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.
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 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.
In multi-factor authentication, the use of a device the user owns is considered as _______.
- Authenticator
- Biometric
- Smart Card
- Token
In multi-factor authentication, a device the user owns, such as a smartphone with a security app, is often used as an authenticator.
For SOAP services, the _______ element contains detailed error information.
In SOAP services, the element contains detailed error information.
What is the primary challenge when maintaining backward compatibility in web service versioning?
- Creating new features without any changes
- Ignoring compatibility issues
- Modifying existing functionality without breaking existing clients
- Removing old features without notice
The primary challenge in maintaining backward compatibility is modifying existing functionality without breaking existing clients, ensuring a smooth transition to new versions.
In cloud-based web services, _______ allows the management of infrastructure through code.
- Cloud Automation
- Cloud Orchestration
- Code Infrastructure Management
- Infrastructure as Code (IaC)
Infrastructure as Code (IaC) enables the management of cloud infrastructure through code, providing automation and consistency.
In REST, how are different versions of a resource typically handled?
- By embedding the version information in the resource representation
- By using query parameters to specify the version in each request
- Through URI versioning, where the version is included in the resource's URI
- Through request headers indicating the desired version
Different versions of a resource in REST are commonly handled through URI versioning, where the version is explicitly mentioned in the resource's URI. This approach helps in maintaining backward compatibility.
In a distributed system, API Gateways facilitate _______ between different microservices.
- Authentication
- Authorization
- Communication
- Service discovery
API Gateways play a crucial role in facilitating communication between different microservices in a distributed system, ensuring seamless interaction and coordination.
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.
_______ 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.
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.
