Question

What is the response to a web client's request to http://localhost:8081?

Answer

A) After
B) Before
C) Validation Error
D) null

The correct answer to this question is C.

Explanation

This question is tricky, because the answer is not visible in the visual flow, but in the XML code.

As we can see in the code, if the payload is null, the flow will continue on the next component. If not, the "Validator" component is going to write "Validation Error" into the payload.

Since the payload is set in the first "Set Payload" component, it is not null anymore and it is going to be changed by the "Validator" component.
