What role does database optimization play in the performance of a web service?
- It enhances data security
- It has no impact on performance
- It improves response time and reduces resource usage
- It only affects the database, not the web service
Database optimization plays a crucial role in web service performance by improving response time and reducing resource usage through efficient data retrieval and storage strategies.
A financial service is integrating third-party payment services. What security standard should be prioritized for authentication and authorization?
- OAuth 2.0
- OpenID Connect
- PCI DSS (Payment Card Industry Data Security Standard)
- SAML (Security Assertion Markup Language)
PCI DSS is a security standard designed for securing payment transactions and protecting cardholder data. When integrating third-party payment services, prioritizing PCI DSS compliance ensures the secure handling of sensitive financial information and compliance with industry standards.
How do mock services assist in the process of integration testing?
- By automatically fixing integration issues
- By enforcing strict security protocols
- By generating random test data
- By simulating the behavior of external dependencies
Mock services assist in integration testing by simulating the behavior of external dependencies, enabling thorough testing without relying on actual external systems.
For monitoring Microservices, _______ is an essential practice.
- Code Obfuscation
- Distributed Tracing
- Static Analysis
- Uptime Monitoring
Distributed Tracing is essential for monitoring Microservices, allowing tracking and analysis of requests as they traverse through various services.
________ in UDDI is critical for defining the technical details of a web service.
- bindingTemplate
- serviceDetails
- tModel
- technicalDescriptor
In UDDI, the bindingTemplate is critical for defining the technical details of a web service. It specifies the technical aspects of a service, such as the access point and other relevant information necessary for service consumption.
_______ ensures the integrity and authenticity of XML messages in web services.
- XML Encryption
- XML Serialization
- XML Signature
- XML Validation
XML Signature is used to ensure the integrity and authenticity of XML messages in web services.
Which technology allows clients to query exactly what they need and nothing more?
- GraphQL
- REST
- SOAP
- XML-RPC
GraphQL allows clients to query and retrieve exactly the data they need, providing more flexibility compared to other technologies.
When designing a large-scale distributed system, how does SOAP affect system performance and interoperability?
- SOAP can introduce overhead due to XML processing
- SOAP has minimal impact on interoperability
- SOAP improves performance by reducing network latency
- SOAP is not suitable for large-scale systems
SOAP can introduce overhead due to XML processing, impacting system performance. However, it enhances interoperability by providing a standardized communication format.
In SOAP UI, the process of simulating a web service before its actual implementation is known as _______.
- Mocking
- Simulating
- Stubbing
- Testing
In SOAP UI, the process of simulating a web service before its actual implementation is known as "Mocking." This allows for testing without the actual service being available.
A company is implementing a web service and needs to ensure secure message exchange. Which approach should be prioritized?
- Employing API keys in the URL
- Encrypting data at the application layer
- Implementing HTTPS with SSL/TLS
- Using plain HTTP for simplicity
To ensure secure message exchange, HTTPS with SSL/TLS should be prioritized. This provides encryption and authentication, enhancing security.
