What is the effect of selecting the 'Least bandwidth' load-balancing method?

• A. They route to the server with the most available bandwidth.
• B. They distribute load based on CPU usage.
• C. They route to the server with the least network utilization.
• D. They use random selection.

Answer: (C)

This question tests how the Least bandwidth load-balancing method works. When you choose Least bandwidth, traffic is directed to the server that is currently using the smallest amount of network bandwidth—that is, the server with the lightest current network load. The idea is to spread new requests across servers so the overall network utilization stays balanced and not congested on any single path. It’s about real-time network usage, not CPU power or random choice. It doesn’t pick the one with the most available bandwidth, and it isn’t choosing servers randomly; it specifically targets the lowest current network utilization.
