需要定义一个名为 newProdCode 的函数，该函数接受两个输入参数，即 itemID 的整数值和 productCategory 的字符串值，并返回一个新的产品代码。
定义 newProdCode 函数的正确 DataWeave 代码是什么？

fun newProdCode{itemID: Number, productCategory：String) -> "PC-" ++ productCategory ++ (itemID as String)

fun newProdCode(itemID: Number, productCategory: String) = "PC-" ++ productCategory ++ (itemID as String)

function newProdCode(itemID: Number, productCategory: String) =
"PC-" ++ productCategory ++ (itemID as String)

var newProdCode(itemID: Number, productCategory: String) ->
"PC-" ++ productCategory ++ (itemID as String)

Refer to exhibits.

In the execution of the Scatter-Gather , the flow route completes after 10 seconds and the flow2 route completes in 40 seconds. How many seconds does it take for the Scatter-Gather to complete?

Scatter-Gather sends the event to each routes concurrently. Hence both route in this example will start in parallel. So total time to complete processing is 40 seconds which is option 3

Refer to exhibits.

What message should be added to Logger component so that logger prints “The city is Pune” (Double quote should not be part of logged message)?

#[“The city is” ++ payload.City]

The city is + #[payload.City]

The city is #[payload.City]

#[The city is ${payload.City}

Correct answer is The city is #[payload.City]
Answer can get confused with the option #[“The city is” ++ payload.City] But note that this option will not print the space between is and city name. This will print The city isPune

新问题 27
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 configuration properties file

Nowhere, the global error handler is automatically used

A global element

The pom.xml file

Correct answer is A global element
Global error handlers are to be created in global element .
Quick note to remember here is Global error handlers come in to picture only when there are no error handlers specified as flow level.
Steps to create Global error handler
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.

Scatter-Gather sends the event to each routes concurrently and returns a collection of all results. Collection is an Object of Objects. Each object contains attributes and payload from each Mule event returned from a flow. Hence option 4 is the correct answer.

An organization is beginning to follow Mulesoft’s recommended API led connectivity approach to use modern API to support the development and lifecycle of the integration solutions and to close the IT delivery gap.
What distinguishes between how modern API’s are organized in a MuleSoft recommended API-led connectivity approach as compared to other common enterprise integration solutions?

The API interfaces are specified as macroservices with one API representing all the business logic of an existing and proven end to end solution

The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes

The API implementation are built with standards using common lifecycle and centralized configuration management tools

The APIO implementations are monitored with common tools, centralized monitoring and security systems

Correct answer is The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes

The Batch Job scope contains two Batch Steps scopes with different accept expression.
The input payload is passed to the Batch Job scope.
After the entire payload is processed by the batch job scope , what messages have been logged by the Logger component?

1. {amount=140}
2. {amount=102}
3. {step2amount=100}

1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=40}

1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140}

5. {step2amount=102}
解释：
Lets understand this solution step by step.
1) Batch Step (Less than 50)
Accept expression for this batch step is less than 50. Hence elements which will go in this batch step are amount value 40 and 2. Hence output of logger in first batch step is
{amount=140}
{amount=102}
2) Batch Step (Greater than 20)
Accept condition for this batch step is greater than 20. Note that input amount values for this batch step are 100 , 140 and 102 (last two values have been updated in batch step less than 50) As all values satisfy this condition out put of second logger is
{step2amount=100}
{step2amount=140}
{step2amount=102}
Hence correct answer to this question is

{amount=140}
{amount=102}
{step2amount=100}
{step2amount=140}
{step2amount=102}

What DataWeave expression transforms the conductorIds array to the XML output?

1. 1. trains:
2. 2. conductorIds map ((engId, index) ->
3. 3. train: {
4. 4. engineerId: engId
5. 5. }
6. 6. )

1. 1. { trains:
2. 2.
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. }

1. 1. trains:
2. 2. {(
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. )}

1. 1. {( trains:
2. 2.
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. )}

Points to remember:
* XML must have a root element.
* XML only allows one root element
* To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output
* When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}
-{ } are defining the object
( ) are transforming each element in the array as a key/value pair
* The transformation to XML would fail if the above mentioned considerations were not taken into account.
* Thus the transformation script declares a root element as trains and wraps the data in “{( )}”.
Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.
I call this a “Wrap The Map” scenario. Hope it would help you remember !
