Which feature in VMware vSphere ensures zero downtime and prevents data loss when a physical server fails?
A . vSphere Data Protection
B . High Availability
C . Fault Tolerance
D . vSphere Replication
Answer: C
Explanation:
In the event of server failures, VMware vSphere Fault Tolerance (vSphere FT) provides continuous availability for applications with as many as four virtual CPUs. It does so by creating a live shadow instance of a VM that is always up to date with the primary VM. In the event of a hardware outage, vSphere FT automatically triggers failover, ensuring zero downtime and preventing data loss. Like vSphere HA, it protects against hardware failure but completely eliminates downtime with instantaneous cutover and recovery. After failover, vSphere FT automatically creates a new, secondary VM to deliver continuous protection for the application Reference: https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmwarevcenter-server-6-0-availability-guide-white-paper.pdf
