An administrator has been tasked with deploying a new workload domain consisting of six VMware...

When deploying a new workload domain in VMware Cloud Foundation (VCF), only ESXi hosts that fully meetall pre-requisitesare displayed in the VCF Operations UI for selection. Although all six hosts appear in theUnassigned Host Inventoryin 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 aNetwork 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 thatdoes not have vSAN traffic enabled, or are associated withno network pool at all, VCF willexcludethem from the workload domain deployment wizard. This is documented behavior: VCF filters out hosts when required network intents—such as vSAN—are not present.

Other options are incorrect:

A. Management port group enabled for vSAN traffic— vSAN shouldneverrun on the management PG.

B. FTT setting— Has no effect on host visibility; applies only after deployment.

C. Disk partitions— Affects vSAN disk claim but doesnotprevent host selection in VCF.
