• Question 5:

  Refer to the exhibits. A database Address table contains a ZIPCODE column and an increasing ID column. The Address table currently contains four (4) records. The On Table Row Database listener is configured with its watermark set to the Address table's ZIPCODE column and then the Mule application is run in Anypoint Studio for the first time, and the On Table Row Database listener polls the Address table.

  

  A new row is added to the database with ID=5 and ZIPCODE=90006, and then the On Table Row Database listener polls the database again.

  After the next execution of the On Table Row Database listener polling, what database rows have been processed by the Mule flow since the Mule application was started?

  A. ID ZIPCODE 1 90001 2 90005 3 90009 4 90001
  B. ID ZIPCODE 1 90001 2 90005 3 90009 4 90001 5 90006

• Question 9:

  There are three routes configured for Scatter-Gather and incoming event has a payload is an Array of three objects. How routing will take place in this scenario?

  A. Incoming array objects would be split into three and each part would be sent to one route each in sequential manner
  B. Incoming array objects would be split into three and each part would be sent to one route each in parallel
  C. Entire event would be sent to each route sequentially
  D. Entire event would be sent to each route in parallel
  D. Entire event would be sent to each route in parallel

  ---

  explanation:

  Explanation/Reference:

  Entire event would be sent to each route in parallel. Scatter-Gather works as follows :

  -

  The Scatter-Gather component receives a Mule event and sends a reference of this Mule event to each processing route.

  -

  Each of the processing routes starts executing in parallel. After all processors inside a route finish processing, the route returns a Mule event, which can be either the same Mule event without modifications or a new Mule event created by the processors in the route as a result of the modifications applied.

  -

  After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.

  

• Question 10:

  Refer to the exhibits.

  

  A web client sends a POST request with the payload {"oid": "1000", "itemid": "AC200", "qty": "4" } to the Mule application. The File Write operation throws a FILE:CONNECTIVITY error.

  What response message is returned to the web client?

  A. `'FILE:CONNECnvnY'
  B. "ORDER:NOT_CREATED"
  C. "OTHER ERROR"
  D. "File written"
