In the requestFlow an HTTP Request operation is configured to send an HTTP request with
an XML payload. The request is sent to the HTTP Listener in the transform Flow.
That flow transforms the incoming payload into JSON format and returns the response to
the HTTP request. The response of the request is storedin a target variable named the
Result.
What is the payload at the Logger component after the HTTP Request?

A.

A non-empty Java object

B.

The original XML payload

C.

null

D.

The returned JSON response

B.

The original XML payload

6. 6. }
7. 7. )
8. 8. )}

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

C. 1. 1. trains:
2. 2. {(
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {

8. 8. )}

Explanation:
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 !
