The _______ protocol is often used in conjunction with SOAP to enable more secure exchanges.
- FTPS
- HTTPS
- SMTPS
- TCP
The HTTPS protocol is often used in conjunction with SOAP to enable more secure exchanges. HTTPS (Hypertext Transfer Protocol Secure) provides a secure communication channel over the internet, ensuring the confidentiality and integrity of data exchanged between clients and services.
Which type of web service is more suitable for asynchronous processing and complex operations?
- JSON-RPC
- REST (Representational State Transfer)
- SOAP (Simple Object Access Protocol)
- XML-RPC
SOAP is more suitable for asynchronous processing and complex operations. It supports features like message queuing and transactions, making it a preferred choice for scenarios where robust communication and coordination are essential.
In token-based authentication, what is the main advantage of using tokens over traditional credentials?
- Compatibility with legacy systems
- Simplicity in implementation
- Stateless nature and scalability
- Strong encryption of credentials
Token-based authentication offers a stateless and scalable solution, as tokens carry the necessary information and reduce the need for server-side storage of session data.
In a scenario involving microservices architecture, why would JWT be preferred over traditional session-based authentication?
- Compatibility with legacy systems
- Simplicity and ease of implementation
- Stateless nature and scalability
- Tight coupling between services
JWT is preferred in microservices architectures due to its stateless nature, making it scalable and efficient. It eliminates the need for centralized session management.
The technique of using _______ tokens can help in preventing CSRF, which is often confused with XSS.
- Anti-CSRF
- HMAC
- JWT
- Session
Using Anti-CSRF tokens is a technique to prevent Cross-Site Request Forgery (CSRF) attacks, often confused with Cross-Site Scripting (XSS).
Which type of encryption is commonly used for securing data in transit?
- AES
- MD5
- RSA
- SSL/TLS
SSL/TLS encryption is commonly used for securing data in transit, providing a secure communication channel over the internet.
How should a web service provider communicate upcoming version deprecations to its clients?
- API Documentation
- Custom Response Headers
- Email Notification
- HTTP Status Codes
Updating the API documentation is an effective way to communicate upcoming version deprecations, providing clear guidance to clients on changes and alternatives.
RESTful web services typically exchange data in which format?
- HTML
- JSON
- XML
- YAML
RESTful web services typically exchange data in JSON (JavaScript Object Notation) format due to its lightweight and easy-to-parse nature, making it suitable for web communication.
What is a breakpoint in the context of debugging web services?
- A connection issue with the web service
- A point in the code where execution pauses for inspection
- A point where the service stops working
- A type of error message
In debugging web services, a breakpoint is a point in the code where execution pauses, allowing developers to inspect variables and step through the code.
A development team is testing a web application under various load conditions. Which approach should they use for best results?
- Acceptance Testing
- Regression Testing
- Stress Testing
- Unit Testing
Stress testing involves testing a system under extreme conditions, helping to identify its robustness and performance under heavy loads.
