When testing a highly secure SOAP service, which features of SOAP UI would be most beneficial?
- HTTP Basic Authentication
- JWT Authentication
- OAuth Authorization
- WS-Security

The practice of using fake services in place of real ones during testing is known as _______.
- Continuous integration
- Dependency injection
- Service virtualization
- Test-driven development
The practice of using fake services in place of real ones during testing is known as service virtualization, helping developers simulate various scenarios.
In WS-Security, what is the role of XML Encryption?
- Compressing the XML document
- Encrypting specific elements in the XML
- Encrypting the entire XML document
- Signing the XML document
In WS-Security, XML Encryption is used to encrypt specific elements within an XML document. This selective encryption enhances security by allowing sensitive data to be protected while leaving other parts of the document intact. It provides a granular approach to securing information in transit within web services.
XML uses _______ to define the structure of the data it encloses.
- Attributes
- Brackets
- Elements
- Tags
XML uses tags to define the structure of the data it encloses. Tags are the building blocks of an XML document, enclosing data and providing a hierarchical structure that is easily readable and understandable.
A web service is experiencing increased load and slowing down. What debugging strategy is most appropriate to identify bottlenecks?
- Code review
- Performance profiling
- Security testing
- Unit testing
Performance profiling is an appropriate debugging strategy to identify bottlenecks in a web service experiencing increased load and slowing down. It helps analyze the performance of different components.
The _______ protocol is deprecated in favor of TLS for securing web services.
- FTP
- HTTP
- SMTP
- SSL
The SSL (Secure Sockets Layer) protocol is deprecated in favor of TLS (Transport Layer Security) for securing web services.
RESTful APIs use HTTP _______ to perform operations on resources.
- Actions
- Methods
- Requests
- Verbs
RESTful APIs use HTTP methods, also known as HTTP verbs, to perform operations on resources. Common methods include GET, POST, PUT, DELETE, etc.
The use of _______ ensures that web services can be accessed regardless of programming language or platform.
- CORBA (Common Object Request Broker Architecture)
- HTTP (Hypertext Transfer Protocol)
- URI (Uniform Resource Identifier)
- WSDL (Web Services Description Language)
The use of URI (Uniform Resource Identifier) ensures that web services can be accessed regardless of programming language or platform. URIs provide a standardized way to identify and locate resources on the web, promoting a language-agnostic and platform-independent approach.
