In REST, what is the significance of resource URIs?
- Determining the server location
- Identifying and accessing resources
- Providing authentication information
- Specifying the message format
Resource URIs in REST play a crucial role in identifying and accessing resources on the server. They form the basis for RESTful interactions.
When integrating with enterprise-level legacy systems, _______ might offer better support compared to _______ due to its standardized protocol.
- GraphQL
- REST
- SOAP
- XML-RPC
When integrating with enterprise-level legacy systems, SOAP might offer better support compared to REST due to its standardized protocol. SOAP (Simple Object Access Protocol) provides a strict set of rules for communication, making it a suitable choice for environments that require high security and reliability.
When unit testing a web service, what is the importance of mocking external dependencies?
- To increase the complexity of tests
- To introduce real-world dependencies
- To isolate the code under test and ensure tests are focused
- To slow down the testing process
Mocking external dependencies is crucial to isolate the code under test, allowing focused testing without relying on real-world external factors.
In the context of web services, why is it crucial to handle errors gracefully?
- Enhances performance
- Improves user experience
- Introduces security vulnerabilities
- Reduces code complexity
Handling errors gracefully in web services is crucial as it improves the user experience by providing meaningful error messages, making the system more user-friendly.
How does SOAP ensure security in its message transmission?
- Encryption and digital signatures
- IP address filtering
- Obfuscation of message content
- Token-based authentication
SOAP ensures security through techniques like encryption and digital signatures, providing confidentiality and integrity during message transmission.
To enhance the discoverability of a RESTful service, _______ can be used to describe the API.
- GraphQL
- JSON-RPC
- OpenAPI Specification
- XML Schema
To enhance the discoverability of a RESTful service, the OpenAPI Specification can be used. It provides a standard way to describe and document RESTful APIs, making them more accessible and easily understandable for developers.
A company needs to implement a secure API with mobile client support. Which authentication method is preferable?
- API Key Authentication
- Basic Authentication
- HMAC Authentication
- OAuth 2.0
OAuth 2.0 is a preferred authentication method for securing APIs, especially when mobile client support is required. It provides a token-based approach for secure access.
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.
