Which tool is commonly used for creating mock RESTful services?
- Postman
- SoapUI
- Swagger
- WireMock
WireMock is commonly used for creating mock RESTful services, allowing developers to simulate responses for testing purposes.
What distinguishes SOAP 1.1 from SOAP 1.2 in terms of error handling?
- SOAP 1.2 does not support error handling
- SOAP 1.2 introduces the Fault element
- SOAP 1.2 relies on external error files
- SOAP 1.2 uses a different error code system
SOAP 1.2 introduces the Fault element, which is used to carry error information. Unlike SOAP 1.1, where error details were part of the body, SOAP 1.2 separates error information into the Fault element, providing a standardized way to convey fault-related information in a consistent and extensible manner.
Which protocol is essential for achieving interoperability in web services?
- FTP
- JSON
- REST
- SOAP
SOAP (Simple Object Access Protocol) is essential for achieving interoperability in web services. It provides a standardized way for communication, allowing applications to exchange structured information over a network, promoting compatibility among systems with different technologies.
In Microservices Architecture, the strategy to deal with failure in one service is known as _______.
- Circuit Breaker
- Load Balancer
- Middleware
- Proxy
The strategy to deal with failure in one service in Microservices Architecture is known as the Circuit Breaker pattern, which helps prevent cascading failures.
_______ tools help in monitoring the real-time performance and requests in web services.
- Debugging
- Monitoring
- Profiling
- Tracing
Monitoring tools are essential for real-time performance and request tracking in web services.
Which design principle in SOA emphasizes the use of standardized service contracts?
- Service Abstraction
- Service Loose Coupling
- Service Reusability
- Service Standardization
In SOA, the design principle that emphasizes the use of standardized service contracts is Service Standardization. Standardized contracts define the way services interact, promoting consistency and interoperability. This principle facilitates a more uniform and predictable integration between services, contributing to the overall success of the SOA implementation.
What strategy can be used to handle deprecated features in web service versioning?
- Force clients to upgrade immediately
- Maintain backward compatibility
- Remove deprecated features abruptly
- Use version headers for each request
To handle deprecated features in web service versioning, maintaining backward compatibility is a common strategy. This allows existing clients to continue functioning while encouraging them to update gradually.
_______ is a tool in Docker for defining and running multi-container Docker applications.
- Docker Compose
- Docker Hub
- Docker Registry
- Docker Swarm
Docker Compose is a tool in Docker for defining and running multi-container Docker applications. It allows you to manage and orchestrate multiple containers as a single service.
How does a stress test differ from a load test in the context of web services?
- Load testing is not applicable to web services.
- Stress testing assesses system behavior under expected conditions, while load testing simulates extreme conditions to identify failure points.
- Stress testing focuses on normal usage conditions, while load testing simulates extreme conditions to identify failure points.
- Stress testing simulates extreme conditions beyond normal usage, focusing on system failure points. Load testing assesses system behavior under expected conditions, testing scalability.
Stress testing and load testing serve distinct purposes. Stress testing aims to evaluate system behavior under extreme conditions, while load testing assesses performance under expected conditions.
In REST, how are different resources typically accessed?
- Through HTML (Hypertext Markup Language)
- Through SOAP (Simple Object Access Protocol)
- Through TCP (Transmission Control Protocol)
- Through URIs (Uniform Resource Identifiers)
RESTful resources are typically accessed through URIs, providing a standardized way to identify and interact with resources.
