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.
________ 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.
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.
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.
