Refer to the exhibits. In the color flow , both the variable named color and payload are set to "red".
An HTTP POST request is then sent to the decideColor flow's HTTP Listener.
What is the payload value at the Logger component after the HTTP request completes?
- A. white
- B. blue
- C. Error message
- D. red
正解：A
解説：
Correct answer is white.
Key thing to note here is that variables are not available to the called flow when it is invoked using HTTP request.
So the flow goes like below
1) Color variable is set to red
2) Payload is set to red
3) Child flow is called using HTTP request which means variables are not available in called flow (They would have been if flow reference activity would have been used)
4) Hence set payload activity will set payload to white as color variable is null
5) Payload returned in main flow is white.
6) So finally output of logger is white

A Batch Job scope has five batch steps. An event processor throws an error in the second batch step because the input data is incomplete. What is the default behavior of the batch job after the error is thrown?
- A. Error is ignored
- B. All processing of the batch job stops.
- C. Batch is retried
- D. Event processing continues to the next batch step.
正解：B
解説：
In case of an error , batch job completes in flight steps and stops further processing.
MuleSoft Doc Ref : Handling Errors During Batch Job | MuleSoft Documentation The default is all processing will stop but we can change it by Max Failed Record field.
General -> Max Failed Records: Mule has three options for handling a record-level error: Finish processing, Continue processing and Continue processing until the batch job accumulates a maximum number of failed records. This behavior can be controlled by Max Failed Records.
The default value is Zero which corresponds to Finish processing.
The value -1, corresponds to Continue processing.
The value +ve integer, corresponds to Continue processing until the batch job accumulates a maximum number of failed records
