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

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.

Mule application contains ActiveMQ JMS dependency. Mule application was compiled and run successfully in Anypoint Studio. The mule application must now be exported from Anypoint Studio and shared with other developer. What export options should be selected to create the smallest JAR file that can be imported into other developer's Anypoint Studio and run successfully?

A. Select only Attach Project Sources only

B. Select both Attach Project Sources and Include project modules and dependencies option

C. Select the Include project modules and dependencies option only

D. De-select both Attach Project Sources and Include project modules and dependencies option

A. Select only Attach Project Sources only

Explanation:
Correct answer is Select only Attach Project Sources only.
You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace.
Deselect the Include project modules and dependencies option.
This option skips bundling the actual modules and external dependencies required to run the Mule application in a Mule runtime engine, creating a lightweight JAR file package that does not include any dependencies specified in the Mule application’s pom.xml file.
The generated JAR file is not a functional deployable archive and cannot be deployed to a Mule runtime engine, but instead offers a way to archive only the source files that make up the Mule application. This is the same as using the -lightWeightPackage flag when packaging using the Mule Maven Plugin and is useful if you want to distribute your project to other Studio installations because it only keeps a reference to all its dependencies.
When you import a lightweight package into Studio, all your dependencies are automatically downloaded.
