What is the primary purpose of authentication in web services?
- Enhancing the visual appeal of web applications
- Monitoring network traffic
- Optimizing database queries
- Verifying the identity of users or systems accessing the service
Authentication in web services is primarily about verifying the identity of users or systems accessing the service, ensuring that only authorized entities can interact with it.
In a scenario where different development teams are working on separate modules of a web service, how should integration testing be approached?
- Conducting integration testing in a random order
- Conducting integration testing only after all modules are complete
- Incremental integration testing, starting with individual modules
- Skipping integration testing for individual modules
Incremental integration testing, starting with individual modules, helps identify issues early and ensures smoother integration of different modules.
What role does Kubernetes play in the management of containerized services?
- Database management for containerized services
- Graphic design for containerized services
- Load balancing for web servers
- Orchestration and scaling of containerized applications
Kubernetes is used for the orchestration and scaling of containerized applications, managing deployment, scaling, and operational tasks.
In web service security, what does authorization determine?
- Encryption methods for data transmission
- IP addresses of connected clients
- Permissions and access control for authenticated users
- Quality of service metrics
Authorization in web service security determines the permissions and access control for authenticated users, specifying what actions they are allowed to perform.
When designing a secure API that requires user-specific data access, which security standard is most appropriate?
- JWT (JSON Web Tokens)
- OAuth 2.0
- OpenID Connect
- SAML (Security Assertion Markup Language)
OAuth 2.0 is a widely used security standard for securing APIs, especially when user-specific data access is needed. It provides a token-based authentication and authorization mechanism, allowing controlled access to resources without exposing user credentials.
Which web service protocol is known for its lightweight nature and ease of use through HTTP?
- CORBA
- REST
- SOAP
- XML-RPC
REST is known for its lightweight nature and ease of use through HTTP. RESTful services use simple and standard HTTP methods for communication, making them widely adopted for building scalable and interoperable web applications.
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.
_______ 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.
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.
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.
