In terms of API versioning, how does GraphQL differ from REST?
- GraphQL typically doesn't require versioning
- GraphQL uses URL versioning
- REST automatically handles version updates
- REST uses HTTP headers for versioning
GraphQL typically doesn't require versioning due to its flexible schema and ability to request only the needed data.
How does WSDL facilitate the interaction between different web services?
- By enabling user interface creation
- By executing server-side scripts
- By managing database connections
- By providing a standard way to describe the interface and communication protocols
WSDL (Web Services Description Language) facilitates interaction by providing a standardized way to describe the interface and communication protocols of web services. This allows for interoperability between different systems.
In debugging complex scenarios, _______ allows simulation of various service responses.
- Authorization
- Compression
- Encryption
- Mocking
Mocking allows developers to simulate various service responses, aiding in debugging complex scenarios.
In SOAP, _______ is used to encode complex data types.
- JSON
- SOAP Encoding
- WSDL
- XML Schema
SOAP Encoding is a method used in SOAP to encode complex data types in a way that can be transmitted over the network, facilitating interoperability.
The approach where tests are written before the actual web service code is known as _______.
- Agile Development
- Behavior-Driven Development (BDD)
- Test-Driven Development (TDD)
- Waterfall Development
Test-Driven Development (TDD) is an approach where tests are written before writing the actual code, promoting a more testable and reliable codebase.
What metric in performance testing measures the number of requests a service can handle per second?
- Concurrent Users
- Latency
- Response Time
- Throughput
Throughput in performance testing measures the number of requests a service can handle per second, providing insight into system capacity.
When a web service experiences intermittent slowdowns, what aspect should be the focus of performance testing?
- Latency
- Reliability
- 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.
How does an API Gateway enhance the functionality of web services?
- Centralized management of API requests
- Database management for web services
- Graphic design for APIs
- Load balancing for web servers
An API Gateway enhances web service functionality by providing centralized management of API requests, including routing, security, and load balancing.
