Which version of vSphere supports multi-vCPU VMs with Fault Tolerance?

The correct answer highlights that vSphere 6.0 was the version that introduced support for multi-vCPU virtual machines (VMs) with Fault Tolerance. Prior to this version, Fault Tolerance was limited to single vCPU VMs, making it less flexible for certain applications that require more processing power.

With the release of vSphere 6.0, VMware made significant enhancements to the Fault Tolerance feature, allowing not just single-vCPU but also multi-vCPU VMs to benefit from this high-availability feature. This advancement means that users could protect multi-threaded applications and workloads without having to modify their VM configurations to conform to the single-vCPU restriction.

Subsequent versions, like vSphere 6.5 and vSphere 7.0, continued to enhance overall features and performance but did not introduce the multi-vCPU capability for Fault Tolerance, which was already established in vSphere 6.0. Options prior to vSphere 6.0, such as 5.5, also did not support this feature, further reinforcing the significance of version 6.0 in this context.
