What is the significance of following a RESTful design pattern in web service development?
- High resource utilization
- Stateless communication
- Tight coupling between components
- XML-based communication
Following a RESTful design pattern in web service development is significant for achieving stateless communication, promoting scalability and simplicity.
For a web service that needs to securely exchange sensitive data with a SOAP-based system, what security implementation is most suitable?
- JWT (JSON Web Tokens)
- OAuth 2.0
- SSL/TLS (Secure Socket Layer/Transport Layer Security)
- WS-Security
WS-Security is a standard for securing SOAP-based web services. It provides a comprehensive set of specifications for securing message integrity, confidentiality, and authentication. When dealing with sensitive data exchange in SOAP, WS-Security is a suitable choice for robust security.
In Docker, what is a 'Dockerfile' used for?
- Configuring container security policies
- Defining the structure and content of a container
- Managing Docker network configurations
- Storing container logs
A Dockerfile is used to define the structure and content of a Docker container, specifying the steps to build the container image.
In terms of API versioning, how does GraphQL differ from REST?
- GraphQL typically doesn't require versioning
- GraphQL uses URL versioning
- REST automatically handles version updates
- REST uses HTTP headers for versioning
GraphQL typically doesn't require versioning due to its flexible schema and ability to request only the needed data.
How does WSDL facilitate the interaction between different web services?
- By enabling user interface creation
- By executing server-side scripts
- By managing database connections
- By providing a standard way to describe the interface and communication protocols
WSDL (Web Services Description Language) facilitates interaction by providing a standardized way to describe the interface and communication protocols of web services. This allows for interoperability between different systems.
_______ is a popular tool used for continuous integration and continuous delivery in web services.
- Docker
- Git
- Jenkins
- Kubernetes
Jenkins is a widely used tool for continuous integration and continuous delivery in the context of web services.
What is the primary difference between HTTP and HTTPS protocols in web services?
- Data Encryption
- Header Formats
- Port Numbers
- Request Methods
The primary difference between HTTP and HTTPS is that HTTPS encrypts data during transmission. It uses protocols like SSL/TLS to secure the communication channel, providing a secure and private connection between the client and the server.
For automated testing, Postman integrates with _______ for continuous delivery.
- Docker
- GitLab
- JIRA
- Jenkins
Postman integrates with Jenkins for continuous delivery in automated testing processes.
For microservices, _______ testing is crucial to ensure each service functions correctly within the larger system.
- Component
- End-to-End
- Regression
- Unit
End-to-End testing for microservices is crucial to ensure that each service functions correctly within the larger system.
How does an API Gateway enhance the functionality of web services?
- Centralized management of API requests
- Database management for web services
- Graphic design for APIs
- Load balancing for web servers
An API Gateway enhances web service functionality by providing centralized management of API requests, including routing, security, and load balancing.
