- Authentication
- Authorization
- Encryption
- Input Validation
Input validation is a security principle that involves validating and sanitizing user inputs to prevent security vulnerabilities.
_______ 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 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.
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.
_______ is a technique in web services that dynamically allocates resources to handle varying loads.
- Dynamic resource allocation
- Load balancing
- Resource pooling
- Scalability
Dynamic resource allocation is a technique in web services that dynamically allocates resources to handle varying loads efficiently.
In integration testing, which tool is used to simulate the behavior of web service components?
- Git
- JIRA
- Selenium
- SoapUI
SoapUI is a widely used tool for simulating the behavior of web service components in integration testing.
In RESTful services, a _______ error indicates that the requested resource was not found.
- 200
- 403
- 404
- 500
In RESTful services, a 404 error indicates that the requested resource was not found.
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.
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.
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.
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.
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.
