2V0-51.23 VMware Practice Test Questions and Exam Dumps

Question 1

An organization needs a VMware Horizon deployment that enables fast deployment of Windows and Linux desktops, centralized brokering, and end-to-end security.

Which solution best meets all of these requirements?

A. VMware vSphere Desktop Edition
B. VMware Horizon On-Premises
C. VMware Horizon Cloud on Microsoft Azure
D. VMware Workspace ONE Unified Endpoint Management

Correct Answer: C

Explanation:
This question focuses on selecting the correct VMware Horizon deployment model based on specific organizational requirements: rapid deployment of desktops (Windows and Linux), centralized brokering, and a secure, end-to-end environment.

Let’s evaluate each of the provided options based on these three key requirements.

Requirement 1: Fast deployment of Windows and Linux desktops
This suggests the organization wants the ability to quickly provision virtual desktops across various operating systems. Ideally, this would be done in a scalable cloud environment without the delays of infrastructure procurement or data center setup. VMware Horizon Cloud on Microsoft Azure supports provisioning both Windows and Linux desktops quickly through Azure’s cloud-native services and VMware’s automated provisioning tools.

Requirement 2: Centralized brokering
A broker in a virtual desktop environment authenticates and connects users to the appropriate virtual desktop or app. VMware Horizon Cloud offers a cloud-based brokering service that allows centralized control, session assignment, and policy enforcement—regardless of where the desktops reside. This centralized brokering is a core feature of Horizon Cloud on Azure, which provides consistent access across distributed desktops with a unified management plane.

Requirement 3: End-to-end security
Security is a foundational part of VMware Horizon Cloud on Azure. It leverages both VMware and Azure security features including multi-factor authentication, zero trust access policies, encryption of data in transit and at rest, and integration with Microsoft Defender for Endpoint. In addition, Horizon Cloud minimizes the attack surface by eliminating the need to expose desktops directly to the public internet—traffic flows through secure gateways.

Now, let’s evaluate the answer choices:

A. VMware vSphere Desktop Edition
This is a licensing SKU, not a deployment model. It enables running virtual desktops on vSphere but does not, by itself, include desktop brokering or security controls. It also lacks the integrated cloud features required for fast provisioning and management. Therefore, it does not meet the criteria.

B. VMware Horizon On-Premises
While capable of providing secure desktop access and centralized brokering, on-premises deployments typically require significant time to implement due to hardware procurement, setup, and integration. This option may not support rapid deployment as efficiently as a cloud-based model.

C. VMware Horizon Cloud on Microsoft Azure
This solution is designed specifically for fast, scalable desktop provisioning in the cloud. It includes a cloud-based broker, seamless integration with Azure infrastructure, and a secure architecture that leverages both VMware and Microsoft’s enterprise-grade protections. This option meets all three of the requirements directly and efficiently.

D. VMware Workspace ONE Unified Endpoint Management
Workspace ONE is primarily an endpoint management platform. While it integrates with Horizon and can be used to manage physical and virtual devices, it is not a desktop virtualization solution. It does not include brokering capabilities or the infrastructure needed to host desktops. Therefore, it does not meet the requirements independently.

Considering the organization's needs—rapid deployment, centralized brokering, and end-to-end security—VMware Horizon Cloud on Microsoft Azure is the only solution that aligns directly and fully with all three. It enables fast provisioning, includes a built-in broker, and provides strong integration with security policies.

Question 2

Adobe Acrobat 11 is assigned to a user through App Volumes. VM25 already has Adobe Acrobat 11 installed natively. What occurs when the user logs into VM25?

A. The user-assigned application is attached to VM25. When the user clicks on the application shortcut, the App Volume package for Adobe Acrobat 11 is opened.
B. Although a shortcut to the App Volume package is created on the user desktop, the application does not get attached to VM25.
C. The App Volume package does not get attached because the natively installed application has priority.
D. A shortcut to the user-assigned application is created on the user desktop, and when they click on the shortcut, the application gets attached to VM25.

Correct Answer : C

Explanation:

When using VMware App Volumes, the core concept is to attach application packages dynamically to desktops or users, so they appear natively installed without having to actually install them on every virtual machine. However, App Volumes is designed with awareness of conflicts between natively installed applications and AppStack-delivered applications. This is crucial in environments where the same application may exist in both forms.

In this scenario, the application in question—Adobe Acrobat 11—is both assigned to the user through App Volumes and already natively installed on VM25. The behavior of App Volumes when such a conflict arises is guided by a rule: App Volumes does not attach an AppStack for an application that is already present on the machine natively. This is done to prevent DLL conflicts, version mismatches, registry collisions, and other problems that could arise when two versions of the same application attempt to coexist on the same system.

Let’s analyze the options in this context:

Option A suggests the App Volume package is attached and used when the user launches the application. This is incorrect because App Volumes will not attach a package if the application is already natively installed.

Option B says a shortcut is created but the application isn’t attached. This would only be partially true in certain delayed-attachment configurations, but in standard App Volumes operations, AppStacks are attached at login. If the native app is detected, the AppStack for the same application is not attached at all—so even the shortcut would not appear unless explicitly published, which would create confusion and potentially break the user experience.

Option C correctly states that the App Volume package does not get attached because the native application takes precedence. This reflects actual App Volumes behavior. The system is designed to defer to the installed version of an application if one exists, both to avoid conflict and to preserve functionality.

Option D implies that a shortcut is created and triggers the AppStack attachment on click. However, AppStacks are not attached on-demand in this way. They are mounted either at user login or when the machine starts, depending on the type of assignment (machine-based or user-based). App Volumes doesn’t support lazy or triggered attachment of packages upon clicking a shortcut.

Therefore, based on VMware App Volumes’ conflict-avoidance mechanism and standard behavior, the correct interpretation is that no AppStack is attached when the same application is already installed natively.

Thus, the correct answer is C.

Question 3

A VMware Horizon administrator is tasked with deploying a desktop pool that meets the following criteria: users should always receive the same virtual desktop machine, compatibility with an existing image-based backup solution is required, and the desktops will be cloned weekly using the vSphere API.

Which desktop pool type best meets these requirements?

A. Automated Desktop Pool, based on Dedicated Full Clone Virtual Machines
B. Automated Desktop Pool, based on floating Instant Clones
C. Automated Desktop Pool, based on dedicated Instant Clones
D. Automated Desktop Pool, based on Floating Full Clone Virtual Machines

Correct Answer : A

Explanation:

To determine the best solution for this scenario, we must evaluate each requirement and analyze how the different VMware Horizon desktop pool types meet or fail to meet them. The key requirements are:

Users should always get the same desktop VM – This implies a dedicated assignment, meaning each user is tied to a specific virtual desktop.
Image-based backup compatibility – The existing backup solution relies on image-level backups via vSphere. This restricts us to using Full Clones, because Instant Clones and Linked Clones do not work well with traditional image-based backup tools due to their dynamic and ephemeral nature.
Cloning weekly via vSphere API – This again implies administrative control over cloning and maintenance, suggesting the need for desktops that persist over time and aren't automatically destroyed or refreshed.

Now let’s evaluate each of the answer choices:

A. Automated Desktop Pool, based on Dedicated Full Clone Virtual Machines
This option fits all the requirements:

Dedicated: Each user is assigned a specific virtual desktop that remains theirs.
Full Clones: Fully independent VMs that are compatible with image-level backup tools.
Automated: Can be managed and provisioned through vSphere and VMware Horizon; cloning via API is fully supported.

B. Automated Desktop Pool, based on floating Instant Clones
This is incorrect because:

Floating: Users receive a random available desktop, not the same one every time.
Instant Clones: These are not persistent and are recreated frequently, making them incompatible with traditional backup solutions.

C. Automated Desktop Pool, based on dedicated Instant Clones
While dedicated, this solution uses Instant Clones, which:

Are ephemeral and are refreshed often.
Do not persist in a way that supports standard image-based backups.
Thus, this fails the backup requirement.

D. Automated Desktop Pool, based on Floating Full Clone Virtual Machines
This is incorrect because:

Floating means the user is not assigned to the same VM consistently.
Though Full Clones support backup, the lack of a dedicated assignment disqualifies this option for the user experience requirement.

Only option A provides persistent, backup-compatible desktops that satisfy both the user assignment and technical management needs such as cloning and backup. It provides a stable desktop for each user and integrates well with vSphere operations and traditional backup workflows.

Therefore, the correct answer is A.

Question 4

An organization needs to prevent specific users from saving any data from their virtual desktops to their client devices during non-business hours (5PM to 9AM). Which method should be used to enforce this policy?

A. Import vdm_blast.admx template to Active Directory and setup a new Group Policy Object with required settings.
B. Configure corporate firewall to block port TCP 9427 from 5PM till 9AM.
C. Set the configuration in HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Agent\ on virtual desktops.
D. Use settings in Dynamic Environment Manager Horizon Smart Policy and set Conditions.

Correct Answer: D

Explanation:
This question involves enforcing time-based access control policies that affect user interactions with virtual desktops—in particular, restricting data redirection to client devices outside of business hours. The goal is to prevent data exfiltration or unsanctioned data transfer during off-hours.

To solve this, we need a context-aware policy that can:

Apply based on user identity or group membership.
Evaluate the time of day or day of the week.
Dynamically enforce data redirection policies like blocking clipboard access, drive mapping, and USB redirection.

Only one option among the choices supports such conditional and granular enforcement: VMware Dynamic Environment Manager (DEM) Horizon Smart Policies.

Let’s go through the options to see why:

A. Import vdm_blast.admx template to Active Directory and setup a new Group Policy Object with required settings.
This method allows administrators to configure Group Policy settings related to the Blast Extreme protocol, which includes bandwidth, quality, and session handling controls. However, GPOs are not dynamic by default—they are static and apply on refresh (typically during login or at intervals). They don’t allow time-of-day-based conditional enforcement unless combined with scripts or advanced GPO configurations. Also, GPOs are not user-specific in the same flexible way that DEM can be.

B. Configure corporate firewall to block port TCP 9427 from 5PM till 9AM.
Port 9427 is not specifically relevant to VMware Horizon client redirection capabilities. Even if a relevant port were blocked, this method would be too coarse and would affect all users, not just targeted ones. Firewalls lack the application-layer intelligence needed to block specific data redirection features within a Horizon session or distinguish between users and time conditions within the session.

C. Set the configuration in HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Agent\ on virtual desktops.
This registry path is indeed used for many Horizon agent configurations. However, registry settings are static and typically do not support conditional enforcement based on time or user group. They would also require scripting or policy refreshes and would lack flexibility and central management, especially across many virtual desktops.

D. Use settings in Dynamic Environment Manager Horizon Smart Policy and set Conditions.
This is the correct and most powerful method. Dynamic Environment Manager (DEM), when integrated with Horizon Smart Policies, provides context-aware control over user session behaviors. Smart Policies allow administrators to define conditions such as:

Time of day (e.g., between 5PM and 9AM),
User group membership,
Client device type,
IP address or location.

You can then apply policy actions such as disabling:

Drive redirection,
Clipboard redirection,
USB device usage,
Printing,
And more.

This enables fine-grained, real-time control without the need to log out or refresh the session. The settings can be centrally managed and updated, and they apply dynamically as users connect or reconnect.

Only Dynamic Environment Manager with Horizon Smart Policies can meet all three core requirements: dynamic enforcement, time-of-day awareness, and user-specific control over data redirection. It is purpose-built for this exact type of scenario in VMware Horizon environments.

Question 5

An administrator deployed a Horizon pod with external access using Unified Access Gateway (UAG). External users experience a black screen followed by disconnection when launching VDI, even though required ports are open. Internal users connect successfully. UAG logs show Blast traffic going to the Connection Server instead of the VDI machine.

What action should the administrator take to fix the issue?

A. Upload the Blast Proxy Certificate in Horizon Edge Settings.
B. Update the Blast External URL in UAG with port number.
C. Enable Tunnel in UAG.
D. Disable the Tunnel and Gateways in Horizon Connection Server.

Correct Answer : D

Explanation:

The described scenario is a classic example of a misconfiguration in a VMware Horizon environment where Unified Access Gateway (UAG) is used to facilitate external access. Here’s the breakdown of the symptoms and reasoning leading to the correct solution:

Problem Description:

External users attempt to access VDI through the UAG.
The connection begins but results in a black screen followed by disconnection.
Internal access through the Connection Server URL works fine.
All required ports are open.
UAG logs reveal that Blast traffic is being routed to the Connection Server instead of the VDI host.

This behavior indicates that the Blast traffic, which should be routed directly from the UAG to the target VDI machine, is instead being incorrectly routed through the Connection Server. This happens when the Horizon Connection Server is configured to tunnel protocol traffic, which is not the correct configuration when UAG is in use.

Why This Happens:

In Horizon, when a UAG is used, the traffic flow should look like this:

External client → UAG → VDI machine (Blast or PCoIP)
Not: External client → UAG → Connection Server → VDI machine

If the "Use Secure Tunnel connection to desktop" or "Use Blast Secure Gateway" options are enabled on the Connection Server, protocol traffic is incorrectly routed back through the Connection Server, which is not accessible externally. This causes traffic to fail (black screen and disconnect) because the Connection Server cannot broker protocol-level connections across external networks.

Correct Solution:

The administrator must disable the Tunnel and Gateways in the Horizon Connection Server settings. This ensures that UAG alone is responsible for managing and proxying protocol traffic, and it allows the client to directly establish a session with the VDI machine via UAG—which is the recommended architecture.

To do this:

Log into the Horizon Administrator Console.
Go to View Configuration > Servers > Connection Servers.
Edit the affected Connection Server.
Under General, make sure the following are unchecked:

"Use Secure Tunnel connection to desktop"
"Use PCoIP Secure Gateway"
"Use Blast Secure Gateway"

These settings must be disabled when using UAG so that the UAG handles these protocols, not the Connection Server.

Why the Other Options Are Incorrect:

A. Uploading a certificate in the Blast Proxy settings is good practice for encryption and trust but does not address routing misconfiguration or protocol traffic flow.
B. Updating the Blast External URL in UAG might be necessary if it's missing or incorrect, but in this case, traffic is not even reaching the correct endpoint due to Connection Server settings.
C. Enabling Tunnel in UAG is unrelated to this issue. UAG acts as the gateway; the tunnel setting applies in limited use cases and isn’t a fix for protocol misrouting.

Thus, the action required is to correct the traffic flow by disabling the Tunnel and Gateway settings on the Horizon Connection Server, allowing UAG to serve its role as the protocol gateway for external users.

The correct answer is D.

Question 6

A junior Horizon administrator reports being unable to view all RDS (Remote Desktop Services) farms in the environment.

Where should a higher-level administrator make changes to resolve this visibility issue?

A. Global Entitlements
B. Access Groups
C. Global Policies
D. Category Folder

Answer: B

Explanation:

To determine the correct answer, it is essential to understand what could restrict a junior-level Horizon administrator’s ability to view specific RDS farms. In VMware Horizon, administrative visibility and control are governed by role-based access control (RBAC) and access group assignments.

Here is a breakdown of what each option refers to and why Access Groups is the correct answer:

A. Global Entitlements
Global Entitlements are used in Cloud Pod Architecture (CPA) configurations, where multiple Horizon pods are connected across sites or data centers. Global Entitlements allow users to access desktops or applications regardless of which pod they’re assigned to. However, Global Entitlements affect end-user access, not administrator visibility or access to RDS farms. Therefore, this setting does not influence what a junior admin can see in the Horizon Console.

B. Access Groups
Access Groups in VMware Horizon are used to organize and segment desktop pools, RDS farms, and application pools. More importantly, administrative privileges can be scoped to specific Access Groups. This means a junior-level admin may be assigned a role that allows visibility only within certain Access Groups. If the RDS farms in question are located in Access Groups outside the scope of the junior admin's permissions, they will not be visible to that admin. To correct this, a higher-level administrator needs to either:

Grant the junior admin rights to additional Access Groups, or
Move the RDS farms into an Access Group the junior admin already has access to, depending on the organizational policy.

This directly controls the visibility and manageability of RDS farms and other Horizon objects, making it the correct place to fix the problem.

C. Global Policies
Global Policies in Horizon define system-wide behavior such as USB redirection, clipboard redirection, and session timeouts. These are applied to end-user sessions, not administrative visibility. Adjusting Global Policies will not resolve an issue where an admin cannot view certain objects in the Horizon Console.

D. Category Folder
Category Folders are used for organizing published applications for end-user presentation, especially within VMware Workspace ONE or Horizon Client. They are irrelevant to administrator visibility or permissions. Changes here would not affect what a junior admin can or cannot see in terms of infrastructure components like RDS farms.

The visibility of RDS farms for Horizon administrators is determined by their assigned permissions and the Access Groups in which those RDS farms reside. Since Access Groups are the mechanism by which administrators' visibility is controlled, the correct action is for a higher-level admin to modify the junior admin's access permissions to include the relevant Access Groups.

Therefore, the correct answer is B.

Question 7

Which two client types typically offer the lowest total cost of ownership (TCO) and make it easier to manage deployments, handle firmware updates, and monitor performance?

A. Headless Clients
B. Windows Clients
C. Thin Clients
D. Zero Clients
E. MacOS Clients

Correct Answers: C, D

Explanation:
This question is about identifying which client types are the most cost-effective and simplest to manage when deploying virtual desktop infrastructure (VDI), such as VMware Horizon.

When organizations evaluate VDI client devices, they typically look at the total cost of ownership (TCO), which includes not only the upfront device cost but also ongoing costs such as maintenance, software updates, manageability, and support. Two types of clients stand out in this space for low TCO and ease of centralized management: Thin Clients and Zero Clients.

Let’s evaluate each option based on these criteria.

A. Headless Clients
Headless clients generally refer to devices without monitors—used in server farms or embedded systems. These are not standard in VDI environments for end-user access. They might be cost-effective in specific technical use cases, but they are not standard VDI endpoints and therefore not relevant in this context. They also don’t offer built-in manageability or monitoring features for VDI workflows.

B. Windows Clients
While Windows-based clients are highly flexible, they have higher TCO for several reasons:

Regular Windows updates (feature and security),
Required antivirus/antimalware software,
Greater support needs,
Potential licensing costs,
Need for local software management.
They also introduce more management overhead because they behave like full desktops and require patching and maintenance, which can increase both IT effort and risk. Therefore, Windows clients are not considered low-cost or easy to manage in VDI scenarios.

C. Thin Clients
Thin Clients are lightweight computing devices that connect to a VDI session and rely on centralized computing resources. They:

Run a minimal operating system (often Linux-based),
Are purpose-built for remote display protocols like PCoIP or Blast Extreme,
Support centralized management tools for firmware updates and configuration,
Often come with vendor-specific software (e.g., Dell Wyse Management Suite, HP Device Manager) to manage large fleets easily.
Because of their low power usage, minimal software footprint, and centralized administration, thin clients offer low TCO and simplified deployment. They are well-suited for environments looking to scale with minimal IT overhead.

D. Zero Clients
Zero Clients are even more streamlined than thin clients. They have:

No local OS (or an extremely minimal one),
No local storage,
Exclusive support for a specific display protocol (e.g., PCoIP or Blast),
Centralized configuration pushed via management tools.
Because of this simplicity, zero clients have very low attack surfaces, require little-to-no maintenance, and are extremely easy to manage. Firmware updates are infrequent and often automated. They are ideal in highly secure, locked-down environments and deliver lowest TCO over time due to reduced management and support needs.

E. MacOS Clients
Apple macOS clients are general-purpose devices and typically have a higher TCO. They require regular macOS updates, have higher hardware costs, and do not offer the centralized management features needed in large-scale VDI deployments. While they may be used for connecting to VDI, they are not ideal for cost-efficient or easily managed enterprise deployments.

Conclusion:
The two client types that provide the lowest cost of ownership and the easiest management experience—including firmware updates and monitoring—are:

Thin Clients for their balance of simplicity, flexibility, and manageability.
Zero Clients for their extreme simplicity, security, and near-zero local maintenance.

Therefore, the correct answers are: C, D.

Question 8

Which two of the following are predefined Roles in Horizon Console? (Choose two.)

A. Desktop Pool Administrators
B. Instant Clone Administrators
C. Server Administrators
D. Local Administrators
E. Inventory Administrators

Correct Answer : A, E

Explanation:

In VMware Horizon, role-based access control (RBAC) is implemented via predefined roles in the Horizon Console. These roles define what a user can or cannot do within the Horizon environment. This allows administrators to delegate specific responsibilities to different users or groups without granting full administrative privileges to everyone.

VMware Horizon includes a set of predefined roles designed to support common use cases and to maintain a principle of least privilege approach. Each role grants access to specific areas and functions within the Horizon Console.

Let’s evaluate each of the provided options:

A. Desktop Pool Administrators

This is a predefined role in Horizon. The Desktop Pool Administrators role allows users to manage desktop pools, including creating, editing, and deleting desktop pools. However, this role does not grant access to broader system settings, servers, or global configurations. It is ideal for administrators responsible for managing desktop resources without full administrative access.

Correct.

B. Instant Clone Administrators

This is not a predefined role in the Horizon Console. While administrators can manage Instant Clones through other roles (such as the full Administrator role), "Instant Clone Administrators" is not one of the default roles listed in Horizon. This may sound plausible, but it is not an actual default role provided out of the box.

Incorrect.

C. Server Administrators

There is no predefined role called "Server Administrators" in Horizon. Server management in Horizon typically falls under broader administrative roles, such as Administrator or View Administrator, but this specific role does not exist in the role list.

Incorrect.

D. Local Administrators

This is not a Horizon Console role. While "Local Administrators" may refer to operating system-level administrative groups, it is not a role defined or used within the Horizon Console. Horizon roles are scoped to the Horizon management domain, not Windows local groups.

Incorrect.

E. Inventory Administrators

This is a predefined role in the Horizon Console. The Inventory Administrators role allows users to manage inventory-related objects in Horizon, such as desktop pools, farms, and assignments, without access to broader system configuration or administrative settings. This role is often used for help desk staff or inventory managers who need to oversee the Horizon deployment without full control.

Correct.

Summary of Predefined Roles in Horizon Console (Partial List):

Administrator: Full access to all features.
Inventory Administrator: Manages desktop pools, farms, and assignments.
Desktop Pool Administrator: Limited to managing desktop pools.
Help Desk Administrator: Designed for first-level support with read-only and troubleshooting access.
Read-Only Administrator: Can view settings but cannot make changes.

These roles provide flexibility and security by ensuring users only have access to the parts of the system they need to manage.

Therefore, the correct answers are A and E.
