Q120. 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?

Select both the options 1) Attach project sources 2) Include project module and dependencies

No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies

Select only below option 2) Include project module and dependencies

Select only below option 1) Attach project sources

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

Q130. Refer to the exhibits.

What DataWeave expression transforms the conductorIds array to the XML output?

1. 1. trains:
2. 2. conductorIds map ((engId, index) ->
3. 3. train: {
4. 4. engineerId: engId
5. 5. }
6. 6. )

1. 1. { trains:
2. 2.
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. }

1. 1. trains:
2. 2. {(
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. )}

1. 1. {( trains:
2. 2.
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {
5. 5. engineerId: engId
6. 6. }
7. 7. )
8. 8. )}

Points to remember:
* XML must have a root element.
* XML only allows one root element
* To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output
* When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}
-{ } are defining the object
( ) are transforming each element in the array as a key/value pair
* The transformation to XML would fail if the above mentioned considerations were not taken into account.
* Thus the transformation script declares a root element as trains and wraps the data in “{( )}”.
Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.
I call this a “Wrap The Map” scenario. Hope it would help you remember !

Q131. Which Mule component provides a real-time, graphical representation of the APIs and mule applications that are running and discoverable?

API Notebook

Runtime Manager

Anypoint Visualizer

API Manager

Correct answer is Anypoint Visualizer
MuleSoft Doc Ref : https://docs.mulesoft.com/visualizer/
Anypoint Visualizer provides a real-time, graphical representation of the APIs, and Mule applications that are running and discoverable. It also displays third-party systems that are invoked by a Mule API, proxy, or application within your application network. The data displayed in the graph is dynamically updated and does not require prior configuration. Additionally, the data displayed is secure, as only users with the proper permissions can view the application network graph.
