QUESTION: 73

Refer to the exhibits.

This main mule application calls a separate flow called as ShippingAddress which returns the address corresponding to the name of the user sent to it as input. Output of this ShippingAddress is stored in a target variable named address.

Next set of requirement is to have a setPayload transformer which will set below two values:

1) orderkey which needs to set to be equal to the order element received in the original request payload.

2) addressKey which needs to be set to be equal to the address received in response
of ShippingAddress flow.

What is the straightforward way to properly configure the Set Payload transformer with the required data?

A mule application is being developed which will process POST requests coming from clients containing the name and order information. Sample request is as below

1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "vars.address"
4. 4. }
1. 1. {
2. 2. orderkey: "attributes.shippingaddress.order",
3. 3. addresskey: "payload"
4. }
1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "address"
4. }
1. 1. {
2. 2. orderkey: "attributes.order",
3. 3. addresskey: "vars.address"
4. }

Answer(s): A

Explanation:

Correct answer is as below. In this case address will be stored in a variable. Hence payload will not be overwritten and will contain order details {
orderkey: "payload.order",
addresskey: "vars.address"
}

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
