What is the primary function of a load balancer?

• A. To ensure data is sent securely over the internet
• B. To allow devices to connect to wireless networks
• C. To distribute network or application traffic across multiple servers
• D. To monitor network traffic for performance issues

Answer: (C)

The primary function of a load balancer is to distribute network or application traffic across multiple servers. This ensures that no single server becomes overwhelmed with too much traffic, which can lead to performance degradation or downtime. By evenly distributing the incoming traffic, load balancers enhance the availability and reliability of applications, allowing for better resource utilization and improved response times. This traffic distribution is crucial in environments where high availability is essential, such as in web applications or services that experience variable loads. In addition to balancing traffic, load balancers can offer features like health checks to ensure that only operational servers receive requests, further optimizing performance and reliability.
