To update a resource partially, the HTTP method _____ is often used.
- DELETE
- PATCH
- POST
- PUT
To update a resource partially, the HTTP method "PATCH" is often used. The "PATCH" method is used to apply partial modifications to a resource, making it suitable for updating specific fields or properties of a resource without affecting the entire resource.
Keeping API keys secure is important to prevent unauthorized ______ to sensitive data.
- Access
- Authentication
- Encryption
- Request
Keeping API keys secure is important to prevent unauthorized access to sensitive data. If an API key is compromised, it can lead to unauthorized access to the protected resources.
How does GraphQL handle real-time data and subscriptions?
- By using WebSocket connections
- Through frequent polling of the server
- By establishing direct database connections
- Using long-polling techniques
GraphQL handles real-time data and subscriptions using WebSocket connections. This allows the server to push data updates to clients, providing real-time capabilities. WebSocket connections are more efficient and responsive compared to frequent polling (Option B) or long-polling (Option D). Direct database connections (Option C) are not typically used due to security and scalability concerns.
Tools like Swagger are used to create ________ for APIs, making it easier for developers to understand and use them.
- Authentication
- Authorization
- Documentation
- Testing
Tools like Swagger are used to create documentation for APIs, making it easier for developers to understand and use them. API documentation generated by Swagger provides clear information about the API endpoints, request and response formats, and usage examples, helping developers work with the API effectively.
What is the purpose of load testing for APIs?
- To assess API functionality
- To check the API's color
- To evaluate API security
- To measure API performance
The purpose of load testing for APIs is to measure the performance and responsiveness of an API under different levels of demand. This helps identify bottlenecks and ensure the API can handle high loads without degrading performance.
How does REST differ from SOAP in terms of flexibility and standards enforcement?
- Both REST and SOAP have the same level of flexibility and standards.
- REST enforces strict standards, while SOAP is flexible.
- REST is more flexible and has fewer standards.
- SOAP is more flexible and has fewer standards.
REST (Representational State Transfer) is generally considered more flexible than SOAP (Simple Object Access Protocol). REST allows developers to choose how they structure their API, while SOAP enforces strict standards and XML-based message formats. This flexibility in REST can make it more suitable for various use cases.
Imagine you are designing an API for a healthcare system. How would you implement RBAC to ensure data privacy and compliance with regulations?
- Role-Based Access Control (RBAC) restricts access to resources based on user roles, ensuring that only authorized users can access sensitive healthcare data.
- Implementing Random Access Control to provide a dynamic, non-deterministic access system.
- Using OAuth for authentication and authorization.
- Using IP whitelisting to control access to the API.
In the context of a healthcare system, implementing Role-Based Access Control (RBAC) is essential to restrict access to sensitive data. RBAC ensures that only authorized users with specific roles can access patient information, contributing to data privacy and regulatory compliance. Other options, such as random access control, OAuth, and IP whitelisting, may not provide the necessary granularity and security required in healthcare settings.
API versioning allows developers to introduce _____ without affecting existing clients.
- Breaking changes
- Bug fixes
- Data storage
- New features
API versioning allows developers to introduce new features without affecting existing clients. It ensures backward compatibility and enables the evolution of the API while maintaining support for older clients.
How can API throttling improve the user experience?
- By displaying more ads to users
- By ensuring consistent and reliable performance
- By increasing the API response time
- By requiring users to complete CAPTCHA challenges
API throttling can improve the user experience by ensuring consistent and reliable performance. It prevents a small number of users or applications from overwhelming the API, which can lead to slowdowns for all users. Throttling ensures a smoother, more predictable user experience, making it a valuable strategy.
Imagine you are tasked with designing an API for a healthcare system. How would you decide between creating a Public, Private, or Partner API, and what factors would influence your decision?
- Based on the API's audience and usage, you'd choose Private to protect sensitive data.
- Choose Partner to grant limited access to trusted organizations.
- Choose Public to encourage open access to health information.
- Choose all three types to provide maximum flexibility.
When designing a healthcare API, you'd consider the audience, data sensitivity, and the level of trust with potential partners. Public, Private, and Partner APIs cater to different needs, and the choice depends on who needs access and the nature of the data being shared. The decision should be based on a thorough analysis of these factors.
