All three of the conditions for the Choice router are true. What messages are written in the application log?


A. Route1


B. Route2


C. Route1,Route2


D. Route1,Route2,Default





A.
  Route1

Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.

What is written to the records.csv file when the flow executes?


A. The JSON payload


B. An error message


C. Nothing


D. The payload convert to CVS





A.
  The JSON payload

Explanation: Transform Message Add write_date is coverting payload in JSON format and same JSON payload is avaialble to file write processor. However, if the payload is a different format (for example, not CSV) , you can place the transformation inside the Write operation to generate content that will be written without producing a side effect on the message in transit. This is not done in this case. By default, the connector writes whatever is in the message payload. Hence JSON payload will be written to file.
