Network load balancing refers to balancing traffic across two or more WAN links. Which option best describes this concept?

• A. Increasing encryption
• B. Detecting intrusions
• C. Decreasing bandwidth
• D. Balancing traffic across two or more WAN links

Answer: (D)

Distributing traffic over multiple WAN connections is about using more than one path to move data, so no single link becomes a bottleneck and overall availability improves. When you have two or more Internet links, a load-balancing mechanism spreads different traffic flows across those links, sometimes using simple or dynamic rules to maximize throughput and provide continuity if one path fails. That directly matches the idea of balancing traffic across two or more WAN links. The other options describe encryption, intrusion monitoring, or simply reducing capacity, none of which address how traffic can be shared across multiple connections.
