What distinguishes Microservices Architecture from traditional SOA?
- Centralized data storage
- Granular and independent services
- Monolithic and tightly coupled services
- Standardized communication protocols
Microservices Architecture is characterized by granular and independent services, each responsible for a specific business capability. This contrasts with traditional SOA, which often involves monolithic and tightly coupled services.
How can a web service ensure secure transmission of XML data over the internet?
- Hypertext Transfer Protocol (HTTP)
- JavaScript Object Notation (JSON)
- Representational State Transfer (REST)
- Transport Layer Security (TLS)
Transport Layer Security (TLS) ensures secure transmission by encrypting data during communication over the internet.
In Azure, what is the primary service used for relational database management?
- Azure Blob Storage
- Azure Cosmos DB
- Azure SQL Database
- Azure Table Storage
Azure SQL Database is the primary service in Azure used for relational database management.
In Postman, how are environment variables used during API testing?
- Defining API specifications
- Executing load tests
- Generating test reports
- Storing and managing dynamic values
In Postman, environment variables are used for storing and managing dynamic values, providing flexibility in API testing scenarios.
In a scenario where a web service needs to manage sensitive user data, what authentication technique is most appropriate?
- Biometric Authentication
- Client Certificates
- OAuth 2.0
- Two-Factor Authentication
Client Certificates provide an extra layer of security, making them suitable for scenarios where sensitive user data is involved.
What is the main advantage of using a bottom-up approach in integration testing?
- Early identification of defects at the lower levels
- Easier to manage and control
- Faster execution of test cases
- Higher test coverage
The main advantage of the bottom-up approach in integration testing is the early identification of defects at the lower levels of the application architecture.
What role does an API Gateway play in service discovery in a microservices architecture?
- It acts as a mediator, directing requests to the appropriate microservices
- It has no role in service discovery in microservices
- It hosts the microservices and manages their communication
- It only provides documentation for microservices
An API Gateway in a microservices architecture plays a role in service discovery by acting as a mediator, directing requests to the relevant microservices based on the request's destination.
In a federated security model, what role does an Identity Provider (IdP) play?
- It controls access to physical resources
- It encrypts data during transit
- It manages user identities and authenticates users
- It secures the network infrastructure
In a federated security model, an Identity Provider (IdP) manages user identities and authenticates users across multiple systems.
