• Question 41:

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

  A. floating Instant Clone pool

  B. dedicated Instant Clone pool

  C. PCoIP protocol

  D. BLAST protocol

  Correct Answer: D

  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 arequirement.

• Question 42:

  While creating a new Instant Clone Desktop Pool, an administrator does not see a particular Windows 10 VM available or listed as an option for use as the golden image. Which step must the administrator perform, prior to creating this new desktop pool?

  A. Validate the Golden Image with VMware Skyline Health.

  B. Install VMware Dynamic Environment Manager Agent.

  C. Take a Snapshot of the VM that is the golden image.

  D. Configure Advanced parameters of VMware Tools for Horizon of this VM.

  Correct Answer: C

  To create an instant-clone desktop pool, you must first create a golden image virtual machine and take a snapshot of it in a powered-down state. This snapshot provides the base image for the clones. You cannot create an instant-clone desktop pool from a VM template or a powered-on VM. Therefore, the administrator must take a snapshot of the VM that is the golden image before creating the new desktop pool.

• Question 43:

  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?

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

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

  C. The administrator did not prepare a RDSH golden image snapshot.

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

  Correct Answer: B

  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. References: Configuring an Instant Clone Domain

• Question 44:

  Which three steps are required to entitle user and groups to pools? (Choose three.)

  A. Run the Active Directory entitlement script in the golden master, when preparing if for the pool.

  B. 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.

  C. During the Pool creation the desired Active Directory OU for the VMs will be specified. This will automatically add the preconfigured associated user group to the Horizon entitlements.

  D. Navigate to Inventory > Desktops > check mark a pool > click on Add Entitlement.

  E. 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.

  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.

• Question 45:

  An IT support center has been tasked with helping with Horizon desktop user issues.

  What is the minimal level of Horizon Console access they would need to perform this action?

  A. Help Desk Administrators

  B. Local Administrators

  C. Global Help Desk Administrators

  D. Inventory Administrators

  E. Administrators

  Correct Answer: A

  The minimal level of Horizon Console access that the IT support center would need to help with Horizon desktop user issues is the Help Desk Administrators role. This role allows the IT support center to view and troubleshoot user sessions,

  reset user passwords, send messages to users, and perform other help desk tasks. The Help Desk Administrators role can be assigned to users or groups on any access group that contains the desktop pools or farms that the IT support

  center needs to support. The other options are not the minimal level of Horizon Console access for this scenario:

  Local Administrators: This role allows full administration rights on a specific access group and its sub-access groups. This role can perform all the tasks of the Help Desk Administrators role, as well as create, edit, and delete desktop pools,

  farms, applications, entitlements, and other objects. This role is more than what the IT support center needs to help with user issues.

  Global Help Desk Administrators: This role allows full administration rights on all access groups in the Horizon environment. This role can perform all the tasks of the Local Administrators role, as well as create, edit, and delete access groups

  and global entitlements. This role is more than what the IT support center needs to help with user issues.

  Inventory Administrators: This role allows limited administration rights on a specific access group and its sub-access groups. This role can view and manage desktop pools, farms, applications, entitlements, and other objects, but cannot

  create or delete them. This role can also perform some help desk tasks, such as viewing user sessions and sending messages to users, but cannot reset user passwords or troubleshoot sessions. This role is not sufficient for what the IT

  support center needs to help with user issues.

  Administrators: This role allows full administration rights on all access groups in the Horizon environment, as well as global settings, licensing, roles and permissions, events configuration, and other system-wide settings. This role can perform

  all the tasks of theother roles, as well as configure and manage the Horizon infrastructure. This role is more than what the IT support center needs to help with user issues.

• Question 46:

  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. VMware App Volumes Writeable Volumes

  B. Roaming Profiles

  C. Persona Management

  D. VMware Dynamic Environment Manager

  E. Flexible profiles

  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.

• Question 47:

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

  A. Activate Windows OS paging.

  B. Turn on automatic Windows maintenance (scheduled tasks).

  C. Turn on automatic Windows Updates.

  D. Disable unnecessary services.

  E. Disable power options.

  Correct Answer: DE

  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 CPUresources 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.

• Question 48:

  Refer to the exhibit.

  

  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. Login to the vSphere Client, select the Golden Image virtual machine and delete all snapshots.

  B. Login to the vSphere Client, select the Golden Image virtual machine and create a snapshot

  C. Refresh the Select Golden Image view and select the Golden Image.

  D. Login to the vSphere Client, select the Golden Image virtual machine and clone it to a new virtual machine.

  E. Login to the vSphere Client, select the Golden Image virtual machine and convert it to a template.

  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.

• Question 49:

  An administrator is creating an instant clone desktop pool and needs to enable NVIDIA Grid 3D Rendering. NVIDIA GRID vGPU and drivers are installed on the physical ESXi hosts.

  In Horizon Console, when creating an instant-clone pool, the NVIDIA GRID vGPU option is not available in the 3D Render field.

  Which two of the following could be the reason for the issue? (Choose two.)

  A. Horizon 8 does not have an explicit 3D renderer option for instant clone. Select Manage Using vSphere Client in the 3D Render field. Instant-clones inherit the settings configured in the vSphere Client for the golden image.

  B. In Horizon Console, when an instant-clone pool is created, the golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU.

  C. The administrator has selected Shared when editing the Host Graphics Settings for the ESXi host in the vCenter Server.

  D. Instant-clone pools do not support NVIDIA GRID vGPU.

  E. The administrator has selected Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server.

  Correct Answer: AB

  To enable an instant-clone pool to use NVIDIA GRID vGPU, the administrator needs to do the following:

  Install NVIDIA GRID vGPU in the physical ESXi hosts and select Shared Direct in the Host Graphics Settings12.

  Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use12.

  Take a snapshot of the golden image12.

  In Horizon Console, when creating an instant-clone pool, select Manage Using vSphere Client in the 3D Render field. Instant-clones inherit the settings configured in the vSphere Client for the golden image12.

  Therefore, the possible reasons for the issue are:

  The administrator has selected Shared instead of Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server. This option is for vSGA, not vGPU3.

  The golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU. The administrator needs to verify that the correct vGPU profile is selected and that the NVIDIA drivers are installed in the

  golden image4.

  The other options are not valid because:

  Horizon 8 does have an explicit 3D renderer option for instant clone, but it is Manage Using vSphere Client, not NVIDIA GRID vGPU12. Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are

  properly configured12.

• Question 50:

  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?

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

  B. 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.

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

  D. 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.

  Correct Answer: B

  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]
