Performance testing should also evaluate the web service's _______ under different network conditions.
- Data Encryption
- Fault Tolerance
- Response Time
- Throughput
Throughput measures the amount of data transferred successfully over the network and is crucial for evaluating performance under various network conditions.
In REST, to update an existing resource partially, the _______ HTTP method is used.
- DELETE
- PATCH
- POST
- PUT
In REST, the PATCH HTTP method is used to update an existing resource partially. It allows clients to send only the changes to the resource, minimizing data transfer and improving efficiency when updating specific fields of a resource.
In microservices architecture, why is it essential to have independent deployment for each service?
- Enables updating and scaling of individual services without affecting others
- Facilitates centralized management of all services
- Reduces the need for inter-service communication
- Simplifies the testing process
Independent deployment in microservices architecture allows updating and scaling of individual services without affecting others, providing flexibility and autonomy for each service.
_______ 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.
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.
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.
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 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.
When designing a RESTful API for a global audience, what aspect is crucial for ensuring high availability and fault tolerance?
- Implementing a Content Delivery Network (CDN)
- Relying on client-side caching
- Using a single centralized server
- Utilizing geographically distributed servers
To ensure high availability and fault tolerance for a global audience, it's crucial to utilize geographically distributed servers, reducing latency and improving resilience.
A developer is integrating a legacy system with a modern application using SOAP. What should be considered for compatibility?
- Compatibility with RESTful APIs
- Compatibility with programming languages
- Hardware compatibility
- Version compatibility of SOAP
When integrating a legacy system with a modern application using SOAP, version compatibility of SOAP is crucial to ensure proper communication and data exchange.
Which international standard is commonly referenced for information security management?
- ISO 14001
- ISO 20000
- ISO 9001
- ISO/IEC 27001
ISO/IEC 27001 is the international standard commonly referenced for information security management.
How should a business assess the performance and ROI of its SOA implementation?
- Assess only the initial development costs
- Ignore performance metrics and focus on ROI
- Monitor service usage and response times
- Rely solely on user feedback for evaluation
Businesses should assess the performance and ROI of their SOA implementation by monitoring service usage and response times. This involves analyzing key performance metrics to ensure that the implemented services meet expectations and deliver the desired return on investment.
