In a distributed web application, which responsibility is typically associated with the front-end component?

Rendering the user interface and handling user interactions in the browser

Authenticating users and issuing session tokens

Managing database connections and executing SQL queries

Enforcing business rules and processing business logic

A company runs a mix of stateless and stateful services behind a single load balancer. The stateless services handle short HTTP requests, while the stateful services require session persistence. The team wants to use a single load balancer to minimize infrastructure. Which configuration is most appropriate?

Configure separate listener pools with different algorithms and session persistence settings

Use least connections for all services and disable session persistence

Use round-robin for all services and enable session persistence globally

A development team is building a web application where the front-end is a single-page application (SPA) that communicates with a back-end API. They want to enforce security policies such as CORS and request validation before requests reach the back-end. Where should these policies be implemented?

In the API gateway or reverse proxy

In the back-end application code

In the front-end JavaScript code

How does a load balancer contribute to high availability in a distributed application?

By preventing any server from ever becoming unavailable

By redirecting traffic away from failed backend servers to healthy ones

By increasing the processing power of individual backend servers

By storing redundant copies of the application code on each server
