Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

To create an instant-clone desktop pool, you must first create a golden image virtual machine and take a snapshot of it in a powered-down state. This snapshot provides the base image for the clones. You cannot create an instant-clone desktop pool from a VM template or a powered-on VM. Therefore, the administrator must take a snapshot of the VM that is the golden image before creating the new desktop pool. References: Create an Instant-Clone Desktop Pool and Instant Clone Desktop Pools

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:

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

To increase the capacity and resiliency of VMware Horizon desktop pools, deploying Horizon on VMware Cloud on AWS or in a remote data center are viable options. VMware Cloud on AWS provides a scalable and secure cloud platform, allowing for quick expansion and disaster recovery capabilities. Similarly, deploying Horizon in a remote data center can provide geographical diversity, reducing the impact of localized disasters and improving overall resilience.

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.

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.

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.

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]

• 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.

A black screen when connecting to a Horizon virtual desktop can be caused by various reasons, such as network issues, hardware issues, Horizon tunnel issues, or underlying guest operating system issues. Based on the options given, the following could be the cause of the issue:

• A vRAM shortage on the Horizon virtual machine. This can affect the display performance and cause a black screen or a disconnect. To resolve this issue, you should configure the pool to provide enough video memory for the resolutions you plan to present to the clients1.
• The incorrect video driver version installed on the Horizon virtual machine. This can cause compatibility issues and prevent the display protocol from working properly. To resolve this issue, you should verify that the View desktop is using the correct video driver and that it is compatible with the VMware Tools and Horizon Agent versions installed23.
• An incorrect firewall configuration. This can block or misroute the display protocol traffic and cause a connection failure. To resolve this issue, you should verify that the required ports are open between the client, UAG/Security server/Connection server, and VDI machine4 .

The other options are not likely to cause a black screen when connecting to a Horizon virtual desktop:

• The client machine video memory is too high. This should not affect the display protocol performance or cause a black screen. The client machine video memory is only used to render the display on the local device, not on the remote desktop.
• The Horizon virtual machine video memory is too high. This should not cause a black screen or a disconnect either. The Horizon virtual machine video memory is used to allocate resources for the display protocol on the server side, not on the client side.

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.

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.

In VMware Horizon, the Pre-Launch feature allows for the initiation of applications immediately after user authentication, reducing the launch time of frequently used applications. By editing the application pool settings and enabling the Pre-Launch option, administrators can improve user experience by having critical applications ready as soon as the authentication process is completed.

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.

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 Settings12.
• Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use12.
• Take a snapshot of the golden image12.
• 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 image12.

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 vGPU3.
• 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 image4.

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 vGPU12.
• Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are properly configured12.

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.

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.

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.

If the Horizon Console does not display the health status of configured Unified Access Gateways (UAGs), it could be due to improper firewall configuration blocking traffic on port 443, which is essential for secure communication. Additionally, a discrepancy between the system name in UAG and the name entered in the Horizon Console can also prevent the console from correctly retrieving and displaying the UAG's health status.

VMware Blast policy settings are stored in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\Config on the remote desktops or RDS hosts that use the VMware Blast display protocol. These settings can be configured by using the VMware Blast ADMX template file (vdm_blast.admx) and applying it through Microsoft Group Policy Object (GPO). Some of these settings can be changed in real time, which means that they take effect immediately after the policy is applied, without requiring a reboot or a reconnection of the Horizon Client. However, some of these settings cannot be changed in real time, which means that they require a reboot or a reconnection of the Horizon Client to take effect.

The effect of changing any VMware Blast policy that cannot be changed in real time is that the Microsoft GPO update rules apply and GPOs are updated manually or by restarting the Horizon Agent. This means that the new policy settings will not be applied until one of the following events occurs:

• The Horizon Agent service is restarted on the remote desktop or RDS host. This can be done manually by using the Services console or the command-line tool sc.exe, or automatically by using a scheduled task or a script.
• The remote desktop or RDS host is rebooted. This can be done manually by using the Restart option in Windows, or automatically by using a scheduled task or a script.
• The Group Policy refresh interval is reached. This is a configurable time interval that determines how often the system checks for and applies new or changed GPOs. By default, this interval is 90 minutes for domain members and 5 minutes for domain controllers, with a random offset of 0 to 30 minutes. This interval can be modified by using the Group Policy refresh interval for computers setting in the Computer Configuration\Administrative Templates\System\Group Policy folder of the Group Policy Management Console.

Therefore, to ensure that the VMware Blast policy settings that cannot be changed in real time are applied as soon as possible, it is recommended to restart the Horizon Agent service or reboot the remote desktop or RDS host after applying the policy.

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.
