A)
B)
C)
D)
- A. Option D
- B. Option A
- C. Option B

"0": {
"attributes": ...,
"payload": "100"
},
"1": {
"attributes": ...,
"payload": "200"
}
}

4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. )}
Answer: A
Explanation:
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 !

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}
4. {step2amount=140} - B. 1. {amount=140}
2. {amount=102}
3. {step2amount=100} - 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: D
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}

NEW QUESTION # 63
Refer to the exhibits.
The Validation component in the Try scope throws an error.
What response message is returned to a client request to the main flow's HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?
- A. Validation Error
- B. Error - main flow
- C. Error - Try scope
- D. Success - main flow
Answer: B
Explanation:
Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow.
Hence correct answer is Success - main flow
1) HTTP listener received request
2) The Flow Reference calls the child flow
3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops
#[error.description] = "payload is not a valid INTEGER value"
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The On Error Continue handles the errorThe payload is set to "Error - Sub Flow"
5) "Error - Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success - Finished Main Flow"
6) "Success - Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200 As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.

NEW QUESTION # 68
In the Database On Table Row operation, what does the Watermark column enable the On Table Row operation to do?
- A. To delete the most recent records retrieved from a database to enable database caching
- B. To avoid duplicate processing of records in a database.
- C. To save the most recent records retrieved from a database to enable database caching
- D. To enable duplicate processing of records in a database
Answer: B
Explanation:
The correct answer is To avoid duplicate processing of records in a database.
If a watermark column is provided, the values taken from that column are used to filter the contents of the next poll, so that only rows with a greater watermark value are returned. If an ID column is provided, this component automatically verifies that the same row is not picked twice by concurrent polls.
