Five Windows Server 2016 VMs host websites behind an Azure load balancer named LB1. To make sure each visitor is always directed to the same web server, which setting should you apply?

Setting session persistence to Client IP ensures that all subsequent requests from the same client IP address are directed to the same backend instance. This is crucial for maintaining session state in web applications where a user's session data might be stored on a specific server. Setting Floating IP (direct server return) to Enabled or Disabled affects how the load balancer handles responses, but not how client requests are distributed to specific backend servers for session continuity. A health probe monitors the availability of backend instances but does not influence session stickiness.
