  INFO 2021-06-09 19:15:02,486 [[MuleRuntime].uber.06: [validationtest].batch-job- validationtestBatch_Job-work-manager @6de10f3e] [processor:

  org.mule.runtime.core.internal.processor.LoggerMessageProcessor: [ "\"E\""

  ]

  Batch aggregator value is 3. Hence in first time it will print ["A", "C", "D"] and in next iteration it will print [ "E" ]

• Question 179:

  How can you call a subflow from Dataweave?

  A. Not possible in Mule 4
  B. Import function
  C. Lookup function
  D. Include function
  C. Lookup function

  ---

  Explanation

  This is a trick question.

  You can call only flows from DataWeave using lookup function. Note that lookup function does not support calling subflows.

  A subflow needs a parent context to inherit behaviors from such as exception handling, which a flow does not need Hence correct answer is Not possible in Mule 4

• Question 180:

  Explanation

  Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a `?' Is added followed immediately by a query parameter. To add multiple parameters, an `and' is added in between each. Hence coming back to question, endpoint would return Patients with name as John and (and is very important here) surname as Bell
