Question 1

Which two capabilities does IPAM provide in a Nutanix networking configuration? (Choose two.)

AAllows proxy server settings to be set up for a defined network

BAllows AHV to assign IP addresses automatically to VMs using DHCP

CConfigures a VLAN with an IP subnet and assigns a group of IP addresses

DConfigures firewall rules to prevent or allow certain TCP/IP traffic

Answer : B, C

According to theNutanix Support & Insights, IPAM enables AHV to assign IP addresses automatically to VMs using DHCP. You can configure each virtual network and associated VLAN with a specific IP subnet, associated domain settings, and group of IP address pools available for assignment.

Question 2

A customer has a 24-node cluster with all containers configured with RF3. Two different nodes have incurred a simultaneous HDD failure.

What is the result?

AThe cluster runs in a degraded state until the failed drives are replaced and the data has been restored to three replicas.

BSixty minutes after the failures a rebuild of the lost data can remaining HDDs begins to restore to three replicas.

CThe VMs with data on those drives crash, and an HA event occurs, restarting them on a remaining healthy node.

DThe Nutanix cluster recognizes the failures and immediately begins to rebuild lost data to three replicas.

Answer : D

This is because Nutanix uses a distributed storage fabric (DSF) that replicates data across multiple nodes and drives to ensure data resiliency. When a drive fails, the cluster detects the failure and initiates a data rebuild process to restore the replication factor (RF) of the affected containers. The data rebuild process does not affect the availability or performance of the VMs, as they can still access their data from other replicas on other nodes or drives. Therefore, there is no need to wait for 60 minutes, use a shared volume group, or trigger an HA event.

Question 3

Refer to Exhibit:

An administrator wants to replace and old node with a node of newer generation in a 3-node cluster. The administrator has already chosen the appropriate node. But unable to remove it from the cluster.

Why is the Remove Host option not shown in the exhibit?

AThe host needs to be placed into maintenance Mode before.

BIt is only possible to remove a host from a cluster using CLI.

CIt is not possible to remove a node from a the cluster using Prism Central

DIt is not possible to remove a host from a 3-node cluster.

Answer : D

A Nutanix cluster requires a minimum of three nodes to maintain quorum and data availability. Removing a node from a 3-node cluster would violate the redundancy factor and cause data loss. Therefore, it is not possible to remove a host from a 3-node cluster using Prism or CLI.The only way to replace a node in a 3-node cluster is to use the Foundation tool, which will erase the existing cluster configuration and create a new cluster with the new node1.

Question 4

An administrator is concerned about the amount of data that a VM reading and writing to the storage fabric.

Which metric will provide that data?

AHost Hypervisor IO Bandwidth

BHost Disk IOPS

CVM Storage Controller IOPS

DVM Storage Controller Bandwidth

Answer : D

The correct answer is D. VM Storage Controller Bandwidth.

VM Storage Controller Bandwidth is a metric that measures the amount of data that a VM is reading and writing to the storage fabric. The storage fabric is the network of storage controllers (CVMs) that provide distributed and fault-tolerant storage services to the VMs on the Nutanix cluster. The VM Storage Controller Bandwidth metric shows the read and write bandwidth in megabytes per second (MBps) for each VM. The higher the bandwidth, the more data the VM is transferring to and from the storage fabric1.

The administrator can use Prism Central to view the VM Storage Controller Bandwidth metric for each VM in a chart or a widget. The administrator can also use Prism Central to view other metrics related to the VM's storage performance, such as VM Storage Controller IOPS, VM Storage Controller Latency, and VM Disk Usage2.

Question 5

How should an administrator enable secure access to Volumes using a password?

AiSER

BCHAP

CSAML

DLDAP

Answer : B

Provision storage on the Nutanix cluster by creating a volume group. Create a client whitelist to enable access to the volume group by using the IP addresses or client initiator IQNs in a whitelist (as part of the volume group configuration). Create a secret for the volume group if you are using CHAP authentication.

Question 6

While installing Windows 2019 on a new VM on an AHV cluster, an administrator notices there aren't any drives listed for the install.

What might the problem be?

AVirtIO drivers have not yet been installed and the disks are IDE disks.

BVirtIO drivers have not yet been installed and the disks are SCSI disks.

CVirtIO drivers must be installed on AHV for installations of Windows.

DVirtIO drivers aren't supported on this version of Windows 2019.

Answer : B

VirtIO drivers are device drivers that are specifically designed for virtualized environments. They allow the guest operating system to communicate directly with the underlying hardware, bypassing the emulation layer. This improves the performance and efficiency of the virtual machines.VirtIO drivers are supported by various hypervisors, including Nutanix AHV1.

Nutanix AHV uses SCSI disks for VMs by default. However, Windows does not have native support for SCSI disks and requires VirtIO drivers to recognize them. Therefore, if an administrator is installing Windows 2019 on a new VM on an AHV cluster, they need to install the VirtIO drivers before selecting the destination disk for the installation.Otherwise, they will not see any drives listed for the install2.

To install the VirtIO drivers during Windows installation, the administrator can use one of the following methods3:

Use a VirtIO ISO image that contains the driver files. The administrator can download the VirtIO ISO image from the Nutanix support portal and upload it to the AHV image service. Then, they can attach the VirtIO ISO image to the VM as a CD-ROM device and load the driver from it during Windows installation.

Use a Nutanix Guest Tools (NGT) ISO image that contains the driver files and other tools. The administrator can download the NGT ISO image from Prism Element or Prism Central and attach it to the VM as a CD-ROM device. Then, they can load the driver from it during Windows installation.

Use a floppy disk image that contains only the driver files. The administrator can create a floppy disk image using tools such as WinImage or WinRAR and upload it to the AHV image service. Then, they can attach the floppy disk image to the VM as a floppy device and load the driver from it during Windows installation.
