What best practice ensures web services are scalable and maintainable?
- Monolithic architecture
- RESTful architecture
- Spaghetti code
- Tight coupling
Adhering to RESTful architecture is a best practice for ensuring web services are scalable and maintainable, promoting loose coupling and scalability.
In RESTful services, what does the term 'Resource' fundamentally represent?
- Data object
- Database table
- Endpoint
- Web page
In RESTful services, a 'Resource' fundamentally represents an endpoint or a service that can be identified by a unique URI (Uniform Resource Identifier). Resources are entities that the API can act upon, and they can represent data objects, services, or entities that the API interacts with.
_______ framework is preferred for unit testing in Java-based web services.
- JUnit
- MSTest
- NUnit
- TestNG
JUnit is a popular framework for unit testing in Java-based web services.
In a scenario where a web service needs to integrate with multiple third-party services, what architectural style is most effective?
- Event-Driven Architecture
- Microservices architecture
- Monolithic architecture
- Service-Oriented Architecture (SOA)
Microservices architecture is most effective for integrating with multiple third-party services, providing flexibility and modularity.
OAuth is commonly used for what aspect of web service security?
- Authentication
- Authorization
- Encryption
- Session management
OAuth is commonly used for authorization in web service security. It allows secure and controlled access to resources by enabling a token-based authentication mechanism. OAuth is widely employed in scenarios where third-party applications require limited access to a user's resources without exposing sensitive credentials.
A company is transitioning to SOA to improve IT and business alignment. What should be their primary focus in the initial phase?
- Enhancing user interfaces
- Expanding hardware infrastructure
- Identifying key services and their dependencies
- Implementing a new database system
In the initial phase of transitioning to SOA, the primary focus should be on identifying key services and their dependencies. This helps establish a clear understanding of the existing landscape and lays the foundation for a well-organized and effective SOA implementation.
How does the use of TLS in HTTPS impact the security of web services?
- Accelerates data transmission
- Enables cross-origin resource sharing
- Enhances data encryption and integrity
- Facilitates load balancing
The use of TLS in HTTPS enhances the security of web services by providing data encryption and integrity. TLS (Transport Layer Security) ensures that the communication between clients and servers is secure, protecting against eavesdropping and tampering of data during transmission.
Which Azure service is best suited for developing and hosting web applications?
- Azure App Service
- Azure Blob Storage
- Azure Machine Learning
- Azure Virtual Network
Azure App Service is specifically designed for developing and hosting web applications in the Azure cloud.
In terms of bandwidth and resources, which is generally more efficient, SOAP or REST?
- Both have similar efficiency.
- It depends on the specific use case.
- REST
- SOAP
REST is generally more efficient in terms of bandwidth and resources compared to SOAP. RESTful services typically use lightweight formats like JSON, reducing overhead and making them more suitable for bandwidth-constrained environments. SOAP, being XML-based, can be more verbose and resource-intensive, making it less efficient in certain scenarios.
In a DevOps environment, _______ is crucial for ensuring the interoperability of microservices.
- Continuous Deployment
- Continuous Integration
- Continuous Integration and Continuous Deployment
- Continuous Testing
Continuous Testing in a DevOps environment is crucial for ensuring the interoperability of microservices by continuously validating their functionality.
