Navigate to Users and Groups > Entitlements > click on Entitlements > click on Add Entitlements, search for users and groups in the Users pane and add the desired desktop pool in the next pane Desktop Pools.

Q34. In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected.
What happens if one of these Connection Servers runs into an unplanned outage?

All 450 active sessions are disconnected, and have to re-connect again by the end-user.

All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled.

All 450 active session are logged off immediately.

Only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled.

In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected.
If one of these Connection Servers runs into an unplanned outage, only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled. This means that the other two Connection Servers can still handle the remaining sessions without interruption.
The HTTPS Secure Tunnel is a feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications through the Connection Server. When this feature is enabled, all the display protocol traffic is tunneled through the Connection Server, which acts as a proxy between the client and the desktop. This increases the security and simplifies the network configuration, but also adds some overhead and dependency on the Connection Server availability1.
When this feature is disabled, the Horizon Client devices connect directly to the desktops using their IP addresses or hostnames, bypassing the Connection Server. This reduces the load and dependency on the Connection Server, but also requires more network configuration and firewall rules to allow direct access to the desktops2.
The Blast Secure Gateway is a similar feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications using the Blast Extreme protocol through the Connection Server. When this feature is enabled, the Blast Extreme traffic is tunneled through the Connection Server, which acts as a gateway between the client and the desktop. When this feature is disabled, the Horizon Client devices connect directly to the desktops using Blast Extreme3.
In this scenario, both HTTPS Secure Tunnel and Blast Secure Gateway are disabled, which means that the Horizon Client devices connect directly to the desktops using Blast Extreme. Therefore, if one of the Connection Servers fails, only the sessions that were authenticated by that Connection Server are affected. The other sessions can continue without interruption, as long as they can reach their desktops directly4.
The other options are not correct for this scenario:
All 450 active sessions are disconnected, and have to re-connect again by the end-user. This would be true if HTTPS Secure Tunnel or Blast Secure Gateway were enabled, and all the display protocol traffic was tunneled through the Connection Server. In that case, any failure of a Connection Server would disconnect all the sessions that were using it as a proxy5.
All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled. This would be true if there was no dependency on the Connection Server after authentication.
However, even with HTTPS Secure Tunnel and Blast Secure Gateway disabled, there is still some communication between the Horizon Client and the Connection Server for session management and heartbeat monitoring. If a Connection Server fails, these communications are lost and the sessions are terminated.
All 450 active session are logged off immediately. This would be true if there was a global setting in Horizon Console to log off users when a Connection Server fails. However, there is no such setting in Horizon Console. The default behavior is to disconnect users when a Connection Server fails, not log them off.

Q36. What is the default URL used to access the Horizon Console?

https://<connection_server_FQDN>/admin

https://<connection_server_FQDN>/default

https://<connection_server_IP>/administrator

https://<connection_server_IP>/login

Q37. A Horizon administrator does not see the health status for the Unified Access Gateways (UAG) they configured in the Horizon Console.
What two options could be causing the issue? (Choose two.)

The Connection Server needs to be rebooted.

The firewall hasn’t been configured properly to allow traffic on port 443.

Another license is needed for UAG health overview.

The pod needs to be added to the Cloud Pod Federation.

The name entered in the Horizon console doesn’t match up with the system name in UAG.

Q38. On a VMware vCenter managed virtual machine, how does the VMware Horizon Agent know which Connection Server it should register with during the Instant Clone pool creation process?

Administrator provides this information in the “Add Pool” creation wizard.

Horizon Agent retrieves this information from an DNS SRV record.

Administrator provides this information in the Horizon Agent Installation Wizard on the master image.

Horizon Agent queries VMware Tools for a Guestlnfo Variable during the cloning process.

Explanation
On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent. The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12.
The other options are not correct for this scenario:
Administrator provides this information in the “Add Pool” creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the “Add Pool” creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine. The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3.
Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment. DNS SRV records are optional and can be configured by the administrator to simplify client connections4.
Administrator provides this information in the Horizon Agent Installation Wizard on the master image.
This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on. The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5.

Q39. Adobe Acrobat 11 has been assigned to a user. VM25 already has Adobe Acrobat 11 and is natively installed.
What happens when the user logs on to VM25?

The App Volume package does not get attached because the natively installed application has priority.

The user-assigned application is attached to VM25. When the user clicks on the application shortcut, the App Volume package for Adobe Acrobat 11is opened.

Although a shortcut to the App Volume package is created on the user desktop, the application does not get attached to VM25.

A shortcut to the user-assigned application is created on the user desktop, and when they click on the shortcut, the application gets attached to VM25.

Q40. An administrator is configuring load-balancing settings in Horizon Console for a RDSH Farm. Which two check boxes can be selected to influence the load balancing behavior? (Choose two.)

The floating dynamic host profile setting, created in the vSphere profile section.

The use custom script setting for customized RDSH load balancing.

The Include Session Count setting to include the session count on the RDSH for load balancing.

The Horizon DRS setting for fully automated vSphere load balancing.

Explanation
Load balancing is a feature that allows administrators to distribute the load of published desktop and application sessions across multiple RDS hosts in a farm. Load balancing can improve the performance and availability of the sessions and the hosts. Horizon offers two ways of configuring load balancing for RDS hosts: using load balancing settings in Horizon Console or using custom load balancing scripts.
The load balancing settings in Horizon Console allow administrators to define how Horizon calculates the server load index, which indicates the load on each RDS host. The server load index can range from 0 to 100, where 0 represents no load and 100 represents full load. A server load index of -1 indicates that load balancing is disabled. Horizon uses the server load index to determine which RDS host is the best candidate for placing a new session request.
The load balancing settings in Horizon Console include the following check boxes that can be selected to influence the load balancing behavior:
The use custom script setting for customized RDSH load balancing: This setting allows administrators to override the default behavior of the load balancing settings and control the placement of new sessions by writing and configuring custom load balancing scripts. The custom scripts must write the server load index to a specific registry key on each RDS host. Horizon will use the value from the registry key instead of calculating it from the other settings.
The Include Session Count setting to include the session count on the RDSH for load balancing: This setting allows administrators to include the number of sessions (connected, pending, and disconnected) on each RDS host as a factor in calculating the server load index. By default, Horizon uses the following formula to calculate the server load index based on the session count: (connected sessions + pending sessions + disconnected sessions)/ (maximum session count). If the maximum session count is configured as unlimited, Horizon falls back to using the absolute number of total sessions.
The other options are not check boxes that can be selected in the load balancing settings in Horizon Console:
The floating dynamic host profile setting, created in the vSphere profile section: This option is not related to load balancing for RDS hosts, but rather to dynamic environment manager for instant-clone desktops. A dynamic host profile is a vSphere profile that contains configuration settings for instant-clone desktops, such as network settings, domain join settings, and customization scripts. A floating dynamic host profile is a type of dynamic host profile that applies to floating desktop pools, where users are assigned a random desktop from a pool at each login.
The Horizon DRS setting for fully automated vSphere load balancing: This option is not related to load balancing for RDS hosts, but rather to distributed resource scheduler (DRS) for vSphere clusters. DRS is a feature that monitors and balances the CPU and memory resources across multiple ESXi hosts in a cluster. DRS can also migrate virtual machines between hosts using vMotion to optimize resource utilization and performance. Horizon DRS is an extension of DRS that integrates with Horizon and provides additional capabilities, such as affinity rules, maintenance mode, and power management.
Horizon DRS can be configured with different automation levels, such as fully automated, partially automated, or manual.

Q41. Which pre-requisite should be met before installing the Horizon Connection Server?

The host system must be a vSphere VM with a static IP address.

Use a domain user account with administrator privileges on the Horizon Connection Server.

An SSL server certificate must be installed on the Horizon Connection Server.

Install AD DS and AD LDS Tools on the Horizon Connection Server.

Q42. How do multiple Horizon Connection Server instances in a pod maintain synchronization?

Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server.

Horizon Connection Server instances keep their data in an Oracle database, which works as the central hub.

Horizon Connection Server instances keep their data in a local MySQL DB. The data is synchronized once every 24h.

Horizon Connection Server instances keep their data in an MS SQL database, which works as the central hub.

Q43. How does an administrator enable debug logging for a single user in VMware Dynamic Environment Manager?

Update the FlexEngine registry to DEBUG.

Create an empty FlexDebug.log file in the log folder.

Create an empty FlexDebug.txt file in the log folder.

Configure the FlexEngine GPO to DEBUG.

Q44. Refer to the exhibit.

An administrator is trying to create an automated farm of instant-clone virtual machines using the Add Farm wizard. The administrator cannot proceed beyond the page displayed in the exhibit.
Which of the following could be the reason for the issue?

In the Add Farm wizard, the administrator may not have selected Automated Farm as farm type.

The administrator may not have added an instant clone domain administrator to VMware Horizon.

The administrator did not prepare a RDSH golden image snapshot.

The administrator did not add the RDSH golden image to the correct domain.

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.

Q47. How do multiple Horizon Connection Server instances in a pod maintain synchronization?

Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server.

Horizon Connection Server instances keep their data in an Oracle database, which works as the central hub.

Horizon Connection Server instances keep their data in a local MySQL DB. The data is synchronized once every 24h.

Horizon Connection Server instances keep their data in an MS SQL database, which works as the central hub.

Q49. Which two capabilities are supported by VMware Dynamic Environment Manager Application Profiler?
(Choose two.)

It allows individual user personalization of applications.

It allows creation of application-specific predefined settings.

It allows third-party user personalization of applications.

It analyzes registry and file system location settings for an application.

It allows creation of computer templates.

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.

Q54. An administrator needs to deploy an application to specific users in their instant-clone desktop environment with the following characteristics:
* The application needs to be updated very frequently.
* The application needs to be installed as soon as possible.
* The application is not multi-user aware.
Which solution would meet the requirements?

VMware Horizon Published Application

VMware Dynamic Environment Manager

VMware ThinApp

VMware App Volumes

Explanation
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 volumesare 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.
