What role does SNI (Server Name Indication) play in TLS for web services?
- Allows a client to indicate the hostname it is attempting to connect to during the TLS handshake process
- Enables secure key exchange between client and server
- Facilitates secure data transmission between servers
- Provides encryption for server certificates
SNI allows a client to indicate the hostname during the TLS handshake, allowing servers to present the appropriate certificate for the requested domain.
How does UDDI support the concept of SOA (Service-Oriented Architecture)?

When a partial update is expected in an API endpoint, the appropriate HTTP method to use is PATCH. PATCH is designed to apply partial modifications to a resource, making it suitable for updating specific fields in a user profile without affecting the entire resource.
What feature of API Gateways helps in managing the load on backend services?
- Load balancing
- Load lifting
- Load shedding
- Load stacking
API Gateways use load balancing to distribute client requests evenly across backend services, preventing overloading of any single service.
In a Microservices Architecture, when a new service is added, what factor is most critical for system stability?
- Code optimization for speed
- Front-end framework selection
- Server hardware specifications
- Service dependencies and communication protocols
The most critical factor for system stability when adding a new service in a Microservices Architecture is understanding and managing service dependencies and communication protocols. Proper communication ensures the seamless integration of new services.
A company is transitioning to a microservices architecture. For optimal management and orchestration of their containers, which platform would be most suitable?
- Amazon S3

In a situation where a mobile app needs to minimize data usage and improve load times, which API query language is more suitable?
- GraphQL
- OData
- REST
- SQL
REST is more suitable for scenarios where data usage needs to be minimized, as it follows a stateless architecture and allows clients to request only necessary data.
