A web service has to be updated without disrupting existing clients. What versioning strategy should be used?
- Header Versioning
- Media Type Versioning
- Query Parameter Versioning
- URI Versioning
Header Versioning involves specifying the version information in the HTTP headers, allowing seamless updates without disrupting existing clients.
When integrating third-party APIs into a web service, what is a crucial factor to ensure seamless operation?
- Heavy data payload
- Minimal error handling
- Public availability
- Rate limiting and authentication
Ensuring rate limiting and proper authentication when integrating third-party APIs is crucial for security and preventing abuse.
In a scenario where API endpoints change frequently, how can Postman assist in maintaining test accuracy?
- Change the test scripts each time
- Rely on manual testing
- Update the documentation only
- Use variables and environments
Postman allows the use of variables and environments, helping maintain test accuracy even when API endpoints change frequently.
What is the primary objective of performance testing in web services?
- Analyzing database structure
- Assessing system responsiveness and stability under varying loads
- Checking code syntax errors
- Designing user interfaces
Performance testing in web services aims to evaluate system responsiveness and stability under different loads, ensuring optimal performance.
What role does contract testing play in integration testing of web services?
- Only applicable in monolithic architectures
- Testing individual services in isolation
- Validating user interfaces
- Verifying agreements between services
Contract testing involves verifying the contracts or agreements between services, ensuring they interact as expected.
SOAP messages are typically transported using _______ protocol.
- HTTP
- SMTP
- TCP
- UDP
SOAP messages are commonly transported over HTTP protocol, making them platform-independent and easily accessible.
Achieving _______ compliance is critical for web services handling medical data.
- Privacy
- Regulatory
- Security
- Standard
Web services handling medical data must achieve regulatory compliance to meet legal requirements and ensure data security.
OAuth provides _______ as a way to grant limited access to an HTTP service.
- Cookies
- Headers
- Sessions
- Tokens
OAuth provides tokens as a way to grant limited access to an HTTP service. Tokens are issued after successful authentication and authorization and are used to access protected resources without exposing the user's credentials.
________ is a common vulnerability in HTTP not found in HTTPS due to its lack of encryption.
- Cross-Site Scripting (XSS)
- Man-in-the-Middle Attacks
- Plain Text Transmission
- SQL Injection
Plain text transmission is a common vulnerability in HTTP, where data is sent without encryption. In HTTPS, the lack of encryption is mitigated, as the TLS protocol encrypts data during transmission, making it challenging for attackers to intercept and understand the content. This enhances security by preventing unauthorized access to sensitive information.
What distinguishes a RESTful service from a SOAP-based service?
- Complex messaging patterns and strong typing
- Heavy use of XML for message format
- Requires a service description language
- Stateless communication and simplicity
RESTful services are characterized by stateless communication, emphasizing simplicity and scalability. Unlike SOAP, they don't rely on complex messaging patterns.
