Which tool is commonly used for load testing of web services?
- Apache JMeter
- Docker
- Git
- Selenium
Apache JMeter is a popular tool used for load testing of web services, allowing testers to simulate various user loads and analyze system performance.
Which service in AWS provides scalable computing capacity?
- AWS EC2 (Elastic Compute Cloud)
- AWS Lambda
- AWS RDS (Relational Database Service)
- AWS S3 (Simple Storage Service)
AWS EC2 (Elastic Compute Cloud) provides scalable computing capacity by allowing users to run virtual servers in the cloud.
For a service requiring detailed and structured contracts, _______ would be a more appropriate choice over _______.
- GraphQL
- REST
- SOAP
- WebSocket
For a service requiring detailed and structured contracts, SOAP (Simple Object Access Protocol) would be a more appropriate choice over REST (Representational State Transfer). SOAP provides a formal contract through WSDL (Web Services Description Language), making it suitable for scenarios where a strict and defined interface is crucial. REST, on the other hand, is more flexible and often preferred for lightweight and loosely-coupled systems.
The _______ feature in Azure provides a serverless compute service.
- Azure App Service
- Azure Batch
- Azure Functions
- Azure Logic Apps
Azure Functions is a serverless compute service that allows you to run event-triggered code without explicitly provisioning or managing infrastructure.
SOAP services use _______ to define the structure of the request and response messages.
- HTML
- JSON
- XML
- YAML
In SOAP services, XML is used to define the structure of both the request and response messages. XML provides a standardized format for data exchange, making it suitable for describing the structure and content of messages in a consistent manner.
What is the primary security concern in OAuth 2.0 Implicit Grant compared to Authorization Code Grant?
- Access tokens are exposed in the URL
- Lack of token expiration mechanism
- Limited support for mobile applications
- User credentials are exchanged for tokens
The primary security concern in OAuth 2.0 Implicit Grant is that access tokens are exposed in the URL, which poses a potential security risk.
In the context of SOAP services, which aspect is crucial to test in a unit test?
- Database integrity
- Message structure and format
- Network latency
- User interface responsiveness
In SOAP services, it's crucial to test the message structure and format to ensure proper communication between components.
In RESTful services, _______ method is used for applying partial modifications to a resource.
- GET
- PATCH
- POST
- PUT
In RESTful services, the PATCH method is used for applying partial modifications to a resource. It is suitable for making specific updates to a resource without affecting the entire resource representation. This is particularly useful for scenarios where a complete update (PUT) is not necessary or efficient.
For an organization with diverse legacy systems, what SOA strategy should be applied for effective integration?
- Adhering strictly to a monolithic architecture
- Ignoring legacy systems during the integration
- Replacing all legacy systems with new ones
- Service-oriented Integration (SOI)
Service-oriented Integration (SOI) is the appropriate SOA strategy for an organization with diverse legacy systems. This approach focuses on integrating services seamlessly without requiring the immediate replacement of legacy systems, ensuring a gradual and effective transition to a service-oriented architecture.
What primary function does an API Gateway perform in a microservices architecture?
- Authentication and routing
- Data storage in microservices
- Service aggregation and composition
- User interface design
An API Gateway in a microservices architecture often handles authentication, routing, and acts as a single entry point for client requests.
