Question
An administrator has been tasked with deploying a new workload domain consisting of six VMware ESX hosts with VMware vSAN into an existing VMware Cloud Foundation (VCF) instance. After starting the deployment from VCF Operations, they discover that only four of the six hosts required are listed for selection in the UI. The administrator checks the Unassigned Host Inventory view in the vSphere Client and confirms that all six hosts are listed. Which step should the administrator perform to identify why the two hosts are not available for selection?
Options
- ACheck that the management port group on the standard switch has been enabled for vSAN traffic.
- BCheck that the failures to tolerate (FTT) setting for the workload domain is set to 0.
- CCheck that all disk partitions have been deleted from the SSD drives of the hosts.
- DCheck that the network pool the hosts have been associated with is enabled for vSAN.

Explanation
When deploying a new workload domain in VMware Cloud Foundation (VCF), only ESXi hosts that fully meet all pre-requisites are displayed in the VCF Operations UI for selection. Although all six hosts appear in the Unassigned Host Inventory in vCenter, VCF performs additional validation before making them selectable for workload domain deployment. One of the mandatory requirements for any vSAN-enabled workload domain is that the ESXi hosts must be associated with a Network Pool configured for vSAN traffic. A network pool defines the host network configuration (VLANs, MTU, NIC mapping) used during domain deployment. If the two missing hosts are associated with a network pool that does not have vSAN traffic enabled, or are associated with no network pool at all, VCF will exclude them from the workload domain deployment wizard. This is documented behavior: VCF filters out hosts when required network intents--such as vSAN--are not present.
