Which load-balancing method would cause new connections to be directed to the server with the least network utilization?

• A. Least connection
• B. Least response time
• C. Least packets
• D. Least bandwidth

Answer: (D)

Directing new connections to the server with the least bandwidth usage targets how much data is actually moving through each link. By picking the one with the smallest current bandwidth consumption, you give new traffic to the server that has the most available network capacity, which helps balance overall throughput and prevents bottlenecks on busier servers. This metric reflects real-time network load, not just how many connections a server has or how quickly it responds. Other metrics don’t focus on ongoing data throughput: few active connections don’t guarantee low data flow, latency doesn’t measure how much bandwidth is being used, and the number of packets can be high or low regardless of how much data is being transferred. Thus, using the server with the least bandwidth usage best achieves balanced network utilization.
