https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-70-availability-guide.pdfThe correct answer is D. 3.
vCenter High Availability (HA) is a feature in VMware vSphere that protects the vCenter Server against host and hardware failures by providing automatic failover to a secondary vCenter Server instance. In order to enable this feature, a minimum of three ESXi hosts is required.
The three hosts are used to create a vSphere HA cluster, with one host designated as the primary node and the other two hosts acting as standby nodes. The primary node hosts the active vCenter Server instance, while the standby nodes are kept in sync with the primary node and are ready to take over in the event of a failure.
If any of the hosts fail, the remaining hosts in the vSphere HA cluster will continue to operate, and the standby node with the most up-to-date copy of the vCenter Server database will be automatically promoted to the primary node.
In summary, the minimum number of ESXi hosts required to enable vCenter High Availability is three.
