Question #:1
Which three configuration scenarios are valid for the deployment of Prism Central? (Choose three.)
Environments use Network Address Translation.
Prism Elements and Prism Central art in different subnets.
Environments do not have Internet access.
Prism Elements and Prism Central have proxy configured.
Environments use the 192.168.5.0/24 CVM management network.
Answer: A B C
Explanation
Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix
environments1. Prism Central can be deployed in different configuration scenarios, depending on the network
and security requirements of the environment. Some of the valid scenarios are:
Environments use Network Address Translation (NAT): NAT is a method of mapping one IP address
space to another by modifying network address information in IP datagram packet headers while they
are in transit across a traffic routing device2. NAT can be used to enable communication between Prism
Central and Prism Elements that are in different networks or subnets3. For example, Prism Central can
be deployed in a public cloud and use NAT to access Prism Elements that are in a private data center3.
Prism Elements and Prism Central are in different subnets: A subnet is a logical subdivision of an IP
network that allows multiple networks to share a single physical network4. Prism Elements and Prism
Central can be in different subnets as long as they can communicate with each other through routing or
NAT3. For example, Prism Central can be deployed in a management subnet and access Prism Elements
that are in different application subnets3.
Environments do not have Internet access: Internet access is not required for the deployment of Prism
Central, as long as the environment meets the prerequisites and considerations for installing or
upgrading Prism Central. For example, Prism Central can be deployed in a dark site, which is an
environment that does not have Internet access or has restricted Internet access. In this case, the
administrator needs to manually enable microservices infrastructure and download the required software
packages from another source.
Question #:2

Reduce the amount of memory assigned to the VM.
Migrate the VM to a different host.
Add more memory to the VM.
Increase the memory on the CVM.
Answer: A
Explanation
According to the Troubleshoot high memory issues on Azure virtual machines web search result2, one of the
common factors in a low memory situation is over-provisioning memory for a VM. Over-provisioning
memory can cause memory pressure, which leads to swapping and degraded performance. Therefore, to fix
this issue, the administrator should reduce the amount of memory assigned to the VM, based on the average
hardware requirements for that operating system and application load.
Question #:3
In Nutanix clusters, which feature ensures VMs can be migrated and restarted on another host in case of
failure?
High Availability
Protection Domain
Host Affinity Rules
Availability Zone
Answer: A
Question #:4
An administrator needs to run a mixed Exchange and SQL workload with a guaranteed amount of container
space for each application.
How should the administrator meet this requirement?
Create one container and set capacity reservation
Create two containers and reserve space for containers
Create one container and enable compression
Create two containers and reserve space for vDisks

An administrator increases the cluster RF to 3. The containers are not modified.
What will the new values in the data resiliency dashboard be for FAILURES TOLERABLE for the Zookeeper
and Extent Groups components?
Zookeeper = 1 and Extent Groups = 1
Zookeeper = 2 and Extent Groups = 2

Zookeeper = 2 and Extent Groups = 1
Zookeeper = 1 and Extent Groups = 2
Answer: C
Explanation
According to the web search results, the cluster redundancy factor (RF) determines how many copies of the
cluster metadata and configuration data are stored on different nodes. By default, the cluster RF is 2, which
means that there are three copies of the Zookeeper and Cassandra data on the cluster. If the cluster RF is
increased to 3, then there will be five copies of the Zookeeper and Cassandra data on the cluster12. This means
that the Zookeeper component can tolerate two failures, as it can still operate with a quorum of three nodes out
of five3.
However, the container replication factor (RF) determines how many copies of the VM data and oplog are
stored on different nodes. The container RF can be set independently for each container, and it can be different
from the cluster RF. For example, a container can have RF 2 even if the cluster has RF 34. In this case, the
container will only have two copies of the VM data and oplog on the cluster, regardless of the cluster RF. This
means that the Extent Groups component can only tolerate one failure, as it needs at least one copy of the VM
data and oplog to be available5.
Therefore, if the administrator increases the cluster RF to 3, but does not modify the containers, then the new
values in the data resiliency dashboard will be Zookeeper = 2 and Extent Groups = 1.
Question #:7
Administrator is creating a Windows 10 VM that will be used for a virtual desktop template. After creating the
VM and booting to the ISO, the administrator is unable to install Windows and receives the following error.
What steps does the administrator need to take to install the OS?
Load the Nutanix VirtIO Serial Bus Driver.
Load the VirtIO Network Ethernet Adaper.
Load the Nutanix Virtual Balloon Driver.
Load the Virtual SCSI pass-through controller.
Answer: D

The error message shown in the image indicates that Windows 10 setup cannot find any drives to install the
OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through controller to present disks
to the VMs, and Windows 10 does not have a built-indriver for this device. Therefore, the administrator needs
to load the Nutanix VirtIO driver for the virtual SCSI pass-through controller during the OS installation
process. The Nutanix VirtIO driver package contains various drivers that are specifically used by Windows
VMs hosted in the Nutanix environment to enhance their stability and performance1. The administrator can
download the latest Nutanix VirtIO driver package from the VirtIO downloads page of the Nutanix support
portal. The administrator can then follow these steps to load the driver and install the OS2:
On the Windows 10 setup screen, click Load driver.
Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.
Browse to the location of the driver package and select the folder that matches the OS architecture
(32-bit or 64-bit).
Select the vioscsi.inf file and click Next.
Wait for the driver to load and then click Refresh.
Select the disk where you want to install Windows 10 and click Next.

Question #:8
A vDisk is read by multiple VMs. The cluster creates immutable copies of the vDisk. What are these vDisk
copies called?
Disk Clones
Golden Images
Volume Groups
Shadow Clones
Answer: D
Explanation
According to the Nutanix Support & Insights web search result3, shadow clones are vDisk copies that are
created by the cluster when a vDisk is read by multiple VMs. Shadow clones are immutable copies of a vDisk
that are stored in different nodes in the cluster, and are used to improve read performance and reduce network
traffic. Shadow clones are automatically created and deleted by the cluster, based on the demand and
availability of resources.

An administrator has an AHV cluster that is comprised of 4 nodes with the following configuration in each
node:
CPU:2 each 2.4GHz, 12 core
Memory: 256GB
Disk: 6 each 1.92 SSD
A VM with 16 vCPUs and 96GB of RAM is being created on the cluster.
How should the administrator configure the VM to assure optimal performance?
With an affinity policy
With memory overcommit
With 2 vNUMA nodes
With Flash Mode enabled
Answer: C
Explanation
The best way to configure the VM for optimal performance is to set it up with 2 vNUMA nodes. This will
ensure that the VM is configured to take advantage of the CPU and memory resources available in each node,
and it will also ensure that all of the cores are utilized for the best performance. Additionally, the administrator
should ensure that the VM has an affinity policy set up so that the vCPUs are evenly distributed across the four
nodes. Finally, Flash Mode should be enabled in order to take advantage of the high-performance SSDs that
are available in the cluster
Question #:10
An administrator wants to ensure that data in a container is stored in the most space efficient manner as
quickly as possible after being written,
Which space efficiency too meets this requirement?

inline compression is a technique that compresses all incoming write I/O operations over 4 KB inline in the
persistent write buffer (oplog) . This approach enables you to use oplog capacity more efficiently and helps23
drive sustained performance . From AOS 5.18 onward, inline compression (compression delay=0) is enabled2
by default for all new containers .24
