Mulesoft MCD-LEVEL1 Online Questions & Answers

• Question 191:

  Refer to the exhibits. A web client sends a POST request to the HTTP Listener and the Validation component in the Try scope throws an error.

  What response message is returned to the web client?

  

  A. Validation Error
  B. "END"
  C. "ERROR1"
  D. ''ERROR2"
  D. ''ERROR2"

  ---

  Explanation/Reference:

  The answer should be Error2. When the error is getting rethrown due to on error propagate, it will be captured in on error continue and hence the answer is Error2. In case, if there is NO on error continue exception handling, the error will be validation error.

• Question 192:

  What module and operation will throw an error if a Mule events payload is not number ?

  A. Filter modules Is Number operation
  B. Validation modules Is Number operation
  C. Validation modules Is not Number operation
  D. None of these
  B. Validation modules Is Number operation

  ---

  Explanation/Reference:

  Correct answer is Validation modules Is Number operation.

  Mule 4 does not use filters anymore. The functionality provided by filters in Mule 3 can be achieved by using the Validation Module.

• Question 193:

  Refer to the exhibits.

  

  What payload and variable are logged at the end of the main flow?

  

  A. [[5, 10, 15, 20], 1]
  B. [[5, 10, 15, 20], 5]
  C. [[Req5, Req10, Req15, Req20], 5]
  D. [Req5Req10,Req15Req20, 5]
  B. [[5, 10, 15, 20], 5]

  ---

  Explanation/Reference:

  Correct answer is [[5, 10, 15, 20], 5]

  Key thing to note here is that any changes made to payload in for each loop are not available outside for each scope where as variable value updated in for each loop is visible out side for each loop too.

• Question 194:

  Refer to the exhibits.

  

  The main flow contains an HTTP Request. The HTTP Listeners and HTTP Request use default configurations.

  What values are accessible in the child flow after a web client submits a request to http://localhost:8081/order? col or = red?

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

• Question 195:

  Where is metadata stored in a Mule project

  A. Config.yaml file
  B. POM.xml file
  C. application-types.xml
  D. Global Element
  C. application-types.xml

  ---

  Explanation/Reference:

  Metadata is stored in application-types.xml flle located under src/main/resources. Mule 4 applications contain an application-types.xml file, which is where metadata around your data types is stored. For example, if you create a new CSV type,

  that metadata will be added to this file. This new file is easy to share, commit, and merge when conflicts arise, which enables you to do more metadata-driven development.

• Question 196:

  Refer to the exhibits. What payload is logged at the end of the main flow?

  

  A. [order1, order2, order3, order4]
  B. [1, 2, 3, 4]
  C. order4
  D. order1order2order3order4
  B. [1, 2, 3, 4]

  ---

  Explanation/Reference:

  This is a trick question. For Each does not modify the current payload. The output payload is the same as the input. Hence output of logger is the same payload which is set before invoking For Each scope. Hence option 2 is correct answer.

• Question 197:

  A web client sends a request to http;//localhost:8081?dept=sales. What is the correct DataWeave expression to access the value of dept?

  A. attributes.queryParams.dept
  B. attributes.dept
  C. message.queryParams.dept
  D. vars.dept
  A. attributes.queryParams.dept

• Question 198:

  Refer to the exhibits.

  A web client sends sale data in a POST request to the Mule application. The Transform Message component then enrich the payload by prepending a vendor name to the sale data.

  What is written to the sales.csv file when the flow executes?

  

  A. The enriched payload in JSON format
  B. The enriched payload in XML format
  C. The enriched payload in CSV format
  D. An error message
  A. The enriched payload in JSON format

• Question 199:

  Pick the component with which DataWeave is tightly integrated.

  A. All APIs
  B. Mule runtime
  C. Exchange
  D. Flow Designer
  B. Mule runtime

  ---

  Explanation/Reference:

  Correct answer is Mule runtime DataWeave is the MuleSoft expression language for accessing and transforming data that travels through a Mule app. DataWeave is tightly integrated with the Mule runtime engine, which runs the scripts and expressions in your Mule app. Mule Doc Reference : https://docs.mulesoft.com/mule-runtime/4.3/dataweave

• Question 200:

  Refer to the exhibits.

  

  The two Mule configuration files belong to the same Mule project. Each HTTP Listener is configured with the same host string and the port number, path, and operation values are shown in the display names. What is the minimum number of global elements that must be defined to support all these HTTP Listeners?

  A. 1
  B. 2
  C. 3
  D. 4
  C. 3

  ---

  Explanation/Reference:

  In this case three configurations will be required each for port 8000, 6000 and 7000. There would be three global elements defined for HTTP connections. Each HTTP connection will have host and port. One example shown below with host as localhost and port 6000
