• Question 126:

  What is output of Dataweave flatten function?

  A. Object
  B. Map
  C. Array
  D. LInkedHashMap
  C. Array

  ---

  Explanation/Reference:

  Correct answer is Array.

  Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [ 1, 2, 3, 4, 5, [6], null ]). This example defines three arrays of numbers, creates another array containing those three arrays, and then

  uses the flatten function to convert the array of arrays into a single array with all values.

  Source

  %dw 2.0

  output application/json

  var array1 = [1,2,3]

  var array2 = [4,5,6]

  var array3 = [7,8,9]

  var arrayOfArrays = [array1, array2, array3]

  flatten(arrayOfArrays) Output [ 1,2,3,4,5,6,7,8,9 ]

• Question 127:

  Refer to the exhibits.

  

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

  A. End
  B. String is not blank
  C. No response would be sent back to client and request will get errored out in Mule
  D. Start
  B. String is not blank

  ---

  Explanation/Reference:

  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 Reference Diagram:

  

• Question 128:

  What is the trait name you would use for specifying client credentials in RAML?

  A. headers
  B. client-id
  C. client-id-required
  D. cannot be specified in RAML
  C. client-id-required

  ---

  Explanation/Reference:

  client-id-required enforces clients to add client_id and client_secret.

  Please refer to below steps.

  Add a section called traits: at the root level to define query parameters:

  traits:

  -client-id-required:

  queryParameters:

  client_id:

  type: string

  client_secret:

  type: string

  2) Reference the trait in each of the methods to specify that each of the methods require these query parameters. After each method in the RAML file, add is:

  [client-id-required]. For example:

  /users:

  get:

  is: [client-id-required]

  description: Gets a list of JSONPlaceholder users.
