• Question 26:

  A Mule project contains a DataWeave module like WebStore.dwl that defines a function named loginUser. The module file is located in the project's src/main/resources/libs/etl folder.

  What is correct DataWeave code to import all of the WebStore.dwl file's functions and then call the loginUser function for the login "[email protected]"?

  A. 1. 1. import libs.etl 2. 2. --3. 3. WebStore.loginUser("[email protected]")
  B. 1. 1. import * from libs::etl 2. 2. --3. 3. WebStore::loginUser("[email protected]")
  C. 1. 1. import libs.etl.WebStore 2. 2. --3. 3. loginUser("[email protected]")
  D. 1. 1. import * from libs::etl::WebStore 2. 2. --3. 3. loginUser("[email protected]")
  D. 1. 1. import * from libs::etl::WebStore 2. 2. --3. 3. loginUser("[email protected]")

  Explanation/Reference:

  *

  To use custom modules, you need to import the module or functions you want to use by adding the import directive to the head of your DataWeave script, for example:

  1) Does not identify any functions to import from the String module:

  import dw::core::Strings

  2) To identify a specific function to import from the String module:

  import camelize, capitalize from dw::core::Strings

  3) To import all functions from the String module:

  import * from dw::core::Strings

  The way you import a module impacts the way you need to call its functions from a DataWeave script. If the directive does not list specific functions to import or use * from to import all functions from a function module, you need to specify the

  module when you call the function from your script.

  *

  In given scenario, it's mentioned to import all of the WebStore.dwl So correct answer is:

• Question 27:

• Question 28:

  Refer to the exhibit.

  

  What can be added to the flow to persist data across different flow executions?

  A. Key/value pairs in the ObjectStore
  B. Properties of the Mule runtime flow object
  C. properties of the Mule runtime app object
  D. session variables
  A. Key/value pairs in the ObjectStore

  ---

  Explanation/Reference:

  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 store MuleSoft Documentation reference : https://docs.mulesoft.com/mule-runtime/4.3/mule-object-stores#use-cases

• Question 29:

  A REST connect module is generated for a RAML specification. and then the rest connect module is imported in mule application in Anypoint Studio. For each method of the RAML specification , what does the REST connect module provide?

  A. A scope
  B. A flow
  C. An operation
  D. An event source
  C. An operation

  ---

  Explanation/Reference:

  Correct answer is an operation. For each method of the RAML specification , REST connect module provide an operation. Please refer to the below screenshot.

  

• Question 30:

  Refer to the exhibit. The Default scope in the Choice router recursively calls the color flow.
