NEW QUESTION # 123
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?
- A. 1. {amount=140}
2. {amount=102}
3. {step2amount=100} - B. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140} - C. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=40} - D. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140}
Answer: B
Explanation:
5. {step2amount=102}
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}

MuleSoft Doc Ref : https://docs.mulesoft.com/runtime-manager/cloudhub-architecture#cloudhub-workers CloudHub Workers Workers are dedicated instances of Mule runtime engine that run your integration applications on CloudHub. The memory capacity and processing power of a worker depends on how you configure it at the application level.
Worker sizes have different compute, memory, and storage capacities. You can scale workers vertically by selecting one of the available worker sizes:

NEW QUESTION # 133
Refer to the exhibits.
A web client sends a POST request with the payload {"oid": "1000", "itemid": "AC200", "qty": "4" } to the Mule application. The File Write operation throws a FILE:CONNECTIVITY error.
What response message is returned to the web client?

NEW QUESTION # 134
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?
- A. Error message
- B. red
- C. white
- D. blue
Answer: 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
NEW QUESTION # 135
How can you call a subflow from Dataweave?
- A. Not possible in Mule 4
- B. Lookup function
- C. Import function
- D. Include function
Answer: B
Explanation:
This is a trick question.
You can call only flows from DataWeave using lookup function. Note that lookup function does not support calling subflows.
A subflow needs a parent context to inherit behaviors from such as exception handling, which a flow does not need Hence correct answer is Not possible in Mule 4
NEW QUESTION # 136
A flow needs to combine and return data from two different data sources. It contains a Database SELECT operation followed by an HTTP Request operation.
What is the method to capture both payloads so the payload from the second request does not overwrite that from the first?
- A. Put the Database SELECT operation inside a Message Enricher scope
- B. Nothing, previous payloads are combined into the next payload
- C. Save the payload from the Database SELECT operation to a variable
- D. Put the Database SELECT operation inside a Cache scope
Answer: C
Explanation:
Correct answer is Save the payload from the Database SELECT operation to a variable Response from HTTP request will override the payload and hence response of database SELECT can be lost.
Best way to preserve is to assign payload of first operation to variable using TransformMessage.
