- Scalability
- Throughput
Latency measures the time delay between the initiation and execution of a request. Addressing latency is crucial in resolving intermittent slowdowns.
_______ is essential in a web service to ensure different versions of the service can coexist without disruption.
- Compression
- Encryption
- Scalability
- Versioning
Versioning is crucial in web services to allow different versions to coexist, ensuring backward compatibility and a smooth transition for clients.
When a financial service provider uses a web service, what key compliance factor should be evaluated?
- GDPR (General Data Protection Regulation)
- HIPAA (Health Insurance Portability and Accountability Act)
- PCI DSS (Payment Card Industry Data Security Standard)
- SOX (Sarbanes-Oxley Act)
Financial service providers using web services should prioritize compliance with PCI DSS to secure payment card data.
What is the significance of following a RESTful design pattern in web service development?
- High resource utilization
- Stateless communication
- Tight coupling between components
- XML-based communication

For a web service that needs to securely exchange sensitive data with a SOAP-based system, what security implementation is most suitable?
- JWT (JSON Web Tokens)
- OAuth 2.0
- SSL/TLS (Secure Socket Layer/Transport Layer Security)
- WS-Security
WS-Security is a standard for securing SOAP-based web services. It provides a comprehensive set of specifications for securing message integrity, confidentiality, and authentication. When dealing with sensitive data exchange in SOAP, WS-Security is a suitable choice for robust security.
