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 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 process1. 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 errors2. 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.lDF3. 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 Pod4. This command is useful for monitoring the Connection Server performance and availability, but not for verifying LDAP replication.

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.

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.

For a global entitlement to include local desktop pools, the settings and configurations of the global entitlement must be compatible with those of the local pools. If there is a mismatch in settings, such as display protocol, user assignment type (dedicated or floating), or other critical configurations, the local pools will not appear as selectable options when adding them to a global entitlement.

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

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 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.

Cloud Pod Architecture is a feature that allows administrators to link multiple Horizon pods across sites and data centers to form a single logical entity called a pod federation. Cloud Pod Architecture enables global entitlements, which allow users to access desktops and applications from any pod in the pod federation. Cloud Pod Architecture also provides load balancing, high availability, and disaster recovery capabilities for Horizon deployments.

However, Cloud Pod Architecture has some feature limitations that administrators should be aware of. Two of these limitations are:

• Cloud Pod Architecture does not support Active Directory two-way trusts between domains: This means that the domains that contain the Horizon pods in the pod federation must have a one-way trust relationship, where the domain that contains the Cloud Pod Architecture home site trusts all the other domains, but not vice versa. A two-way trust relationship, where each domain trusts and is trusted by all the other domains, is not supported by Cloud Pod Architecture and can cause authentication and entitlement issues.
• Kiosk mode clients are not supported unless a workaround has been implemented: This means that users who log in to Horizon Client in kiosk mode, which is a mode that allows users to access a single desktop or application without entering credentials, cannot access desktops or applications from a Cloud Pod Architecture implementation. Kiosk mode clients are not compatible with global entitlements and load balancing features of Cloud Pod Architecture. However, there is a workaround that involves creating a dedicated user account and a dedicated desktop pool for each kiosk mode client and using a script to launch Horizon Client with the appropriate parameters. For instructions, see VMware Knowledge Base (KB) article 21488881.

The other options are not limitations of Cloud Pod Architecture:

• Cloud Pod Architecture is supported with Unified Access Gateway appliances: Unified Access Gateway is a platform that provides secure edge services for Horizon deployments, such as secure remote access, load balancing, and authentication. Unified Access Gateway is compatible with Cloud Pod Architecture and can be configured to route user requests to the appropriate pod in the pod federation based on global entitlements and load balancing policies.
• Cloud Pod Architecture can span multiple sites and data centers simultaneously: This is one of the main benefits of Cloud Pod Architecture, as it allows administrators to scale up and out their Horizon deployments across different geographic locations and network boundaries. Cloud Pod Architecture can support up to 15 pods per pod federation and up to 5 sites per pod federation, with a maximum of 200,000 sessions per pod federation.
• The Cloud Pod Architecture feature is supported in an IPv6 environment: IPv6 is the latest version of the Internet Protocol that provides a larger address space and enhanced security features for network communication. Cloud Pod Architecture supports IPv6 environments and can operate in mixed IPv4 and IPv6 environments as well.

VMware vCenter Server is the central management component for ESXi servers, allowing administrators to manage multiple ESXi hosts and virtual machines (VMs) from a single console. It provides essential management capabilities, including resource allocation, performance monitoring, and centralized access control, making it the cornerstone for managing a VMware virtualized infrastructure.

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.

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 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.

• 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 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 operations1. You can also view performance details for a virtual or published desktop session that uses the PCoIP or VMware Blast display protocol2.

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 rate1.

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.

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.

The two options that are available for the administrator to make the shortcut available to all desktop pool users, while minimizing ongoing administrative effort, before updating the desktop pool golden image are:

• Copy the shortcut to c:\users\Public\Desktop. This option will place the shortcut in the public desktop folder, which is shared by all users who log on to the same computer. The public desktop folder is normally a hidden folder, so the administrator needs to enable the option to show hidden files and folders in File Explorer1. This option does not require any additional software or configuration, but it will only work for the existing desktops in the pool. If new desktops are added or refreshed, the shortcut will not be copied automatically.
• Configure a Shortcut with DEM (Dynamic Environment Manager). This option will use the DEM console to create a shortcut configuration that will apply the shortcut to the user’s desktop during logon2. The administrator needs to install and configure DEM on the Horizon environment, and create a configuration share and a profile archive share for storing the DEM settings3. This option requires more initial setup, but it will work for any desktop in the pool, regardless of whether it is new or refreshed. It also allows more flexibility and control over the shortcut properties and conditions.

The other options are not valid or feasible because:

• Copying the shortcut during user provisioning to a non-writeable App Volume will not work because App Volumes are used to deliver applications, not shortcuts. App Volumes are virtual disks that are attached to the virtual machines at runtime, and they contain application files, registry entries, and settings4. Copying a shortcut to an App Volume will not make it appear on the user’s desktop.
• Copying the shortcut to the Windows Default Domain Controller Policy will not work because this policy is used to configure settings for domain controllers, not desktops. The Default Domain Controller Policy is a Group Policy Object (GPO) that is linked to the Domain Controllers organizational unit (OU) in Active Directory, and it contains security settings that are applied to all domain controllers in the domain5. Copying a shortcut to this policy will not affect any desktops in the Horizon environment.
• Configuring a Shortcut with Horizon View Client will not work because Horizon View Client is used to connect to remote desktops and applications, not to create shortcuts. Horizon View Client is a software application that runs on various devices and platforms, and it allows users to access their virtual desktops and applications through a secure connection6. Configuring a shortcut with Horizon View Client will not make it appear on the user’s desktop.

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:

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]
