質問 # 10
What is the effect of changing any VMware Blast policy that cannot be changed in real time?

• A. Microsoft GPO update rules apply and GPOs are updated manually or by restarting the Horizon Agent.
• B. VMware Tools detects the change and immediately applies the new setting within 480 seconds.
• C. VMware Tools services is restarted by Microsoft GPO Update service.
• D. Horizon Client detects the change and prompts the user to reboot once every 480 seconds.

正解：A

解説：
Explanation
VMware Blast policy settings are stored in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\Config on the remote desktops or RDS hosts that use the VMware Blast display protocol. These settings can be configured by using the VMware Blast ADMX template file (vdm_blast.admx) and applying it through Microsoft Group Policy Object (GPO). Some of these settings can be changed in real time, which means that they take effect immediately after the policy is applied, without requiring a reboot or a reconnection of the Horizon Client. However, some of these settings cannot be changed in real time, which means that they require a reboot or a reconnection of the Horizon Client to take effect.
The effect of changing any VMware Blast policy that cannot be changed in real time is that the Microsoft GPO update rules apply and GPOs are updated manually or by restarting the Horizon Agent. This means that the new policy settings will not be applied until one of the following events occurs:
The Horizon Agent service is restarted on the remote desktop or RDS host. This can be done manually by using the Services console or the command-line tool sc.exe, or automatically by using a scheduled task or a script.
The remote desktop or RDS host is rebooted. This can be done manually by using the Restart option in Windows, or automatically by using a scheduled task or a script.
The Group Policy refresh interval is reached. This is a configurable time interval that determines how often the system checks for and applies new or changed GPOs. By default, this interval is 90 minutes for domain members and 5 minutes for domain controllers, with a random offset of 0 to 30 minutes. This interval can be modified by using the Group Policy refresh interval for computers setting in the ComputerConfiguration\Administrative Templates\System\Group Policy folder of the Group Policy Management Console.
Therefore, to ensure that the VMware Blast policy settings that cannot be changed in real time are applied as soon as possible, it is recommended to restart the Horizon Agent service or reboot the remote desktop or RDS host after applying the policy.

質問 # 11
An administrator has added a supported PCI graphics accelerator to a virtual machine configuration. When the administrator tries to power on the virtual machine, an error is displayed and the virtual machine remains powered off.
Which of the following virtual machine configuration settings needs to be applied to enable the virtual machine to power on?

• A. Reserve all guest memory.
• B. Set Memory Shares to High.
• C. Disable CPU Hot Plug.
• D. Enable Video Card 3D Graphics.

正解：A

解説：
To enable a virtual machine to power on with a PCI graphics accelerator, such as a GPU, attached to it, the administrator needs to reserve all guest memory for that virtual machine. This is because PCI devices require direct memory access (DMA) to function properly, and memory overcommitment can interfere with DMA operations. Reserving all guest memory ensures that no memory swapping or ballooning occurs on the virtual machine, and that the memory address space is contiguous and available for DMA56.
The other options are not required or valid because:
Enabling Video Card 3D Graphics is not necessary for using a PCI graphics accelerator. This option is for using software-accelerated graphics or virtual shared graphics acceleration (vSGA) on a virtual machine7.
Setting Memory Shares to High does not guarantee that all guest memory will be reserved. Memory shares only affect how memory resources are distributed among competing virtual machines when there is memory contention on the host. Memory shares do not prevent memory overcommitment or swapping.
Disabling CPU Hot Plug does not affect the use of a PCI graphics accelerator. CPU Hot Plug allows adding or removing virtual CPUs from a powered-on virtual machine. It has no relation to PCI devices or DMA operations.

質問 # 12
An administrator wants to deploy a RDS farm which can be patched in a rolling process with zero downtime.
Which of the following statements is true in this scenario?

• A. Create a manual RDS desktop farm.
• B. Nothing needs to be done. All RDS farms can be patched in a rolling process with zero downtime.
• C. This cannot be done as updating a Farm always incurs downtime.
• D. Create an instant-clone RDS desktop farm.

正解：D

解説：
Instant clones are a type of virtual machines that are created by cloning a running parent VM in memory, without requiring a full disk copy. This allows for faster provisioning and updating of RDS hosts in a farm.
Instant clones can be patched in a rolling process with zero downtime by using the push-image operation, which replaces the existing instant clones with new ones that have the latest patches applied. The push-image operation can be performed on a per-farm basis or on multiple farms at once. The push-image operation preserves the user sessions and data on the existing instant clones until they are logged off or disconnected, and then deletes them. The new instant clones inherit the same settings and assignments as the old ones.
Therefore, to deploy a RDS farm that can be patched in a rolling process with zero downtime, the administrator should create an instant-clone RDS desktop farm. References: Instant Clones for RDSH in VMware Horizon 7.1 and [VMware Horizon 8.x Professional Course]

質問 # 13
A Horizon administrator has been utilizing Application Profiler from Dynamic Environment Manager to create application-specific user defined settings. These files have grown to 2.3GB in size for a particular user and have negatively impacted the user experience.
What can be done to the configuration to improve the user experience?

• A. Use Deepest Registry Path.
• B. Configure exclusions to filter out unnecessary registry entries.
• C. Configure exclusions to filter out unnecessary folders.
• D. Change the default save path.

正解：C

解説：
Explanation
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.

質問 # 14
Where are exclusions specified for Writable Volumes to prevent App Volumes from persisting specific data between sessions?

• A. json.cfg
• B. config.ini
• C. svservice.log
• D. snapvol.cfg

正解：D

解説：
Writable Volumes are user-specific virtual disks that store user-installed applications, data, and settings. App Volumes is a real-time application delivery system that uses Writable Volumes to deliver applications that are not multi-user aware. However, sometimes it might be necessary to prevent App Volumes from persisting specific data between sessions, such as temporary files, application updates, or registry keys. To do this, administrators can specify exclusions for Writable Volumes in a policy file called snapvol.cfg.
The snapvol.cfg file is a text file that contains policy settings for App Volumes. These settings determine which files and registry keys are captured or excluded by App Volumes. The snapvol.cfg file can be customized by administrators to suit different needs and scenarios. The snapvol.cfg file can be applied to both application packages and Writable Volumes.
To specify exclusions for Writable Volumes, administrators can use the following keywords in the snapvol.cfg file:
exclude_uwv_file: This keyword excludes a file or folder path from being persisted on a Writable Volume. For example, exclude_uwv_file=\Program Files (x86)\Notepad++ excludes the folder location of Notepad++ from being overwritten during an update.
exclude_uwv_reg: This keyword excludes a registry key or value from being persisted on a Writable Volume. For example, exclude_uwv_reg=\REGISTRY\MACHINE\SOFTWARE\Notepad++ excludes the registry location of Notepad++ from being overwritten during an update.
The snapvol.cfg file must be uploaded to the Writable Volume by using the Update Writable Volumes feature in App Volumes Manager. The exclusions will take effect after the user logs off and logs back in to the desktop.
The other options are not valid files for specifying exclusions for Writable Volumes:
config.ini: This file is used to configure the App Volumes agent settings, such as the App Volumes Manager address, the logging level, and the SSL certificate validation.
svservice.log: This file is used to record the App Volumes agent log messages, such as the agent status, the package attachment, and the error messages.
json.cfg: This file does not exist in App Volumes.

質問 # 16
What are two best practices for Windows Golden Image Optimization? (Choose two.)

• A. Turn on automatic Windows maintenance (scheduled tasks).
• B. Disable unnecessary services.
• C. Disable power options.
• D. Turn on automatic Windows Updates.
• E. Activate Windows OS paging.

正解：B、C

解説：
Windows golden image optimization is the process of reducing the size and improving the performance of the Windows OS image that is used as the base for the desktop pools. Some of the best practices for Windows golden image optimization are:
Disable unnecessary services: Services that are not required for the desktop functionality or user experience should be disabled to reduce the resource consumption and potential security risks. For example, services such as Windows Search, Windows Defender, Windows Update, and Superfetch can be disabled for better performance and stability.
Disable power options: Power options such as hibernation and sleep mode should be disabled to free up disk space and avoid potential issues with the desktop state. Hibernation can consume a large amount of disk space by creating a hiberfil.sys file that stores the system memory contents when the desktop is powered off. Sleep mode can cause problems with network connectivity and user sessions when the desktop is resumed from a low-power state.
Other best practices for Windows golden image optimization include:
Activate Windows OS paging: Paging is a mechanism that allows the OS to use a portion of the disk as virtual memory when the physical memory is insufficient. Paging can improve the performance and stability of the desktops by preventing out-of-memory errors and reducing memory contention.
However, paging can also increase disk I/O and wear, so it should be configured with caution and monitored regularly.
Turn off automatic Windows maintenance (scheduled tasks): Automatic Windows maintenance is a feature that runs various tasks such as disk defragmentation, disk cleanup, security scanning, and system diagnostics in the background. These tasks can consume a lot of CPU, memory, and disk resources and interfere with the user experience and desktop performance. Therefore, it is recommended to turn off automatic Windows maintenance and run these tasks manually or on a scheduled basis when the desktops are not in use.
Turn off automatic Windows Updates: Automatic Windows Updates is a feature that downloads and installs updates for the OS and other Microsoft products in the background. These updates can consume bandwidth, disk space, and CPU resources and cause compatibility issues with some applications or drivers. Therefore, it is recommended to turn off automatic Windows Updates and manage the updates manually or through a centralized tool such as VMware Update Manager or Microsoft WSUS.

質問 # 19
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?

• A. Administrator provides this information in the Horizon Agent Installation Wizard on the master image.
• B. Administrator provides this information in the "Add Pool" creation wizard.
• C. Horizon Agent retrieves this information from an DNS SRV record.
• D. Horizon Agent queries VMware Tools for a Guestlnfo Variable during the cloning process.

正解：D

解説：
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.

質問 # 21
A user is complaining that each time they logon they need to change the settings for the e-mail client.
Which three options can an administrator deploy to make sure the user's settings are being saved? (Choose three.)

• A. Flexible profiles
• B. VMware Dynamic Environment Manager
• C. VMware App Volumes Writeable Volumes
• D. Persona Management
• E. Roaming Profiles

正解：B、C、D

解説：
Explanation
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.

質問 # 24
To reduce the risk of users downloading malware to the corporate network, an administrator wants to allow end-users to open only intranet websites inside their virtual desktop. Additionally, the administrator wants to configure all other URLs to automatically open in a browser on the end-user's client machine.
Which steps should the administrator take to meet the requirements? (Choose two.)

• A. Enable secure website settings in the Global Settings Security menu.
• B. Enable the URL Content Redirection feature on the desktop pool settings.
• C. Enable the URL Content Redirection feature in Horizon Agent.
• D. Configure group policy settings to indicate how Horizon Agent redirects the URL
• E. Disable the Allow External Website feature in Horizon Agent.

正解：C、D

解説：
Explanation
The URL Content Redirection feature allows administrators to configure specific URLs to open on the client machine or in a remote desktop or published application. This can help reduce the risk of users downloading malware to the corporate network, as well as improve the user experience and performance of certain web applications.
To meet the requirements of the scenario, the administrator needs to enable the URL Content Redirection feature in Horizon Agent when installing or upgrading it on the instant-clone desktops. This will allow Horizon Agent to send or receive URLs from Horizon Client, depending on the redirection direction. The administrator also needs to configure group policy settings to indicate how Horizon Agent redirects the URL.
Specifically, the administrator needs to enable agent-to-client redirection, which means that Horizon Agent sends the URL to Horizon Client, which opens the default application for the protocol in the URL on the client machine. The administrator also needs to specify which URLs are redirected from a remote desktop to a client, and which URLs are not redirected. In this case, the administrator needs to configure a whitelist of intranet websites that are allowed to open inside the virtual desktop, and a blacklist of all other websites that are automatically redirected to a browser on the client machine.
The other options are not relevant or sufficient for meeting the requirements. Disabling the Allow External Website feature in Horizon Agent will prevent users from accessing any external websites from their virtual desktops, which might not be desirable or practical. Enabling secure website settings in the Global Settings Security menu will not affect how URLs are redirected, but only how secure connections are establishedbetween Horizon components. Enabling the URL Content Redirection feature on the desktop pool settings will not work unless it is also enabled in Horizon Agent and configured with group policy settings.

質問 # 25
The administrator of Windows 10 desktops in a VMware Horizon environment needs to build a new Windows
10 desktop pool. This new pool will be dedicated to training and onboarding new employees. The administrator has created a shortcut on a test machine, which has successfully opened the web browser to the on-boarding applications. After deploying the new desktop pool across the company, the administrator notices that the shortcut placed on desktops is not available to any other user connecting to the desktop pool.
Which two options are available for the administrator to make this shortcut available to all desktop pool users, while minimizing ongoing administrative effort, before updating the desktop pool golden image? (Choose two.)

• A. Copy the shortcut to the Windows Default Domain Controller Policy.
• B. Copy the shortcut during user provisioning to a non-writeable App Volume.
• C. Copy the shortcut to c:\users\Public\Desktop.
• D. Configure a Shortcut with DEM (Dynamic Environment Manager).
• E. Configure a Shortcut with Horizon View Client.

正解：C、D

解説：
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.

An administrator configured a virtual machine to use an NVIDIA card but the virtual machine is not starting up.
What could be the cause of the issue? (Choose two.)

• A. Not all CPU has been reserved on the VM.
• B. No suitable host could be found.
• C. Not all memory has been reserved on the VM.
• D. 3D graphics cannot be used with local storage.
• E. The Desktop Pool doesn't support 3D cards.

正解：B、C

解説：
When configuring a virtual machine to use an NVIDIA graphics card, issues such as the VM not starting can occur if there is no suitable host available that meets the requirements for 3D graphics, or if not all memory required by the 3D graphics card has been reserved for the VM. Ensuring that the host has the necessary 3D graphics capabilities and that the VM is configured with reserved memory can resolve these issues.

An administrator is tasked with creating an instant clone pool for their sales department. During the creation of the pool the administrator saw that there is no golden image available, as seen in the exhibit.
Which two actions can an administrator take so that the golden image is showing up in the Golden Image selection window? (Choose two.)

• A. Refresh the Select Golden Image view and select the Golden Image.
• B. Login to the vSphere Client, select the Golden Image virtual machine and delete all snapshots.
• C. Login to the vSphere Client, select the Golden Image virtual machine and clone it to a new virtual machine.
• D. Login to the vSphere Client, select the Golden Image virtual machine and create a snapshot
• E. Login to the vSphere Client, select the Golden Image virtual machine and convert it to a template.

正解：D、E

解説：
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.

Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server. AD LDS is a Lightweight Directory Access Protocol (LDAP) directory service that provides flexible support for directory-enabled applications, without the dependencies that are required for Active Directory Domain Services (AD DS). AD LDS provides much of the same functionality as AD DS, but it does not require the deployment of domains or domain controllers. In a Horizon environment, each Connection Server instance has a copy of the AD LDS database and replicates changes to other Connection Server instances in the same pod. This ensures that the Connection Server instances have consistent and up-to-date information about the Horizon resources and user sessions12 References:

Drag and drop the TLS Configuration steps on the left into the correct sequential order on the right.

正解：

解説：

Explanation:
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.

An administrator needs to enable Session Collaboration in the VMware Horizon environment. What will be used as a requirement to enable Session Collaboration?

• A. dedicated Instant Clone pool
• B. BLAST protocol
• C. floating Instant Clone pool
• D. PCoIP protocol

正解：B

解説：
Collaboration is a feature that allows users to invite other users to join an existing Windows or Linux remote desktop session with both screen sharing and audio out features enabled. A remote desktop session that is shared in this way is called a collaborative session. The user that shares a session with another user is called the session owner, and the user that joins a shared session is called a session collaborator. A Horizon administrator must enable the Session Collaboration feature for the desktop pool or farm that contains the remote desktops that support collaboration.
One of the requirements to enable Session Collaboration is to use the VMware Blast display protocol for the remote desktops. VMware Blast is a protocol that provides high-performance, high-quality graphics and multimedia delivery over LAN or WAN networks. VMware Blast supports Session Collaboration by allowing multiple users to view and interact with the same remote desktop session simultaneously. Other display protocols, such as PCoIP or RDP, do not support Session Collaboration and will not allow users to share or join collaborative sessions.
Therefore, to enable Session Collaboration in the VMware Horizon environment, the administrator needs to use the BLAST protocol as a requirement. References: Configuring Session Collaboration, Sharing Remote Desktop Sessions, and [VMware Horizon 8.x Professional Course]

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

• A. Update the FlexEngine registry to DEBUG.
• B. Configure the FlexEngine GPO to DEBUG.
• C. Create an empty FlexDebug.txt file in the log folder.
• D. Create an empty FlexDebug.log file in the log folder.

正解：C

解説：
Explanation
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.
