In a RESTful architecture, _______ is used to indicate the desired action on a resource.
- CORBA
- HTTP Methods
- SOAP
- WebSockets
In a RESTful architecture, HTTP Methods (such as GET, POST, PUT, DELETE) are used to indicate the desired action on a resource. Each HTTP method corresponds to a specific operation on the resource, contributing to the stateless and resource-centric nature of RESTful services.
To simulate the behavior of real components in a web service, unit tests often use _______.
- Actual data
- Mock objects
- Random inputs
- Sample APIs
In unit testing, mock objects are commonly used to simulate the behavior of real components and isolate the code being tested.
Why is HTTPS considered more secure than HTTP for web services?
- Better Error Handling
- Data Encryption
- Faster Transmission
- Lower Bandwidth Consumption
HTTPS is considered more secure than HTTP because it encrypts data, ensuring that sensitive information transmitted between the client and server is secure from eavesdropping and tampering. This encryption enhances the confidentiality and integrity of data, making it a more secure choice for web service communication.
A best practice in security for web services is to use _______ for secure data transmission.
- FTPS
- HTTPS
- SSH
- TLS
HTTPS (Hypertext Transfer Protocol Secure) is a best practice for secure data transmission in web services, providing encryption and data integrity.
_______ is a key factor in achieving scalability and flexibility in SOA.
- Centralized Architecture
- Data Encryption
- Loose Coupling
- Object-Relational Mapping (ORM)
Loose coupling is a key factor in achieving scalability and flexibility in Service-Oriented Architecture (SOA). It allows services to operate independently, promoting modularity and ease of updates without affecting the entire system. Loose coupling enhances adaptability and scalability in SOA.
In web security, XSS stands for what?
- Cross-Site Scripting
- Extended Server Software
- External System Support
- XML Security Services
XSS stands for Cross-Site Scripting, a type of security vulnerability where attackers inject malicious scripts into web pages viewed by other users.
In advanced unit testing, _______ is used to ensure that the web service can handle various types of failure scenarios.
- Code coverage
- Fault injection
- Load testing
- Static analysis
Fault injection is used in advanced unit testing to simulate various failure scenarios and ensure the robustness of the web service.
To identify the root cause of an error, developers often rely on _______ files generated by the web service.
- Configuration
- Database
- Log
- XML
Developers often rely on log files generated by the web service to identify the root cause of errors.
How should a unit test be structured when testing a web service for compliance with security protocols?
- Focus solely on input validation
- Ignore encryption and focus on decryption
- Include test cases for authentication and authorization
- Prioritize performance testing
When testing a web service for compliance with security protocols, the unit test should be structured to include test cases for authentication and authorization to ensure secure access to the service.
How does the implementation of DevOps practices impact the lifecycle of web services?
- Accelerated development and deployment cycles
- Increased manual interventions in deployment
- Limited collaboration between development and operations teams
- Reduced automation in testing
Implementation of DevOps practices accelerates development and deployment cycles, promoting collaboration and automation throughout the lifecycle of web services.
How does Microservices Architecture enhance deployment?
- Deployment as a single unit
- Independent deployment of services
- Limited deployment options
- Manual deployment for all services at once
Microservices Architecture allows for independent deployment of services, enabling more flexibility and agility in the deployment process.
GraphQL is mainly used in web services for what purpose?
- Data storage in databases
- Efficient data querying and manipulation
- Real-time video streaming
- Voice recognition
GraphQL is used for efficient querying and manipulation of data, allowing clients to request only the data they need.
