Question
An attempt to enable vSphere Fault Tolerance for a powered-on virtual machine fails. Which two scenarios would result in this failure? (Choose two.)
Options
- AThe virtual machine has three vCPUs configured.
- BThe host on which the virtual machine is running has insufficient memory resources.
- CThe virtual machine has insufficient resources to accommodate full reservation plus the overhead
- DVMware High Availability is enabled on the cluster of which this host is a member.
Explanation
vSphere Fault Tolerance fails to enable when the host lacks sufficient memory to support the secondary VM or when the VM cannot accommodate the full memory reservation FT requires.
Common mistakes.
- A. Modern vSphere FT supports up to 8 vCPUs per VM, so a VM configured with 3 vCPUs is well within the supported limit and would not cause enablement to fail.
- D. VMware High Availability must actually be enabled on the cluster as a prerequisite for Fault Tolerance - having HA enabled is a requirement, not a cause of failure.
