VMware 2V0-51.23 VMware Horizon 8.x Professional Exam Practice Test

When configuring a virtual machine to use an NVIDIA graphics card, issues such as the VM not starting can occur if there is no suitable host available that meets the requirements for 3D graphics, or if not all memory required by the 3D graphics card has been reserved for the VM. Ensuring that the host has the necessary 3D graphics capabilities and that the VM is configured with reserved memory can resolve these issues.

The issue described indicates that the Horizon Connection Server is incorrectly handling traffic that should be directed to the Unified Access Gateway (UAG) and then to the VDI desktops. Disabling the Tunnel and Gateways settings on the Horizon Connection Server forces the UAG to handle the Blast traffic directly, ensuring that the connections are made to the VDI desktops' IP addresses, thus resolving the black screen and disconnection issue.

VMware Horizon Cloud on Microsoft Azure is the only deployment solution that meets all the requirements. VMware Horizon Cloud on Microsoft Azure supports Windows 10 Enterprise multi-session desktops, which are a new Remote Desktop Session Host exclusive to Azure Virtual Desktop on Azure1. It also supports App Volumes, which is a real-time application delivery system that enables IT to instantly provision applications to users or desktops. VMware Horizon Cloud on Microsoft Azure supports centralized brokering, which means that the Horizon Cloud Service acts as a single point of entry for end users to access their virtual desktops and applications. VMware Horizon Cloud on Microsoft Azure also supports automatic routing of end-users to the most appropriate virtual workspace, using the Universal Broker feature. Universal Broker is a cloud-based brokering service that provides a unified user experience across multiple Horizon pods and clouds.

VMware vSphere Desktop Edition does not support Windows 10 Enterprise multi-session desktops, as they are only available on Azure Virtual Desktop1. VMware Workspace ONE Unified Endpoint Management does not support App Volumes, as it is a different solution for managing devices and applications. VMware Horizon On-Premises does not support automatic routing of end-users to the most appropriate virtual workspace, as it requires manual configuration of load balancing and global entitlements. References:

VMware Horizon's Dynamic Environment Manager (DEM) allows for the creation of Horizon Smart Policies with conditions that can be applied based on various criteria, including time of day. By utilizing DEM, an administrator can create policies that restrict certain actions, such as saving data to client devices, outside of specified business hours (5PM to 9AM in this case), thus achieving the desired control over user activities based on the time of day.

Instant clones are a type of virtual machines that are created by cloning a running parent VM in memory, without requiring a full disk copy. This allows for faster provisioning and updating of RDS hosts in a farm. Instant clones can be patched in a rolling process with zero downtime by using the push-image operation, which replaces the existing instant clones with new ones that have the latest patches applied. The push-image operation can be performed on a per-farm basis or on multiple farms at once. The push-image operation preserves the user sessions and data on the existing instant clones until they are logged off or disconnected, and then deletes them. The new instant clones inherit the same settings and assignments as the old ones. Therefore, to deploy a RDS farm that can be patched in a rolling process with zero downtime, the administrator should create an instant-clone RDS desktop farm. References: Instant Clones for RDSH in VMware Horizon 7.1 and [VMware Horizon 8.x Professional Course]

VMware Horizon Agent for Linux is a software component that enables Linux machines to be used as remote desktops or published applications in a Horizon environment. Horizon Agent for Linux supports several features that enhance the user experience and manageability of Linux desktops and applications, such as USB redirection, display protocol PCoIP, multiple-session mode, single sign-on, smart card authentication, and 3D graphics34. However, Horizon Agent for Linux does not support location based printing or session collaboration features that are available for Windows machines5. Also, Horizon Agent for Linux does not require installation registration as it automatically registers with the Connection Server when the viewagent service is started6. References := 3: VMware Horizon 8 Documentation: Horizon Agent for Linux 4: VMware Horizon 8 Documentation: Features Supported by Horizon Agent for Linux 5: VMware Horizon 8 Documentation: Features Not Supported by Horizon Agent for Linux 6: VMware Horizon 8 Documentation: Install Horizon Agent on a Linux Machine

Global Entitlements in VMware Horizon allow for the aggregation of resources across multiple pods and sites into a single entitlement. This feature is particularly beneficial when publishing applications that are hosted across different pods, as it ensures that users see only one icon for the application, regardless of which pod it is hosted on, simplifying the user experience and administration of applications in a multi-pod Horizon environment.

Roles and permissions are a way of controlling the access and actions of administrators and users in Horizon. By default, Horizon provides two predefined roles: Administrators and Read Only Administrators. However, a high-level administrator can create custom roles with specific privileges to suit different needs and scenarios. To create a custom role, the administrator needs to follow these steps:

• In the navigation pane under the Settings section, click on Administrators > Roles and Permissions.
• In the Roles and Permissions page, click on Add.
• In the Add Role pane, enter a name for the role in the Role Name text box.
• In the Privileges section, select the checkboxes for the privileges that you want to assign to the role. You can expand or collapse the categories to view or hide the sub-privileges. You can also use the Select All or Deselect All buttons to select or clear all the privileges in a category.
• Click on Save to create the custom role.

The custom role will appear in the Roles and Permissions page, where you can edit or delete it as needed. You can also assign the custom role to users or groups in the Users and Groups page. References: [Create Custom Roles] and [VMware Horizon 8.x Professional Course]

One of the prerequisites for installing the Horizon Connection Server is to use a domain user account with administrator privileges on the system. This is because the installer needs to access and modify certain system files and registry settings, as well as create and configure the VMware Horizon View services. The installer also authorizes an Administrators account that has full administration rights for the Horizon environment, including the right to install replicated Connection Server instances. The other options are not prerequisites for installing the Horizon Connection Server. The host system can be a physical or virtual machine, but it must have an IP address that does not change. An SSL server certificate is not required for the initial installation, but it is recommended to replace the default self-signed certificate with a valid certificate from a trusted CA after the installation. AD DS and AD LDS Tools are not required for installing the Horizon Connection Server, but they can be useful for troubleshooting and managing the ADAM database that stores the Horizon configuration data. References: Installation Prerequisites for Horizon Connection Server and [VMware Horizon 8.x Professional Course]

Application Profiler is a tool that analyzes the registry and file system locations where the settings for a particular application are stored, and creates a Flex configuration file for use with Dynamic Environment Manager. Application Profiler is installed using VMware Dynamic Environment Manager Enterprise Setup Wizard and explicitly selecting local drive installation1. This option allows you to install Application Profiler on a separate machine from the Dynamic Environment Manager Agent or Management Console. Alternatively, you can install Application Profiler on the same machine as the Dynamic Environment Manager Agent or Management Console, by selecting network share installation1.

VMware Dynamic Environment Manager Agent and the Application Profiler can be installed on the same machine, but it is not recommended. This is because the Dynamic Environment Manager Agent might interfere with the profiling process by applying settings to the application being profiled1. Therefore, it is best to use a clean system for profiling applications.

Application Profiler is not installed automatically when installing VMware Dynamic Environment Manager FlexEngine or Management Console. FlexEngine is the component that applies the user environment settings during logon, logoff, and session reconnect or disconnect events2. Management Console is the component that allows you to configure and manage the user environment settings2. Neither of these components requires Application Profiler to function. Application Profiler is an optional tool that helps you create Flex configuration files for applications that are not included in the predefined settings library1. References:

Windows golden image optimization is the process of reducing the size and improving the performance of the Windows OS image that is used as the base for the desktop pools. Some of the best practices for Windows golden image optimization are:

• Disable unnecessary services: Services that are not required for the desktop functionality or user experience should be disabled to reduce the resource consumption and potential security risks. For example, services such as Windows Search, Windows Defender, Windows Update, and Superfetch can be disabled for better performance and stability.
• Disable power options: Power options such as hibernation and sleep mode should be disabled to free up disk space and avoid potential issues with the desktop state. Hibernation can consume a large amount of disk space by creating a hiberfil.sys file that stores the system memory contents when the desktop is powered off. Sleep mode can cause problems with network connectivity and user sessions when the desktop is resumed from a low-power state.

Other best practices for Windows golden image optimization include:

• Activate Windows OS paging: Paging is a mechanism that allows the OS to use a portion of the disk as virtual memory when the physical memory is insufficient. Paging can improve the performance and stability of the desktops by preventing out-of-memory errors and reducing memory contention. However, paging can also increase disk I/O and wear, so it should be configured with caution and monitored regularly.
• Turn off automatic Windows maintenance (scheduled tasks): Automatic Windows maintenance is a feature that runs various tasks such as disk defragmentation, disk cleanup, security scanning, and system diagnostics in the background. These tasks can consume a lot of CPU, memory, and disk resources and interfere with the user experience and desktop performance. Therefore, it is recommended to turn off automatic Windows maintenance and run these tasks manually or on a scheduled basis when the desktops are not in use.
• Turn off automatic Windows Updates: Automatic Windows Updates is a feature that downloads and installs updates for the OS and other Microsoft products in the background. These updates can consume bandwidth, disk space, and CPU resources and cause compatibility issues with some applications or drivers. Therefore, it is recommended to turn off automatic Windows Updates and manage the updates manually or through a centralized tool such as VMware Update Manager or Microsoft WSUS. References: [Optimizing Your VMware Horizon View 7.x Golden Image] and [VMware Horizon 8.x Professional Course]

On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent. The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12.

The other options are not correct for this scenario:

• Administrator provides this information in the “Add Pool” creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the “Add Pool” creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine. The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3.
• Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment. DNS SRV records are optional and can be configured by the administrator to simplify client connections4.
• Administrator provides this information in the Horizon Agent Installation Wizard on the master image. This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on. The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5.

One of the benefits of using virtual machines is that they are independent of physical hardware. This means that they can run on any compatible host machine, regardless of the underlying hardware components. This also enables them to be migrated, moved, or copied easily from one host to another, without requiring any reconfiguration or installation. This enhances the flexibility and portability of virtual machines, as well as their availability and disaster recovery.

Another benefit of using virtual machines is that they are faster to provision than physical machines. This is because they can be created from templates or snapshots, which contain preconfigured operating systems and applications. This reduces the time and effort needed to install and configure software on each machine. Moreover, virtual machines can be cloned or duplicated quickly, allowing for rapid scaling and deployment of multiple identical instances.

To join two standalone Horizon pods in a Cloud Pod Architecture (CPA) deployment, the administrator needs to perform the following steps:

• On one pod, initialize the CPA. This step creates a pod federation and enables global data replication among all pods in the federation. The pod that initializes the CPA becomes the first pod in the federation67.
• On the second pod, join the CPA. This step adds an existing standalone pod to an existing pod federation. The pod that joins the CPA inherits the global data from the federation89.
• On one pod, create Global Entitlements, and add local pools from each pod. This step allows users to access desktops or applications from any pod in the federation based on their entitlements and load-balancing policies .

The other options are not correct or complete because:

• Initializing the CPA on both pods is not necessary or possible. Only one pod can initialize the CPA and create a pod federation. The other pods must join an existing pod federation68.
• Syncing the CPA on the second pod is not a valid step. Syncing is a process that occurs automatically among all pods in a pod federation to ensure data consistency and availability.
• Creating Cloud Entitlements is not a valid term. The correct term is Global Entitlements, which are used in CPA to entitle users to desktops or applications across multiple pods.

VMware App Volumes is a real-time application delivery system that allows administrators to assign applications to users and groups in Horizon. App Volumes uses virtual disks called packages to store and deliver applications. When a user logs on to a desktop, the App Volumes agent attaches the assigned packages to the desktop and merges them with the OS disk. The user can then access the applications as if they were natively installed.

App Volumes is a suitable solution for deploying an application to specific users in an instant-clone desktop environment with the following characteristics:

• The application needs to be updated very frequently: App Volumes allows administrators to update applications in real time by using the update or push-image operations. These operations replace the existing packages with new ones that have the latest updates applied, without affecting the user data or settings. The updated packages are delivered to the users at the next login or refresh.
• The application needs to be installed as soon as possible: App Volumes allows administrators to install applications quickly and easily by using a clean packaging system and capturing the application installation process. The resulting package can be assigned to users or groups immediately, without requiring any recomposing or rebooting of the desktops.
• The application is not multi-user aware: App Volumes allows administrators to deliver applications that are not multi-user aware by using writable volumes. Writable volumes are user-specific virtual disks that store user-installed applications, data, and settings. Writable volumes can be attached to desktops along with application packages, and they can isolate the user-installed applications from the system-installed applications.

The other options are not suitable for meeting the requirements:

• VMware Horizon Published Application: This option allows administrators to publish applications from RDS hosts to users in Horizon. However, this option requires a separate RDS infrastructure and licensing, and it does not support instant updates or writable volumes for user-installed applications.
• VMware Dynamic Environment Manager: This option allows administrators to manage user profiles and policies in Horizon. However, this option does not deliver or update applications, and it does not support writable volumes for user-installed applications.
• VMware ThinApp: This option allows administrators to package applications into portable executables that can run on any Windows system without installation. However, this option requires a separate packaging process and licensing, and it does not support instant updates or writable volumes for user-installed applications.

The VMware Horizon component that needs to be deployed to allow users to log into VMware Workspace ONE Access and connect to remote desktops and applications without having to provide Active Directory credentials is the Enrollment Server. The Enrollment Server is a standalone service that integrates with VMware Workspace ONE Access and enables True Single Sign-On (SSO) for Horizon clients that are using non-AD-based authentication methods such as RSA SecureID, RADIUS, or SAML1. The Enrollment Server requests short-lived certificates on behalf of the users from a certificate authority (CA), and these certificates are used for authentication to the Horizon environment2. The Enrollment Server must be installed and configured in the same domain or forest as the Connection Server, and it must have an enrollment agent certificate that authorizes it to act as an enrollment agent2.

The other options are not valid or feasible because:

• A Replica Server is a Connection Server instance that replicates the Horizon LDAP configuration data from another Connection Server instance, and provides high availability and load balancing for user connections3. A Replica Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access.
• A Security Server is a Connection Server instance that resides within a DMZ and acts as a proxy for external user connections to the Horizon environment4. A Security Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access. Security Servers are deprecated in Horizon 8 and replaced by Unified Access Gateways (UAGs)4.
• A vCenter Server is a management platform that provides centralized control and visibility of vSphere hosts and virtual machines in the Horizon environment5. A vCenter Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access.

In VMware Horizon, predefined roles such as Inventory Administrators and Desktop Pool Administrators are designed to provide granular access control within the Horizon Console. Inventory Administrators typically have permissions related to managing the overall inventory of virtual desktops and applications, whereas Desktop Pool Administrators are specifically focused on managing and configuring desktop pools, including their settings, assignments, and provisioning.

The reason for the issue is that the administrator may not have added an instant clone domain administrator to VMware Horizon. This is a requirement for creating an automated farm of instant-clone virtual machines using the Add Farm wizard.

An instant clone domain administrator is a user account in Microsoft Active Directory that allows Connection Server to perform certain operations related to instant clones in Active Directory, such as joining instant-clone virtual machines to the domain, creating computer accounts, and deleting computer accounts. The administrator must create and configure this account in Active Directory and then specify the user name and password in VMware Horizon.

To add an instant clone domain administrator to VMware Horizon, the administrator needs to follow these steps:

• In the Horizon Console, select Settings > Domains > Domain Accounts.
• Click Add.
• Enter the domain, user name, and password for the instant clone domain administrator.

After adding the instant clone domain administrator to VMware Horizon, the administrator can proceed with creating an automated farm of instant-clone virtual machines using the Add Farm wizard.

The other options are not the reason for the issue:

• In the Add Farm wizard, the administrator may not have selected Automated Farm as farm type: This option is not relevant to the issue, as the farm type selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which is the first page of the Add Farm wizard.
• The administrator did not prepare a RDSH golden image snapshot: This option is not relevant to the issue, as the RDSH golden image snapshot selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not require a RDSH golden image snapshot.
• The administrator did not add the RDSH golden image to the correct domain: This option is not relevant to the issue, as the RDSH golden image domain selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not require a RDSH golden image domain.

A golden image must have a current snapshot to be used for cloning, and having multiple active snapshots can cause confusion and issues in the provisioning process. Additionally, selecting the correct Guest OS version is crucial for compatibility and optimal performance. These factors must be correctly configured for a VM to appear in the list of available golden images for provisioning.

In VMware Horizon, to designate a Home Site for a user, you would use the "Cloud Pod Architecture" feature, which allows you to set home sites and manage global entitlements across multiple pods and sites in a Horizon environment.

In the exhibit's menu on the left, you should click on "Cloud Pod Architecture" to proceed with designating a Home Site for a user.

VMware vSAN is a storage product that allows the pooling of resources to create datastores in a software defined datacenter. VMware vSAN is a hyper-converged infrastructure solution that integrates compute, storage, and networking resources on industry-standard x86 servers. VMware vSAN aggregates local or direct-attached data storage devices to create a single storage pool shared across all hosts in the vSAN cluster. VMware vSAN enables you to provision and manage storage from the VMware vSphere Web Client or the VMware vCenter Server Appliance Shell. VMware vSAN provides several benefits, such as lower total cost of ownership, simplified management, high performance, scalability, and availability12. References := 1: VMware Horizon 8 Documentation: VMware vSAN Overview 2: VMware Horizon 8 Documentation: Benefits of Using VMware vSAN with Horizon 8
