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





C.
  Nutanix Move

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





C.
  To carry management and storage communication between user VMs and AHV host.

A customer wants to isolate a group of VMs within their Nutanix environment for security reasons. The customer creates a VM with two NICs to act as a firewall and installs the appropriate software and certificates.
However, no one from the outside can access the application.
What is the likely cause of this problem?


A. A shared volume group must be used by all isolated VMs


B. More than one NIC cannot be added to a VM


C. One of the NICs needs to be configured on the internal VLAN


D. Wireshark is installed on the NAT VM





C.
  One of the NICs needs to be configured on the internal VLAN

Explanation: One of the NICs needs to be configured on the internal VLAN. This is because the VMs that are isolated need to communicate with the firewall VM through a private network, and the firewall VM needs to communicate with the external network through a public network. The internal VLAN is a logical network that can be created and managed by AHV1. If the firewall VM does not have a NIC on the internal VLAN, it will not be able to route traffic between the isolated VMs and the outside world.

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?


A. One node hosts two VMs while the node being upgraded is in maintenance mode.


B. One VM out of the four powers down when the node hosting it reboots.


C. The AHV pre-upgrade checks fail until the administrator disables the anti-affinity policy.


D. The AHV pre-upgrade checks fail until the four VMs are powered off.





A.
  One node hosts two VMs while the node being upgraded is in maintenance mode.

Explanation: One node hosts two VMs while the node being upgraded is in maintenance mode. This is because Nutanix supports a feature called Rolling Upgrade that allows upgrading AHV on a cluster without any downtime or impact to the VMs. The Rolling Upgrade feature performs the upgrade one node at a time, by putting the node in maintenance mode, evacuating the VMs to other nodes, upgrading AHV, and then bringing the node back online. The VM-VM anti-affinity policy ensures that the four VMs are not placed on the same node during the evacuation process, so one node will host two VMs temporarily while the other node is being upgraded.

An administrator needs to bring down a host in a Nutanix Cluster for maintenance reasons. The administrator puts the host in maintenance mode.

What should the administrator do to perform an orderly shutdown of the CVM?


A. Execute the cvm_shutdown -P new command from the CVM.


B. Enter Fever off Server - immediate from the IPMI console.


C. Enter Fewer off Server-orderly Shutdown from the IPMI console.


D. Execute the cvm_shutdown -P now command from the host.





A.
  Execute the cvm_shutdown -P new command from the CVM.

Explanation: According to the How to use the cvm_shutdown script web search result3, the cvm_shutdown script signals HA when shutting down the CVM (Controller VM) to forward the storage traffic to another healthy CVM. Instead of using sudo shutdown or sudo reboot commands, this script should be used to minimize I/O hits in user VMs running on the present hypervisor host. The cvm_shutdown -P now command will initiate the shutdown process on the CVM immediately. Therefore, if the administrator needs to perform an orderly shutdown of the CVM, they should execute this command from the CVM.

A guest VM should be able to tolerate simultaneous failure of two nodes or drives.
What are the minimum requirements for the Nutanix cluster?


A. 3 nodes with cluster RF 3 and container RF 3


B. 3 nodes with cluster RF 3 and container RF 2


C. 5 nodes with cluster RF 2 and container RF 3


D. 5 nodes with cluster RF 3 and container RF 3





D.
  5 nodes with cluster RF 3 and container RF 3

Where are Leap Availability Zones configured?


A. Cloud Connect


B. Controller VM


C. Prism Element


D. Prism Central





D.
  Prism Central

Explanation:
Terminology
Availability Zone – it is represented by all resources (Nutanix Clusters) connected to Prism Central or Xi Leap Availability zone. Depends on the architecture, Availability zone can represent geographic territory, datacenter or server room in the datacenter. Protection policies – in protection policies you set up (RPO, Retention), rules to auto-apply policies to virtual machines.

When installing Nutanix Guest Tools (NGT) on an ESXi-hosted VM, which port should be enabled on the VM to allow communication with the NGT-Controller VM service?


A. 2000


B. 2074


C. 8080


D. 9943





D.
  9943

Explanation: NGT is a software package that enables advanced VM management features provided by Nutanix, such as file-level restore, VM mobility, and application-consistent snapshots12. To use NGT, you need to enable the NGT feature for a VM in the Prism Element web console, mount the NGT installer (ISO disk file) in the VM, and install NGT in the VM1. However, before installing NGT, you need to ensure that the VM can communicate with the NGT-Controller VM service, which runs on the Controller VM (CVM) of each Nutanix node3. The NGT-Controller VM service listens on port 9943 for incoming requests from the guest VMs3. Therefore, you need to enable port 9943 on the ESXi-hosted VM to allow communication with the NGT-Controller VM service.

An administrator needs to limit the amount of storage space that data stored in single container can consume.

Which action should the administrator take?


A. Enable reservation for rebuild capacity


B. Set an advertised capacity for the container


C. Store VM snapshots in a different container


D. Thick prevision the container





B.
  Set an advertised capacity for the container

Explanation: The best way for the administrator to limit the amount of storage space that data stored in a single container can consume is to set an advertised capacity for the container. This will ensure that the data stored in the container doesn't exceed the set limit, and it will also help prevent any potential performance issues due to resource contention. Additionally, the administrator should consider thick provisioning the container, which will pre-allocate the amount of storage space that can be used by the container. This will help ensure that the data stored in the container doesn't exceed the advertised capacity.

What is the minimum time a newly created Deduplication storage policy takes to apply to the VMs in the container?


A. 5 Minutes


B. 10 minutes


C. 30 minutes


D. 60 minutes





C.
  30 minutes
