A municipal operations portal fans request traffic across several identical back-end workers that talk to Cisco controllers. What is the primary job of the load balancer in that design?
Select an answer to reveal the explanation.
Short Explanation
Picture a ticket window with several clerks behind it. The load balancer is the line manager who hands the next citizen to any free clerk—not the filing cabinet, the ID badge printer, or the backup vault. Its job is fan-out and hiding instance identity.
Full Explanation
In a distributed Cisco-API app, a load balancer spreads work across interchangeable back-end instances so no single process is the only listener. It is not an HTTP cache, an OAuth authorization server, or the database failover node. Those roles belong to other components. Treat the balancer as the fan-out edge that masks which healthy worker answered.
