In Microservices, _______ helps in managing complex inter-service communication patterns.
- API Gateway
- Docker Container
- Load Balancer
- Service Registry
API Gateway is a crucial component in Microservices architecture, managing and routing requests between services, handling complex communication patterns.
REST services typically exchange data in which format?
- HTML
- JSON
- Plain Text
- XML
REST services typically exchange data in JSON (JavaScript Object Notation) format. JSON is a lightweight and readable data interchange format that is easy for both humans to understand and machines to parse, making it well-suited for data exchange in RESTful architectures.
In ensuring interoperability, _______ plays a crucial role in defining security protocols for web services.
- REST
- SOAP
- WSDL
- XML Security
In ensuring interoperability, SOAP (Simple Object Access Protocol) plays a crucial role in defining security protocols for web services. SOAP provides a standardized way to communicate and exchange information between different systems, contributing to secure and reliable interoperability in distributed environments.
In the RESTful API design, the version number is often included in the _______.
- Headers
- Query Parameters
- Request Body
- URL
In RESTful API design, version numbers are often included in the URL to specify the desired API version.
_______ is a design principle in RESTful services that suggests each resource should have a unique identifier.
- Resource Identifier
- Service Endpoint
- Uniform Resource Identifier (URI)
- Universal Resource Locator (URL)
The design principle in RESTful services that suggests each resource should have a unique identifier is the Uniform Resource Identifier (URI). URIs uniquely identify resources and are crucial for addressing and interacting with resources in a RESTful architecture.
The _______ protocol is often used in conjunction with SOAP to enable more secure exchanges.
- FTPS
- HTTPS
- SMTPS
- TCP
The HTTPS protocol is often used in conjunction with SOAP to enable more secure exchanges. HTTPS (Hypertext Transfer Protocol Secure) provides a secure communication channel over the internet, ensuring the confidentiality and integrity of data exchanged between clients and services.
Which type of web service is more suitable for asynchronous processing and complex operations?
- JSON-RPC
- REST (Representational State Transfer)
- SOAP (Simple Object Access Protocol)
- XML-RPC
SOAP is more suitable for asynchronous processing and complex operations. It supports features like message queuing and transactions, making it a preferred choice for scenarios where robust communication and coordination are essential.
In token-based authentication, what is the main advantage of using tokens over traditional credentials?
- Compatibility with legacy systems
- Simplicity in implementation
- Stateless nature and scalability
- Strong encryption of credentials
Token-based authentication offers a stateless and scalable solution, as tokens carry the necessary information and reduce the need for server-side storage of session data.
In a scenario involving microservices architecture, why would JWT be preferred over traditional session-based authentication?
- Compatibility with legacy systems
- Simplicity and ease of implementation
- Stateless nature and scalability
- Tight coupling between services
JWT is preferred in microservices architectures due to its stateless nature, making it scalable and efficient. It eliminates the need for centralized session management.
A development team is testing a web application under various load conditions. Which approach should they use for best results?
- Acceptance Testing
- Regression Testing
- Stress Testing
- Unit Testing
Stress testing involves testing a system under extreme conditions, helping to identify its robustness and performance under heavy loads.
