How does unit testing contribute to the continuous integration process of web services?
- By increasing the likelihood of bugs in production
- By providing rapid feedback on code changes
- By skipping the testing phase
- By slowing down the integration process
Unit testing contributes to continuous integration by providing rapid feedback on code changes, helping catch issues early in the development process.
In SOA, _______ is a common approach for integrating heterogeneous systems.
- Enterprise Service Bus (ESB)
- Representational State Transfer (REST)
- Service-Oriented Architecture
- Web Service Description Language (WSDL)
In Service-Oriented Architecture (SOA), the Enterprise Service Bus (ESB) is a common approach for integrating heterogeneous systems. The ESB facilitates communication and integration between different services and applications in a loosely coupled manner.
Which HTTP method is commonly used for creating resources in REST?
- DELETE
- GET
- POST
- PUT
The HTTP method commonly used for creating resources in REST is POST. It is used to submit data to be processed to a specified resource.
In WSDL, the term 'binding' refers to what?
- The association between the abstract interface and a concrete protocol
- The definition of complex data types
- The process of connecting to a database
- The specification of user interfaces
In WSDL, 'binding' refers to the association between the abstract interface and a concrete protocol. It defines how the web service will be accessed over the network.
What is the role of a namespace in XML-based web service versioning?
- Avoid naming conflicts in different versions
- Enhance security in web service communication
- Provide a unique identifier to each version
- Simplify XML document structure
A namespace in XML-based web service versioning plays a crucial role in avoiding naming conflicts between different versions, ensuring clarity and preventing ambiguity.
When designing a web service for a healthcare application, what encryption standards must be considered for compliance?
- FERPA
- GDPR
- HIPAA
- PCI DSS
Healthcare applications must consider compliance with the Health Insurance Portability and Accountability Act (HIPAA) for encryption standards.
What is the main advantage of using elliptic curve cryptography over RSA in web services?
- Faster decryption speed
- Greater compatibility with legacy systems
- Improved resistance to quantum attacks
- Smaller key sizes with equivalent security
Elliptic curve cryptography offers the advantage of providing equivalent security with smaller key sizes, making it more efficient for resource-constrained environments like web services.
What is the primary goal of integration testing in web services?
- To ensure the security of the web service
- To test the user interface of the web service
- To validate the interaction between integrated components
- To verify that the individual units of code work correctly
Integration testing in web services primarily focuses on verifying the interaction between integrated components to ensure the smooth functioning of the system.
Which of these is not a typical approach to handling errors in RESTful services?
- Handling errors through HTTP headers
- Redirecting to a generic error page
- Returning detailed error messages in response
- Using appropriate HTTP status codes
Redirecting to a generic error page is not a typical approach to handling errors in RESTful services.
What is the primary architectural constraint of a RESTful web service?
- Scalability
- Security
- Session Management
- Statelessness
The primary architectural constraint of a RESTful web service is statelessness. This means that each request from a client contains all the information needed to understand and fulfill the request, and no session state is stored on the server between requests.
