QUESTION: 66

What is the difference between a subflow and a sync flow?

No difference
Subflow has no error handling of its own and sync flow does
Sync flow has no error handling of its own and subflow does
Subflow is synchronous and sync flow is asynchronous

Answer(s): B

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.

QUESTION: 67

Refer to the exhibits.

The input array of strings is processed by the batch job that processes, filters, and aggregates the values. What is the last message logged by the Logger component after the batch job completes processing?

[ ["A", "C", "D" ], ["E"] ]
[''E'']
[''D", "E"]
[ "A", "C, "D", "E" ]

Answer(s): B

Explanation:

Logs would look like:
INFO 2021-06-09 19:14:56,039 [[MuleRuntime].uber.06: [validationtest].batch-job- validationtestBatch_Job-work-manager @6de10f3e] [processor:
validationtestFlow/processors/1/route/0/route/0/aggregator/processors/0; event: bfb751e1- 9939-11eb-9f69-02053763653a]
org.mule.runtime.core.internal.processor.LoggerMessageProcessor:
[
"\"A\"",
"\"C\"",
"\"D\""
]

]
Batch aggregator value is 3. Hence in first time it will print ["A", "C", "D"] and in next iteration it will print [ "E" ]
-------------------------------------------------------------------------------------------------------------------------
Correct answer is [ "E" ]

QUESTION: 68

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?

Success - main flow
Error - main flow
Error - Try scope
Validation Error

Answer(s): A

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.
