What is the DataWeave expression to access booklSBN later in the flow?

booklSBN

attributes.booklSBN

flowVars.booklSBN

vars. booklSBN

QUESTION 98
Refer to the exhibits.

The two Mule configuration files belong to the same Mule project. Each HTTP Listener is configured with the same host string and the port number, path, and operation values are shown in the display names.
What is the minimum number of global elements that must be defined to support all these HTTP Listeners?

QUESTION 99
Refer to the exhibits.

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 !

QUESTION 100
Refer to the exhibits. In the color flow , both the variable named color and payload are set to “red”.
An HTTP POST request is then sent to the decideColor flow’s HTTP Listener.
What is the payload value at the Logger component after the HTTP request completes?

white

red

blue

Error message

Correct answer is white.
Key thing to note here is that variables are not available to the called flow when it is invoked using HTTP request.
So the flow goes like below
1) Color variable is set to red
2) Payload is set to red
3) Child flow is called using HTTP request which means variables are not available in called flow (They would have been if flow reference activity would have been used)
4) Hence set payload activity will set payload to white as color variable is null
5) Payload returned in main flow is white.
6) So finally output of logger is white

QUESTION 101
Refer to the exhibit.

What should be changed to fix the 415 error?

set the response Content-Type header to text/plain

set the response Content-Type header to application/json

Set the request Content-Type header to application/] son

QUESTION 103
Refer to the exhibit.

This RAML specification includes a resource and method to retrieve accounts by account_type and industry.
What is the correct URI to get all retail finance accounts?

/accounts/account_type=retall/industty=finance

/accounts?account_type:retail&itxJustry:finance

QUESTION 104
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
