A retailer wants to distribute incoming traffic across multiple Azure web servers to improve performance during peak times. Which service should they use?

Azure Load Balancer is the correct choice because it operates at Layer 4 (transport layer) and distributes incoming network traffic across multiple healthy virtual machines or instances within the same Azure region. This is ideal for improving performance and availability for web servers, especially during peak times. Azure Traffic Manager is a DNS-based traffic load balancer that distributes traffic globally, not within a region. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications, operating at Layer 7. Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications, also operating at Layer 7, offering features like SSL offloading and web application firewall, which are more advanced than simple traffic distribution.
