Correct Answer: D

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.

Correct Answer: ACE

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.

Correct Answer: AC

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 andup 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.

Correct Answer: D

VMware Horizon Cloud on Microsoft Azure is the only deployment solution that meets all the requirements. VMware Horizon Cloud on Microsoft Azure supports Windows 10 Enterprise multi-session desktops, which are a new Remote Desktop Session Host exclusive to Azure Virtual Desktop on Azure1. It also supports App Volumes, which is a real-time application delivery system that enables IT to instantly provision applications to users or desktops. VMware Horizon Cloud on Microsoft Azure supports centralized brokering, which means that the Horizon Cloud Service acts as a single point of entry for end users to access their virtual desktops and applications. VMware Horizon Cloud on Microsoft Azure also supports automatic routing of end-users to the most appropriate virtual workspace, using the Universal Broker feature. Universal Broker is a cloud-based brokering service that provides a unified user experience across multiple Horizon pods and clouds. VMware vSphere Desktop Edition does not support Windows 10 Enterprise multi-session desktops, as they are only available on Azure Virtual Desktop1. VMware Workspace ONE Unified Endpoint Management does not support App Volumes, as it is a different solution for managing devices and applications. VMware Horizon On-Premises does not support automatic routing of end-users to the most appropriate virtual workspace, as it requires manual configuration of load balancing and global entitlements.

Correct Answer: BE

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.

Correct Answer: ACD

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 thisproblem, 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.

Correct Answer: BDE

To entitle users and groups to pools, you need to perform the following steps: During pool creation in the entitlement pane, click on add, search for users and groups in the Active Directory, continue and finish the pool creation. This option allows you to entitle users and groups to a desktop or application pool at the same time as you create the pool3. Navigate to Inventory > Desktops > check mark a pool > click on Add Entitlement. This option allows you to add entitlements to an existing desktop or application pool after you create the pool4. 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. This option allows you to review and manage the entitlements for users and groups from a single location5. The other options are not required or valid for entitling users and groups to pools. Running the Active Directory entitlement script in the golden master is not necessary as Horizon 8 automatically synchronizes with Active Directory domains that are configured in Horizon Console6. Specifying the desired Active Directory OU for the VMs during pool creation does not automatically add the preconfigured associated user group to the Horizon entitlements as you still need to select the users or groups from the search results7.

Correct Answer: A

To improve the user experience when using Application Profiler from Dynamic Environment Manager to create application-specific user defined settings, the administrator can configure exclusions to filter out unnecessary folders and registry entries. Exclusions are rules that specify which file system or registry locations are not included in the Flex configuration file. Exclusions can reduce the size of the Flex configuration file and the profile archive, and improve the performance of the application profiling and synchronization processes12. The other options are not valid or effective because: Changing the default save path does not affect the size or content of the Flex configuration file or the profile archive. It only changes where the files are stored on the local machine3. Using Deepest Registry Path does not reduce the size of the Flex configuration file or the profile archive. It only changes how the registry locations are displayed in the Application Profiler interface4. There is no such thing as Cloud Entitlements in Dynamic Environment Manager. The correct term is Global Entitlements, which are used in Cloud Pod Architecture to entitle users to desktops or applications across multiple pods5.

Correct Answer: BD

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.

Correct Answer: ABF

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.

Correct Answer: B

To populate logon segment information in the Horizon Helpdesk Tool, the Horizon administrator must enable the timing profiler on all Connection Servers. This is done by executing the command vdmadmin -I -timingProfiler -enable . The timing profiler collects detailed timing data about the logon process, which is then displayed in the Horizon Helpdesk Tool, allowing administrators to troubleshoot and improve logon times.

Correct Answer: A

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.
