When designing a web application with five web nodes to ensure availability, which method should be used?

• A. Load balancing
• B. Round Robin
• C. Straight-through routing
• D. Static IP configuration

Answer: (B)

The best method to ensure availability when designing a web application with multiple web nodes is load balancing. Load balancing distributes incoming network traffic across multiple servers, which helps ensure that no single server becomes overwhelmed by too much traffic. By balancing the load among the five web nodes, the application can maintain high availability and performance, even if one or more nodes experience downtime or high traffic. While round-robin is a load balancing technique that distributes requests in a rotating manner to each server, simply selecting it doesn't encompass the full range of strategies and technologies available for achieving high availability. Static IP configuration is more about defining fixed IP addresses for servers, rather than how to manage traffic effectively among them. Straight-through routing doesn't apply in this context because it refers more to routing and switching in networks, rather than load distribution for web applications. A comprehensive availability strategy should utilize load balancing as a core component, making it the preferred choice for maintaining application availability across multiple web nodes.
