Mulesoft Interview Questions With Answers - Part 2

Bonjour!

Let's take a look at some more Mulesoft basic interview-related questions!

Which component is used for schema validation and routing incoming Mule messages against RAML?

APIkit Router. 

Mule provides APIkit Router for Schema validation and routing the incoming Mule messages, serializing responses, validating payloads, Query parameters, URI parameters against RAML. 

Can you create a custom connector? 

Yes. 

When an API specification is published to Anypoint Exchange, it automatically generates a connector for it.

What is the purpose of a domain project? 

The main purpose of a domain project is to have all the globally shared configurations for the projects. All the shared resources can be configured in a domain project. Mule applications can be associated only with one domain project. However, a domain project can be associated with multiple mule applications.

How do you override application properties? 

You can configure your Mule application to automatically load properties from properties files based on different environments (Production, development, testing, QA) using property placeholders. 

1.  Create a properties file for each development environment in your Mule application.
2. Configure a property placeholder in your application to look for the environment at the time of launch.
3. Set environment variable one each for the different environment.

The property placeholder will then take up an environment variable value and based on that use the properties file.

Where are the HTTP, database configurations defined? 

Global.xml

What is the use of Message Enricher? 

In Mule 3, Message enricher is a component used to enrich the current message with additional information from a separate resource without disturbing the current payload.

Enricher is used in scenarios where the target system needs more information than the source system can provide. It calls an external system or doing some transformation to the current payload and saving it in a target variable.

Do we have Message Enricher in Mule 4? 

In Mule 4, We don't have message enricher anymore. 

Now, every component is embedded with a target variable which solves the purpose. 

 

How can we store sensitive data such as Client ID and Client Secret? 

Properties in Mule 4 can be encrypted to store sensitive data such as Client ID and Client Secret. We can encrypt a .yaml or .properties file using the secure properties module. 

Which connector is used for handling SOAP requests?

Web service Consumer.
