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.
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.
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.
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.
In JWT, what is the purpose of the 'signature' part?
- To compress the token payload
- To ensure the confidentiality of the token
- To provide a unique identifier for the token
- To verify the authenticity of the token
