Question 81

What is the minimum number of ESXi hosts required to support vCenter High Availability?

Correct Answer: B

For vCenter High Availability, a minimum of three ESXi hosts is required. This setup includes an active node, a passive node, and a witness node, which should ideally be run on three separate hosts to ensure redundancy and high availability.

GodMan114Option: B

I thought the answer was "3" also, but found this here showing that "A cluster must contain at least two hosts." https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-BA85FEC4-A37C-45BA-938D-37B309010D93.html

vSphere HA needs a minimum of 2 hosts. vCenter HA is not the same thing. vCenter HA has three VMs (active, passive, and witness) that SHOULD run on three different hosts but don't technically HAVE to. This is a BS question.

2 = "Minimum 2 ESX hosts are required for setting up HA. However, to ensure redundancy and maximum Fault Tolerance protection, you should have a minimum of three hosts in the cluster." https://docs.vmware.com/en/VMware-Smart-Assurance/10.1.0/sa-ui-platform-user-config-guide-101/GUID-FCB6D75D-4CFD-4406-88E5-2DE160EBFA3C.html
