Mulesoft Interview Questions
1) What is Mulesoft?
Answer ) MuleSoft provides the most widely used integration platform (Mule ESB & CloudHub) for connecting SaaS & enterprise applications in the cloud and on-premise. know more at Mulesoft online training
2) What is Mule ESB?
Answer ) Mule ESB is the runtime engine of Anypoint Platform, is a lightweight Java-based enterprise service bus (ESB) and integration platform that allows developers to connect applications together quickly and easily, enabling them to exchange data.
3) What is MuleSoft Anypoint platform used for?
MuleSoft’s Anypoint Platform of integration products is designed to tie together software as a service (SaaS) and on-premises software
4) Is MuleSoft open source?
Answer ) mulesoft is open source technology and it provides open source SOA middleware and related products.
5) What is Mulesoft used for?
Answer ) Mulesoft is an integration platform that allows developers to connect applications together quickly and easily, enabling them to exchange data.
6) Is Mulesoft a middleware?
Answer ) Mule Enterprise Service Bus is a middleware technology that quickly, easily, and securely connects the enterprise. Unlike typical middleware software, Mule as an ESB is a Java-based middleware solution that is easy to use and easy to scale.
7) Why do we need ESB?
Answer ) ESB, a middleware technology, is a Bus-like architecture used to integrate heterogeneous systems. In ESB, each application is independent and yet able to communicate with other systems. It, thus, prevents scalability issues and ensures that communication happens only through it. know more at Mulesoft training
8) What are Web Services?
Answer ) Web service is a functionality or a small piece of program in any programming language that can be accessed over HTTP. Message format can be XML or JSON or any other program as long as the other programs can understand and communicate.
A Web service can be of synchronous or asynchronous type. Any web service has a server-client relationship and it can have multiple clients.
9) What is the use of Web service?
Answer ) Web services are XML-based information exchange systems that use the Internet for direct application-to-application interaction. These systems can include programs, objects, messages, or documents. A web service is a collection of open protocols and standards used for exchanging data between applications or systems.
10) What are the different types of Web services?
Answer ) There are mainly two types of web services.
- SOAP web services.
- RESTful web services.
11) What is a REST web service?
Answer ) Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability, that enable services to work best on the Web. know more at mulesoft online course
12) What are the advantages of RESTful web services?
Answer ) Advantages of RESTful Web Services
Fast: RESTful Web Services are fast because there is no strict specification like SOAP. It consumes less bandwidth and resource.
Language and Platform independent: RESTful web services can be written in any programming language and executed in any platform.
Can use SOAP: RESTful web services can use SOAP web services as the implementation.
Permits different data format: RESTful web service permits different data format such as Plain Text, HTML, XML and JSON.
13) What is SOAP Web Service?
Answer ) SOAP stands for Simple Object Access Protocol. It is a XML-based protocol for accessing web services. SOAP is a W3C recommendation for communication between two applications.
SOAP is XML based protocol. It is platform independent and language independent. By using SOAP, you will be able to interact with other programming language applications.
14) What are the advantages of Soap Web Services?
Answer ) WS Security: SOAP defines its own security known as WS Security.
Language and Platform independent: SOAP web services can be written in any programming language and executed in any platform.
15) What is the difference between SOAP and REST?
Answer ) SOAP -> REST
1. SOAP is a protocol. -> REST is an architectural style.
2. SOAP stands for Simple Object Access Protocol. -> REST stands for REpresentational State Transfer.
3. SOAP can’t use REST because it is a protocol. -> REST can use SOAP web services because it is a concept and can use any protocol like HTTP, SOAP.
4. SOAP uses services interfaces to expose the business logic. -> REST uses URI to expose business logic.
5. SOAP defines standards to be strictly followed. -> REST does not define too much standards like SOAP.
6. SOAP defines standards to be strictly followed. -> REST does not define too much standards like SOAP.
7. SOAP requires more bandwidth and resource than REST. -> REST requires less bandwidth and resource than SOAP.
8. SOAP defines its own security. -> RESTful web services inherit security measures from the underlying transport.
9. SOAP permits XML data format only. -> REST permits different data format such as Plain text, HTML, XML, JSON etc.
10. SOAP is less preferred than REST. -> REST more preferred than SOAP.16) What is a Web service API?
Answer ) An API (Application Programming Interface) is the means by which third parties can write code that interfaces with other code. A Web Service is a type of API, one that almost always operates over HTTP (though some, like SOAP, can use alternate transports, like SMTP). know more at Mulesoft online training from India
17) What is RAML?
Answer ) RAML stands for RESTful API Modeling Language is a YAML-based language for describing RESTful APIs. It provides all the information necessary to describe RESTful or practically RESTful APIs.
RAML is similar to WSDL, it contains endpoint URL, request/response schema, HTTP methods and query and URI parameter.18) Why we use RAML?
Answer) RAML helps client know, what the service is and how all the operations can be invoked. RAML helps the developer in creating the initial structure of this API. RAML can also be used for documentation purpose.
19) What are the different types of variables in Mule ESB?
Answer ) The different types of variables in Mule ESB are:
- Flow Variable
- Session Variable
- Record Variable
20) What are the various types of Exception Handling in Mule ESB?
Answer ) The types of exception handling in Mule ESB are:
- Default Exception Handling
- Global Exception Handling
- Catch Exception Handling
- Choice Exception Handling
21) What are the Flow Processing Strategies?
Answer ) Synchronous Flow Processing Strategy, Queued Flow Processing Strategy, Asynchronous Flow Processing Strategy, Thread Per Processing Strategy, Queued Asynchronous Flow Processing Strategy, Non-blocking Flow Processing Strategy, Custom Processing Strategy, Rollback Exception Handling.
22) What is caching and why to use it?
Answer ) Caching is a concept with is used to store frequently used data in the memory, file system or database which saves processing time and load if it would have to be accessed from original source location every time. know more at Mulesoft training course
