How does a RESTful service maintain its statelessness?
- Stateless communication
- Through client sessions
- Using cookies for state
- Via server-side sessions
RESTful services maintain statelessness by not storing client state on the server between requests. Each request from a client contains all the information needed to understand and process the request.
_______ is essential for ensuring web services comply with legal and ethical standards.
- Authentication
- Authorization
- Compliance
- Encryption
Compliance is essential for ensuring that web services adhere to legal and ethical standards.
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.
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.
A comprehensive error handling strategy in web services should include _______ to track and analyze errors over time.
- Authentication
- Caching
- Load Balancing
- Logging and Monitoring
A comprehensive error handling strategy in web services includes logging and monitoring to track and analyze errors over time.
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.
