How does Perfect Forward Secrecy (PFS) enhance TLS in web services?
- Generates a new key for each session, ensuring that even if one session's key is compromised, others remain secure
- Implements rotating keys only for high-priority transactions
- Uses a single, static key for all sessions, simplifying key management
- Utilizes public keys for encryption without the need for private keys
Perfect Forward Secrecy (PFS) enhances TLS by generating a new key for each session, providing stronger security as even if one key is compromised, others remain secure.
To debug a deadlock situation in a web service, a developer might use a _______.
- Debugger
- Logger
- Profiler
- Tracer
Debugging tools are useful for identifying and resolving deadlock situations in web services.
A development team needs to build an API for a highly dynamic application with many changing data requirements. Which API style should they prefer?
- GraphQL
- REST
- RPC
- SOAP
GraphQL is well-suited for dynamic applications with changing data requirements, as it allows clients to request only the data they need.
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.
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.
