Final answer:
The statement regarding only ESXi6 hosts being enabled for VM component protection is false. This feature is included in vSphere HA from version 6.0 onwards, not just ESXi6, and assists in automated recovery for VMs experiencing datastore accessibility issues.
Step-by-step explanation:
The statement that only ESXi6 host can be enabled for VM component protection, which allows vSphere HA to detect datastore accessibility failures and provides automated recovery for affected virtual machines, is False. VM component protection is a feature available in VMware vSphere High Availability (HA) starting with version 6.0, but it is not exclusive to ESXi6. It is also available in newer versions. This feature is important for maintaining the high availability of virtual machines by providing automated responses to datastore isolation incidents. When the VM component protection service detects that a datastore has become inaccessible, it can respond in several ways, such as restarting affected VMs on other hosts that have access to the datastore.
