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

To entitle users and groups to pools, you need to perform the following steps:

• During pool creation in the entitlement pane, click on add, search for users and groups in the Active Directory, continue and finish the pool creation. This option allows you to entitle users and groups to a desktop or application pool at the same time as you create the pool3.
• Navigate to Inventory > Desktops > check mark a pool > click on Add Entitlement. This option allows you to add entitlements to an existing desktop or application pool after you create the pool4.
• Navigate to Users and Groups > Entitlements > click on Entitlements > click on Add Entitlements, search for users and groups in the Users pane and add the desired desktop pool in the next pane Desktop Pools. This option allows you to review and manage the entitlements for users and groups from a single location5.

The other options are not required or valid for entitling users and groups to pools. Running the Active Directory entitlement script in the golden master is not necessary as Horizon 8 automatically synchronizes with Active Directory domains that are configured in Horizon Console6. Specifying the desired Active Directory OU for the VMs during pool creation does not automatically add the preconfigured associated user group to the Horizon entitlements as you still need to select the users or groups from the search results7. References := 3: VMware Horizon 8 Documentation: Add Entitlements During Pool Creation 4: VMware Horizon 8 Documentation: Add Entitlements After Pool Creation 5: VMware Horizon 8 Documentation: Review and Manage Entitlements 6: VMware Horizon 8 Documentation: Active Directory Requirements for Horizon Connection Server 7: VMware Horizon 8 Documentation: Create an Automated Desktop Pool

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.

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.

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.

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]

Writable Volumes are user-specific virtual disks that store user-installed applications, data, and settings. App Volumes is a real-time application delivery system that uses Writable Volumes to deliver applications that are not multi-user aware. However, sometimes it might be necessary to prevent App Volumes from persisting specific data between sessions, such as temporary files, application updates, or registry keys. To do this, administrators can specify exclusions for Writable Volumes in a policy file called snapvol.cfg.

The snapvol.cfg file is a text file that contains policy settings for App Volumes. These settings determine which files and registry keys are captured or excluded by App Volumes. The snapvol.cfg file can be customized by administrators to suit different needs and scenarios. The snapvol.cfg file can be applied to both application packages and Writable Volumes.

To specify exclusions for Writable Volumes, administrators can use the following keywords in the snapvol.cfg file:

• exclude_uwv_file: This keyword excludes a file or folder path from being persisted on a Writable Volume. For example, exclude_uwv_file=\Program Files (x86)\Notepad++ excludes the folder location of Notepad++ from being overwritten during an update.
• exclude_uwv_reg: This keyword excludes a registry key or value from being persisted on a Writable Volume. For example, exclude_uwv_reg=\REGISTRY\MACHINE\SOFTWARE\Notepad++ excludes the registry location of Notepad++ from being overwritten during an update.

The snapvol.cfg file must be uploaded to the Writable Volume by using the Update Writable Volumes feature in App Volumes Manager. The exclusions will take effect after the user logs off and logs back in to the desktop.

The other options are not valid files for specifying exclusions for Writable Volumes:

• config.ini: This file is used to configure the App Volumes agent settings, such as the App Volumes Manager address, the logging level, and the SSL certificate validation.
• svservice.log: This file is used to record the App Volumes agent log messages, such as the agent status, the package attachment, and the error messages.
• json.cfg: This file does not exist in App Volumes.

Thin Clients and Zero Clients have the lowest cost of ownership and are easier to manage due to their minimalistic design, which lacks a full operating system, resulting in fewer components that require updates. These clients are designed for remote desktop services like VMware Horizon, where the computing work is done on the server side, making firmware updates and monitoring simpler and more centralized.

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 processes12.

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 machine3.
• 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 interface4.
• 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 pods5.

• SAML -> Connects the client to Workspace ONE Access
• Certificate Authority -> Issues certificates for vrm and Enrollment Server
• Connection Server -> Connects vrm to Active Directory
• Enrollment Server -> Connects Workspace ONE Access to vrm

You can find more information about the Simple True 5SO Architecture in the VMware Horizon 8.x Professional source documents or study guide1. This architecture is a simplified version of the True SSO Architecture, which allows users to log in to their virtual desktops and applications without entering credentials multiple times. The Simple True 5SO Architecture uses Workspace ONE Access as the identity provider, which authenticates users with SAML and issues SAML assertions. The Enrollment Server then uses the SAML assertions to request short-lived certificates from the Certificate Authority, which are used to authenticate users to the Connection Server. The Connection Server then connects users to their virtual desktops and applications through vrm, which is integrated with Active Directory2.

To enable debug logging for a single user in VMware Dynamic Environment Manager, the administrator needs to create an empty FlexDebug.txt file in the same folder as the standard log file for this user. This will trigger FlexEngine to switch to debug logging for this particular user1. Debug logging is useful for troubleshooting purposes, as it provides more detailed information about the FlexEngine operations and actions1.

The other options are not correct because:

• Updating the FlexEngine registry to DEBUG will not enable debug logging for a single user, but for all users who log on to the same computer. This option can only be set through Group Policy settings and applies to all users1. Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.
• Creating an empty FlexDebug.log file in the log folder will not enable debug logging for a single user, as the file name must be exactly FlexDebug.txt. The file extension must be .txt, not .log1.
• Configuring the FlexEngine GPO to DEBUG will not enable debug logging for a single user, but for all users who are affected by the GPO. This option can only be set through Group Policy settings and applies to all users1. Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.

To correctly sequence the TLS Certificate Configuration Steps:

• Get a new signed TLS certificate from a CA. Before making any modifications or importing the certificate, you'll first need to obtain a new signed TLS certificate from a Certificate Authority (CA). So, this should be Step 1.
• Import the TLS certificate into the Windows local computer certificate store. After obtaining the new signed TLS certificate, the next logical step is to import this certificate into the Windows local computer certificate store. This would be Step 2.
• Modify the certificates/ friendly names to vdm and reflect the current active certificate. Once the certificate is imported, the next step is to modify its friendly names to ensure the Horizon Service recognizes and uses this certificate. This becomes Step 3.
• Restart Horizon Service. Finally, after all the modifications and configurations are done, you should restart the Horizon Service to apply the changes. This is Step 4.

In summary:

The following is the correct answer for the drag and drop question:

• Administrator -> Performs all desktop, session, and pool-related operation.
• Inventory Administrator -> Performs all administrative functions and applies to an Access Group.
• Local Administrator -> No rights to manage Cloud Pod or the Global Data Layer.

Predefined Administrator Roles (vmware.com)

The predefined administrator roles in Horizon console are designed to provide different levels of access and control over the Horizon environment. Each role has a set of privileges that grant the ability to perform specific actions or view certain information. You can assign these roles to users or groups on the root access group, which gives them access to all inventory objects in the system, or on a specific access group or federation access group, which limits their scope to the objects within that group. You cannot modify the predefined roles, but you can create custom roles by selecting individual privileges.

The Administrator role is the most powerful role in Horizon console. It allows the user to perform all administrative operations, including creating and managing desktop pools, sessions, farms, applications, global settings, and other administrators. In a Cloud Pod Architecture environment, this role also enables the user to configure and manage a pod federation and manage remote pod sessions. The Administrator role on the root access group is equivalent to a super user role, as it gives full access to everything in the system. Therefore, you should assign this role to a limited number of users.

The Inventory Administrator role is similar to the Administrator role, but it applies only to an access group. This means that the user can perform all administrative functions on the inventory objects that belong to that access group, such as desktop pools, farms, applications, and sessions. However, the user cannot manage global settings or other administrators. This role is useful for delegating administration of specific resources to different users or groups.

The Local Administrator role is a restricted version of the Inventory Administrator role. It applies only to an access group and does not grant any rights to manage Cloud Pod Architecture features or the Global Data Layer. This means that the user can only manage local inventory objects within that access group, such as desktop pools, farms, applications, and sessions. This role is suitable for administrators who do not need to access or modify global settings or cross-pod resources.

The Help Desk Administrator role is a specialized role that allows the user to perform desktop and application actions for troubleshooting and support purposes. These actions include shutting down, resetting, restarting, logging off, disconnecting, and sending messages to users’ desktops or applications. The user can also perform remote assistance actions such as ending processes or viewing system information for a user’s desktop or application. The user cannot create or modify any inventory objects or settings with this role.

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]

One of the possible reasons that the administrator is not seeing the printers within his Horizon Desktop session is that printing is disabled in the Horizon Desktop Pool. Printing is a feature that allows users to print from a remote desktop to any local or network printer available on their client device. Printing can be enabled or disabled for each desktop pool by using the VMware Integrated Printing feature.

VMware Integrated Printing is a feature that supports client printer redirection, location-based printing, and persistent print settings. Client printer redirection enables users to print from a remote desktop to any local or network printer available on their client device. Location-based printing enables users to print to network printers that are physically near their client device. Persistent print settings enable users to retain their print settings across sessions.

To enable or disable printing for a desktop pool, the administrator needs to follow these steps:

• In Horizon Console, select Inventory > Desktops.
• Select the desktop pool and click Edit.
• In the Edit Desktop Pool dialog box, select the VMware Integrated Printing tab.
• Select or clear the Enable VMware Integrated Printing check box.
• Click OK.

If printing is disabled for a desktop pool, users will not see any printers within their Horizon Desktop session, even if they have installed the VMware Integrated Printing feature in the Horizon Agent and the Horizon Client. Therefore, to resolve this issue, the administrator needs to enable printing for the desktop pool by selecting the Enable VMware Integrated Printing check box.

The other options are not likely to be the reason that the administrator is not seeing the printers within his Horizon Desktop session:

• Port TCP 9427 is disabled: This port is used by the VMware Integrated Printing feature for communication between the Horizon Agent and the Horizon Client. If this port is disabled, users might experience printing errors or delays, but they should still see the printers within their Horizon Desktop session.
• The VMware Integrated Printing feature is not installed in the Horizon Client: This feature is installed by default in the Horizon Client for Windows, Mac, Linux, Chrome, and HTML Access. If this feature is not installed in the Horizon Client, users might not be able to print from their remote desktops, but they should still see the printers within their Horizon Desktop session.
• Port TCP 32111 is disabled: This port is used by ThinPrint for communication between the Horizon Agent and the ThinPrint Client. ThinPrint is a legacy printing feature that has been replaced by VMware Integrated Printing. If this port is disabled, users might experience printing errors or delays with ThinPrint, but they should still see the printers within their Horizon Desktop session if they use VMware Integrated Printing.

In the Group Policy Management Editor window shown, the administrator should configure the "VMware Horizon Performance Tracker" setting to be able to see the desktop VM's active session in the vSphere Console. However, this setting is not directly visible in the screenshot provided. The Performance Tracker is a tool that enables the monitoring of session performance and is used for this purpose.

In the list shown, there is no specific setting under "VMware Blast" that directly allows for the monitoring of active sessions in the vSphere Console. Typically, active session monitoring in the vSphere Console is not solely managed via Group Policy but also involves settings within the VMware Horizon Console itself and the vSphere infrastructure.

If the task requires enabling something from Group Policy for better visibility or performance tracking of the VM's active sessions, then the closest relevant setting in the context of VMware Blast would be the "VMware Horizon Performance Tracker" if it was listed or part of another category in the Group Policy settings.

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.

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.

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

The disconnections of external sessions while internal sessions remain stable suggest an issue with the network infrastructure external to the Horizon environment, specifically with the load balancer placed in front of the Unified Access Gateway (UAG) appliances. Misconfigurations such as improper session persistence settings can lead to sessions being disconnected or improperly routed, causing the observed random disconnections.
