What is a key characteristic of a stateless application?

It requires session persistence to maintain user data across requests

Each request is independent and contains all information needed to process it

It stores user session data on the server between requests

It can only run on a single server instance

In which scenario is the 'least connections' load balancing algorithm most appropriate?

When the application requires session persistence based on client IP

When all backend servers are identical in capacity and handle requests quickly

When the application has a single backend server

When backend servers have varying processing capacities and request durations

A company is deploying a critical application that must be highly available. They have two data centers, each with a set of backend servers. They want to distribute traffic across both data centers and also within each data center. Which load balancing strategy is most appropriate?

Use only local load balancers in each data center

DNS round-robin for cross-data-center and no local load balancing

Global load balancer (GSLB) for cross-data-center traffic and local load balancers within each data center

Single load balancer that routes to all servers in both data centers

Why does a stateful application require session persistence when deployed behind a load balancer?

To reduce the number of backend servers required for the application

To encrypt session data in transit between client and server

To distribute requests evenly across all backend servers

To ensure all requests from a client are sent to the same backend server that holds their session data
