• Question 163:

  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/Reference:

  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 164:

  Refer to the exhibit.

  

  What is the correct syntax to add a customer ID as a URI parameter in an HTTP Listener's path attribute?

  A. (customerlD)
  B. {customerlD}
  C. #[customerlD]
  D. ${ customerID}
  B. {customerlD}

• Question 165:

  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/Reference:

  *

  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. ------------------------------------------------------------------------------------------------------------------------- -------------------

  Correct Answer: In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy Reference: https://docs.mulesoft.com/api-manager/2.x/client-id-based-policies

• Question 166:

  Refer to the exhibits.

  

  All three of the conditions for the Choice router are true. What messages are written in the application log?

  A. Route1
  B. Route2
  C. Route1,Route2
  D. Route1,Route2,Default
  A. Route1

  ---

  Explanation/Reference:

  Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1. MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/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 167:

  From which application , Organization Administrators can approve/revoke/delete SLA tier access requests

  A. API Exchange
  B. API Portal
  C. API Gateway
  D. API Manager
  D. API Manager

  ---

  Explanation/Reference:

  Organization Administrators can approve/revoke/delete SLA tier access requests via API Manager only

• Question 168:

  A shopping API contains a method to look up store details by department.

  To get the information for a particular store, web clients will submit requests with a query parameter named department and uri parameter named storeId

  What is valid RAML snippet that supports requests from a web client to get a data for a specific storeId and department name?

  A. 1./department: 2. get: 3. uriParameter: 4. storeId:
  B. 1.get: 2.uriParameter: 3.{storeId}: 4.queryParameter: 5.department:
  C. 1.get: 2. queryParameter: 3. department: 4. uriParameter: 5. {storeId}:
  D. 1./{storeId}: 2. get: 3. queryParameter: 4. department:
  D. 1./{storeId}: 2. get: 3. queryParameter: 4. department:

• Question 169:

  A flow has a JMS Publish consume operation followed by a JMS Publish operation. Both of these operations have the default configurations. Which operation is asynchronous and which one is synchronous?

  A. Publish consume: Synchronous. Publish: Asynchronous.
  B. Publish consume: Asynchronous. Publish: Synchronous
  C. Publish consume: Asynchronous. Publish: Asynchronous
  D. Publish consume: Synchronous. Publish: Synchronous
  A. Publish consume: Synchronous. Publish: Asynchronous.

• Question 170:

  Refer to the exhibits. In the choice router, the When expression for the domestic shipping route is set to "#[payload= "FR"]".

  What is the output of logger after the execution of choice router is completed?

  

  A. "Domestic"
  B. "International"
  C. "US"
  D. A dataweave syntax error
  D. A dataweave syntax error

  ---

  Explanation/Reference:

  To compare, DataWeave syntax is #[payload == "FR"]. In this case only one = is used so it will give syntax error.
