In the context of distributing connections across multiple broker VMs (such as Citrix Delivery Controllers or Horizon Connection Servers) without introducing complex third-party infrastructure dependencies like strict SDN overlays (Option A), Round-robin DNS is the standard supported method for connection distribution mentioned in basic Nutanix EUC architecture guides.

While enterprise production environments often use dedicated External Load Balancers (like Citrix ADC), Option A implies the mandatory use of Flow Virtual Networking (an overlay SDN solution) to achieve this, which is not a standard requirement for simple broker load balancing. Therefore, among the available choices, creating multiple DNS A-records for the broker FQDN (Round-robin DNS) is the valid mechanism to distribute incoming user traffic across the available broker nodes.
