When host affinity policies are enabled, how does this affect AHV cluster?
The VM-host affinity cannot be applied on a cluster that has HA reservations configured. VM-host affinity has specific limitations, notably that it cannot be configured on a cluster where high availability (HA) is set up using reserved host methods. This restriction ensures that the HA policies can function correctly, as reserved hosts need to be freely available to handle failovers and cannot be constrained by VM-affinity rules.
correct answer D . VM-host affinity can not be configure if the HA is configured using the reserved method.
Limitations fo affinity Rules: 1 - If a host is removed from a cluster, the host UUID is not removed from the host-affinity list. 2- The host affinity can not be configured on a cluster that has HA configured using the reserved host method. 3- You cannot remove the VM-hosts affinity for a powered-on VM on Prism. So the correct option is D.
The questions "When host affinity policies are ENABLED", IMHO this goes beyond the fact that VM-host affinity can not be configured, as they are already enabled. So why D?
I'm not really sure of this one. In 5.16 the limitation included : The VM-host affinity cannot be configured on a cluster that has the HA configured by using reserved host method. -> https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_16:ahv-affinity-policies-c.html But it's been removed in last version -> https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v6_5:ahv-affinity-policies-c.html So, I will go for B
Answer might be D
B. Only limitation is "Even though if a host is removed from a cluster, the host UUID is not removed from the host-affinity list for a VM." : https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v6_0:ahv-affinity-policies-c.html
D is correct
D is correct
