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.

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.

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.

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]

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 image1. 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 cloning2.

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.

For instant-clone operations in Active Directory, the user account used by VMware Horizon needs specific permissions to manage computer objects effectively. These include the ability to create and delete child objects and computer objects, as well as read and write all properties of those objects. These permissions ensure that Horizon can create, modify, and clean up computer accounts associated with instant clones, facilitating seamless desktop provisioning and management.

A Trusted Platform Module (vTPM) is a virtualized version of a physical TPM device that provides enhanced security for virtual machines. A vTPM device can be added to a virtual machine to enable features such as encryption, attestation, and key management. A vTPM device requires a Key Management Server (KMS) to store and manage the encryption keys.

To create instant clones VMs with a vTPM device, the vCenter Server user must have certain privileges in addition to those required for instant clones without a vTPM device. One of these privileges is Manage KMS, which allows the user to perform cryptographic operations on the vTPM device, such as cloning, decrypting, encrypting, migrating, and registering. The Manage KMS privilege is part of the Cryptographic operations privilege group on vCenter Server.

The other options are not required only for instant clones VMs with a vTPM device:

Upgrade virtual machine compatibility: This privilege allows the user to upgrade the virtual hardware version of a virtual machine to support new features and capabilities. This privilege is required for instant clones VMs regardless of whether they have a vTPM device or not.

Configure Host USB device: This privilege allows the user to configure USB devices on an ESXi host and attach them to a virtual machine. This privilege is not related to vTPM devices or instant clones VMs.

Manage custom attributes: This privilege allows the user to create, edit, and delete custom attributes for vCenter Server objects. Custom attributes are user-defined fields that can store additional information about objects. This privilege is not related to vTPM devices or instant clones VMs.

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.

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]
