A developer is facing an issue where a web service works locally but fails in production. What should be the primary focus of their debugging?
- Browser compatibility
- Code syntax errors
- Database connection issues
- Network differences between local and production environments
When a web service works locally but fails in production, network differences between the two environments should be a primary focus for debugging.
How does JWT (JSON Web Token) enhance security in stateless authentication?
- It carries self-contained claims in a token
- It encrypts the entire HTTP payload
- It includes encrypted session data
- It provides a secure channel for data transfer
JWT enhances security in stateless authentication by carrying self-contained claims in a token, reducing the need for constant server-side storage of session data.
In a scenario where an organization is transitioning to cloud-based services, what interoperability factors need to be considered?
- Data formats and APIs compatibility
- Network latency and bandwidth
- Only choosing cloud-native services
- Restricting access to on-premise systems
Transitioning to cloud-based services requires consideration of factors such as data formats and APIs compatibility. Ensuring that data formats align and APIs are interoperable is crucial for seamless communication between on-premise and cloud systems. Ignoring these factors could lead to integration challenges and hinder the organization's ability to fully leverage the benefits of cloud services.
What is the primary purpose of JWT in web services?
- Authentication and Information Exchange
- File storage
- Graphic design in web development
- Wireless communication
JWT (JSON Web Token) is primarily used for authentication and secure information exchange between parties.
_______ is a critical feature of API Gateways for managing the lifecycle of APIs.
- Compression
- Encryption
- Monitoring
- Versioning
Versioning is a critical feature of API Gateways as it helps in managing the lifecycle of APIs by allowing different versions to coexist and ensuring backward compatibility.
The concept of _______ in REST involves making the data format of a resource's representation include links to possible actions and next steps.
- Dynamic Binding
- Hypermedia
- Linked Resources
- Resource State Transfer
HATEOAS (Hypermedia As The Engine Of Application State) involves including hypermedia links in the representation of a resource, allowing clients to navigate the application's functionality.
Which layer of the OSI model does SSL/TLS primarily operate at?
- Application Layer
- Data Link Layer
- Network Layer
- Transport Layer
SSL/TLS primarily operates at the Transport Layer of the OSI model, providing secure communication between devices.
In REST, client-server interactions are stateless, each request from the client to the server must contain all the information needed to understand the request, and cannot take advantage of any stored _______ on the server.
- Context
- Information
- Session
- State
In REST, the statelessness principle means that each request should contain all the information needed to understand and process the request, and no information is stored on the server between requests.
Mock services are typically used in which phase of the software development life cycle?
- Deployment
- Development
- Maintenance
- Requirements
Mock services are primarily used in the development phase of the software development life cycle to simulate the behavior of real services during testing.
The principle of _______ is crucial in designing scalable and resilient web services.
- Code obfuscation
- Loose coupling
- Strong typing
- Tight coupling
The principle of loose coupling is crucial in designing scalable and resilient web services, allowing components to evolve independently.
