What is output of Dataweave flatten function?
- A. Map
- B. Array
- C. Object
- D. LInkedHashMap
Answer: B
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 ]

Each route in the Scatter-Gather sets the payload to the number shown in the label. What response is returned to a web client request to the HTTP Listener?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
Correct answer is as below.
After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.
{
"0": {
"attributes": ...,
"payload": "100"
},
"1": {
"attributes": ...,
"payload": "200"
}
}

NEW QUESTION # 109
Refer to the exhibits.
A web client submits a request to http://localhQst:8081. What is the structure of the payload at the end of the flow?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Scatter-Gather Router
The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.

NEW QUESTION # 113
A Database On Table Row listener retrieves data from a CUSTOMER table that contains a primary key userjd column and an increasing kxjin_date_time column. Neither column allows duplicate values.
How should the listener be configured so it retrieves each row at most one time?
- A. Set the target value to the last retrieved user_jd value
- B. Set the watermark column to the bgin_date_time column
- C. Set the watermark column to the user_Id column
- D. Set the target value to the last retrieved login_date_time value
Answer: B
Explanation:
* Watermark allows the poll scope to poll for new resources instead of getting the same resource over and over again.
* The database table must be ordered so that the "watermark functionality" can move effectively in the ordered list. Watermark stores the current/last picked up "record id."
* If the Mule application is shut down, it will store the last picked up "record id" in the Java Object Store and the data will continue to exist in the file. This watermark functionality is valuable and enables developers to have increased transparency.
* Developers do not need to create code to handle caching; it is all configurable!
* There are two columns and both are unique but user_id can't guaranty sequence whereas date_time will always be in increasing order and table content can easily be ordered on the basis of last processed date_time.
So correct answer is: Set the watermark column to the date_time column
NEW QUESTION # 114
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?
- A. Select only Attach Project Sources only
- B. Select the Include project modules and dependencies option only
- C. Select both Attach Project Sources and Include project modules and dependencies option
- D. De-select both Attach Project Sources and Include project modules and dependencies option
Answer: A
Explanation:
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

NEW QUESTION # 116
Refer to the exhibits.
This main mule application calls a separate flow called as ShippingAddress which returns the address corresponding to the name of the user sent to it as input. Output of this ShippingAddress is stored in a target variable named address.
Next set of requirement is to have a setPayload transformer which will set below two values
1) orderkey which needs to set to be equal to the order element received in the original request payload.
2) addressKey which needs to be set to be equal to the address received in response of ShippingAddress flow What is the straightforward way to properly configure the Set Payload transformer with the required data?
A mule application is being developed which will process POST requests coming from clients containing the name and order information. Sample request is as below
- A. 1. 1. {
2. 2. orderkey: "attributes.shippingaddress.order",
3. 3. addresskey: "payload"
4. } - B. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "address"
4. } - C. 1. 1. {
2. 2. orderkey: "attributes.order",
3. 3. addresskey: "vars.address"
4. } - D. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "vars.address"
4. 4. }
Answer: D
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"
}
NEW QUESTION # 117
An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy.
What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?
- A. Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager
- B. Upload the Mule application's JAR file to the API instance in API Manager
- C. Modify the API implementation to use auto-discovery to register with API Manager
- D. Register the same API implementation in Runtime Manager to connect to API Manager
Answer: C
Explanation:
Correct answer is Modify the API implementation to use auto-discovery to register with API Manager API Autodiscovery Configuring autodiscovery allows a deployed Mule runtime engine (Mule) application to connect with API Manager to download and manage policies and to generate analytics data. Additionally, with autodiscovery, you can configure your Mule applications to act as their own API proxy.
When autodiscovery is correctly configured in your Mule application, you can say that your application's API is tracked by (green dot) or paired to API Manager. You can associate an API in a Mule setup with only one autodiscovery instance at a given time.
