How to execute parallel programs in MuleSoft?
scatter-gather or batch jobs can be used to do parallel processing in mulesoft.
How will you combine two arrays objects into one?

What are SDO and SMO?
SDO – Service data objects which represent variables and objects.
SMO- Service Model Object and it uses SDO for messages.
Define Mule UMO?
UMO is Universal Message Object; UMO components are also referred to as service components.
Explain the concept of Correlation Context?
When the mediation primitive requires passing the value from the request flow to response flow the correlation context plays the role.
Define the available resources used for modularizing configuration in mule?
Available resources are
A Mule instance is capable of loading multiple independent configuration files one after another.
As the term inheritance referred to represent the parent and child relationships between the instances this configuration also showcases the parent-child relationship between two configurations.
It strongly provides this dependency with the guarantee that no configuration file will be omitted at the time of application booting. It used the same name for the parent and child models.
What is the difference between service invoke and Callout?
Service invoke is an initial process of creating a service for either request or response flow.
Multiple instances of a service can be created and permitted into a flow, that allows a series of services to operate within the flow.
CallOut method is to receive messages and request the required service and operation in a flow. There is a CallOut node always presented into the median flow for connected target operation.

What is the use of Filter in a MuleSoft?
Filters help routers in making smart decisions on message delivery or request and response environment. It also provides insights to the router for deciding what to do with the messages in the transit stage.
How can you implement a loop in mediation?
By using Fan-in and Fan-out primitive.
