What is the significant difference between SAML and OAuth in authentication processes?
- OAuth focuses on user authentication, while SAML focuses on data encryption
- OAuth is a markup language, while SAML is a protocol
- SAML is primarily used for single sign-on (SSO), while OAuth is an authorization framework for granting access
- SAML is used exclusively in mobile applications, while OAuth is used in web applications
SAML is commonly used for single sign-on (SSO), providing a way to authenticate users across multiple applications. OAuth, on the other hand, is primarily an authorization framework for granting access to resources.
_______ testing assesses the web service's ability to handle sudden spikes in traffic.
- Load
- Performance
- Scalability
- Stress
Stress testing assesses a web service's ability to handle sudden spikes or high levels of traffic.
In a complex SOAP service, how is the communication sequence between operations defined?
- Asynchronously through callback mechanism
- Synchronously through request-response
- Through parallel execution
- Through publish-subscribe model
In SOAP, communication between operations can be defined synchronously through the traditional request-response mechanism. This ensures a sequential flow of operations, where each operation depends on the completion of the previous one.
A developer is designing an API endpoint for updating user profiles where partial update is expected. Which HTTP method should be used?
- PATCH
- POST
- PUT
- UPDATE
When a partial update is expected in an API endpoint, the appropriate HTTP method to use is PATCH. PATCH is designed to apply partial modifications to a resource, making it suitable for updating specific fields in a user profile without affecting the entire resource.
What feature of API Gateways helps in managing the load on backend services?
- Load balancing
- Load lifting
- Load shedding
- Load stacking
API Gateways use load balancing to distribute client requests evenly across backend services, preventing overloading of any single service.
In a Microservices Architecture, when a new service is added, what factor is most critical for system stability?
- Code optimization for speed
- Front-end framework selection
- Server hardware specifications
- Service dependencies and communication protocols
The most critical factor for system stability when adding a new service in a Microservices Architecture is understanding and managing service dependencies and communication protocols. Proper communication ensures the seamless integration of new services.
A company is transitioning to a microservices architecture. For optimal management and orchestration of their containers, which platform would be most suitable?
- Amazon S3
- Apache Kafka
- Docker
- Kubernetes
Kubernetes is a powerful platform for managing and orchestrating containers in a microservices architecture, providing features like service discovery, scaling, and load balancing.
In a situation where a mobile app needs to minimize data usage and improve load times, which API query language is more suitable?
- GraphQL
- OData
- REST
- SQL
REST is more suitable for scenarios where data usage needs to be minimized, as it follows a stateless architecture and allows clients to request only necessary data.
The _______ header in HTTP responses can provide additional information about errors.
- "Error"
- "Exception"
- "Message"
- "Status"
The "Status" header in HTTP responses can provide additional information about errors.
For effective monitoring and debugging, implementing _______ in web services is recommended.
- Authentication
- Exception Handling
- Logging
- Profiling
Logging is crucial for effective monitoring and debugging in web services, providing insights into the system's behavior.
