In integration testing, which tool is used to simulate the behavior of web service components?
- Git
- JIRA
- Selenium
- SoapUI
SoapUI is a widely used tool for simulating the behavior of web service components in integration testing.
_______ is a technique in web services that dynamically allocates resources to handle varying loads.
- Dynamic resource allocation
- Load balancing
- Resource pooling
- Scalability
Dynamic resource allocation is a technique in web services that dynamically allocates resources to handle varying loads efficiently.
What best practice ensures web services are scalable and maintainable?
- Monolithic architecture
- RESTful architecture
- Spaghetti code
- Tight coupling
Adhering to RESTful architecture is a best practice for ensuring web services are scalable and maintainable, promoting loose coupling and scalability.
In RESTful services, what does the term 'Resource' fundamentally represent?
- Data object
- Database table
- Endpoint
- Web page
In RESTful services, a 'Resource' fundamentally represents an endpoint or a service that can be identified by a unique URI (Uniform Resource Identifier). Resources are entities that the API can act upon, and they can represent data objects, services, or entities that the API interacts with.
_______ framework is preferred for unit testing in Java-based web services.
- JUnit
- MSTest
- NUnit
- TestNG
JUnit is a popular framework for unit testing in Java-based web services.
In the context of web services, how does SSL/TLS encryption enhance security?
- Encrypts data during transmission
- Implements server load balancing
- Optimizes web service response time
- Provides secure database storage
SSL/TLS encryption ensures that data transmitted between clients and servers is encrypted, enhancing the security of the communication.
o improve the performance of a web service, developers often use _______ for data caching.
- In-Memory Storage
- NoSQL Database
- Redis
- SQL Database
Redis is commonly used for caching in web services to enhance performance by storing frequently accessed data in-memory.
In Microservices Architecture, what pattern is used to maintain data consistency across services?
- Factory Pattern
- Observer Pattern
- Saga Pattern
- Singleton Pattern
The Saga Pattern is commonly used in Microservices Architecture to manage distributed transactions and maintain data consistency across services.
When creating an API for a blog, which method should be used to ensure the client can discover the allowed HTTP methods for a resource?
- OPTIONS
- GET
- DISCOVER
- DESCRIBE
To enable clients to discover the allowed HTTP methods for a resource in an API, the OPTIONS method should be used. The server responds with information about the communication options for the target resource, allowing clients to determine which methods are supported.
In terms of security, which data format presents more challenges and why?
- JSON
- SOAP
- XML
- YAML
XML presents more security challenges compared to JSON. This is because XML documents can include various features, such as DTD (Document Type Definition) and external entity references, which might be exploited for attacks like XXE (XML External Entity) injections. JSON, being simpler, tends to have a more straightforward and secure parsing process.
