End User Computing
Question 1
An administrator is deploying a new virtual desktop environment onto an existing Nutanix solution.
The virtual desktop environment will consist of these elements:
1000 instant clone call center virtual desktops (supporting 5 business units)
500 full clone developer virtual desktops (supporting 2 business units)
150 applications delivered via AppStacks (supporting 7 business units)
How many storage containers should be created to support these workloads?
- A. 1
- B. 2
- C. 3
- D. 14
Answer:
C
Explanation:
Based on the given information, the administrator is deploying 1000 instant clone virtual desktops,
500 full clone virtual desktops, and 150 applications. To support these workloads, the Nutanix
solution will need multiple storage containers.
According to the Nutanix Certified Professional - End User Computing (NCP-EUC) v6 guide, for VDI
workloads, it is recommended to create a separate storage container for each type of desktop (e.g.
instant clone, full clone) and another container for AppStacks. It is also recommended to have at
least one container for metadata and one container for replicas.
Therefore, for this scenario, a total of 3 storage containers should be created:
One container for 1000 instant clone virtual desktops
One container for 500 full clone virtual desktops
One container for 150 applications delivered via AppStacks
So the answer is C. 3.
Question 2
Refer to the exhibit.
An administrator is deploying an Instant Clone desktop pool on an 8-node Nutanix cluster. The
system displays a warning message, as shown in the exhibit.
What should the administrator do to resolve the issue?
- A. Enable View Storage Accelerator
- B. Safely ignore this warning
- C. use both VSA and Shadow Clones
- D. Disable Shadow Clones
Answer:
D
Explanation:
Shadow Clones are a unique feature of the AOS storage that enables distributed caching of virtual
disks (vDisks) used by virtual machines1
.
Shadow Clones provide effective caching optimization in
distributed multireader scenarios, such as large VDI and cloud deployments2
.
The warning message you see indicates that Shadow Clones are disabled on your Nutanix cluster.
This may affect the performance of your Instant Clone desktop pool, as it will not benefit from the
caching optimization provided by Shadow Clones.

Question 4
How should an administrator protect Writable AppVolumes during a disaster in a Nutanix
environment?
- A. Create a storage container in both the primary and DR data centers for the Writeable AppVolumes. Set up asynchronous DR between the two sites.
- B. Enable HA reservations on the cluster to ensure there is capacity in case of failure.
- C. Disable HA reservations to ensure that VMS are powered on using best effort during a disaster,
- D. Create a protection domain and add the AppVolumes VM entities to it. Set up a schedule to replicate the VMS every 60 minutes.
Answer:
A
Explanation:
Writable AppVolumes are a feature of VMware App Volumes that provides users with a dedicated
virtual disk for storing user profile data and user-installed applications1
.
Writable AppVolumes are
stored as VMDK files on a datastore2
.
To protect Writable AppVolumes during a disaster in a Nutanix environment, one possible solution is
to use asynchronous DR between two sites.
Asynchronous DR allows you to replicate VMs and their
associated data from one site to another at regular intervals using protection domains and remote
sites3
.

Question 5
An administrator has been asked to enable mufti-monitor support for a graphic designer that needs
to be able to use four monitors.
After on boarding the designer on to the Frame desktop, the end user does not see the ability to use
all four monitors while using the Firefox web browser.
What should the administrator do to enable the ability to use all four monitors?
- A. Switch to Chrome
- B. Deploy Frame App
- C. Switch to Edge
- D. Switch to Safari
Answer:
B
Explanation:
According to Nutanix documentation, to use more than two monitors with Frame, you need to
deploy the Frame App. The Frame App provides multi-monitor support, whereas using Frame
through web browsers is currently limited to two monitors.
Frame App is a native application that provides a better user experience for accessing Frame
desktops and applications than a web browser1
. Frame App supports the Frame multi-monitor
feature automatically.
If an end user has more than one monitor attached to their device, Frame App
prompts the user if they want to use all of their monitors1
.
Frame Administrators do not have to
enable explicitly multi-monitor support for Frame App users1
.
Question 6
An administrator has finished deploying the Citrix backend infrastructure to Xi Leap and needs to
expose the Citrix NetScaler VPX private VIP to the internet in order for users to be able to access the
Citrix VDI desktops upon a DR failover.
What should the administrator perform in order for public internet access to be allowed to the Citrix
NetScaler VPX?
- A. Floating IP Address
- B. FQDN registered in DNS.
- C. Disaster recovery node configured in HA mode.
- D. Executing /mps/deployment _ type.Py
Answer:
A
Explanation:
Citrix NetScaler VPX is a virtual appliance that provides web and application load balancing, secure
and remote access, acceleration, security and offload features
. To set up and configure a Citrix
NetScaler VPX appliance, you need to download it from the Citrix website, install it on a hypervisor
such as Citrix XenServer or Microsoft Azure
, and log on to the console using the nsroot
credentials
.
To expose the Citrix NetScaler VPX private VIP to the internet in order for users to be able to access
the Citrix VDI desktops upon a DR failover, one possible solution is to use a floating IP address. A
floating IP address is an IP address that can be dynamically assigned to an instance by using API calls.
It allows you to redirect network traffic from one instance to another without changing any DNS
settings or client configuration.
Question 7
Recently, the vice president Of IT infrastructure was migrated from a physical computer to a virtual
desktop. The administrator wants to ensure that this user has the best possible experience and wants
to be notified if any CPU resource constraints.
The cluster's average CPU utilization is 20%.
What step would help the administrator to know when there are resource problems on the virtual
desktop?
- A. Create a new alert policy to alert if the CPU on the virtual desktop is over and configure a Playbook to power off the virtual desktop.
- B. Create a new alert policy to alert if the CPU on the virtual desktop is over and configure a Playbook to Slack the information to the administrator,
- C. Create a new alert policy to alert if the CPU on the virtual desktop's host is over 90%.
- D. Create a new alert policy to alert if the CPU on the virtual desktop's cluster is over 90%.
Answer:
B
Explanation:
alert policies are rules that define the conditions for generating alerts on Nutanix clusters
.
You can
create custom alert policies based on your specific needs and preferences2
Playbooks are automated
workflows that perform actions based on triggers such as alerts
.
You can create playbooks using
predefined alerts or alerts matching criteria3
.
To ensure that the vice president of IT infrastructure has the best possible experience and to be
notified if any CPU resource constraints on the virtual desktop, one possible solution is to create a
new alert policy to alert if the CPU on the virtual desktop is over a certain threshold (for example,
80%) and configure a playbook to send a notification (for example, via email or Slack) to the
administrator
. This way, the administrator can monitor the performance of the virtual desktop and
take appropriate actions if needed.

Question 8
An administrator received a report that users are being disconnected from their sessions consistently
after IO minutes. The administrator suspects the gold image is incorrectly configured,
Which action should the administrator take to resolve this issue?
- A. Disable the monitor power saving settings.
- B. Sysprep the gold image with the CopyProfile set to True.
- C. Disable hard drive power saving settings.
- D. Uninstall and remove the Windows Store applications.
Answer:
B
Explanation:
gold image is a term used to describe a template for a virtual machine (VM) that contains a
preconfigured operating system and applications1
.
A gold image can be used to create multiple
session hosts that share the same configuration1
.
However, a gold image needs to be properly
prepared before being used as a template123
.
One of the steps involved in preparing a gold image is to run sysprep on the VM.
Sysprep is a tool
that removes system-specific data such as computer name, security identifier (SID), and driver cache
from Windows23
. This allows the VM to be generalized and duplicated without causing conflicts or
errors
.
One of the options that can be set when running sysprep is CopyProfile. CopyProfile is a setting that
determines whether the user profile settings of the built-in administrator account are copied to the
default user profile
. The default user profile is used as a template for creating new user profiles on
Windows
. If CopyProfile is set to True, then any changes made by the administrator account (such
as desktop wallpaper, screen saver, Start menu items, etc.) will be applied to all new user profiles
.
Therefore, if users are being disconnected from their sessions consistently after 10 minutes, it could
be because the gold image has some incorrect settings in the default user profile that cause session
timeout or termination. To resolve this issue, one possible solution is to sysprep the gold image
with CopyProfile set to True, and make sure that there are no settings in the administrator account
that could affect session stability (such as power saving options or Windows Store applications)
.
Question 9
Where should an administrator configure AWS, Azure, and Google accounts within Frame?
- A. Customers
- B. Organizations
- C. Cloud Account
- D. accounts
Answer:
C
Explanation:
Frame is a cloud-native desktop-as-a-service platform that delivers virtual apps and desktops from
multiple public clouds
. Frame allows administrators to manage various components of their cloud
accounts easily from the Frame console
.
A cloud account is a logical grouping of resources that are associated with a specific cloud provider
(such as AWS, Azure, or Google) and region
. A cloud account can have multiple virtual networks,
master images, and instance types that can be used to create and run virtual apps and desktops
.
To configure AWS, Azure, and Google accounts within Frame, an administrator needs to go to
the Cloud Accounts section of the Frame console
. There, the administrator can add new cloud
accounts or edit existing ones by providing the required credentials and settings for each cloud
provider
.

Question 10
A company has decided to use Citrix Optimizer tool to prepare their gold image.
Which two actions does Optimizer take to improve the gold image creation process? (Choose two.)
- A. Optimizes storage capacity usage.
- B. Optimizes user environments for better performance
- C. uses built-in templates to perform optimizations.
- D. Applies best practices for securing virtual desktops.
Answer:
BC
Explanation:
The Citrix Optimizer tool is used to prepare Windows operating system images for use in a virtual
desktop environment. Some of the actions that it takes to improve the gold image creation process
include:
Optimizes user environments for better performance: The tool removes unnecessary or redundant
services, features, and applications from the image, which can improve performance and reduce
resource usage.
Uses built-in templates to perform optimizations: The tool comes with pre-configured templates that
are optimized for specific environments, such as virtual desktops or server workloads. These
templates can be customized based on the specific needs of the organization.

Question 11
How should the storage containers be configured to follow Nutanix storage best practices?
- A. Use a single container. Enable Compression and Deduplication for both VMS
- B. Use separate containers. Enable Compression for non-persistent VMS. Enable Compression and Deduplication for persistent VMS
- C. Use a single container. Enable Compression and Erasure Coding for both VMS
- D. Use separate containers. Enable Compression for persistent VMS. Enable Compression and Deduplication for nan-persistent VMS
Answer:
B
Explanation:
Nutanix recommends using separate containers for persistent and non-persistent VMS. For
persistent VMS, enable compression and deduplication.
For non-persistent VMS, enable compression
only1
According to Nutanix documentation, it is recommended to use multiple containers, with each
container representing an individual performance workload. This allows for better performance
isolation and easier management. For example, one container could be used for VDI workloads,
while another container could be used for general-purpose workloads.
As for compression and deduplication, it is recommended to enable them for all VMs. Compression
reduces the amount of storage space required and increases the performance of the system, while
deduplication reduces the amount of duplicate data stored on the system. Erasure coding can also be
used as an alternative to replication for data protection.
Question 12
An administrator needs to deploy virtual desktops to a Hyper-V Nutanix cluster with writable
differencing disks, The administrator will use read only master image with clones that link back to the
image.
Which native feature will the cluster use to complete this task?
- A. Oplog
- B. Compression
- C. VM Flash Mode
- D. Shadow Clones
Answer:
D
Explanation:
The feature in Nutanix that would be used to complete the task of deploying virtual desktops to a
Hyper-V Nutanix cluster with writable differencing disks using a read-only master image with clones
that link back to the image is Shadow Clones. Shadow Clones allow for the creation of a snapshot or
a clone of a VM that uses the original VM's disks as read-only, and only writes changes to a separate
differencing disk. This is useful when deploying virtual desktops as it can reduce storage
requirements and improve performance.
Nutanix shadow clones are a feature that enables distributed caching of virtual disks (vDisks) that are
in a multi-reader scenario.
This can improve performance and reduce network traffic for scenarios
such as VDI or private clone boot storms1
Question 13
A Windows IO VM fails to power on With an NVIDIA vCPU profile in ESXi 7. The VM is configured with
NVIDIA profile by selecting Shared PCl Device, adding the NVIDIA GRID vCPU device. and selecting
the Profile under VM settings.
The following error message is displayed in the vSphere web client:
What should be done to resolve this issue?
- B. Change the Graphics mode of the host from Shared to Shared Direct
- C. Switch the GPU mode to graphics mode using gpumodeswitch command.
- D. change the Graphics mode of the host from Shared Direct to Shared.
- E. Switch the GPU mode to compute mode using gpumodeswitch command.
Answer:
C
Explanation:
gpumodeswitch is a command-line tool that is used to switch supported NVIDIA GPUs between
compute and graphics mode. Compute mode allows multiple VMs to share a GPU for CUDA
workloads.
Graphics mode allows a single VM to use a GPU for graphics workloads12
.
Question 14
An administrator supports a user group that spans across 10 Nutanix clusters for a medium-sized
medical communications firm. The 10 Nutanix clusters are managed by a single Prism Central
instance.
This group's virtual desktops are all cloned from a common gold image and all applications are
published from a Citrix Virtual Apps farm. The administrator needs to keep the gold image in sync
across all of the clusters.
What is the best way to achieve this?
- A. use the native replication facility within the Machine Catalog
- B. Setup a Protection Domain with the gold image as 3 protected entity.
- C. Upload the gold image to Prism Central Image Service.
- D. use Move to maintain all gold images across the clusters.
Answer:
C
Explanation:
Prism Central Image Service allows you to upload and manage images through Prism Central by
using the v3 API.
You can also choose where your images will be available across different clusters123

Question 15
An administrator has been evaluating a performance issue with the current Citrix VD' solution on
Nutanix. During the evaluation, the administrator finds out there is a feature that is enabled called
Shadow Clones.
What would happen if an administrator disabled Shadow Clones within a company's VDI
environment?
- A. Deployment times would increase as the number deployed desktops increase,
- B. Deployment times would decrease when deploying additional desktops.
- C. Boot storms would be eliminated due to desktop resource contention.
- D. Boot storms would be eliminated because the number of desktops would be throttled.
Answer:
A
Explanation:
Nutanix's Shadow Clones feature is used to create linked clones or snapshots of base VMs, which can
improve VM provisioning time and storage efficiency by reducing the amount of duplicated data.
If an administrator disables Shadow Clones within a company's VDI environment, it is likely that
deployment times would increase as the number of deployed desktops increases. This is because
linked clones or snapshots would no longer be used, so each new desktop deployment would require
creating a full copy of the base VM.
Nutanix Shadow Clones allow for distributed caching of a particular disk or VM data, which are in a
‘multi-reader’ scenario.
This can help in scenarios such as VDI or private clone boot storms, where
VMs on multiple nodes read from the same set of base disks12
