Using vSphere HA Orchestrated Restart an administrator places the most mission critical VM in the highest priority. After a host failure, the highest priority VM fails to restart while VMs in high priority restart. What would cause this to occur?
A. There are insufficient cluster resources.
B. Performance degradation VMs tolerate threshold is at default.
C. VMware Tools is not installed.
D. Proactive HA is disabled.
Correct answer is A
it says, “After a host failure, the highest priority VM fails to restart…” VMware tools has nothing to do with powering a VM, only to find out Guest hartbeat detection. It has to that the cluster with one less host does not have the reasources to start that VM.
I’m going with C. All Proactive HA does is monitor host hardware to “proactively” move the VMs based on the thresholds set. If the other VMs restart, this rules out D. If VMWare Tools are not installed on the highest priority VM, HA will initiate a reset (hard reboot) vs a restart (tells guest to “nicely” reboot) which requires guest os level communication via VMware Tools.
