An administrator is using EUC broker software to manage and direct connections to virtual desktops and applications. After losing power to a host in the cluster, the administrator needs to make sure the broker VMs restart. What will happen to the broker VMs in this situation?

Nutanix AHV includes a built-in High Availability (HA) feature that is enabled by default. In the event of an unplanned host failure, such as a power loss, the Acropolis leader detects the failure. It then automatically restarts the virtual machines that were running on the failed host on other healthy hosts within the cluster. This process ensures that critical services, like EUC connection brokers, are brought back online with minimal downtime without requiring manual intervention or pre-configured policies beyond the default settings.

A. The VMs will remain powered off until the host is back online: This is incorrect. The purpose of AHV HA is to automatically recover VMs on other hosts.
B. A policy must be created so the VMs will power back on: The HA functionality is built-in and enabled by default on AHV clusters; no special policy is needed for this restart behavior.
D. The VMs will live migrate to a powered-on host: Live migration is a proactive, planned movement of a running VM. In a sudden host failure, VMs are restarted, not live-migrated.
