How will an HDD failure affect VMs with data on the failed device?
A. The VMs will crash, and will be restarted once the failed HDD has been replaced and the data has been restored.
B. A live migration will be initiated, moving the affected VMs to a host that contains the replica data.
C. The VMs will remain operational on that host and continue to function normally with no noticeable impact
D. An HA event will occur, causing the affected VMs to restart on a node that contains the replica data.
Explanation: According to the Troubleshooting hosted disk I/O performance problems (1008885), when using VMware hosted products, consider that both the virtual machines and host operating system often share the same disk resources and hardware. If a hard disk fails, the virtual machines that have data on the failed device will experience an HA event, causing them to restart on a node that contains the replica data.
A VM in a 12-node Nutanix cluster is hosting an application that has specific Physical GPU requirements. Only three nodes in the cluster meet this requirement.
The administrator wants to allow a general workload to be distributed across all nodes in the cluster and must make sure that the node hosting the VM meets its requirements.
How should the administrator perform this task?
A. Create a sperate three-node cluster using the nodes that meet the requirement.
B. Configure VM-Host affinity for the nodes that meet the application's GPU requirement.
C. Over-Provision the application VM with additional virtual GPUs.
D. Configure anti-affinity rules between the application VM and the other VMs running on the cluster.
Explanation: Configure VM-Host affinity for the nodes that meet the application’s GPU requirement. This is because VM-Host affinity allows the administrator to specify which nodes a VM can run on or must not run on1. By creating a VM-Host affinity rule that binds the application VM to the three nodes that have the physical GPU, the administrator can ensure that the VM will always run on a node that meets its requirement, regardless of any HA or migration events. This also allows the other nodes in the cluster to host other VMs without any restrictions.
When VM HA Reservation is enabled, what is the expected behavior for all failed VMs in the event of a host failure?
A. Restart on a best-effort basis if resources are available
B. Perform a live migration to other hosts in the AHV cluster
C. Restart on other hosts in the AHV cluster
D. Perform a live migration on a best-effort basis if resources are available
Which method can be used to migrate a VM configured for UEFI-boot from a Nutanix Hyper-V cluster to AHV?
A. Live Migration
B. Storage vMotion
C. Nutanix Move
D. Cloud Connect
Explanation:
Nutanix Move is a tool that allows you to migrate VMs from different sources to Nutanix AHV with minimal downtime and complexity. Nutanix Move supports migration from Hyper-V to AHV, including VMs configured for UEFI-boot. UEFI stands for Unified Extensible Firmware Interface, which is a standard for the software interface between the operating system and the firmware. UEFI-boot is a mode of booting that uses UEFI instead of BIOS (Basic Input/Output System) to load the operating system. UEFI-boot offers some advantages over BIOS-boot, such as faster boot time, larger disk support, and better security features1.
To migrate a VM configured for UEFI-boot from a Nutanix Hyper-V cluster to AHV, you need to use Nutanix Move and follow these steps2:
Download and deploy the Nutanix Move appliance on the AHV cluster.
Log in to the Nutanix Move web console and add the source Hyper-V environment and the target AHV environment.
Create a migration plan and select the VMs that you want to migrate. You can choose either automatic or manual preparation mode for the migration.
Start the migration plan and monitor the progress. The migration plan will perform data seeding, which is the process of copying the VM data from the source to the target in the background.
When the data seeding is complete, perform a cutover, which is the process of shutting down the source VMs and powering on the target VMs. The cutover will also configure the boot device for the UEFI-boot VMs on AHV.
Verify that the migrated VMs are working as expected on AHV.

What is the function of the virbr0 bridge on AHV?
A. To carry all traffic between the user VMs and the upstream network.
B. To carry management and storage communication between user VMs and the CVM.
C. To carry management and storage communication between user VMs and AHV host.
D. To carry storage communication between the guest VMs and the CVM
