Question 1

Refer to the exhibits.

The mule application implements a REST API that accepts GET request from two URL's which are as follows

1) http://acme.com/order/status

2) http://acme.com/customer/status

What path value should be set in HTTP listener configuration so that requests can be accepted for both these URL's using a single HTTP listener event source?

A*[order,customer]/status

B?[order,customer]/status

C*/status

D*status

Answer : C

Correct answer is */status as it is the correct way to use wildcards while configuring path value in HTTP listener

Question 2

Refer to the exhibits.

A web client submits the request to the HTTP Listener. What response message would be returned to web client?

AEnd

BString is not blank

CNo response would be sent back to client and request will get errored out in Mule

DStart

Answer : B

Correct answer is String is not blank.

-------------------------------------------------------------------------------------------------------------------------------------------------

Here's specifically what is happening here:

1) Payload is successfully set to ''Start''

2) The Is Blank String validator creates an Error Object because the payload is string 'Start'. Execution stops

#[error.description] = ''String is not blank''

3) Because no error handler is defined, the Mule default error handler handles the error. Remember, at its heart, the Mule Default Error handler is an error handling scope with just an on error propagate

4) ''String is not blank'' is the error message returned to the requestor in the body of the HTTP requestHTTP Status Code: 500
