• Question 3:

  Refer to the exhibits.

  The mule application implements a REST API that accepts GET request from two URL's which are as follows

  1) http://acme.com/order/status

  2) http://acme.com/customer/status

  What path value should be set in HTTP listener configuration so that requests can be accepted for both these URL's using a single HTTP listener event source?

  

  A. *[order,customer]/status
  B. ?[order,customer]/status
  C. */status (Correct)
  D. *status
  C. */status (Correct)

• Question 4:

  What of the below is not a feature of API Notebooks?

  A. API documentation
  B. Creates a client for an API
  C. Creates a mock service for an API
  D. Perform authenticated live calls on a real server
  C. Creates a mock service for an API

  ---

  Explanation/Reference:

  Correct answer is Creates a mock service for an API API Notebook is an open source, shareable web application for API documentation, interactive API tutorial and example generatation, and a client for your API endpoints. Using API Notebook, you can make requests and quickly transform the responses into readable format. However it cannot be used to mock service for an API.

• Question 5:

  Refer to the exhibits.

  

  In the Choice router, the When expression for the domesticShipping route is set to "#[payload = 'FR']". What is logged after the Choice router completes?

  A. A string with value "FR"
  B. A DataVVeave syntax error
  C. The result of the intemationalShipping flow
  D. The result of the domesticShipoing flow
  B. A DataVVeave syntax error

• Question 6:

  Refer to the exhibits.

  

  This main mule application calls a separate flow called as ShippingAddress which returns the address corresponding to the name of the user sent to it as input. Output of this ShippingAddress is stored in a target variable named address.

  Next set of requirement is to have a setPayload transformer which will set below two values

  1) orderkey which needs to set to be equal to the order element received in the original request payload.

  2) addressKey which needs to be set to be equal to the address received in response of ShippingAddress flow

  What is the straightforward way to properly configure the Set Payload transformer with the required data?

  

  

  A mule application is being developed which will process POST requests coming from clients containing the name and order information. Sample request is as below

  A. 1. 1. { 2. 2. orderkey: "payload.order", 3. 3. addresskey: "vars.address" 4. 4. }
  B. 1. 1. { 2. 2. orderkey: "attributes.shippingaddress.order", 3. 3. addresskey: "payload" 4. }
  C. 1. 1. { 2. 2. orderkey: "payload.order", 3. 3. addresskey: "address" 4. }
  D. 1. 1. { 2. 2. orderkey: "attributes.order", 3. 3. addresskey: "vars.address" 4. }
  A. 1. 1. { 2. 2. orderkey: "payload.order", 3. 3. addresskey: "vars.address" 4. 4. }

  ---

  Explanation/Reference:

  Correct answer is as below. In this case address will be stored in a variable. Hence payload will not be overwritten and will contain order details { orderkey: "payload.order",

  addresskey: "vars.address"

  }

• Question 7:

  Refer to the exhibit.

  

  What should be changed to fix the 415 error?

  A. set the response Content-Type header to text/plain
  B. set the response Content-Type header to application/json
  C. Set the request Content-Type header to application/] son
  D. set the request Content-Type header to text/plain
  C. Set the request Content-Type header to application/] son

  ---

  Explanation/Reference:

  The HTTP 415 Unsupported Media Type client error response code indicates that the server refuses to accept the request because the payload format is in an unsupported format. The format problem might be due to the request's indicated Content-Type or Content-Encoding , or as a result of inspecting the data directly. In this case as per RAML specification data is expected in application/json and in request Content-Type is set as "text/plain" which is incorrect. Hence solution is set the request Content-Type header to application/json

• Question 8:

  Refer to the exhibit.

  

  The main flow contains a Flow Reference for the child flow.

  What values are accessible in the child flow after a web client submits a request to http://localhost:8Q81/order? color=red?

  A. payload
  B. payload quantity var
  C. payload color query param
  D. payload quantity var color query param
  D. payload quantity var color query param

  ---

  Explanation/Reference:

  Correct answer is payload quantity var color query param

• Question 9:

  Refer to the exhibits.

  

  A web client sends a POST request to the HTTP Listener with the payload "Hello-". What response is returned to the web client? What response is returned to the web client?

  A. Hello- HTTP-] MS2-Three B. HTTP-JMS2-Three
  C. Helb-JMS1-HTTP-JMS2 -Three
  D. Hello-HTTP-Three
  A. Hello- HTTP-] MS2-Three B. HTTP-JMS2-Three

• Question 10:

  In the Database On Table Row operation, what does the Watermark column enable the On Table Row operation to do?

  A. To avoid duplicate processing of records in a database.
  B. To delete the most recent records retrieved from a database to enable database caching
  C. To enable duplicate processing of records in a database
  D. To save the most recent records retrieved from a database to enable database caching
  A. To avoid duplicate processing of records in a database.

  ---

  Explanation/Reference:

  The correct answer is To avoid duplicate processing of records in a database. If a watermark column is provided, the values taken from that column are used to filter the contents of the next poll, so that only rows with a greater watermark value are returned. If an ID column is provided, this component automatically verifies that the same row is not picked twice by concurrent polls.
