Which of the following TSM commands is associated with configuring a load balancer?

The choice concerning configuring a load balancer is related to specifying the public hostname that will be utilized for external access to Tableau Server. By setting the gateway.public.host with the appropriate name, you ensure that the load balancer can direct requests to the correct server instance. This step is crucial in a load-balanced environment, ensuring that traffic is routed properly and that users can access Tableau Server through an appropriately configured entry point.

When a load balancer is deployed to distribute incoming traffic across several server nodes, configuring the public host name ensures that clients connect consistently and effectively to the right instance of Tableau Server. This is particularly important for maintaining session continuity and ensuring load distribution.

The other options, while they involve configuration settings related to the gateway, do not specifically address the need to assign a public host for the load balancer to operate effectively. The commands either pertain to trusted IP configurations, port settings, or securing the gateway, which are also important but do not directly influence the proper function of a load balancer in the context of external access to Tableau Server.
