In terms of web services, what is a major security risk associated with HTTP that is mitigated by HTTPS?
- Insufficient server resources
- Lack of encryption for data in transit
- Limited support for RESTful APIs
- Vulnerability to SQL injection attacks
A major security risk associated with HTTP is the lack of encryption for data in transit. HTTPS addresses this concern by encrypting the communication between clients and servers, ensuring that sensitive information is secure and protected from unauthorized access or interception by malicious entities.
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.
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.
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 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.
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.
When handling XML in web services, what is the purpose of a schema?
- Controlling user authentication
- Defining the structure and rules for XML documents
- Formatting XML for display
- Storing XML files on a server
A schema in web services is used to define the structure and rules for XML documents.
For real-time data transmission with minimal overhead, _______ is often preferred over _______ due to its simplicity.
- HTTP/1.1
- MQTT
- WebSocket
- WebSockets
For real-time data transmission with minimal overhead, WebSocket is often preferred over HTTP/1.1 due to its simplicity. WebSockets provide a full-duplex communication channel, enabling low-latency, bidirectional data exchange between the client and server, making it suitable for real-time applications such as chat or financial trading.
