A.
Option A
B.
Option B
C.
Option C
D.
Option D
Option A
Refer to the exhibits.
A. [[5, 10, 15, 20], 1]
B. [[5, 10, 15, 20], 5]
C. [[Req5, Req10, Req15, Req20], 5]
D. [Req5Req10,Req15Req20, 5]
Correct answer is [[5, 10, 15, 20], 5]
Key thing to note here is that any changes made to payload in for each loop are not available outside for each scope where as variable value updated in for each loop is visible
out side for each loop too.
Refer to the payload.
The Set payload transformer sets the payload to an object. The logger component's
message attribute is configured with the string "Result #["INFO"++ payload]"
What is the output of logger when this flow executes?
A. Result INFOpayload
B. Result INFO{"student":{"name":"Anay","age":6}}
C. 1. 1. "You called the function '++' with these arguments:
2. 2. 1: String ("INFO")
3. 3: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age: 6 as
Numbe...)
D. Error : You evaluated inline expression # without ++
Explanation:
Correct answer is as below as concatenation operation works only with string and not with
the objects. In this case payload is object.
"You called the function '++' with these arguments:
1: String ("INFO")
2: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age
A Database On Table Row listener retrieves data from a CUSTOMER table that contains a
primary key userjd column and an increasing kxjin_date_time column. Neither column
allows duplicate values. How should the listener be configured so it retrieves each row at most one time?
A.
Set the watermark column to the bgin_date_time column
B.
Set the target value to the last retrieved login_date_time value
C.
Set the target value to the last retrieved user_jd value
D.
Set the watermark column to the user_Id column
Set the watermark column to the bgin_date_time column
What module and operation will throw an error if a Mule events payload is not number?
A. Filter modules Is Number operation
B. Validation modules Is Number operation
C. Validation modules Is not Number operation
D. None of these
Correct answer is Validation modules Is Number operation.
Mule 4 does not use filters anymore. The functionality provided by filters in Mule 3 can be
achieved by using the Validation Module.
What is the difference between a subflow and a sync flow?
A. No difference
B. Subflow has no error handling of its own and sync flow does
C. Sync flow has no error handling of its own and subflow does
D. Subflow is synchronous and sync flow is asynchronous
Explanation:
Correct answer is Subflow has no error handling implementation where as sync flow has Subflow:
A subflow processes messages synchronously (relative to the flow that triggered its
execution) and always inherits both the processing strategy and exception strategy
employed by the triggering flow. While a subflow is running, processing on the triggering
flow pauses, then resumes only after the subflow completes its processing and hands the
message back to the triggering flow.
Synchronous Flow:
A synchronous flow, like a subflow, processes messages synchronously (relative to the
flow that triggered its execution). While a synchronous flow is running, processing on the
triggering flow pauses, then resumes only after the synchronous flow completes its
processing and hands the message back to the triggering flow. However, unlike a subflow,
this type of flow does not inherit processing or exception strategies from the triggering flow.
This type of flow processes messages along a single thread, which is ideally suited to
transactional processing.
