REST APIs commonly use which method to retrieve data without affecting the resource?
- DELETE
- GET
- POST
- PUT
REST APIs commonly use the GET method to retrieve data without affecting the resource, emphasizing the idempotent nature of the operation.
In complex web services, how does WSDL handle multiple service endpoints?
- WSDL allows the definition of multiple service endpoints in the same document
- WSDL can't handle multiple endpoints in complex web services
- WSDL supports multiple endpoints by creating separate documents for each
- WSDL uses a single default endpoint for all services
WSDL allows the definition of multiple service endpoints in the same document, providing flexibility in handling complex web services.
How does a stub differ from a mock in integration testing?
- A mock is a complete, functional implementation of a component
- A mock is only used in object-oriented programming
- A stub is a simplified implementation of a component with fixed behavior
- A stub is used for unit testing, while a mock is used for integration testing
In integration testing, a stub is a simplified version of a component with predetermined behavior, while a mock is a complete, functional implementation with expected behavior.
_______ is a constraint of RESTful services that dictates the simplicity of the interface provided to services.
- HATEOAS
- Idempotence
- Statelessness
- Uniform Interface
In REST, the Uniform Interface constraint emphasizes a simple and consistent interface for services, promoting ease of use and understanding.
For deleting a resource in REST, what HTTP method is implemented?
- DELETE
- PATCH
- POST
- PUT
The DELETE method in REST is used to delete a resource. It requests the removal of the specified resource, and the operation is idempotent, meaning that subsequent requests have no additional effect once the resource is deleted.
What is the role of a 'Pod' in Kubernetes?
- A collection of multiple containers sharing the same network namespace
- A configuration file defining Kubernetes deployment settings
- A high-level Kubernetes resource for managing persistent data storage
- The smallest unit in the Kubernetes object model, representing a single instance of a running process
In Kubernetes, a Pod is the smallest unit, representing a single instance of a running process and can contain one or more containers.
_________ encryption uses the same key for encryption and decryption.
- Asymmetric
- Private
- Public
- Symmetric
Symmetric encryption utilizes the same key for both the encryption and decryption processes.
How does SOAP handle security compared to REST?
- REST relies on digital signatures for secure communication
- REST uses HTTPS for secure communication
- SOAP employs WS-Security for secure communication
- SOAP relies on API keys for security
SOAP, in comparison to REST, handles security through standards like WS-Security. This includes features such as encryption, digital signatures, and authentication mechanisms, providing a comprehensive approach to secure communication between web services.
In complex web service architectures, XML _______ is used for defining the message exchange patterns.
- Blueprint
- Protocol
- Schema
- Specification
In complex web service architectures, XML Schema is used for defining the message exchange patterns.
In microservices architecture, _______ patterns help in managing errors across service boundaries.
- Circuit Breaker
- Observer
- Proxy
- Singleton
In microservices architecture, Circuit Breaker patterns are employed to manage errors across service boundaries by preventing cascading failures.
