In the context of web services, serverless computing primarily means what?
- Direct server control for applications
- Graphic design for server architecture
- Load balancing for web servers
- Running applications without managing server infrastructure
Serverless computing in web services means running applications without managing server infrastructure, allowing developers to focus on code rather than server management.
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.
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.
A web service needs to exchange data with multiple clients using XML. What is the best approach to ensure data consistency and validation?
- Document Object Model (DOM)
- Representational State Transfer (REST)
- Simple Object Access Protocol (SOAP)
- XML Schema Definition (XSD)
XML Schema Definition (XSD) is used to define the structure and data types of XML, ensuring consistency and validation in data exchange.
