Salesforce SALESFORCE-MULESOFT-DEVELOPER-I Online Questions & Answers

• Question 101:

  What should this endpoint return considering the API is build using standard practices? http://dev.acme.com/api/patients?year=2021

  A. Patient with id 2021
  B. Patients from year 2021
  C. No patients
  D. All patients
  B. Patients from year 2021

  ---

  Explanation

  The thing to note here is that year is not a query parameter and not the uri parameter. Hence it will filter all the patients and return the ones for whom year is 2021

• Question 102:

  Refer to the exhibits.

• Question 103:

  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

  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 104:

  Refer to the exhibits.

  

  

  The Validation component in the Try scope throws an error.

  What response message is returned to a client request to the main flow's HTTP Listener?

  The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?

  A. Success - main flow
  B. Error - main flow
  C. Error - Try scope
  D. Validation Error
  A. Success - main flow

  ---

  Explanation

  Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow. Hence correct answer is Success - main flow 1) HTTP listener received request 2) The Flow Reference calls the child flow 3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops #[error.description] = "payload is not a valid INTEGER value" #[error.errorType] = VALIDATION:INVALID_NUMBER 4) The On Error Continue handles the errorThe payload is set to "Error Sub Flow" 5) "Error Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success Finished Main Flow" 6) "Success Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200 As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.

• Question 105:

  Refer to the exhibit.

  

  

  The main flow is configured with their error handlers. A web client submit a request to the HTTP Listener and the HTTP Request throws an HTTP:NOT_FOUND error.

  What response message is returned?''

  What response message is returned?

  A. APP: API RESOURCE NOT FOUND
  B. HTTP: NOT FOUND
  C. other error
  D. success - main flow
  A. APP: API RESOURCE NOT FOUND

  ---

  Explanation

  Correct answer is APP: API RESOURCE NOT FOUND

  1) A web client submits the request to the HTTP Listener.

  2) The HTTP Request throws an "HTTP:NOT_FOUND" error, execution halts.

  3) The On Error Propagate error Handler handles the error. In this case ,HTTP:NOT_FOUND error is mapped to custom error

  APP:API_RESOURCE_NOT_FOUND. This error processor sets payload to APP:API_RESOURCE_NOT_FOUND.

  4) "APP:API_RESOURCE_NOT_FOUND. " is the error message returned to the requestor in the body of the HTTP request with HTTP Status Code: 500 Reference Diagram:

  

• Question 106:

  Refer to the exhibit. APIkit is used to generate flow components for the RAML specification.

  How many apikit:router XML elements are generated to handle requests to every endpoint defined in the RAML specification?

  

  A. 3
  B. 5
  C. 2
  D. 1
  D. 1

  Explanation

• Question 107:

  B. Email the owners of the API
  C. Create a new client application
  D. No additional steps needed
  A. Request access to the API in Anypoint Exchange
