QUESTION: 93

Refer to the exhibits.

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

Answer(s): D

Explanation:

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}

QUESTION: 94

A Mule flow has three Set Variable transformers. What global data structure can be used to access the variables?

Mule event attributes
Mule event message
Mule application properties
Mule event

Answer(s): D

Explanation:

Mule event is correct answer. Mule event has two parts which are as follows
1) Message (which contains payload and attributes like headers and query/uri parameters
2) Variables

QUESTION: 95

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

Answer(s): C

Explanation:

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
