A team is deploying a stateful application that requires clients to consistently connect to the same backend server. They also want to distribute load evenly. Which load balancing configuration should they use?

Round-robin with session persistence

IP hash without session persistence

Least connections without session persistence

Random with session persistence

A company has multiple back-end services that need to be accessed by both internal and external clients. They want to enforce different security policies for each group. They also want to simplify client integration by providing a single endpoint. Which solution is most appropriate?

Deploy two API gateways: one for internal traffic and one for external traffic

Use a single API gateway with the same policies for all clients

Expose each service directly with its own security

Use a reverse proxy for external traffic and direct access for internal traffic

An e-commerce application stores the user's shopping cart in a server-side session. The application is deployed behind a load balancer with multiple backend servers. What must be configured to ensure a user's cart is not lost when subsequent requests are sent to different servers?

Health checks on the backend servers

Session persistence (sticky sessions) on the load balancer

Round-robin load balancing algorithm

A company has a microservices architecture where each service exposes its own API. They want to provide a single, unified API to external clients and also handle authentication and rate limiting. Which solution best meets these needs?

Expose each microservice directly to the internet

Implement authentication in each microservice independently

Deploy an API gateway that routes requests to the appropriate microservices

Use a load balancer in front of each microservice
