Which load-balancing method is the simplest and does not consider current load or connections?

• A. Least Connections
• B. Least Bandwidth
• C. Round-robin
• D. Custom load

Answer: (C)

Round-robin is the simplest way to distribute work because it doesn’t look at how loaded each server is or how many connections it has. It just forwards each new request to the next server in a fixed order, cycling through the pool without any load data. This makes it easy to configure and operate since there’s no monitoring or metrics involved. It works best when all servers are similar and can handle similar workloads; if servers differ or traffic varies, some servers may become unevenly loaded. Other methods rely on current load or throughput: least connections picks the server with the fewest active connections, least bandwidth considers the amount of data each server is handling, and a custom load option uses user-defined metrics.
