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.
In REST, how are different versions of a resource typically handled?
- By embedding the version information in the resource representation
- By using query parameters to specify the version in each request
- Through URI versioning, where the version is included in the resource's URI
- Through request headers indicating the desired version
Different versions of a resource in REST are commonly handled through URI versioning, where the version is explicitly mentioned in the resource's URI. This approach helps in maintaining backward compatibility.
In cloud-based web services, _______ allows the management of infrastructure through code.
- Cloud Automation
- Cloud Orchestration
- Code Infrastructure Management
- Infrastructure as Code (IaC)
Infrastructure as Code (IaC) enables the management of cloud infrastructure through code, providing automation and consistency.
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.
How does SOA contribute to business agility and process optimization?
- By enabling modular and reusable services
- By enforcing rigid business processes
- By limiting flexibility in system design
- By prioritizing technology over business needs
SOA contributes to business agility and process optimization by enabling the development of modular and reusable services. This allows organizations to adapt quickly to changing business requirements, streamline processes, and achieve greater flexibility in designing and implementing solutions.
For secure API access, _______ is a protocol for delegating authorization.
- LDAP
- OAuth
- SAML
- SSL
OAuth is a protocol commonly used for delegating authorization in the context of secure API access.
In a scenario where an organization needs to expose different APIs to various external clients, what feature of API Gateways is most beneficial?
- API Versioning
- Authentication and Authorization
- Rate Limiting
- Request Logging
API Versioning in API Gateways is most beneficial when an organization needs to expose different APIs to various external clients, allowing for smooth evolution and backward compatibility.
