To simulate the behavior of real components in a web service, unit tests often use _______.
- Actual data
- Mock objects
- Random inputs
- Sample APIs
In unit testing, mock objects are commonly used to simulate the behavior of real components and isolate the code being tested.
In a RESTful architecture, _______ is used to indicate the desired action on a resource.
- CORBA
- HTTP Methods
- SOAP
- WebSockets
In a RESTful architecture, HTTP Methods (such as GET, POST, PUT, DELETE) are used to indicate the desired action on a resource. Each HTTP method corresponds to a specific operation on the resource, contributing to the stateless and resource-centric nature of RESTful services.
What is the primary purpose of encryption in web services?
- Enhancing website design
- Improving network speed
- Optimizing database queries

Integration testing in a CI/CD pipeline often requires DevOps tools to automate test processes.
To test SOAP services, SOAP UI uses a specific type of request known as a _______ request.
- Mock
- POST
- SOAP
- WSDL
To test SOAP services, SOAP UI uses a specific type of request known as a "SOAP" request, which is designed for communication with SOAP-based web services.
In SOAP, the _______ defines the set of operations offered by the service.
- HTTP
- REST
- UDDI
- WSDL
In SOAP, the WSDL (Web Services Description Language) defines the set of operations offered by the service. WSDL is an XML-based language that specifies the functionalities and operations that a SOAP web service provides, enabling clients to understand and interact with the service.
How does XPath enhance the functionality of XML in web services?
