_______ 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.
Which U.S. law is focused on health data protection in web services?
- CAN-SPAM Act
- COPPA (Children's Online Privacy Protection Act)
- DMCA (Digital Millennium Copyright Act)
- HIPAA (Health Insurance Portability and Accountability Act)
HIPAA is the U.S. law focused on protecting health data in web services, ensuring the security and confidentiality of patient information.
In a high-concurrency scenario, what aspect of web services is critical to evaluate?
- Database Schema
- Scalability
- Security
- User Interface Design
In high-concurrency scenarios, scalability is critical to ensure the web service can handle increased load efficiently.
_______ is a key technique in simulating third-party services in microservices architecture.
- Service Integration
- Service Mesh
- Service Orchestration
- Service Virtualization
Service virtualization is a technique used to simulate third-party services in microservices architecture for testing purposes.
What is the primary benefit of using asynchronous communication in web services?
- Improved scalability by handling multiple requests concurrently
- Increases latency in communication
- Reduces the need for security measures
- Simplifies the development process
Asynchronous communication in web services improves scalability by handling multiple requests concurrently, leading to better performance and resource utilization.
In web services, what advantage does JSON have over XML in mobile applications?
- Binary encoding support
- Extensive schema support
- Lightweight data interchange format
- Strongly typed structure
JSON has an advantage over XML in mobile applications due to its lightweight data interchange format. The reduced overhead in JSON results in faster data transmission, making it more suitable for mobile devices with limited bandwidth and processing power, contributing to improved overall performance in mobile web services.
The concept of _______ is crucial in RESTful services to ensure that the client and server are loosely coupled.
- CORS
- CRUD
- HATEOAS
- RPC
The concept of HATEOAS (Hypertext As The Engine Of Application State) is crucial in RESTful services. It emphasizes providing hypermedia links in the response, allowing the client to navigate the application and discover available actions dynamically. This ensures loose coupling between the client and server.
In WSDL, the _______ element specifies the address of the web service.
In WSDL, the element specifies the address of the web service. It contains network-specific information (such as the URL) for accessing the service.
________ is a common practice in integration testing to verify interactions with external services.
- Faking
- Mocking
- Stacking
- Stubbing
Mocking is a common practice in integration testing to simulate interactions with external services for thorough testing.
In terms of extensibility and integration with existing infrastructure, what is a key advantage of SOAP over REST?
- REST allows for flexible message formats
- REST is more suited for integrating with existing infrastructure
- SOAP is limited in its ability to integrate with existing systems
- SOAP provides a standardized and rigid structure for messages
A key advantage of REST over SOAP in terms of extensibility and integration is its flexibility in message formats. RESTful web services can use various formats like JSON, XML, etc., making it easier to adapt and integrate with existing systems that may use different data representations. SOAP, on the other hand, has a standardized and rigid message structure, which may pose challenges in certain integration scenarios.
