Mulesoft Interview Question AND Answers

The following mentioned are Mulesoft Interview Question and Answers:

  1. What is MuleSoft?

MuleSoft is a cloud-based solution provider that connects with data, applications, and APIs on-premises. It operates on the “Any Point Connectivity Model,” which joins current SaaS-based applications or a set of APIs via a single API interface. This integration support built on service-oriented architecture is versatile in accessing all essential apps. MuleSoft manages the programmable web portal, which is used to create online, mobile, and other user applications.

  1. What is ESB?

An enterprise service bus is characterized as a middleware software architecture that aids in providing core services for more complicated systems. An ESB, for example, includes the characteristics required for creating a service-oriented architecture. In general, an ESB is a system that controls access to numerous applications and services to deliver a single, simple, and consistent interface to earned-users via Web- or forms-based client-side front ends.

  1. Why Mulesoft is most well-liked over different ESB implementations?

Mule is lightweight but incredibly adaptable, allowing you to start small and gradually connect many applications. Whether they occur within the same virtual machine or over the internet, and irrespective of the underlying transport protocol employed, several industrial ESB implementations offer limited functionality or are built on top of an existing application server or electronic messaging server, tying you to that specific trafficker. Mule is vendor-independent. Therefore completely different trafficker implementations can connect to it. When you utilize Mule, you are never restricted to a particular trafficker.

  1. What are the different tools and services Mulesoft provides?

MuleSoft is used to efficiently and methodically integrate data. It also offers a wide range of products and services. The following is a list of the primary tools and services provided by MuleSoft:

  1. What is the difference between Callout and Service Invoke in Mulesoft?

In Mulesoft, the following are the distinctions between Callout and Service Invoke:

  • Callout: The callout is used to receive messages and call the specified services and actions. A callout node for each associated target operation in the median flow. In the event of a successful call, the response flow’s callout response node receives a response message. If the call fails, the callout is configured to retry service invocations based on the type of failure received.
  • Service Invoke: The Service Invoke is used to request a service. The service may be a request/response or a one-way transaction. It could be either a request or a reaction to a mediation flow. After allowing numerous instances of a service to call primitives in a flow, a sequence of service invocations is executed.
  1. What is Mule Expression Language?

Mule Expression Language, or MEL, is a lightweight mule-specific language that can be used to acquire and analyze information in the payload.

  1. What is API?
  • API is an abbreviation for Application Programming Interface. It is a software interface that allows two apps to communicate without user participation.
  • APIs enable a product or service to communicate with other products and services without knowing how they are built.

A few types of ESPs used in the market are:

  • Mule ESB
  • JBoss fuse ESB
  • Talend
  1. What is Endpoint in Mule?
  • An endpoint in MuleSoft denotes a specific protocol usage. It is used to poll, read from, or write to a destination.
  • As a result, it determines which underlying entities are used with a dependent connector.
  1. Name different types of web services

Other types of web services:

  • RESTful web services and
  • SOAP web services.
  1. What are the configuration patterns provided by MuleSoft?

  • Expression
  • Routing
  • Duplicate_Message
  • Source_Response
  • Timeout
  • Security
  • Connectivity
  • Validation
  1. Name the languages supported by MuleSoft?

The supported languages of MuleSoft are:

  • Ruby.
  • Python.
  • Groovy.
  • Javascript
  1. What are the advantages of using ESB?

The advantages are:

  • It offers high-level control from a Web-based portal. It offers multiple connectivity options by utilizing SaaS-based apps.
  • API and Analytical administration are provided by ESB.
  • The ESB is outfitted with many facilities that can correct faults and automate testing.
  • EDI (Electronic Data Interchange)/B2B integration (business to business).
  • Allows for batch integration by utilizing real-time integration mechanisms.
  1. Name the flow processing strategies in MuleSoft.

The strategy types in flow processing are:

  • Non-blocking flow processing
  • A queued asynchronous flow processing
  • Asynchronous flow processing
  • Custom flow processing
  • Tread per processing
  • Synchronous flow processing
  • Queued flow processing
  1. What are message sources in Mule ESB?

Message sources are Anypoint connectors that connect to a specific external source via conventional protocols like HTTP, FTP, SMTP, or a third-party API like Salesforce.com, Twitter, or MongoDB.

  1. How can you change the runtime changes using mediation primitive?

In ESB, we have a future called Promotable properties. During development, we can configure this future. Then we can alter it at runtime without restarting the server, and it may be published.

  1. What Are Differences Between Mule And Other Commercial Tabs?

Mule supports a wide range of deployment options instead of a prescriptive deployment strategy. Mule can embrace the architectural style and SOA practices in the location where it is installed instead of the prescribed SOA methodology. Mainly concerned with higher-level issues, Mule is deeply involved with all integration aspects.

Strict full-stack web service orientation, but Mule’s capabilities as an integration framework allow it to support a wide range of additional protocols. MuleSource has recently made significant progress in the area of comprehensive documentation.

  1. Mention the various types of variables in Mule.
  • Flow Variable: This variable is used to set or remove variables linked with a specific message in the current flow.
  • Record Variable: Batch processing flows make use of the Record Variable.
  • Session Variable: This variable is used to set or remove variables linked with a particular message throughout the lifecycle.
  1. How to create and consume SOAP service in Mule?
  • Creating SOAP Service – We can create a SOAP service the same as we make Mule Project With RAML. The only change is instead of RAML, we need to import Concert WSDL.
  • Consuming SOAP Service – We can use Web Service Consumer or CXF component in our mule flow to access/consume SOAP service.
  1. How to select an ESB?
  • Usability: How complex is the installation procedure? The ESB’s learning curve should not be there.
  • Maintainability: How will the product be monitored? If a graphical user interface (GUI) terminal is accessible for monitoring the services.
  • Community: Is there an active ESB community? Various discussion boards, tutorials, and so on. Enterprise Support- How dependable is the product support? What services are offered?
  • Flexibility: Can the ESB be customized to fit the needs of the business?
  • Reliability: The ESB’s dependability. Its current users, as well as any case studies that are accessible.
  • Price: The price of the ESB. Its licensing policies Support charges, for example.
  1. What is the difference between ESB and JMS?
  • ESB provides middleware and interfaces that enable organizations to link their applications without writing code.
  • JMS enables messaging and simplifies the interaction between modules/applications.
  1. Why do we need ESB?

ESB, a middleware technology, is a Bus-like architecture used for the integration of the heterogeneous systems. In ESB, each application is independent and yet able to communicate with other systems. It is thus, preventing the scalability issues and ensuring that the communication is happening only through it.

  1. Is Mulesoft a middleware?

Enterprise Mule Service Bus is defined as a middleware solution that connects to the enterprise fast, efficiently, and securely. In contrast to traditional middleware software, Mule as an ESB is defined as a Java-based middleware solution that is simple to use and scale. A web service is described as a set of open protocols and standards used to exchange data between applications or systems.
