In OAuth 2.0, _______ is a crucial component for secure authorization.
- Access Token
- Authorization Code
- OpenID Connect
- Refresh Token
In OAuth 2.0, the Authorization Code is a crucial component for secure authorization. It is part of the authorization flow, where the client redirects the user to the authorization server, and upon approval, the server issues an authorization code. This code is then exchanged for an access token, enhancing the security of the authorization process.
Which type of testing focuses on the interaction between two modules of a web service?
- Integration Testing
- Regression Testing
- System Testing
- Unit Testing
Integration testing is specifically designed to focus on the interaction between different modules of a web service.
In performance testing of APIs, how does Postman differ from SOAP UI?
- Emphasizes simplicity and ease of use
- Includes scriptless automation for performance tests
- Provides detailed protocol analysis
- Supports distributed load testing
Unlike Postman, SOAP UI supports distributed load testing, allowing users to simulate realistic scenarios and assess the performance of APIs under varying conditions.
How does XML differ from JSON in terms of data structure representation?
- Graph-based structure
- Hierarchical structure
- Sequential structure
- Tree structure
XML represents data in a hierarchical structure, allowing nested elements and complex relationships. In contrast, JSON uses a tree structure, making it more straightforward with a sequential and easily readable format. Understanding these differences is crucial when choosing the appropriate format for data representation.
For a web service handling health information, which compliance standard takes precedence in the U.S.?
- FERPA (Family Educational Rights and Privacy Act)
- GDPR (General Data Protection Regulation)
- HIPAA (Health Insurance Portability and Accountability Act)
- PCI DSS (Payment Card Industry Data Security Standard)
In the U.S., web services handling health information must comply with HIPAA, which ensures the security and privacy of healthcare data.
When designing a secure API that requires user-specific data access, which security standard is most appropriate?
- JWT (JSON Web Tokens)
- OAuth 2.0
- OpenID Connect
- SAML (Security Assertion Markup Language)
OAuth 2.0 is a widely used security standard for securing APIs, especially when user-specific data access is needed. It provides a token-based authentication and authorization mechanism, allowing controlled access to resources without exposing user credentials.
Which web service protocol is known for its lightweight nature and ease of use through HTTP?
- CORBA
- REST
- SOAP
- XML-RPC
REST is known for its lightweight nature and ease of use through HTTP. RESTful services use simple and standard HTTP methods for communication, making them widely adopted for building scalable and interoperable web applications.
How does REST handle state between client and server?
- Cookies for maintaining state
- Persistent server-side storage
- Session-based communication
- Stateless communication
REST relies on stateless communication, meaning each request from a client to a server contains all the information needed to understand and fulfill the request. This enhances scalability and simplicity.
_______ is a protocol that can be used with SOAP for reliable message delivery.
- FTP
- HTTP
- SMTP
- WS-ReliableMessaging
WS-ReliableMessaging is a protocol used with SOAP to ensure reliable and guaranteed message delivery in web services communication.
In basic terms, what does decryption do?
- Converts encrypted data back to its original form
- Generates random encryption keys
- Increases data complexity
- Secures network connections
Decryption, in basic terms, reverses the process of encryption, converting encrypted data back to its original, readable form.
