A developer is testing a RESTful service's response to invalid input. What is the key aspect to focus on?
- Database schema
- Handling of error codes and messages
- Performance optimization
- User interface design
When testing a RESTful service's response to invalid input, it's crucial to focus on how the service handles error codes and messages to provide meaningful feedback to clients.
During the unit testing of a SOAP web service, what should be the primary consideration when dealing with complex data structures?
- Code modularity
- Minimizing network latency
- Proper serialization and deserialization
- User authentication
When dealing with complex data structures in SOAP web service unit testing, the primary consideration should be ensuring proper serialization and deserialization of data for accurate communication between client and server.
What is the impact of microservices on traditional SOA practices?
- Enhancement of centralized monolithic systems
- Increased complexity and management overhead
- No impact; microservices are a subset of SOA
- Shift towards decentralized and smaller services
Microservices impact traditional SOA practices by shifting towards decentralized and smaller services. While both share common principles, microservices emphasize smaller, independent services that operate autonomously, challenging some aspects of the centralized and monolithic nature associated with traditional SOA practices.
_______ is an XML-based protocol used for exchanging structured information in web services.
- JSON
- SOAP
- WSDL
- XML-RPC
SOAP (Simple Object Access Protocol) is an XML-based protocol used for exchanging structured information in web services.
Token-based authentication is often used in RESTful APIs because it does not maintain _______.
- Cookies
- Persistent Connections
- Server Logs
- Session State
Token-based authentication is preferred in RESTful APIs as it does not require maintaining session state on the server.
Which protocol is commonly used for secure, token-based authentication in web services?
- FTP
- OAuth
- SOAP
- UDP
OAuth is commonly used for secure, token-based authentication in web services, providing a standardized way for third-party applications to obtain limited access to a web service.
A _______ certificate is often used in web services to establish a secure connection between client and server.
- PGP
- SHA-256
- SSL/TLS
- X.509
An X.509 certificate is often used in web services to establish a secure connection between the client and server, providing authentication and encryption.
The concept of _______ in GraphQL allows for real-time data updates, unlike typical REST APIs.
- Notifications
- Observers
- Subscriptions
- Transactions
GraphQL introduces the concept of subscriptions, enabling real-time data updates, a feature not inherent in traditional REST APIs.
For a project requiring extensive API versioning due to frequent updates, which approach is more manageable?
- Header Versioning
- Media Type Versioning
- Query Parameter Versioning
- URI Versioning
Header Versioning is more manageable for extensive API versioning, as it keeps version information separate from the URI, promoting cleaner and more flexible URLs.
A team is testing a web service integrated with several third-party APIs. What strategy should they prioritize for effective integration?
- Mocking third-party APIs for controlled testing
- Relying solely on live third-party API calls
- Skipping integration testing for third-party APIs
- Testing only one third-party API at a time
Mocking third-party APIs allows the team to control the testing environment, ensuring effective and controlled integration testing.
