Answer : B, E

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.

Answer : B

Answer : B, D

VMware Dynamic Environment Manager Application Profiler is a standalone application that simplifies the creation of Flex configuration files and predefined settings for use with VMware Dynamic Environment Manager. Application Profiler analyzes where an application stores its file and registry configuration. The analysis results in an optimized Flex configuration file, which you can edit in the Application Profiler or use directly in the VMware Dynamic Environment Manager environment. With Application Profiler, you can also create application-specific predefined settings, with which you can set the initial configuration state of applications.Save the Flex configuration file with predefined settings to export the current application configuration state1.

Therefore, the two capabilities that are supported by VMware Dynamic Environment Manager Application Profiler are:

It allows creation of application-specific predefined settings. This means that you can configure the default settings for an application that will be applied when a user launches it for the first time.For example, you can set the language, theme, or preferences of an application using Application Profiler2.

It analyzes registry and file system location settings for an application. This means that it monitors the changes that an application makes to the registry and file system when it is running, and generates a Flex configuration file that captures those changes.This allows VMware Dynamic Environment Manager to manage the user personalization of those settings across different devices and sessions3.

The other options are not supported by VMware Dynamic Environment Manager Application Profiler:

It allows individual user personalization of applications. This is not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself.Application Profiler only helps to create the Flex configuration files that enable user personalization, but it does not apply them to individual users4.

It allows third-party user personalization of applications. This is also not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself. Application Profiler only works with applications that store their settings in the registry or file system, and does not support third-party user personalization solutions such as AppSense or RES.

It allows creation of computer templates. This is not a capability of Application Profiler at all. Computer templates are used to create virtual machines or physical computers with a predefined configuration, and are not related to application management or user personalization.

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.

Dual monitors configured using PCoIP does not span both the monitors for VMware View and Connecting to a VDI desktop with PCoIP displays a black screen and disconnects after 10 seconds

Answer : A

The default URL used to access the Horizon Console is https://<connection_server_FQDN>/admin, where <connection_server_FQDN> is the fully qualified domain name of the Connection Server instance. This URL allows you to log in to Horizon Console by using a secure (TLS) connection. You can also use the IP address of the Connection Server instance instead of the FQDN, but this might result in blocked access or reduced security due to certificate mismatch. You cannot use https://localhost to connect from the Connection Server host, but you can use https://127.0.0.1 instead. The other options are not valid URLs for Horizon Console.Reference:Log In to Horizon Console

Answer : A, C

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.

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.
