Explanation
The correct answer is B because setting VM-Host affinity ensures that the DB Server VMs are not migrated to another host during the LCM upgrade process. This way, the DB Server VMs can continue to serve the database requests without interruption. Option A is incorrect because updating the Nutanix cluster does not prevent the DB Server VMs from being moved to another host. Option C is incorrect because removing the Nutanix cluster from NDB will make the DB Server VMs unmanaged by NDB and lose the benefits of NDB features. Option D is incorrect because unsetting VM-Host affinity will allow the DB Server VMs to be migrated to another host during the LCM upgrade process, which may cause downtime or performance degradation.
