Which HTTP header is typically used for passing authentication tokens in RESTful services?
- Authentication
- Authorization
- Security
- Token
The Authorization header is commonly used for passing authentication tokens in RESTful services.
In terms of interoperability, what is a significant advantage of RESTful services over SOAP-based services?
- Lightweight and easy to integrate
- Optimizes complex data processing tasks
- Provides advanced security features
- Supports remote procedure calls (RPC)
A significant advantage of RESTful services in terms of interoperability is their lightweight nature and ease of integration. RESTful services use standard HTTP methods and simple data formats, making them more accessible and adaptable across different platforms. This simplicity promotes interoperability, especially in scenarios where resource constraints or diverse technology stacks are prevalent.
SOAP is based on which standard communication protocol?
- HTTP
- SMTP
- TCP
- XML
SOAP (Simple Object Access Protocol) is based on XML, which serves as the standard communication protocol. XML provides a platform-independent and extensible format for encoding data, ensuring interoperability between different systems and programming languages.
In a continuous deployment setup, _______ is used to automate the deployment of web services.
- Ansible
- Docker
- Jenkins
- Kubernetes
Ansible is often used in continuous deployment setups to automate the deployment of web services, ensuring efficient and reliable deployment processes.
How does GDPR affect web services that handle personal data of EU citizens?
- It encourages unlimited data sharing
- It mandates the use of proprietary encryption algorithms
- It only applies to non-EU citizens
- It requires explicit consent for data processing
GDPR (General Data Protection Regulation) requires explicit consent for processing personal data of EU citizens, emphasizing user privacy and control.
For secure token-based authentication in web services, which encryption technique is most effective?
- AES (Advanced Encryption Standard)
- DES (Data Encryption Standard)
- HMAC (Hash-based Message Authentication Code)
- RSA (Rivest–Shamir–Adleman)
HMAC (Hash-based Message Authentication Code) is commonly used for secure token-based authentication in web services, providing an effective way to ensure data integrity and authentication.
How does an API Gateway assist in implementing authentication and authorization for APIs?
- It centralizes authentication and authorization logic, acting as a security guard for APIs
- It encrypts the data exchanged between APIs
- It only authenticates users and does not handle authorization
- It provides a platform for developing APIs but does not handle authentication and authorization
An API Gateway assists by centralizing authentication and authorization logic, serving as a security layer for APIs, ensuring secure access and controlled permissions.
_______ is a protocol used in SAML to pass the authentication and authorization decisions.
- Secure Authentication Protocol
- Secure Authorization Markup Language
- Security Assertion Markup Language
- Simple Authentication and Authorization Protocol
SAML uses the Security Assertion Markup Language protocol to pass authentication and authorization decisions.
_______ is used in REST to request the server to accept the entity enclosed in the request as a new subordinate of the web resource.
- DELETE
- PATCH
- POST
- PUT
In REST, the POST method is used to request the server to accept the entity enclosed in the request as a new subordinate of the web resource. It is often used for creating a new resource or submitting data to be processed, and the server responds with the details of the newly created resource.
Kubernetes is primarily used for what purpose in containerization?
- Database management
- Front-end development
- Machine learning
- Orchestration and management of containers
Kubernetes is mainly used for orchestrating and managing containers, ensuring efficient deployment and scaling.
In the context of web services, serverless computing primarily means what?
- Direct server control for applications
- Graphic design for server architecture
- Load balancing for web servers
- Running applications without managing server infrastructure
Serverless computing in web services means running applications without managing server infrastructure, allowing developers to focus on code rather than server management.
REST APIs commonly use which method to retrieve data without affecting the resource?
- DELETE
- GET
- POST
- PUT
REST APIs commonly use the GET method to retrieve data without affecting the resource, emphasizing the idempotent nature of the operation.
