increasing numerical column.
How should the listener be configured so it retrieves new rows at most one time?
A.
Set the target tostore the last retrieved record_id value
B.
Set the ObjectStore to store the last retrieved record_id value
C.
Set the target to the record_id column
D.
Set the watermark column to the record id column
Set the watermark column to the record id column

Which one of them is NOT a flow in Mule?
A. sync flow
B. subflow
C. async sub flow
D. async flow
Explanation:
Correct answer is async sub flow. Rest are valid flows in Mule.
Sub flow is always synchronous.
Refer to the exhibits.
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
The original XML payload
According to MuleSoft, what is the Center for Enablement’s role in the new IT operating model?
A. Implements line of business projects to enforce common security requirements
B. Creates and manages discoverable assets to be consumed by line of business developers
C. Centrally manages partners and consultants to implement line of business projects
D. Implements line of business projects to enforce common security requirements
Correct answer is Creates and manages discoverable assets to be consumed by line of
business developers.
C4E does not get directly involved in projects.

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=40}
C. 1.{amount=140}
2.{amount=102}
3.{step2amount=100}
4.{step2amount=140}
D. 1.{amount=140}
2.{amount=102}
3.{step2amount=100}
4.{step2amount=140}
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}
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?
A. 1
B. 2
C. 3
D. 4
Explanation:
In this case three configurations will be required each for port 8000, 6000 and 7000.
There would be three global elements defined for HTTP connections.
Each HTTP connection will have host and port. One example shown below with host as localhost and port 6000.
A web client submits a request tohttp://localhost:8081/books/0471767840. The value
"0471767840" is captured by a Set Variable transformer to a variable named booklSBN.
What is the DataWeave expression to access booklSBN later in the flow?
A.
booklSBN
B.
attributes.booklSBN
C.
flowVars.booklSBN
D.
vars. booklSBN
vars. booklSBN
