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

• Question 61:

  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

  ---

  Explanation

• Question 62:

  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

  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 63:

  An API specification is designed using RAML. What is the next step to create a REST Connector from this API specification?

  A. Download the API specification and build the interface using APIkit
  B. Publish the API specification to Any point Exchange
  C. Implement the API specification using flow designer in Design Center
  D. Add the specification to a Mule project's src/main/resources/api folder
  B. Publish the API specification to Any point Exchange

  ---

  Explanation

  API Exchange creates REST conenctor automtaically once API is published. Hence correct answer is Publish the API specification to Any point Exchange

• Question 64:

  Which one of them is NOT a flow in Mule?

  A. sync flow
  B. subflow
  C. async sub flow
  D. async flow
  C. async sub flow

  ---

  Explanation

  Correct answer is async sub flow. Rest are valid flows in Mule. Sub flow is always synchronous.

• Question 65:

  A mule project contains MySQL database dependency . The project is exported from Anypoint Studio so that it can be deployed to Cloudhub. What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?

  A. Select both the options 1) Attach project sources 2) Include project module and dependencies
  B. No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies
  C. Select only below option 2) Include project module and dependencies
  D. Select only below option 1) Attach project sources
  C. Select only below option 2) Include project module and dependencies

  ---

  Explanation

  You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option. We need to select Include project module and dependencies As actual modules and external dependencies required to run the Mule application in a Mule runtime engine Hence correct answer is Select only below option 2) Include project module and dependencies MuleSoft Doc Ref : https://docs.mulesoft.com/studio/7.5/import-export-packages#exporting- a-studio-project-to-a-deployable-mule-application

• Question 66:

  An API instance of type API endpoint with API proxy is created in API manager using an API specification from Anypoint Exchange. The API instance is also configured with an API proxy that is deployed and running in CloudHub.

  An SLA- based policy is enabled in API manager for this API instance.

  Where can an external API consumer obtain a valid client ID and client secret to successfully send requests to the API proxy?

  A. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy
  B. In Anypoint Studio, from components generated by APIkit for the API specification
  C. In Anypoint Studio, from components generated by Rest Connect for API specification
  D. In Runtime Manager, from the properties tab of the deployed approved API proxy
  A. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy

  ---

  Explanation

  *

  When a client application is registered in Anypoint Platform, a pair of credentials consisting of a client ID and client secret is generated.

  *

  When the client application requests access to an API, a contract is created between the application and that API.

  *

  An API that is protected with a Client ID Enforcement policy is accessible only to applications that have an approved contract. ------------------------------------------------------------------------------------------------------------------------- -------------------- In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy

• Question 67:

  A Mule application's HTTP Listener is configured with the HTTP protocol. The HTTP listeners port attribute is configured with a property placeholder named http.port. The mule application sets the http.port property placeholder's value to 9090

  The Mule application is deployed to CloudHub without setting any properties in the Runtime manager Properties tab and a log message reports the status of the HTTP listener after the Mule application deployment completes.

  After the mule applications is deployed, what information is reported in the worker logs related to the port on which the Mule application's HTTP Listener listens?

  A. The HTTP Listener is listening on port 80
  B. The HTTP Listener is listening on port 9090
  C. The HTTP Listener is listening on port 8081
  D. The HTTP Listener failed to bind to the port and is not listening for connections
  C. The HTTP Listener is listening on port 8081

  ---

  Explanation

  Cloudhub expose services on port 8081 and override value in http.port with this one . Sample log in Runtime Manager is below

  21:15:53.148 08/08/2021 Worker-0 ArtifactDeployer.start.01 INFO Listening for connections on 'http://0.0.0.0:8081'

• Question 68:

  Where would you create SLA Tiers for an API?

  A. Exchange
  B. API Manager
  C. Anypoint Studio
  D. In RAML specifications
  B. API Manager

  ---

  Explanation

  MuleSoft Doc Ref : https://docs.mulesoft.com/api-manager/2.x/policy-mule3-tutorial- manage-an-api#to-add-the-tier

  Steps to create SLA Tier are as follows:

  1) In API Manager, in API Administration, click a version.

  2) Check that the API supports resource-level policies: On the API version details page, in Status, click Configure Endpoint, and check that Type is RAML.

  3) Choose the SLA Tiers, and click Add SLA Tier. Set up limit on SLA tier

• Question 69:

  What is the output of Dataweave Map operator?

  A. Map
  B. Object
  C. String
  D. Array
  D. Array

  ---

  Explanation

  Returns an array that is the result of applying a transformation function (lambda) to each of the elements.

  MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/dataweave-cookbook-map The map operator is a function in Dataweave which iterates over the items in an array and outputs them into a new array. It basically accepts input as

  a list of items in an array and manipulates the items in the array in order to form a new array as an output.
