How does Microservices Architecture differ from a monolithic architecture in handling business functionalities?
- Independent deployability of services
- Limited scalability
- Single codebase for all services
- Tight coupling of services
Microservices Architecture allows for independent deployability of services, enabling flexibility and scalability in handling business functionalities.
GraphQL queries can reduce over-fetching issues, common in _______ based APIs.
- HTTP
- REST
- RPC
- SOAP
GraphQL queries are efficient in reducing over-fetching issues commonly associated with REST-based APIs.
In a scenario where an external API is unavailable for testing, what is the most effective alternative?
- Delaying testing until API is available
- Mocking the API responses
- Skipping API testing
- Using live production API
Mocking the API responses allows testing to proceed even when the actual API is unavailable, simulating its behavior for testing purposes.
In web services, a TLS handshake is used for what purpose?
- Checking the server's availability
- Establishing a secure connection between client and server
- Sending encrypted data
- Terminating the connection after data transmission
The TLS handshake is used to establish a secure connection between the client and the server, ensuring encrypted communication.
A web service is experiencing increased load and slowing down. What debugging strategy is most appropriate to identify bottlenecks?
- Code review
- Performance profiling
- Security testing
- Unit testing
Performance profiling is an appropriate debugging strategy to identify bottlenecks in a web service experiencing increased load and slowing down. It helps analyze the performance of different components.
Which type of testing is facilitated by the mocking service in SOAP UI?
- Load testing for APIs
- Security testing for APIs
- Simulating the behavior of a web service
- Unit testing for API components
The mocking service in SOAP UI facilitates simulating the behavior of a web service, allowing for testing interactions without invoking the actual service.
Which approach uses multiple endpoints for different resources?
- GraphQL services
- JSON-RPC services
- RESTful services
- SOAP services
RESTful services commonly use multiple endpoints for different resources, providing a clear and resource-centric structure.
_______ versioning involves maintaining multiple versions of the service at the same time.
- Concurrent
- Horizontal
- Parallel
- Vertical
Concurrent versioning involves maintaining multiple versions of the service at the same time.
The _______ algorithm in TLS is used for key agreement and establishment.
- AES
- HMAC
- RSA
- SHA-256
The RSA algorithm in TLS is utilized for key agreement and establishment during the handshake process.
A financial service is transmitting sensitive data over the web. Which encryption technique should be prioritized for data protection?
- AES
- Blowfish
- RSA
- Triple DES
In the context of transmitting sensitive data, Advanced Encryption Standard (AES) is commonly prioritized for its robust security.
How does JWT differ from session-based authentication in terms of scalability?
- JWTs and session-based authentication have similar scalability
- JWTs are stateless and don't require server-side storage
- JWTs require frequent server-side storage updates
- Session-based authentication is more scalable
JWTs (JSON Web Tokens) are stateless, meaning they don't require server-side storage, making them more scalable than session-based authentication, which relies on server-side storage.
The use of _______ ensures that web services can be accessed regardless of programming language or platform.
- CORBA (Common Object Request Broker Architecture)
- HTTP (Hypertext Transfer Protocol)
- URI (Uniform Resource Identifier)
- WSDL (Web Services Description Language)
The use of URI (Uniform Resource Identifier) ensures that web services can be accessed regardless of programming language or platform. URIs provide a standardized way to identify and locate resources on the web, promoting a language-agnostic and platform-independent approach.
