. Hence correct answer is option 2

Refer to the exhibit.
The API needs to beupdated using the company-wide standard for the Plan data type. The Object data type has already been published in Anypoint Exchange with the global reference . ACME/DataTypes
/PlanDataType.raml.
What is a valid RAML specification that reuses the Plan data type?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
As can be seen in RAML, POST expects input in application/json format which eliminates two of the options as two options are in xml format.
Now out of the two remainingoptions, one has id field in request which is only mentioned for get response and not for POST request. Hence id field is not expected in POST request.
Hence correct answer is
{
"name": "GoerdiLa Forge",
"address": "1 Westland CA",
"customer_since":"2014-01-04",
"balance": "4829.29",
"bank_agend_id": "12556"
}

NEW QUESTION # 116
What is output of Dataweave flatten function?
- A. Object
- B. LInkedHashMap
- C. Array
- D. Map
Answer: C
Explanation:
Correct answer isArray.
Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [
1, 2, 3, 4, 5, [6], null ]).
This example defines three arrays of numbers, creates another array containing those three arrays, and then uses the flatten function to convert the array of arrays into a single array with all values.
Source
%dw 2.0
output application/json
var array1 = [1,2,3]
var array2 = [4,5,6]
var array3 = [7,8,9]
var arrayOfArrays = [array1, array2, array3]
---
flatten(arrayOfArrays)
Output
[ 1,2,3,4,5,6,7,8,9 ]
NEW QUESTION # 117
Refer to the exhibits.
A web client submits the request to the HTTPListener. What response message would be returned to web client?
- A. String is not blank
- B. End
- C. Start
- D. No response would be sent back to client and request will get errored out in Mule
Answer: A
Explanation:
Correct answer is String is not blank.
---------------------------------------------------------------------------------------------------------------------------------------- Here's specifically what is happening here:
1) Payload is successfully set to "Start"
2) The Is Blank String validator createsan Error Object because the payload is string "Start". Execution stops
#[error.description] = "String is not blank"
3) Because no error handler is defined, the Mule default error handler handles the error. Remember, at its heart, the Mule Default Error handler is an error handling scope with just an on error propagate
4) "String is not blank" is the error message returned to the requestor in the body of the HTTP requestHTTP Status Code: 500 Reference Diagram:

What is a valid expression for the Choice router's when expression to route events to the documenticShipping flow?
- A. #[ if(payload == "US") ]
- B. #[ if(payload ='US') J
- C. 0#[ payload = 'US' ]
- D. #[ payload == 'US' J
Answer: D
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.

The Validation component in the private flow throws an error. What response message is returnedto a client request to the main flow's HTTP Listener?
- A. Error - main flow
- B. Error - private flow
- C. Validation Error
- D. Success - main flow
Answer: A
Explanation:
Error in validation component will get processed by Processer level On Error Propagate block and thenerror will be rethrown which will get processed by flow level error handler which will set payload to "Error- main flow". Hence correct answer is Error - main flow
1) Request is received by HTTP listener
2) Try scope gets executed
3) The validator component in the Try scope creates an Error Object because the payload is not null.
4) The On Error Propagate handles the error. The payload is set to "Error - Try scope"
6) "Error - Try scope" is returned to the 'On Error Continue' block. Main flow execution stops. Payload is set to "Error - main flow"
7) "Error - main flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200
