To deploy a RDS desktop pool with the new standard of Windows Server 2019, the steps should be ordered as follows:

• Prepare the Windows Server 2019 golden image. This is the first step because you'll need a prepared OS image to base your RDS desktop pool on.
• Add an Automated Farm. Once your golden image is ready, you can set up an automated farm for the RDS desktop pool.
• Add a RDS desktop pool. Using the automated farm and the prepared golden image, you can now add the RDS desktop pool.
• Entitle AD users and/or groups. With the RDS desktop pool in place, the next step is to give Active Directory (AD) users and groups the necessary entitlements to access the desktops.
• Launch Horizon Client and verify access to RDS desktop. As the final verification step, launch the Horizon Client to ensure that you can access the newly created RDS desktop pool and that everything is functioning as expected.

So, the sequential order is: Prepare the Windows Server 2019 golden image -> Add an Automated Farm -> Add a RDS desktop pool -> Entitle AD users and/or groups -> Launch Horizon Client and verify access to RDS desktop.

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.

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.

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:

Integrating a Linux OS-based desktop into Active Directory can be achieved using Winbind for domain joining and authentication, Windows Domain Join through tools like Samba, and System Security Services Daemon (SSSD) for LDAP authentication against Active Directory. These methods enable Linux desktops to participate in a Windows-centric environment, allowing for centralized authentication and management.

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.

Unified Access Gateway (UAG) is a secure gateway appliance that provides access to VMware Horizon based resources such as virtual desktops, RDSH-based applications, and physical Windows machines. UAG supports multiple authentication methods and protocols, such as SAML, OAuth, and RADIUS, to provide secure access to end users from any device and location. UAG also provides edge services such as load balancing, high availability, and firewall rules to optimize the performance and availability of Horizon based resources12. References := 1: VMware Horizon Architecture Planning: Unified Access Gateway 2: VMware Unified Access Gateway Administration Guide: Introduction to Unified Access Gateway

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.

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.

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

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.
