• Question 112:

  An app team is developing a mobile banking app. It took them two months to create their own APIs to access transaction information from a central database. The app team later found out that another team had already built an API that accesses the transaction information they need.

  A. Center of Excellence
  B. Center for Enablement
  C. MuleSoft Support Center
  D. Central API Review Board
  B. Center for Enablement

  Explanation

  Center for Enablement is correct answer .It is a cross-functional team typically staffed with members from central IT, line-of-business departments, and digital innovation teams charged with productizing, publishing, and harvesting reusable assets and best practices. In this case , app team would have checked first with Center for Enablement before developing their own API's. Hence could have avoided re-work

• Question 113:

  Refer to the payload.

  

  The Set payload transformer sets the payload to an object. The logger component's message attribute is configured with the string "Result #["INFO"++ payload]"

  What is the output of logger when this flow executes?

  A. Result INFOpayload
  B. Result INFO{"student":{"name":"Anay","age":6}}
  C. 1. 1. "You called the function '++' with these arguments: 2.2. 1: String ("INFO") 3.3: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age: 6 as Numbe...)
  D. Error : You evaluated inline expression # without ++
  C. 1. 1. "You called the function '++' with these arguments: 2.2. 1: String ("INFO") 3.3: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age: 6 as Numbe...)

  ---

  Explanation

  Correct answer is as below as concatenation operation works only with string and not with the objects. In this case payload is object. "You called the function '++' with these arguments:

  1: String ("INFO")

  2: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age

• Question 115:

  Refer to the exhibits.

  

  The Batch job processes an array of strings.

  What information is logged by the logger component after the batch job scope completes processing of the input payload?

  A. Total Records Processed: 3 Successful Records: 3 Failed Records: 0 payload: ["A","B","C"]
  B. ["A","B","C"]
  C. Total Records Processed: 3 Successful Records: 3 Failed Records: 0 payload: ["a", "b", "c"]
  D. Total Records Processed: 3 Successful Records: 3 Failed Records: 0

  ---

  Explanation

  On complete phase only has access to batch job result statistics and payload is not available. Total Records Processed: 3 Successful Records: 3 Failed Records: 0 On Complete During this phase, you can optionally configure the runtime to create a report or summary of the records it processed for the particular batch job instance. This phase exists to give system administrators and developers some insight into which records failed to address any issues that might exist with the input data. Sample output is as below

  Explanation

  lookup(String, Any, Number)

  This function enables you to execute a flow within a Mule app and retrieve the resulting payload.

  It works in Mule apps that are running on Mule Runtime version 4.1.4 and later. Similar to the Flow Reference component (recommended), the lookup function enables you to execute another flow within your app and to retrieve the resulting

  payload. It takes the flow's name and an input payload as parameters. For example, lookup("anotherFlow", payload) executes a flow named anotherFlow.

• Question 120:

  B. Nowhere, the global error handler is automatically used
  C. A global element
  D. The pom.xml file
  C. A global element

  ---

  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.
