1Y0-403 Citrix Practice Test Questions and Exam Dumps

Question 1

Currently, the user interface for a Citrix Apps and Desktops environment is presented in English, but a planned on-premises expansion in Poland will support 100 new users with a requirement to use all Polish interfaces. Two constraints were identified by a Citrix Architect:

Network bandwidth is low and unstable.
Network latency is higher than 300 ms to the existing Site.

How should the architect deploy Citrix Virtual Apps and Desktops for these users?

A. Install a StoreFront server in Poland.
B. Implement Citrix Cloud Gateway in Europe.
C. Add a Satellite Zone to the existing Site.
D. Create a new Site in Poland.

Correct Answer: D

Explanation:

In this scenario, the key constraints are high latency (300+ ms) and unreliable bandwidth between Poland and the existing Citrix Site, which can severely impact user experience, especially in Virtual Apps and Desktops environments. Additionally, there's a language localization requirement to present Polish interfaces, which implies not only UI but also regional customization that may be best served independently.

Why “Create a new Site in Poland” is the best approach

When latency exceeds 250 ms, Citrix best practices recommend deploying a separate Site to avoid performance degradation. This is because:

Control and data traffic between zones in a single Site can become inefficient and impact user logon times, application responsiveness, and session reliability when the latency is high.
A Satellite Zone shares the Site infrastructure and relies on communications with the main zone for brokering, monitoring, and configuration, which does not perform well over unstable networks with high latency.
A new Site allows local control infrastructure (Delivery Controllers, StoreFront, Director, etc.) to operate independently, avoiding reliance on high-latency WAN links.
The requirement for full Polish interface support can also be configured locally in Poland, including Group Policy Objects (GPOs), language packs, and localized delivery groups.

Why the other options are less appropriate

A. Install a StoreFront server in Poland: While this could help improve authentication and app enumeration speeds, it doesn’t solve the underlying issue of high latency to the existing control plane (Delivery Controllers and database). StoreFront alone doesn’t reduce backend communication problems.
B. Implement Citrix Cloud Gateway in Europe: While using Citrix Cloud services may offer geographic flexibility, this scenario refers to an on-premises expansion, not a cloud-based solution. Also, Gateway services don’t address internal site replication and latency issues.
C. Add a Satellite Zone to the existing Site: This approach is feasible only when latency is below 250 ms and bandwidth is sufficient, neither of which applies here. Satellite Zones still depend heavily on the primary zone's controllers, so this would perform poorly under the given constraints.

Given the high latency and unreliable bandwidth, and the need for localized functionality and language support, the most robust and scalable solution is to deploy a new, independent Citrix Site in Poland.

Question 2

A planning document for deploying a new Citrix Virtual Apps and Desktops Site specifies that it will be created with 1 Site and different zones in each of 3 regions. The IT team expects that each zone will host 825 concurrent user sessions, with no more than 28 concurrent session launches.

What is the minimum acceptable Site-to-Site bandwidth required between the Primary Zone and a Satellite Zone?

A. 1 Kbps
B. 200 Mbps
C. 2 Mbps
D. 8 Gbps

Correct Answer:  C

Explanation:

This question is focused on understanding the minimum bandwidth requirements between the Primary Zone and a Satellite Zone in a Citrix Virtual Apps and Desktops deployment. Citrix provides well-documented bandwidth guidelines for communications between zones based on two key factors:

The number of concurrent sessions.
The number of concurrent session launches.

Key Citrix Best Practice References:

According to Citrix documentation:

Each concurrent user session launch requires approximately 1.5 Mbps of bandwidth from the Satellite Zone to the Primary Zone for duration of 3–5 seconds during the launch phase.
However, steady-state traffic per active session (after launch) is negligible—about 1 Kbps or less per session, mainly for control traffic like monitoring and heartbeats.

So, bandwidth planning for zone-to-zone communication is primarily concerned with concurrent session launches, not the total number of active sessions.

Calculating Required Bandwidth

Given:

28 concurrent session launches per zone.

Using the Citrix recommendation of ~64 Kbps per concurrent launch (more accurate than the 1.5 Mbps earlier quoted for complete launch overhead):

28 concurrent launches×64 Kbps=1792 Kbps≈1.75 Mbps28 \text{ concurrent launches} \times 64 \text{ Kbps} = 1792 \text{ Kbps} \approx 1.75 \text{ Mbps}28 concurrent launches×64 Kbps=1792 Kbps≈1.75 Mbps

To ensure smooth operation and overhead buffering, Citrix recommends a minimum of 2 Mbps per Satellite Zone when up to 30 concurrent session launches are expected.

Why the Other Options Are Incorrect

A. 1 Kbps: This is far too low and only sufficient for control traffic per session in a steady state, not during launches.
B. 200 Mbps: This is excessive for only 28 concurrent launches; such bandwidth would typically be needed for data-intensive apps or thousands of launches.
D. 8 Gbps: Extremely excessive and unrealistic for 825 users and 28 launches; this might apply in datacenter-level replication or media-rich environments.

Based on Citrix’s design guidance and session launch traffic characteristics, the minimum bandwidth requirement for 28 concurrent session launches between a Satellite Zone and the Primary Zone is 2 Mbps.

Question 3

In a Citrix Virtual Apps and Desktops design, users in Chicago need to access printers located on a Citrix Universal Print Server in New York. The environment requires optimized bandwidth and performance, full availability, and auto-created default local printer functionality within HDX sessions. What specific configuration should the architect implement to meet the printing requirements for Chicago users?

A. Enable "Auto-create all client printers," set universal print driver usage to "Use universal printing only," apply to all users, install and configure the Universal Print Server, and set its policy to "Enabled with no fallback." Then create a session printer policy with the correct network printers for Chicago.
B. Enable "Auto-create all client printers," set universal print driver usage to "Use universal printing only," apply to Chicago users, install and configure the Universal Print Server, and set its policy to "Enabled with fallback." Then create a session printer policy for all users.
C. Enable "Auto-create client’s default printer only," set universal print driver usage to "Use universal printing only if requested driver is unavailable," apply to all users, install and configure the Universal Print Server, and set its policy to "Enabled with fallback." Then create a session printer policy for all users.
D. Enable "Auto-create client’s default printer only," set universal print driver usage to "Use universal printing only," apply to all users, install and configure the Universal Print Server, and set its policy to "Enabled with fallback." Then create a session printer policy for Chicago users.

Correct Answer:  D

Explanation:

Understanding the Scenario

The architect is tasked with setting up Citrix printing across three locations: Miami, New York, and Chicago. The key details from the scenario are:

The Citrix Site is located in Miami.
Users must use their default local printer within HDX sessions.
Chicago users require access to network printers located in New York (via a Citrix Universal Print Server).
Performance and bandwidth optimization are critical.
High availability is expected.
No manual configuration should be required on client devices.

Given this, the challenge is balancing auto-created default printers (for simplicity and user convenience) with Citrix Universal Print Server deployment (to access New York-hosted printers efficiently).

Breakdown of the Correct Configuration (Option D)

Auto-create client’s default printer only

This meets the requirement that “users will only need to access their default local print queue.”
It also limits unnecessary bandwidth consumption compared to auto-creating all client printers.

Universal print driver usage policy: Use universal printing only

This ensures consistent driver usage and helps with client compatibility without requiring additional configuration.
It aligns with the requirement that “auto-created client printer models must function with no additional configuration needed.”

Apply the policy to all users

Ensures a consistent policy experience across the environment and simplifies management.

Install and configure the Citrix Universal Print Server (UPS)

Required so that Chicago users can print to the New York-hosted printers.
This offloads print jobs from the VDA to the UPS, which reduces session bandwidth and increases reliability.

Configure UPS policy to: Enabled with fallback to Windows native remote printing

The fallback ensures high availability, which is a stated requirement.
If the UPS becomes unavailable, Windows native remote printing will still allow printing.

Create session printer policy for users in Chicago

This targets the Chicago user base specifically, meeting their unique requirement of accessing New York network printers.
It ensures that the correct printers are mapped only for the necessary users, optimizing bandwidth.

Why Other Options Are Incorrect

Option A uses "Auto-create all client printers" and disables fallback for UPS. This causes unnecessary printer creation (wasting bandwidth) and no failover if the UPS fails.
Option B applies the session printer policy to all users, which is unnecessary and may burden non-Chicago users with irrelevant printer mappings.
Option C enables fallback but sets the universal print driver policy too leniently (“only if requested driver is unavailable”), which may lead to unpredictable driver behavior and violate the “no configuration” requirement.

Option D provides the best configuration to satisfy all requirements:

It optimizes bandwidth.
It auto-creates only the default local printer.
It ensures high availability via fallback.
It meets printing needs for Chicago users accessing New York printers.

Question 4

Based on the Citrix Virtual Apps and Desktops site design shown in the diagram, what will occur if all Delivery Controllers located in the Primary Zone become unavailable? How will the Virtual Delivery Agents (VDAs) in the Primary Zone behave regarding registration?

A. Satellite Zone 2 will be promoted and the Primary Zone Virtual Delivery Agent (VDA) machines will register within Satellite Zone 2.
B. Virtual Delivery Agent (VDA) machines in the Primary Zone will NOT register within Satellite Zone 1 or Satellite Zone 2.
C. Virtual Delivery Agent (VDA) machines in the Primary Zone will register within Satellite Zone 2.
D. Virtual Delivery Agent (VDA) machines in the Primary Zone will register within Satellite Zone 1.

Correct Answer:  B

Explanation:

Understanding the Zone Configuration

In a Citrix Virtual Apps and Desktops environment, zones are used to manage geographical distribution of infrastructure components while maintaining centralized control. Each zone contains its own set of Delivery Controllers, and VDAs are designed to register with Controllers within their local zone first. If those are unavailable, failover registration can occur—but only if explicitly configured.

The diagram provided shows three zones:

Primary Zone: This is the main site with StoreFront, License Server, Studio, Director, Site Database, and two Controllers.
Satellite Zone 1: Contains its own Controller and StoreFront.
Satellite Zone 2: Also contains its own Controller, StoreFront, and VDA.

The question involves all Delivery Controllers in the Primary Zone failing.

How VDA Registration Works

By default, VDAs register only with Controllers within their own zone. Failover to Controllers in another zone is possible only if zone preference and VDA registration failover have been configured via policy.

In the diagram, there is no indication of failover or zone preference policy being set.
Since the VDAs in the Primary Zone do not have available Controllers, and without an explicit failover policy to Satellite Zones, the VDAs in the Primary Zone cannot register.

Why the Other Options Are Incorrect

Option A: Citrix does not “promote” Satellite Zones automatically. There is no such automatic promotion behavior when a zone fails. Failover must be manually configured.
Option C and D: These assume that the Primary Zone VDAs will register with another zone’s Controllers. Again, this requires failover configuration, which is not shown in the scenario. Without it, VDAs will not register outside their zone.

Key Concepts

Zone-local registration is the default behavior.
Failover registration is not automatic and must be explicitly configured.
Without Controllers, VDAs cannot register or broker sessions.
Database proximity and site architecture do not override VDA zone affinity rules.

Given no information in the scenario about a configured failover registration policy, and with all Primary Zone Controllers failing, the Primary Zone VDAs will not register with Controllers in Satellite Zone 1 or 2.

Question 5

A Citrix Architect is setting up a new Citrix Virtual Apps and Desktops environment and identifies a need to support legacy USB printers that require local and session-based access. Since HDX-optimized printing won’t work with these devices, the architect plans to use Generic USB redirection.

Which two considerations are important when using this method?

A. It requires more network bandwidth compared to standard HDX virtual channels.
B. Local access to printers will be lost until the HDX session is disconnected or ended.
C. Manufacturer printer drivers will need to be installed on user workstations.
D. The Citrix Virtual Channel Software Development Kit (VCSDK) will be required.
E. It is supported for only USB 3.0 devices and features.

Correct Answers: A and B

Explanation:

Understanding Generic USB Redirection in Citrix

Generic USB redirection allows entire USB devices (such as legacy printers) to be passed directly from the local endpoint to the virtual session over the ICA/HDX connection. This is useful when optimized redirection (e.g., HDX USB printing) doesn’t support a device. However, it comes with performance, compatibility, and user experience trade-offs.

Why Option A is Correct:

Generic USB redirection encapsulates full USB protocol data over the ICA session. This means it often transmits more data compared to other optimized virtual channels, like the HDX Print virtual channel, which compresses and sends only print jobs. As a result, it consumes significantly more bandwidth and can be sensitive to latency.

This makes Option A correct — it requires more network bandwidth compared to optimized HDX channels.

Why Option B is Correct:

When a USB device is redirected using Generic USB redirection, it is exclusively controlled by the virtual session. The local operating system on the user’s endpoint can no longer access the device until the session ends or the device is released from the session.

This behavior applies to redirected printers too — if redirected into the HDX session, they are not accessible locally until the session is disconnected or ends.

Thus, Option B is also correct.

Why the Other Options Are Incorrect:

Option C: The manufacturer’s driver needs to be installed on the VDA (virtual desktop or session host) — not on the user’s workstation. The client machine doesn’t need the driver; the redirection sends raw USB commands to the server side.
Option D: The VCSDK is used by developers to build custom virtual channels. It is not required to use existing features like Generic USB redirection. This is unnecessary in standard deployments.
Option E: Generic USB redirection supports a wide range of USB device types and versions, including USB 1.1 and USB 2.0, not just USB 3.0. Therefore, saying it supports “only USB 3.0” is incorrect.

The Citrix Architect must be aware that Generic USB redirection:

Consumes more network bandwidth, and
Prevents local device access during redirection.

Question 6

In a Citrix Virtual Apps and Desktops environment designed with an active-passive architecture, if the Delivery Controllers in the primary (active) data center fail.

What outcome should be expected given the design includes GSLB, Local Host Cache, StoreFront in both data centers, and VDAs registered per zone?

A. VDA machines from the primary data center would register with the Delivery Controllers in the passive data center.
B. StoreFront in the primary data center would still be able to launch sessions.
C. GSLB will start redirecting connections to the secondary data center.
D. GSLB will NOT identify that the Delivery Controllers are down and sessions CANNOT launch.

Correct Answer:  C

Explanation:

Understanding the Active-Passive Setup and GSLB Role

This Citrix deployment utilizes Global Server Load Balancing (GSLB) to route users to the active data center, which is the primary zone. When the primary Delivery Controllers fail, it is critical to understand the failover behavior of GSLB and how the architecture components respond:

GSLB is configured with health monitors, which means it can detect the failure of services, such as Delivery Controllers or StoreFront servers.
When failure is detected, GSLB can redirect user traffic to the passive data center (disaster recovery zone), where an alternate set of StoreFront servers and Delivery Controllers are deployed.
StoreFront servers in each data center are configured to aggregate resources from Delivery Controllers in their respective zones, so when the primary site fails, users will be routed to the passive zone’s StoreFront and Delivery Controllers.
The Local Host Cache (LHC) ensures that site failure (e.g., SQL or controller outage) does not prevent session launches as long as at least one controller in the local zone is available.

Why Option C is Correct:

Option C states that GSLB will start redirecting connections to the secondary data center. Since GSLB is equipped with health monitors, it detects that the Delivery Controllers in the primary zone are down. As a result, it will reroute users to the passive zone, ensuring continuity.

This is precisely the expected behavior in a properly designed active-passive disaster recovery Citrix setup.

Why the Other Options Are Incorrect:

Option A: VDA machines in the primary zone are configured to register with their local zone’s Delivery Controllers. They will not automatically register with controllers in the passive zone unless explicitly configured to do so (which is not the case here). VDAs only fail over to another zone's controllers if zone preference and failover is configured.
Option B: If the Delivery Controllers in the primary zone are down, StoreFront in the primary data center will not be able to enumerate or launch sessions, as it depends on those controllers. So this is incorrect.
Option D: GSLB is configured with health monitors specifically to detect such failures. Therefore, it will detect that Delivery Controllers are down and will redirect — contradicting what this option claims.

Given the use of health monitors in GSLB and the presence of Delivery Controllers and StoreFront servers in the passive data center, GSLB will correctly redirect users to the secondary site when the primary site’s Delivery Controllers are offline.

Question 7

A Citrix Architect finds during assessment that a key business requirement is to disable automatic updates for the Citrix Workspace app, and all deployments must occur via electronic software distribution (ESD) only. When installing Citrix Workspace app for Windows via command line, which parameter should be used to meet this requirement?

A. /AutoUpdateStream=current
B. /AutoUpdateCheck=auto
C. /AutoUpdateStream=disabled
D. /AutoUpdateCheck=disabled

Correct Answer:  D

Explanation:

Citrix Workspace App Installation and Update Control

In many enterprise environments, administrators must maintain tight control over software versions to ensure compatibility, regulatory compliance, and test cycle stability. Therefore, automatic update functionality must be disabled, and all updates are done through centralized software distribution tools (such as SCCM or Intune). Citrix supports this by providing installation parameters to control update behavior.

Understanding the Update-Related Installation Parameters

When installing Citrix Workspace app for Windows via command line, the following two parameters are commonly used to control update settings:

/AutoUpdateCheck: This parameter enables or disables the automatic update check feature.

Valid values: auto, disabled
auto: Enables automatic update checks (default behavior)
disabled: Disables automatic update checks (required in this scenario)

/AutoUpdateStream: This parameter defines which update stream the Workspace app subscribes to — either current or ltsr (Long-Term Service Release). However, this stream still requires that updates be enabled.

In this scenario, since automatic updates must be fully disabled, the only correct parameter to use is /AutoUpdateCheck=disabled.

Why Option D is Correct:

Option D sets /AutoUpdateCheck=disabled, which tells the Citrix Workspace installer not to check for or apply updates automatically. This aligns perfectly with the business requirement to disable automatic updates and handle software deployment only via ESD. Therefore, this is the correct answer.

Why the Other Options Are Incorrect:

Option A (/AutoUpdateStream=current): This only sets the update stream to "current" but does not disable update checks or downloads. Updates will still happen automatically unless otherwise disabled.
Option B (/AutoUpdateCheck=auto): This enables automatic updates, which is the opposite of the requirement.
Option C (/AutoUpdateStream=disabled): This is an invalid value. The /AutoUpdateStream parameter only accepts values like current or ltsr, not disabled. Using an invalid value may result in errors or be ignored during installation.

Question 8

A Citrix Architect is designing a small production environment that will be hosted in a single data center. The environment must allow for maintenance without requiring an outage, and management effort must be kept low.

Based on these criteria, what hardware configuration should be used for the Citrix Hypervisor hosts?

A. N+1 Citrix Hypervisor hosts in a single cluster/pool
B. Separate Citrix Hypervisor cluster/pool in an alternate data center
C. Multiple individual Citrix Hypervisor hosts in the same data center
D. Separate Citrix Hypervisor clusters/pools in the same data center

Correct Answer:  A

Explanation:

Key Requirements Analysis

From the scenario, we can identify three main requirements:

Single data center deployment – This rules out any design that requires multiple or remote data centers.
Maintenance without outages – The environment must have enough redundancy to ensure continuous availability during host maintenance.
Minimal management effort – The design should be simple to maintain and manage.

Let’s evaluate how each of the options meets (or fails to meet) these needs.

Why Option A is Correct: N+1 Citrix Hypervisor Hosts in a Single Cluster/Pool

The N+1 model means that one additional host is added beyond the minimum needed to support the production load (N). This additional host allows high availability and planned maintenance. If one host fails or needs maintenance, its workloads can be moved to the extra host without downtime.

When these hosts are in a single cluster/pool, they can share storage and networking resources, enabling seamless workload migration (e.g., using XenMotion). This setup is centralized and easy to manage, fulfilling the low-management requirement.

Therefore, Option A fully meets all criteria:

Single data center – Yes
Maintenance without outage – Yes (N+1 redundancy)
Low management – Yes (single pool/cluster with shared resources)

Why the Other Options Are Incorrect

Option B: Separate cluster/pool in an alternate data center
Violates the single data center requirement. It adds unnecessary complexity and cost for a small production environment.
Option C: Multiple individual Citrix Hypervisor hosts in the same data center
This setup lacks resource pooling and high availability. Maintenance would require powering off workloads or users experiencing downtime. Management overhead would be higher due to isolated configurations per host.
Option D: Separate Citrix Hypervisor clusters/pools in the same data center
Although still in a single data center, managing multiple clusters/pools increases complexity, violating the “minimal management” requirement. It also complicates resource balancing and VM migration.

Question 9

A Citrix Architect is setting up a new Citrix Virtual Apps and Desktops environment with 1,000 Advanced licenses. The company needs the IT team to generate reports of all unsuccessful Citrix Virtual Apps connections over the past 12 months.

What two steps must the architect take to meet these requirements?

A. Configure ‘GroomSessionsRetentionDays’ to 365 days
B. Upgrade to Citrix Virtual Desktops Premium licenses
C. Configure ‘GroomFailuresRetentionDays’ to 365 days
D. Upgrade to Citrix Gateway Universal licenses
E. Implement Citrix Application Delivery Management

Correct Answers: B and C

Explanation:

Understanding the Scenario and Requirements

The primary requirement is the ability to report on all unsuccessful connection attempts to Citrix Virtual Apps over a 12-month period. This falls under monitoring and historical analytics, which require:

Retention of failure data (for 365 days)
Licensing features that support extended historical analytics

Let’s analyze what is needed and why.

Citrix Director and Licensing Tiers

Citrix Director is used for monitoring and reporting in Citrix environments.
Advanced licenses only support basic historical data, typically up to 7 days.
To access extended retention and advanced monitoring (up to a year), Citrix Virtual Apps and Desktops Premium edition is required.
Additionally, failure events (like login failures, connection issues, etc.) are retained using the GroomFailuresRetentionDays setting in the monitoring database. But this setting can only take effect if the licensing tier allows long-term data retention (i.e., Premium edition).

Why Option B is Correct: Upgrade to Premium Licenses

To enable long-term historical reporting (365 days), the architect must upgrade from Advanced to Premium licensing. Advanced licensing does not support extended analytics or Director’s full retention capabilities.

Without Premium, even if the database settings are configured, the data won’t be retained or accessible.

Why Option C is Correct: Configure ‘GroomFailuresRetentionDays’

This database parameter sets how long to retain failure logs—which include unsuccessful connection attempts. To support a 12-month (365 days) reporting window for connection failures, this setting must be manually updated in the Citrix monitoring database.

Note: This setting must be configured in tandem with Premium licensing; otherwise, it won’t have the intended effect.

Why the Other Options Are Incorrect

Option A (GroomSessionsRetentionDays): This affects session data, not failures. The question specifically asks for unsuccessful connections, not session activity.
Option D (Citrix Gateway Universal licenses): These relate to access through Citrix Gateway but have no impact on Director data retention or failure logging.
Option E (Citrix Application Delivery Management): ADM is used for managing and monitoring network appliances, not Citrix Virtual Apps session and connection failures. It’s not related to Citrix Director's retention or analytics of app sessions.

To meet the requirement of producing 12-month reports on unsuccessful Citrix Virtual Apps connections, the architect must both enable the appropriate data retention configuration and upgrade to the required license tier.

Question 10

A Citrix Architect is designing a Virtual Desktops environment for the Engineer Group, which requires NVIDIA GPU virtualization (vGPU) to support graphical applications. The proposed setup includes NVIDIA GRID Tesla P40, Microsoft Hyper-V Server 2012 R2, Windows 10 VMs, and Citrix Virtual Desktops 7.

Which component must be changed to support shared GPU (vGPU) functionality?

A. Windows 10 virtual machines
B. Citrix Virtual Desktops 7
C. NVIDIA GRID Tesla P40 GPUs
D. Microsoft Hyper-V Server 2012 R2

Correct Answer:  D

Explanation:

Understanding the Use Case

The scenario centers around supporting virtualized GPU (vGPU) functionality for high-performance graphical workloads. The Engineer Group will use NVIDIA GRID hardware (Tesla P40) to provide this support through vGPU technology—which allows multiple virtual machines to share a single physical GPU. This is often used in VDI environments to offload graphics-intensive processing from the CPU to the GPU.

To implement this, all components in the virtualization stack must support NVIDIA vGPU technology, including:

The GPU hardware
The hypervisor
The virtual machine OS
The Citrix software stack

Let’s examine each component’s compatibility.

Component Analysis

NVIDIA GRID Tesla P40 GPUs
These are vGPU-compatible hardware units explicitly designed to support GPU sharing. Tesla P40 is part of NVIDIA’s Tesla series used in virtualized environments with vGPU support.
This component is compatible and does not need to be changed.
Windows 10 Virtual Machines
Windows 10 is fully supported as a guest OS for vGPU workloads. It is frequently used with Citrix Virtual Desktops and NVIDIA vGPU solutions.
No change needed here.
Citrix Virtual Desktops 7
Citrix Virtual Desktops (formerly XenDesktop) supports GPU passthrough and vGPU configurations. While older versions might lack some newer feature enhancements, Citrix Virtual Desktops 7 is fundamentally compatible with vGPU when paired with supported hardware and hypervisors.
This component does not need to be changed.
Microsoft Hyper-V Server 2012 R2
This is the critical issue. Microsoft Hyper-V 2012 R2 does not support NVIDIA vGPU. While it does support basic GPU passthrough (Discrete Device Assignment in newer versions), true vGPU functionality with NVIDIA GRID technology is not supported in this version of Hyper-V.
vGPU technology is typically supported on:

VMware vSphere (ESXi)
Citrix Hypervisor (formerly XenServer)
More recent versions of Hyper-V (starting with Windows Server 2016+ under limited circumstances)

Hyper-V 2012 R2 must be replaced with a hypervisor that supports NVIDIA vGPU.

To meet the vGPU requirement with NVIDIA GRID Tesla P40 in a Citrix Virtual Desktops environment, the architect must replace Microsoft Hyper-V Server 2012 R2 with a supported hypervisor such as Citrix Hypervisor or VMware ESXi.
