Pass the Salesforce Salesforce MuleSoft Salesforce-MuleSoft-Developer-I Questions and answers with CertsForce

This is a trick question.

You can callonly flows from DataWeave using lookup function. Note that lookup function does not support calling subflows.

A subflow needs a parent context to inherit behaviors from such as exception handling, which a flow does not need

Hence correct answer is Not possible in Mule 4

Attributes are replaced with new attributes from the HTTP Request response.

Attributes include everything apart from Payload/body. For ex: Headers, query parameters, URI parameters.

So, when outbound HTTP request is made, new attributes need to passthe outbound HTTP request and old attributes are replaced.

I have created below diagram to make it easy for you to understand:

Error in validation component will get processed by Processer level On Error Propagate block and thenerror will be rethrown which will get processed by flow level error handler which will set payload to "Error- main flow". Hence correct answer is Error - main flow

1) Request is received by HTTP listener

2) Try scope gets executed

3) The validator component in the Try scope creates an Error Object because the payload is not null.

4) The On Error Propagate handles the error. The payload is set to “Error – Try scope”

6) “Error – Try scope” is returned to the 'On Error Continue' block. Main flow execution stops. Payload is set to "Error - main flow"

7) “Error - main flow” is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200

Mule event is correct answer. Mule event has two parts which are as follows

1) Message (which contains payload and attributes like headers and query/uri parameters

2) Variables
