An ESXi host has be

en placed into Quarantine Mode by Proactive HA.

What will happen?

A. Virtual machines will be migrated off the quarantines host if doing so will not violate any DRS affinity and anti-affinity rules or cause increased resource contention.

B. Newly powered-

on virtual machines may be placed on the quarantined host to balance cluster resources. Already powered-on virtual machines will be migrated off of the quarantined host if doing so will not violate any DRS affinity and anti-affinity rules or cause resource

contention.

C. All virtual machines will be migrated off the quarantined host to other hosts in the cluster without regard to DRS rules.

D. vSphere HA will conduct a failover on all VMs residing on the quarantined host.

Explanation:

Proactive H

A

-” Proactive HA integrates with select hardware partners to detect degraded components and evacuate VMs from affected hosts

before

an incident can cause an interruption of service. vCenter Server plug-ins from the hardware vendors provide the health statu

s of hosts- system memory, local storage, power supplies, cooling fans, and network adapters. If components become degraded, Proactive HA determines which hosts are at risk and places them into a new-to-6.5 state called -Quarantine Mode-. While in Quaranti

ne Mode, VMs are migrated off of the host onto healthy hosts (as long as affinity and anti-affinity rules are not violated, and the performance of the VM will not be negatively affected). New VMs will not be added to hosts that are in Quarantine Mode.
