Which tool is commonly used for debugging RESTful services?
- Notepad
- Postman
- SoapUI
- Wireshark
Postman is commonly used for debugging RESTful services, allowing developers to send requests and inspect responses.
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.
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.
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.
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.
In SOA, services communicate with each other using which mechanism?
- File Transfer
- Messaging
- Remote Procedure Calls (RPC)
- Shared Databases
In Service-Oriented Architecture (SOA), services communicate with each other using the messaging mechanism. Messaging involves the exchange of information between services through messages, promoting a loosely coupled and asynchronous communication model. This mechanism enhances flexibility and scalability in the SOA environment.
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.
