John, a VMware administrator, has set a virtual machine as fault tolerant using VMware Fault Tolerance. The fault-tolerant pair of virtual machines worked as expected for several weeks, but for the past two days the fault tolerant pair has been failing over repeatedly. Though there hasn't been an outage, John is concerned. What is a likely cause of the repeated failover?
A)There has been an increased level of VMFS activity.
B)The hosts are at the same patch level.
C)There are only four identical hosts in the vSphere cluster.
D)The virtual machines only have one vCPU.

A likely cause of fault-tolerance-related errors in this scenario is that there has been an increased level of VMFS activity. When virtual machines power on or off - for example, during a vMotion or when snapshoting takes place - the VMFS volume in question has an increased level of locking. This can cause fault-tolerant machines to failover as the VMkernel receives warning about SCSI reservations. To resolve this, you could place fault-tolerant machines on less densely populated VMFS volumes.
