Nutanix Certified Professional (NCP) — Question 11

A Nutanix cluster is equipped with four nodes. Four VMs on this cluster have been configured with a VM-VM anti-affinity policy and are each being hosted by a different node.
What occurs to the cluster and these VMs during an AHV upgrade?

Answer options

• A. One VM out of the four powers down when the node hosting it reboots
• B. The AHV pre-upgrade checks fail until the four VMs are powered off
• C. The AHV pre-upgrade checks fail until the administrator disables the anti-affinity policy
• D. One node hosts two VMs while the node being upgraded is in maintenance mode

Correct answer: C

Explanation

The correct answer is C because during an AHV upgrade, the pre-upgrade checks require that the anti-affinity policy be disabled to allow for proper VM migration. Option A is incorrect as no VM powers down automatically; they remain running on their respective nodes. Option B is wrong because the checks can pass if the anti-affinity policy is disabled without powering off the VMs. Option D is also incorrect since no node can host more than one VM during this scenario due to the anti-affinity policy.
