2V0-51.23 VMware Horizon 8.x Professional Questions and Answers

VMware Horizon Client Configuration

VMware Horizon ' s Dynamic Environment Manager (DEM) is designed to provide a consistent and personalized desktop experience for users across different sessions and desktops. DEM manages user profiles and policies dynamically, ensuring that user settings, preferences, and application configurations are consistent no matter which desktop a user connects to, thus meeting the requirement for a uniform desktop experience.

To access the settings and status of a pool in VMware Horizon, an administrator would navigate to the Inventory > Desktops section of the Horizon Console. By selecting a specific pool, the administrator can view detailed information in the Summary section, including Pool Settings and the status of the image used during the pool ' s deployment, providing insights into the pool ' s configuration and operational status.

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.

Collaboration is a feature that allows users to invite other users to join an existing Windows or Linux remote desktop session with both screen sharing and audio out features enabled. A remote desktop session that is shared in this way is called a collaborative session. The user that shares a session with another user is called the session owner, and the user that joins a shared session is called a session collaborator. A Horizon administrator must enable the Session Collaboration feature for the desktop pool or farm that contains the remote desktops that support collaboration.

One of the requirements to enable Session Collaboration is to use the VMware Blast display protocol for the remote desktops. VMware Blast is a protocol that provides high-performance, high-quality graphics and multimedia delivery over LAN or WAN networks. VMware Blast supports Session Collaboration by allowing multiple users to view and interact with the same remote desktop session simultaneously. Other display protocols, such as PCoIP or RDP, do not support Session Collaboration and will not allow users to share or join collaborative sessions.

Therefore, to enable Session Collaboration in the VMware Horizon environment, the administrator needs to use the BLAST protocol as a requirement.  References :  Configuring Session Collaboration ,  Sharing Remote Desktop Sessions , and [VMware Horizon 8.x Professional Course]

To expand a Writable Volume in VMware Horizon, the administrator needs to navigate to the Volumes > Writables section in the Horizon Console, select the specific volume, and choose the option to update or expand the writable volume. The new size specified must be at least 1GB larger than the current size to ensure there is enough space for the expansion process and to accommodate the growth of user data.

Configuring BLAST Bandwidth Profiles involves setting quality, maximum session bandwidth, and frame rate controls. This can be effectively managed using Horizon Smart Policies within VMware ' s Dynamic Environment Manager (DEM), which allows administrators to create contextual policies that dynamically adapt to the end-user ' s environment. Alternatively, Group Policy Objects (GPOs) can be used to manually set these configurations across the desktop environment, providing a more static approach to enforcing these settings.

Load balancing is a feature that allows administrators to distribute the load of published desktop and application sessions across multiple RDS hosts in a farm. Load balancing can improve the performance and availability of the sessions and the hosts. Horizon offers two ways of configuring load balancing for RDS hosts: using load balancing settings in Horizon Console or using custom load balancing scripts.

The load balancing settings in Horizon Console allow administrators to define how Horizon calculates the server load index, which indicates the load on each RDS host. The server load index can range from 0 to 100, where 0 represents no load and 100 represents full load. A server load index of -1 indicates that load balancing is disabled. Horizon uses the server load index to determine which RDS host is the best candidate for placing a new session request.

The load balancing settings in Horizon Console include the following check boxes that can be selected to influence the load balancing behavior:

The use custom script setting for customized RDSH load balancing: This setting allows administrators to override the default behavior of the load balancing settings and control the placement of new sessions by writing and configuring custom load balancing scripts. The custom scripts must write the server load index to a specific registry key on each RDS host. Horizon will use the value from the registry key instead of calculating it from the other settings.

The Include Session Count setting to include the session count on the RDSH for load balancing: This setting allows administrators to include the number of sessions (connected, pending, and disconnected) on each RDS host as a factor in calculating the server load index. By default, Horizon uses the following formula to calculate the server load index based on the session count: (connected sessions + pending sessions + disconnected sessions)/ (maximum session count). If the maximum session count is configured as unlimited, Horizon falls back to using the absolute number of total sessions.

The other options are not check boxes that can be selected in the load balancing settings in Horizon Console:

The floating dynamic host profile setting, created in the vSphere profile section: This option is not related to load balancing for RDS hosts, but rather to dynamic environment manager for instant-clone desktops. A dynamic host profile is a vSphere profile that contains configuration settings for instant-clone desktops, such as network settings, domain join settings, and customization scripts. A floating dynamic host profile is a type of dynamic host profile that applies to floating desktop pools, where users are assigned a random desktop from a pool at each login.

The Horizon DRS setting for fully automated vSphere load balancing: This option is not related to load balancing for RDS hosts, but rather to distributed resource scheduler (DRS) for vSphere clusters. DRS is a feature that monitors and balances the CPU and memory resources across multiple ESXi hosts in a cluster. DRS can also migrate virtual machines between hosts using vMotion to optimize resource utilization and performance. Horizon DRS is an extension of DRS that integrates with Horizon and provides additional capabilities, such as affinity rules, maintenance mode, and power management. Horizon DRS can be configured with different automation levels, such as fully automated, partially automated, or manual.

The user’s problem is that their settings for the e-mail client are not being saved across sessions. This means that their user profile, which contains their personal data, settings, and preferences, is not being preserved or synchronized properly. To solve this problem, the administrator can deploy one or more of the following options to manage user profiles in Horizon:

VMware App Volumes Writable Volumes: This option allows users to store user-installed applications, data, and settings on a disk independent of the VM. Writable volumes can be attached to desktops along with application packages, and they can isolate the user-installed applications from the system-installed applications. Writable volumes can also be configured to capture specific files and registry keys by using the snapvol.cfg policy file. This option can help users retain their e-mail client settings on a writable volume that is attached to their desktop at each login.

Persona Management: This option allows administrators to manage user profiles by using a remote repository that stores user profiles. Persona Management synchronizes the user profile between the remote repository and the local desktop at login, logout, and at regular intervals during the session. Persona Management also supports profile redirection, which allows administrators to redirect certain folders in the user profile to a network share or a writable volume. This option can help users access their e-mail client settings from the remote repository or the redirected folder at each login.

VMware Dynamic Environment Manager: This option allows administrators to manage user profiles and policies by using a central share that stores user configuration files. Dynamic Environment Manager captures and applies user settings and preferences based on conditions and triggers, such as location, device, or application launch. Dynamic Environment Manager also supports profile archives, which allow administrators to back up and restore user profiles on demand or on schedule. This option can help users apply their e-mail client settings from the central share or the profile archive at each login.

The other options are not valid options for managing user profiles in Horizon:

Roaming Profiles: This option is a native Windows feature that allows users to access their user profile from any computer in a domain by storing it on a network share. However, this option is not recommended for Horizon because it can cause long login times, profile corruption, and data loss due to its synchronous and overwrite behavior. Roaming profiles are also incompatible with instant clones and linked clones.

Flexible profiles: This option does not exist in Horizon or Windows. It might be confused with Flex Profiles, which is a third-party product from Liquidware that provides profile management solutions similar to Dynamic Environment Manager.

The administrator can take two actions to make the golden image show up in the Golden Image selection window. First, they can login to the vSphere Client, select the Golden Image virtual machine and create a snapshot. This will make the golden image available in the selection window. Second, they can login to the vSphere Client, select the Golden Image virtual machine and convert it to a template. This will also make the golden image available in the selection window.

A golden image is a virtual machine that contains the operating system, applications, and settings that are required for an instant clone desktop pool. To create an instant clone desktop pool, the administrator must select a golden image and a snapshot from the vSphere inventory.  The snapshot must be taken after installing and configuring the Horizon Agent on the golden image 1 . If there is no snapshot or no template available, the golden image will not show up in the selection window.

The other options are not correct for this scenario:

Login to the vSphere Client, select the Golden Image virtual machine and delete all snapshots. This option is not correct because deleting all snapshots will not make the golden image show up in the selection window.  In fact, it will prevent the administrator from creating an instant clone desktop pool, as a snapshot is required for instant cloning 2 .

Refresh the Select Golden Image view and select the Golden Image. This option is not correct because refreshing the view will not change the availability of the golden image in the selection window. The administrator must create a snapshot or a template of the golden image before it can be selected.

Login to the vSphere Client, select the Golden Image virtual machine and clone it to a new virtual machine. This option is not correct because cloning the golden image to a new virtual machine will not make it show up in the selection window. The administrator must still create a snapshot or a template of the cloned virtual machine before it can be selected.

The action that must first be performed to ensure that there are no issues with Horizon LDAP replication within the Pod is to execute repadmin.exe/showrepl localhost:389.  This command will display the replication status of the local Connection Server instance and show any errors or warnings that might affect the replication process 1 . The administrator should run this command on each Connection Server instance in the Pod before upgrading them in parallel, and resolve any issues that are reported.

The other options are not valid or feasible because:

Executing ViewDBChk.cmd --scanMachines will not check the Horizon LDAP replication status, but rather scan the vCenter Server inventory for virtual machines that are managed by Horizon and report any inconsistencies or errors 2 . This command is useful for troubleshooting virtual machine issues, but not for verifying LDAP replication.

Executing vdmexport.exe -f Myexport.lDF will not check the Horizon LDAP replication status, but rather export the Horizon LDAP configuration data to a file named Myexport.lDF 3 . This command is useful for backing up or restoring the Horizon LDAP data, but not for verifying LDAP replication.

Executing vdmadmin.exe -S will not check the Horizon LDAP replication status, but rather display the health status of the Connection Server instances in the Pod 4 . This command is useful for monitoring the Connection Server performance and availability, but not for verifying LDAP replication.

To enable an instant-clone pool to use NVIDIA GRID vGPU, the administrator needs to do the following:

Install NVIDIA GRID vGPU in the physical ESXi hosts and select Shared Direct in the Host Graphics Settings 1 2 .

Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use 1 2 .

Take a snapshot of the golden image 1 2 .

In Horizon Console, when creating an instant-clone pool, select Manage Using vSphere Client in the 3D Render field.  Instant-clones inherit the settings configured in the vSphere Client for the golden image 1 2 .

Therefore, the possible reasons for the issue are:

The administrator has selected Shared instead of Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server.  This option is for vSGA, not vGPU 3 .

The golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU.  The administrator needs to verify that the correct vGPU profile is selected and that the NVIDIA drivers are installed in the golden image 4 .

The other options are not valid because:

Horizon 8 does have an explicit 3D renderer option for instant clone, but it is Manage Using vSphere Client, not NVIDIA GRID vGPU 1 2 .

Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are properly configured 1 2 .

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.

In this scenario, Adobe Acrobat 11 has been assigned to a user as an App Volumes package. When the user logs on to VM25, which already has Adobe Acrobat 11 natively installed, the App Volumes agent attaches the package to VM25 and creates a shortcut on the user desktop. However, the package does not overwrite or conflict with the natively installed application. Instead, when the user clicks on the shortcut, the App Volumes package for Adobe Acrobat 11 is opened and runs in an isolated environment. This allows the user to use different versions of the same application without affecting each other or the OS.  References :  App Volumes Architecture  and [VMware Horizon 8.x Professional Course]

VMware Dynamic Environment Manager Application Profiler is a standalone application that simplifies the creation of Flex configuration files and predefined settings for use with VMware Dynamic Environment Manager. Application Profiler analyzes where an application stores its file and registry configuration. The analysis results in an optimized Flex configuration file, which you can edit in the Application Profiler or use directly in the VMware Dynamic Environment Manager environment. With Application Profiler, you can also create application-specific predefined settings, with which you can set the initial configuration state of applications.  Save the Flex configuration file with predefined settings to export the current application configuration state 1 .

Therefore, the two capabilities that are supported by VMware Dynamic Environment Manager Application Profiler are:

It allows creation of application-specific predefined settings. This means that you can configure the default settings for an application that will be applied when a user launches it for the first time.  For example, you can set the language, theme, or preferences of an application using Application Profiler 2 .

It analyzes registry and file system location settings for an application. This means that it monitors the changes that an application makes to the registry and file system when it is running, and generates a Flex configuration file that captures those changes.  This allows VMware Dynamic Environment Manager to manage the user personalization of those settings across different devices and sessions 3 .

The other options are not supported by VMware Dynamic Environment Manager Application Profiler:

It allows individual user personalization of applications. This is not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself.  Application Profiler only helps to create the Flex configuration files that enable user personalization, but it does not apply them to individual users 4 .

It allows third-party user personalization of applications. This is also not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself. Application Profiler only works with applications that store their settings in the registry or file system, and does not support third-party user personalization solutions such as AppSense or RES.

It allows creation of computer templates. This is not a capability of Application Profiler at all. Computer templates are used to create virtual machines or physical computers with a predefined configuration, and are not related to application management or user personalization.

To monitor the advanced metrics of desktop sessions in Horizon Console, you need to use the Horizon Help Desk Tool.  This is a web application that you can use to get the status of Horizon 8 user sessions and to perform troubleshooting and maintenance operations 1 .  You can also view performance details for a virtual or published desktop session that uses the PCoIP or VMware Blast display protocol 2 .

To access the Horizon Help Desk Tool, you need to click on the  Monitoring  tab on the left side of the Horizon Console. Then, you need to select  Help Desk  from the drop-down menu. This will open the Horizon Help Desk Tool in a new browser tab. You can then search for a user, machine, or pool and view the session details.  You can also click on  More  to see the advanced metrics such as latency, bandwidth, protocol, and frame rate 1 .

RADIUS (Remote Authentication Dial-In User Service) supports two-factor authentication and can be integrated with VMware Horizon to secure administrative access to the Horizon Console. RADIUS servers authenticate users based on a combination of something they know (a password) and something they have (a token or mobile app-generated code), providing an added layer of security for administrative logins.

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 federation 6 7 .

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 federation 8 9 .

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 federation 6 8 .

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.

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]

The default URL used to access the Horizon Console is https:// < connection_server_FQDN > /admin, where < connection_server_FQDN > is the fully qualified domain name of the Connection Server instance. This URL allows you to log in to Horizon Console by using a secure (TLS) connection. You can also use the IP address of the Connection Server instance instead of the FQDN, but this might result in blocked access or reduced security due to certificate mismatch. You cannot use https://localhost to connect from the Connection Server host, but you can use https://127.0.0.1 instead. The other options are not valid URLs for Horizon Console.  References :  Log In to Horizon Console

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 SAML 1 .  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 environment 2 .  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 agent 2 .

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 connections 3 . 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 environment 4 . 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 environment 5 . A vCenter Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access.

Access groups are a way of organizing and delegating the administration of machines, desktop pools, application pools, and farms in Horizon. By default, all these objects reside in the root access group, which appears as / or Root (/) in Horizon Console. A high-level administrator can create sub-access groups under the root access group and assign different permissions to different administrators for each access group. For example, a high-level administrator can create an access group called RDS Farms and assign the Inventory Administrators role to a junior-level administrator for that access group. This way, the junior-level administrator can see and manage all the RDS farms that are in the RDS Farms access group, but not the ones that are in other access groups or the root access group. Therefore, to correct the issue of a junior-level administrator not being able to see all RDS farms, a high-level administrator needs to make changes to the access groups and the permissions associated with them.  References :  Understanding Permissions and Access Groups  and [VMware Horizon 8.x Professional Course]

To improve the user experience when using Application Profiler from Dynamic Environment Manager to create application-specific user defined settings, the administrator can configure exclusions to filter out unnecessary folders and registry entries. Exclusions are rules that specify which file system or registry locations are not included in the Flex configuration file.  Exclusions can reduce the size of the Flex configuration file and the profile archive, and improve the performance of the application profiling and synchronization processes 1 2 .

The other options are not valid or effective because:

Changing the default save path does not affect the size or content of the Flex configuration file or the profile archive.  It only changes where the files are stored on the local machine 3 .

Using Deepest Registry Path does not reduce the size of the Flex configuration file or the profile archive.  It only changes how the registry locations are displayed in the Application Profiler interface 4 .

There is no such thing as Cloud Entitlements in Dynamic Environment Manager.  The correct term is Global Entitlements, which are used in Cloud Pod Architecture to entitle users to desktops or applications across multiple pods 5 .
