• Question 202:

  A Batch Job scope has five batch steps. An event processor throws an error in the second batch step because the input data is incomplete. What is the default behavior of the batch job after the error is thrown?

  A. All processing of the batch job stops.
  B. Event processing continues to the next batch step.
  C. Error is ignored
  D. Batch is retried
  A. All processing of the batch job stops.

  ---

  Explanation

  In case of an error , batch job completes in flight steps and stops further processing. MuleSoft Doc Ref : Handling Errors During Batch Job | MuleSoft Documentation The default is all processing will stop but we can change it by Max Failed

  Record field. General -> Max Failed Records: Mule has three options for handling a record-level error:

  Finish processing, Continue processing and Continue processing until the batch job accumulates a maximum number of failed records. This behavior can be controlled by Max Failed Records.

  The default value is Zero which corresponds to Finish processing.

  The value -1, corresponds to Continue processing.

  The value +ve integer, corresponds to Continue processing until the batch job accumulates a maximum number of failed records

• Question 203:

  Refer to the exhibit.

  

  What Database expression transforms the input to the output?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  ---

  Explanation

  This kind of questions are best solved with filtering technique. Key thing to note here is XML attributes are always access by @ notation. So in this example orderId can be accessed as @OrderId which makes option 3 and option 4 false. Now difference in optin and option 2 is in mapping of lineItemPrice. Correct syntax to format a String in Numbse is value.price as Number. Hence option 2 is correct

• Question 204:

  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?

  A. Hello- HTTP-] MS2-Three
  B. HTTP-JMS2-Three
  C. Helb-JMS1-HTTP-JMS2 -Three
  D. Hello-HTTP-Three
  A. Hello- HTTP-] MS2-Three

• Question 205:

  What of the below is not a feature of API Notebooks?

  A. API documentation
  B. Creates a client for an API
  C. Creates a mock service for an API
  D. Perform authenticated live calls on a real server
  C. Creates a mock service for an API

  ---

  Explanation

  API Notebook is an open source, shareable web application for API documentation, interactive API tutorial and example generatation, and a client for your API endpoints. Using API Notebook, you can make requests and quickly transform the responses into readable format. However it cannot be used to mock service for an API. MuleSoft Doc Ref : https://docs.mulesoft.com/api-manager/1.x/api-notebook-concept

• Question 206:

  How are multiple conditions used in a Choice router to route events?

  A. To route the same event to the matched route of EVERY true condition
  B. To find the FIRST true condition, then distribute the event to the ONE matched route.
  C. None of these
  D. To find the FIRST true condition, then route the same event to the matched route and ALL FOLLOWING routes
  B. To find the FIRST true condition, then distribute the event to the ONE matched route.

  ---

  Explanation

  Choice router finds the FIRST true condition, then distribute the event to the ONE matched route.

  MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.1/choice-router-concept The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each

  expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages. Only one of the routes in the Choice router executes, meaning

  that the first expression that evaluates to true triggers that route's execution and the others are not checked. If none of the expressions are true, then the default route executes.

  

• Question 207:

  What is the correct syntax to define and call a function in Database?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  Explanation

  Keyword to ad function in Dataweave transformation is fun. Hence option 2 and 4 are invalid. Also parameters needs to be passed exactly in same order as defined in function definition. Hence correct answer is'fun addKV( object: Object, key:

  String, value: Any) =

  object ++ {(key):(value)}

  addKV ( {"hello': "world"}, "hola", "mundo" )

  MuleSoft Documentation Reference : https://docs.mulesoft.com/mule- runtime/4.3/dataweave-functions

  DataWeave Function Definition Syntax

  To define a function in DataWeave use the following syntax:

  fun myFunction(param1, param2, ...) =

  The fun keyword starts the definition of a function.

  myFunction is the name you define for the function.

  Function names must be valid identifiers.

  (param1, param2, ... , paramn) represents the parameters that your function accepts. You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses. The = sign marks the beginning of the

  code block to execute when the function is called. represents the actual code that you define for your function.

• Question 208:

  Refer to the exhibits.

  

  

  A web client submits a request to http://localhQst:8081 /flights. What is the result at the end of the flow?

  A. "string"
  B. "Java"
  C. "object"
  D. "XML"
  A. "string"

  Explanation

• Question 209:

  Refer to the exhibit.

  

  What is the correct syntax to add an employee ID as a URI parameter in an HTTP Listener path?

  A. (employeelD)
  B. ${emp!oyeelD}
  C. {employeelD}
  D. # [employeelD]
  C. {employeelD}

  ---

  Explanation

  The path of an HTTP listener can be static, which requires exact matches, or feature placeholders. Placeholders can be wildcards (*), which match against anything they are compared to, or parameters ({param}), which not only match against

  anything but also capture those values on a URI parameters map.

  Take the following example paths for three listeners using a configuration that establishes api/v1 as the base path:

  account/mulesoft/main-contact: only match the exact path request http://awesome- company.com/api/v1/account/mulesoft/main-contact account/{accountId}/main-contact: matches all path requests structured similarly, such as http://

  awesome-company.com/api/v1/account/salesforce/main-contact, and save salesforce as the value of accountId. account/{accountId}/*: matches all path requests different from main-contact, such as http://awesome-company.com/api/v1/

  account/mulesoft/users, and save mulesoft as the value of accountId.
