• Question 231:

  What is the difference between a subflow and a sync flow?

  A. No difference
  B. Subflow has no error handling of its own and sync flow does
  C. Sync flow has no error handling of its own and subflow does
  D. Subflow is synchronous and sync flow is asynchronous
  B. Subflow has no error handling of its own and sync flow does

  ---

  Explanation/Reference:

  Correct answer is Subflow has no error handling implementation where as sync flow has. Subflow A subflow processes messages synchronously (relative to the flow that triggered its execution) and always inherits both the processing strategy and exception strategy employed by the triggering flow. While a subflow is running, processing on the triggering flow pauses, then resumes only after the subflow completes its processing and hands the message back to the triggering flow. Synchronous Flow A synchronous flow, like a subflow, processes messages synchronously (relative to the flow that triggered its execution). While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow. However, unlike a subflow, this type of flow does not inherit processing or exception strategies from the triggering flow. This type of flow processes messages along a single thread, which is ideally suited to transactional processing

• Question 232:

  As a part of requirement , application property defined below needs to be accessed as dataweave expression. What is the correct expression to map it to port value?

  A. { port : p('db.port')}
  B. { port : {db:port}}
  C. { port : p['db.port']}
  D. Application property cannot be accessed in Dataweave
  A. { port : p('db.port')}

  Explanation/Reference:

  Option 1 is the correct syntax

• Question 233:

  What is the purpose of the api:router element in APIkit?

  A. Creates native connectors using a 3rd party Java library
  B. Serves as an API implementation
  C. Validates requests against RAML API specifications and routes them to API implementations
  D. Validates responses returned from API requests and routes them back to the caller
  C. Validates requests against RAML API specifications and routes them to API implementations

  ---

  Explanation/Reference:

  The APIkit Router is a key message processor that validates requests against the provided definition, enriches messages (for example by adding default values to the messages) and routes requests to a particular flow. Also, the Router raises errors messages if errors occurs while routing, validating or processing the user request.

• Question 234:

  What is the main purpose of flow designer in Design Center?

  A. To design and develop fully functional Mule applications in a hosted development environment
  B. To design API RAML files in a graphical way
  C. To design and mock Mule application templates that must be implemented using Anypoint Studio
  D. To define API lifecycle management in a graphical way
  A. To design and develop fully functional Mule applications in a hosted development environment

  ---

  Explanation/Reference:

  Its primary function is to design and develop fully functional Mule applications in a hosted development environment.
