In a vSphere High Availability (vSphere HA) cluster, which action does vSphere HA take when the VM Monitoring service does NOT receive heartbeats from a virtual machine (VM) in the cluster?
When the VM Monitoring service in a vSphere High Availability (vSphere HA) cluster does not receive heartbeats from a virtual machine (VM), the typical action taken is to restart the VM on the same host in the cluster. This is to ensure that the VM's services remain available without the need to migrate it to a different host unless the host itself has failed. Restarting the VM on the same host helps in minimizing downtime and avoiding potential disruptions that might occur due to migration.
Using datastore heartbeating, the primary host determines whether a host has failed or a network isolation has occurred. If datastore heartbeating from the host stops, the host is considered failed. In this case, the failed host’s VMs are started on another host in the vSphere HA cluster. Answer: D
Sorry, correct Answer is: A
This option resets the VM.
After failures are detected, vSphere HA resets virtual machines. The reset ensures that services remain available. To avoid resetting virtual machines repeatedly for nontransient errors, by default, virtual machines will be reset only three times during a certain configurable time interval. After virtual machines have been reset three times, vSphere HA makes no further attempts to reset the virtual machines after subsequent failures until after the specified time has elapsed. You can configure the number of resets using the Maximum per-VM resets custom setting.
As you can see, it says that it will be restarted, not migrated or anything like that, hence the answer is: D. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-62B80D7A-C764-40CB-AE59-752DA6AD78E7.html
A would be true if there was a host isolation but this only refers to VMs.
As per this article, it will simply restart the VM and doesn't mention about moving the VM to a different host. https://blogs.vmware.com/vsphere/2014/03/vsphere-ha-vm-monitoring-back-basics.html
vSphere High Availability is a utility that pools the ESXi hosts and virtual machines into a cluster for monitoring and automatically restart failed virtual machines on alternative host to reduce application downtime and ensure business continuity. https://www.ubackup.com/enterprise-backup/vsphere-ha-virtual-machine-monitoring-action.html
may be D .. i am also confused now : (
It is VM monitoring service. It only resets the VM and in the same host. Hence D.
D is Correct
Correct answer is D, VM Monitoring service does NOT receive heartbeats from a virtual machine (VM) does not need to restart the VM to other host.
correct answer is A. The VM is restarted on a different host in the cluster.
But why? It is not ESXI host failing, only VM Failed. I believe correct answer is D, it just restarts the VM on the same host.
