Demo Questions

Question 1
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?
  1. Hello- HTTP-] MS2-Three
  2. HTTP-JMS2-Three
  3. Helb-JMS1-HTTP-JMS2 -Three
  4. Hello-HTTP-Three
Correct answer: A
Question 2
Refer to the exhibits.
 
 
The web client sends a POST request to the ACME Order API with an XML payload. An error is returned.
What should be changed in the request so that a success response code is returned to the web client?
  1. Set a request header with the name Content-Type to a value of applicatron/octet-stream
  2. Set a request header with the name Content-Type to a value of application/xml
  3. Set a response header with the name Content-Type to a value of applkation/xml
  4. Set a response header with the name Content-Type to a value of application/octet-stream
Correct answer: B
Explanation:
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. As per RAML input is expected in application/xml.Hence correct answer is Set a request header with the name Content-Type to a

Each route in the Scatter-Gather sets the payload to the number shown in the label. What response is returned to a web client request to the HTTP Listener?
  1.  
  2.  
  3.  
  4.  
Correct answer: D
Explanation:
Correct answer is as below. 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.{'0': {'attributes': ...,'payload': '100'},'1': {'attributes': ...,'payload': '200'}}Bottom of Form

Question 4
A Utility.dwl file is located in a Mule project at src/main/resources/modules. The Utility.dwl hie defines a function named pascalize that reformats strings to pascal case.
What is the correct DataWeave to call the pascalize function in a Transform Message component?
  1.  
  2.  
  3.  
  4.  
Correct answer: B
Question 5
A RAML specification is defined to manage customers with a unique identifier for each customer record. What URI does MuleSoft recommend to uniquely access the customer identified with the unique ID 1234?
  1. /customers?custid=true&custid=1234
  2. /customers/1234
  3. /customers/custid=1234
  4. /customers?operation=get&custid=1234
Correct answer: B
Explanation:
URI parameter (Path Param) is basically used to identify a specific resource or resources . For eg : the URL to get employee details on the basis of employeeID will be GET /employees/{employeeID} where employees is resource and {employeeID} is URI parameter. Hence option 1is the correct answer

Question 6
Refer to the exhibits.
 
 
The orders.csv file is read, then processed to look up the orders in a database. The Mule application is debugged in Any point Studio and stops at the breakpoint.
What is the payload shown in the debugger at this breakpoint?
  1. 'none'
  2. The entire CSV file
  3. The database response
  4. 100
Correct answer: D
Question 7
A Mule application contains a global error handler configured to catch any errors.
Where must the global error handler be specified so that the global error handler catches all errors from flows without their own error handlers?
  1. A configuration properties file
  2. Nowhere, the global error handler is automatically used
  3. A global element
  4. The pom.xml file
Correct answer: C
Explanation:
Correct answer is A global elementGlobal error handlers are to be created in global element .Quick note to remember here is Global error handlers come in to picture only when there are no error handlers specified as flow level.Steps to create Global error handler1) Click Global Elements to open Global Configuration Elements. Global Elements is located below the Studio canvas2) In Global Configuration Elements, click Create to open the Choose Global Type dialog   3) From the dialog, select Global Configuration - Configuration, and then click OK to open the Configuration dialog.   4) From the select Configuration dialog, select allErrorHandler for the Default Error Handler field, and click OK.
Correct answer is A global element
Global error handlers are to be created in global element .
Quick note to remember here is Global error handlers come in to picture only when there are no error handlers specified as flow level.
Steps to create Global error handler
1) Click Global Elements to open Global Configuration Elements. Global Elements is located below the Studio canvas
2) In Global Configuration Elements, click Create to open the Choose Global Type dialog
 
 
3) From the dialog, select Global Configuration - Configuration, and then click OK to open the Configuration dialog.

Question 8
Refer to the exhibit.
 
What can be added to the flow to persist data across different flow executions?
  1. Key/value pairs in the ObjectStore
  2. Properties of the Mule runtime flow object
  3. properties of the Mule runtime app object
  4. session variables
Correct answer: A
Explanation:
An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. Internally, Mule uses object stores in various filters, routers, and other message processors that need to store states between messages.Object stores are available in all deployment targets. If you deploy your application to CloudHub, you can also use Object Store V2.Correct answer is Key/value pair in Object storeMuleSoft Documentation reference : https://docs.mulesoft.com/mule-runtime/4.3/mule-object-stores#use-cases
