  Explanation/Reference:

  Mule event is correct answer. Mule event has two parts which are as follows 1) Message (which contains payload and attributes like headers and query/uri parameters 2) Variables

  A. Application properties can be encrypted
  B. Application properties can be overridden with system properties

  D. Application properties provide easier way to manage configurable values
  C. Application properties can be defined in .yaml file only

  ---

  Explanation/Reference:

  Application properties can be defined in .yaml or in .properties file. MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/configuring- properties#supported_files

• Question 53:

  Refer to the exhibits.

  

  Set paylaod transformer is set the firstName and lastName of the customer as shown in below images.

  What is the correct Dataweave expression which can be added in message attribute of a Logger activity to access firstName (which in this case is Madhav) from the incoming event?

  A. firstName
  B. customer.firstName
  C. vars."customer.firstName"
  D. vars."customer"."firstName"
  D. vars."customer"."firstName"

  ---

  Explanation/Reference:

  Correct answer is vars."customer"."firstName"

  Please you can also access firstName using this syntax vars.customer.firstName.

• Question 54:

  Refer to the exhibits.

  

  The main flow contains a Flow Reference component configured to call the child flow What part(s) of a Mule event passed to the Flow Reference component are available in the child flow?

  A. The payload and all attributes
  B. The payload and all variables
  C. The entire Mule event
  D. The payload
  B. The payload and all variables

• Question 55:

  A Scatter-Gather processes three separate HTTP requests. Each request returns a Mule event with a JSON payload. What is the final output of the Scatter-Gather?

  A. An Array of the three Mule event Objects
  B. An Object containing all three Mule event Objects
  C. An Array of the three JSON payload Objects
  D. An Object containing all three JSON payload Objects
  B. An Object containing all three Mule event Objects

  ---

  Explanation/Reference:

  Correct answer is An Object containing all three Mule event Objects The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors.

  Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the

  same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is

  passed to the next event processor only after every route completes successfully.

  The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.

  Sample output is as below

• Question 56:

  Mule application contains ActiveMQ JMS dependency. Mule application was compiled and run successfully in Anypoint Studio. The mule application must now be exported from Anypoint Studio and shared with other developer. What export options should be selected to create the smallest JAR file that can be imported into other developer's Anypoint Studio and run successfully?

  A. Select only Attach Project Sources only
  B. Select both Attach Project Sources and Include project modules and dependencies option
  C. Select the Include project modules and dependencies option only
  D. De-select both Attach Project Sources and Include project modules and dependencies option
  A. Select only Attach Project Sources only

  ---

  Explanation/Reference:

  Correct answer is Select only Attach Project Sources only You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. Deselect the Include project modules and dependencies option. This option skips bundling the actual modules and external dependencies required to run the Mule application in a Mule runtime engine, creating a lightweight JAR file package that does not include any dependencies specified in the Mule application's pom.xml file. The generated JAR file is not a functional deployable archive and cannot be deployed to a Mule runtime engine, but instead offers a way to archive only the source files that make up the Mule application. This is the same as using the -lightWeightPackage flag when packaging using the Mule Maven Plugin and is useful if you want to distribute your project to other Studio installations because it only keeps a reference to all its dependencies. When you import a lightweight package into Studio, all your dependencies are automatically downloaded MuleSoft Doc Ref : https://docs.mulesoft.com/studio/7.8/import-export-packages

• Question 57:

  What payload is returned by a Database SELECT operation that does not match any rows in the database?

  A. false
  B. null
  C. Exception
  D. Empty Array
  D. Empty Array

  ---

  Explanation/Reference:

  Empty array is returned when no rows are matched.

  An HTTP:METHOD_NOT_ALLOWED error is thrown each time the webClient flow executes.

  What attribute value must be changed in the webClient flow's HTTP Request operation to prevent this error from being thrown?

  A. Change the protocol attribute's value to "HTTPS"
  B. Change the method attribute's value to “*”
  C. Change the path attribute's value to "/api/partners/fastShipping"
  D. Change the method attribute's value to "POST"
