  1. One route in a Scatter-Gather throws an exception and the exception is not handled by the flow or resource being called. Without additional configuration how will Scatter-Gather handle this situation?
  1. The response from all successful routes will be aggregated and the failed route’s response throw an exception on a separate thread, the failed response can be caught and handled.
  2. Scatter-Gather retries failed route once; if the same exception is thrown, Scatter-Gather throws an exception.
  3. Scatter-Gather throws an exception, by default Scatter-Gather allows for no failed routes.
  4. The response from all successful routes will be aggregated and the failed route’s response is dropped.

ANSWER: c

  1. A mule application is configured with the following element in the global scope.

context:property-placeholder location=”classpath:my-mule-app-1.properties,file:///etc/mule/conf/my-mule-app-2.properties” />

  1. The application will deploy and my-mule-app-1. properties will take precedence.
  2. The application will deploy and my-mule-app-2. properties will take precedence.
  3. An exception will be thrown at startup due to the missing configuration of the local-override attribute.
  4. An exception will be thrown at startup due to the configuration of location attribute.

ANSWER: b

  1. When separating a mule application into multiple mule configuration (XML) files, which of the following is true?
  1. All flows must have unique name. regardless of whether the flows exist in different mule configuration (XML) files.
  2. Flows in one mule configuration (XML) file doesn’t have visibility into flows of another mule configuration (XML) file.
  3. Global elements defined in one mule configuration (XML) file cannot be referenced from another mule configuration (XML) file.
  4. Subflows, because they do not have a message source, cannot be referenced from another mule configuration (XML) file.

ANSWER: a

  1. Mule applications deployed to various environments (QA, Staging, Production) do not contain the same connection attribute values. How can you best ensure the connection attributes values changes based in environment context?
  1. If deploying to mule ESB, go to MMC and change the values of the deployed application’s properties through a property administrator. If deploying to cloudhub , go to web based management console and change the values of deployed application properties from the property administrator.
  2. Create multiple property placeholders. For example, context:property-placeholder location=’development.properties’ and context:property-placeholder location=’production.properties’. On Deployment, pass an argument to mule runtime to ensure correct property placeholder is respected.
  3. Create multiple XML files, each containing properties for the respective environment. On Deployment, pass an argument to the Mule runtime to ensure the correct XML file is used in the application.
  4. Create a dynamic property placeholder by using a property in the location attribute. For example, context:property-placeholder location=’myApp-${env}.properties’. On deployment, pass an argument to mule runtime to ensure correct property file is loaded.

ANSWER: d

  1. What does the APIKit router notdo?
  1. Validate incoming request schemas based on the RAML definition.
  2. Set the baseUri of the application based on the RAML definition.
  3. Route requests to specific flows where flow mapping is defined, regardless of naming syntax.
  4. Implicitly route requests to flows with naming syntax {method}:{resource}:{routerConfigName}

ANSWER: c

  1. Sub-flows pick up the execution context (exception handler, transaction, properties) from where?
  1. The Calling flow
  2. The global configuration
  3. The application’s context
  4. The sub flow’s global scoped variables.

ANSWER: a

  1. What does the payload of a Mule message always contain?
  1. A Java object determined by the messages source and processors
  2. A Java object implementing the collection interface (such as an ArrayList)
  3. A XML representation of the data
  4. A JSON representation of data

ANSWER: a

  1. A flow needs to be exposed at for users to retrieve data. Assuming the flow logic already exists, what are the minimum elements needed to achieve this ?

  2. An http:listener-config and a RAML file
  3. An http:listener endpoint and an http:listener-config
  4. An http:listener-config
