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.
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.
In the context of web services, what does UDDI provide?
- Communication protocol for web services
- Data serialization for web services
- Directory services for discovering web services
- Security for web services
UDDI (Universal Description, Discovery, and Integration) provides directory services for discovering web services, allowing applications to find and invoke web services dynamically.
How does HTTP/2 improve performance compared to HTTP/1.1 in web services?
- All of the above
- Compression
- Multiplexing
- Prioritization
HTTP/2 improves performance through features like multiplexing, compression, and prioritization. These enhancements lead to more efficient data transfer, reduced latency, and optimized resource utilization, providing a significant boost in web services performance compared to the older HTTP/1.1 protocol.
WS-Security is a standard that applies security at the _______ level.
- Application
- Message
- Network
- Transport
WS-Security is a standard that applies security at the message level. It ensures the confidentiality, integrity, and authentication of messages exchanged between web services by embedding security information directly within the SOAP message.
What is the primary difference in the way data is retrieved between GraphQL and REST?
- Both retrieve data in the same way
- GraphQL retrieves fixed data structures, while REST allows clients to request only the data they need
- None of the above
- REST retrieves fixed data structures, while GraphQL allows clients to request only the data they need
GraphQL allows clients to specify the exact data they need, minimizing over-fetching or under-fetching, while REST returns fixed data structures.
What is the primary purpose of UDDI in web services?
- Creating user interfaces
- Discovering and publishing web services
- Managing databases
- Running server-side scripts
UDDI (Universal Description, Discovery, and Integration) is primarily used for discovering and publishing web services, allowing businesses to find and interact with each other's services.
_______ is a technique used in Microservices to ensure that all services are updated simultaneously.
- Blue-Green Deployment
- Canary Deployment
- Continuous Integration
- Feature Toggling
Canary Deployment is a technique in Microservices where updates are rolled out gradually to ensure simultaneous updates of all services.
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.
________ 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.
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.
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.
