- Transformers
Transformers in API Gateways can transform incoming requests before routing them to appropriate services.
Which HTTP method does SOAP typically use for sending requests?
- DELETE
- GET
- POST
- PUT
SOAP typically uses the HTTP POST method for sending requests. This allows the transmission of data to a specific resource on the server to create or update a resource.
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.
The _______ header in HTTP responses can provide additional information about errors.
- "Error"
- "Exception"

- "Status"
The "Status" header in HTTP responses can provide additional information about errors.
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.
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 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.
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.
