  2. [''E'']
  3. [''D", "E"]
  4. [ "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\""
]
---
INFO 2021-06-09 19:15:02,486 [[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: [ "\"E\""
]
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" ]



Refer to the exhibit. The input array of strings is passed to the batch job, which does NOT do any filtering or aggregating.

What response message is returned to the web client?

  1. ""
  2. "End"
  3. "Start"
  4. "String is not blank"

Answer(s): B

3. Default Error Handler catches and Propagates error
4. 'On Error Propogate' is 'RED IN RED OUT'. It Returns Status Code : 500 & #[error.description] --------------------------------------------------------------------------------------------------------------------------

Correct answer is String is not blank. Because validation component will throw an error as payload is not blank.
