NEW QUESTION # 108
What happens to the attributes of a Mule event in a flow after an outbound HTTP Request is made?
- A. Attributes are replaced with new attributes from the HTTP Request response (which might be null)
- B. New attributes may be added from the HTTP response headers, but no headers are ever removed
- C. Previous attributes are passed unchanged
- D. Attributes do not change
Answer: A
Explanation:
Attributes are replaced with new attributes from the HTTP Request response.
Attributes include everything apart from Payload/body. For ex: Headers, query parameters, URI parameters.
So, when outbound HTTP request is made, new attributes need to pass the outbound HTTP request and old attributes are replaced.

NEW QUESTION # 109
What is output of Dataweave flatten function?
- A. LInkedHashMap
- B. Object
- C. Array
- D. Map
Answer: C
Explanation:
Correct answer is Array.
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 # 111
A web client submits a request to http://localhost:8081?accountType=personal. The query parameter is captured using a Set Variable transformer to a variable named accountType.
What is the correct DataWeave expression to log accountType?
- A. Account Type: #[vars.accountType]
- B. Account Type: #[message.inboundProperties.accountType]
- C. Account Type: # [attributes.accountType]
- D. Account Type: #[flowVars.accountType]
Answer: A
Explanation:
vars: Keyword for accessing a variable, for example, through a DataWeave expression in a Mule component, such as the Logger, or from an Input or Output parameter of an operation. If the name of your variable is myVar, you can access it like this: vars.myVar Hence correct answer is Account Type: #[vars.accountType]

NEW QUESTION # 114
A Mule application contains a global error handler configured to catch any errors.
Where must the global error handler be specified so that the global error handler catches all errors from flows without their own error handlers?
- A. A global element
- B. Nowhere, the global error handler is automatically used
- C. The pom.xml file

1) Click Global Elements to open Global Configuration Elements. Global Elements is located below the Studio canvas
2) In Global Configuration Elements, click Create to open the Choose Global Type dialog
3) From the dialog, select Global Configuration -> Configuration, and then click OK to open the Configuration dialog.
4) From the select Configuration dialog, select allErrorHandler for the Default Error Handler field, and click OK.

Answer: C
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

NEW QUESTION # 118
Refer to the exhibits.
The Validation component in the Try scope throws an error.
What response message is returned to a client request to the main flow's HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?
- A. Error - main flow
- B. Error - Try scope
- C. Validation Error
- D. Success - main flow
Answer: A
Explanation:
Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow.
Hence correct answer is Success - main flow
1) HTTP listener received request
2) The Flow Reference calls the child flow
3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops
#[error.description] = "payload is not a valid INTEGER value"
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The On Error Continue handles the errorThe payload is set to "Error - Sub Flow"
5) "Error - Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success - Finished Main Flow"
6) "Success - Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200 As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.

NEW QUESTION # 125
A flow needs to combine and return data from two different data sources. It contains a Database SELECT operation followed by an HTTP Request operation.
What is the method to capture both payloads so the payload from the second request does not overwrite that from the first?
- A. Put the Database SELECT operation inside a Cache scope
- B. Put the Database SELECT operation inside a Message Enricher scope
- C. Save the payload from the Database SELECT operation to a variable
- D. Nothing, previous payloads are combined into the next payload
Answer: C
Explanation:
Correct answer is Save the payload from the Database SELECT operation to a variable Response from HTTP request will override the payload and hence response of database SELECT can be lost.
Best way to preserve is to assign payload of first operation to variable using TransformMessage.
