  A. After
  B. null
  C. Before
  D. Validation error
  D. Validation error

  ---

  Explanation

  Here's specifically what is happening here:

  1) Payload is successfully set to "Before"

  2) Is null validation is used which will pass the message only if payload is null. In this case as payload is not null, it creates an Error Object. Flow execution stops #[error.description] = "Validation error"

  3) Because no error handler is defined, the Mule default error handler handles the error

  4) "Validation error" is the error message returned to the requestor in the body of the HTTP request with HTTP Status Code: 500 Reference diagram:

  What is a valid expression for the Choice router's when expression to route events to the documenticShipping flow?

  A. 0#[ payload = 'US' ]
  B. #[ payload == 'US' J
  C. #[ if(payload = 'US') J
  D. #[ if(payload == "US") ]
  B. #[ payload == 'US' J

  ---

  Explanation

  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.

  Mulesoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept With respect to above information ,

  Option 1 is the correct syntax as others are incorrect because of below reasons

  * Single = is not the correct syntax to validate the condition. It should be == * If keyword is not required in when condition.

• Question 135:

  What happens to the attributes of a Mule event in a flow after an outbound HTTP Request is made?

  A. Attributes are replaced with new attributes from the HTTP Request response (which might be null)
  B. New attributes may be added from the HTTP response headers, but no headers are ever removed
  C. Attributes do not change
  D. Previous attributes are passed unchanged
  A. Attributes are replaced with new attributes from the HTTP Request response (which might be null)

  ---

  Explanation

  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 pass the outbound HTTP request and old attributes are replaced.
