Why might an organization choose to implement vSphere Fault Tolerance?

Implementing vSphere Fault Tolerance is primarily aimed at achieving zero downtime for mission-critical applications. This feature allows virtual machines to continue running uninterrupted in the event of hardware or software failures, by creating a live shadow instance of a VM that runs in lockstep with the primary VM. Therefore, if the primary VM encounters a failure, the secondary instance can take over immediately without any interruption to service, ensuring that critical applications are always available. This capability is essential for organizations that cannot afford any downtime, as it helps maintain business continuity and reliability.

The other options, while important in the context of virtual infrastructure management, do not directly relate to the core purpose of Fault Tolerance. For example, enhancing storage capacity and simplifying VM cloning pertain to different aspects of virtualization management that do not address availability during faults. Similarly, improved VM migration speed is more about efficiency in resource allocation rather than ensuring continuous operation during failures. Hence, the choice emphasizing zero downtime aligns perfectly with the fundamental goal of implementing vSphere Fault Tolerance.
