Which vSphere feature provides continuous availability, allowing users to protect any virtual machine from a host failure with no loss of data or connectivity?
A. vSphere Fault Tolerance
vSphere Fault Tolerance (FT) is designed to provide continuous availability for a single virtual machine. It creates a secondary instance of the virtual machine on a different host, and if the primary host fails, the secondary instance takes over immediately with no downtime. This ensures that users experience uninterrupted service.
The vSphere feature that provides continuous availability and protects virtual machines from host failures with no loss of data or connectivity is vSphere High Availability (HA).
vSphere HA monitors the health of virtual machines and the hosts they are running on. If a host fails, vSphere HA restarts the virtual machines on other hosts within the same cluster, providing fast recovery from host failures.
So, the correct answer is "D" - vSphere HA.
vSphere Fault Tolerance (FT) is another feature that provides high availability for virtual machines, but it is different from vSphere HA. vSphere FT provides continuous availability by creating and maintaining a duplicate, or secondary, virtual machine that is identical to the primary virtual machine.
vSphere vMotion allows you to move a running virtual machine from one host to another with no downtime.
Enhanced vMotion Compatibility (EVC) enables vMotion between hosts with different CPU generations, as long as they have compatible virtualization features.
Please disregard the previous answer!
A. vSphere Fault Tolerance.
vSphere Fault Tolerance (FT) is a feature in VMware vSphere that provides continuous availability for virtual machines. It protects virtual machines from host failures by creating a live secondary copy of the virtual machine that runs on another host in the same cluster. In the event of a host failure, the secondary copy takes over and continues to run, ensuring that there is no loss of data or connectivity. vSphere FT provides a high level of data protection and allows users to continue working even if a host fails, making it an ideal solution for critical applications that require high availability.
A. is the correct answer because vSphere Fault Tolerance is the only feature that will provide continuous availability by keeping an identical copy of the running VM at all times.
