An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy.
What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?

  1. Register the same API implementation in Runtime Manager to connect to API Manager
  2. Modify the API implementation to use auto-discovery to register with API Manager
  3. Upload the Mule application's JAR file to the API instance in API Manager
  4. Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager

Answer(s): B

Explanation:

Correct answer is Modify the API implementation to use auto-discovery to register with API Manager API Autodiscovery
Configuring autodiscovery allows a deployed Mule runtime engine (Mule) application to connect with API Manager to download and manage policies and to generate analytics data. Additionally, with autodiscovery, you can configure your Mule applications to act as their own API proxy.
When autodiscovery is correctly configured in your Mule application, you can say that your application's API is tracked by (green dot) or paired to API Manager. You can associate an API in a Mule setup with only one autodiscovery instance at a given time.

A flow needs to combine and return data from two different data sources. It contains a Database SELECT operation followed by an HTTP Request operation.
What is the method to capture both payloads so the payload from the second request does not overwrite that from the first?

  1. Put the Database SELECT operation inside a Cache scope
  2. Put the Database SELECT operation inside a Message Enricher scope
  3. Nothing, previous payloads are combined into the next payload
  4. Save the payload from the Database SELECT operation to a variable

Answer(s): D

Explanation:

Correct answer is Save the payload from the Database SELECT operation to a variable Response from HTTP request will override the payload and hence response of database SELECT can be lost. Best way to preserve is to assign payload of first operation to variable using TransformMessage.



A Mule project contains a MySQL Database dependency. The project is exported from Anypoint Studio so it can be deployed to CloudHub.

What export options create the smallest deployable archive that will successfully deploy to CloudHub?
What export option create their smallest deployable archive that will successfully deploy to CloudHub?





Answer(s): B



Why would a Mule application use the ${http.port} property placeholder for its HTTP Listener port when it is deployed to CloudHub?

  1. Allows CloudHub to automatically change the HTTP port to allow external clients to connect to the HTTP Listener
  2. Allows CloudHub to automatically register the application with API Manager
  3. Allows MuleSoft Support to troubleshoot the application by connecting directly to the HTTP Listener
  4. Allows clients to VPN directly to the application at the Mule application's configured HTTP port

Answer(s): A

Explanation:

This helps CloudHub to dynamically allocates a port at deployment time. MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/deploy-to-cloudhub#prerequisites
