VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is reviewing vSphere HA settings and notices that 'Host Isolation Response' is set to 'Power Off'. What happens to virtual machines running on an ESXi host if that host becomes network-isolated from the rest of the cluster?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
vSphere HA powers off the virtual machines on the isolated host and attempts to restart them on surviving hosts in the cluster.
When an ESXi host is network isolated and the isolation response is set to Power Off, vSphere HA powers off the virtual machines on that host so they can be restarted on surviving healthy hosts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The isolated host immediately reboots its physical motherboard.
Why it's wrong here
Host reboot occurs if the isolation response is set to Power Off and Reset, but the isolation response specifically targets the VMs.
- ✗
Virtual machines remain running in an isolated sandbox with no access to shared storage.
Why it's wrong here
That describes the 'Leave powered on' isolation response.
- ✓
vSphere HA powers off the virtual machines on the isolated host and attempts to restart them on surviving hosts in the cluster.
Why this is correct
Powering off ensures safe shutdown before restarting workloads on healthy cluster nodes during network isolation.
- ✗
DRS automatically migrates the isolated host to a secondary management network.
Why it's wrong here
DRS does not manage network isolation responses.
