VMware 2V0-51.23 VMware Horizon 8.x Professional Exam Practice Test

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.Reference:App Volumes Architectureand [VMware Horizon 8.x Professional Course]

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 established between 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.Reference:Configuring URL Content Redirectionand [VMware Horizon 8.x Professional Course]

Answer : A

Roles and permissions are a way of controlling the access and actions of administrators and users in Horizon. By default, Horizon provides two predefined roles: Administrators and Read Only Administrators. However, a high-level administrator can create custom roles with specific privileges to suit different needs and scenarios. To create a custom role, the administrator needs to follow these steps:

In the navigation pane under the Settings section, click on Administrators > Roles and Permissions.

In the Roles and Permissions page, click on Add.

In the Add Role pane, enter a name for the role in the Role Name text box.

In the Privileges section, select the checkboxes for the privileges that you want to assign to the role. You can expand or collapse the categories to view or hide the sub-privileges. You can also use the Select All or Deselect All buttons to select or clear all the privileges in a category.

Click on Save to create the custom role.

The custom role will appear in the Roles and Permissions page, where you can edit or delete it as needed. You can also assign the custom role to users or groups in the Users and Groups page.Reference: [Create Custom Roles] and [VMware Horizon 8.x Professional Course]

VMware vSAN is a storage product that allows the pooling of resources to create datastores in a software defined datacenter. VMware vSAN is a hyper-converged infrastructure solution that integrates compute, storage, and networking resources on industry-standard x86 servers. VMware vSAN aggregates local or direct-attached data storage devices to create a single storage pool shared across all hosts in the vSAN cluster. VMware vSAN enables you to provision and manage storage from the VMware vSphere Web Client or the VMware vCenter Server Appliance Shell.VMware vSAN provides several benefits, such as lower total cost of ownership, simplified management, high performance, scalability, and availability12.Reference:=1: VMware Horizon 8 Documentation:VMware vSAN Overview2: VMware Horizon 8 Documentation:Benefits of Using VMware vSAN with Horizon 8

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.Reference:=3: VMware Horizon 8 Documentation:Add Entitlements During Pool Creation4: VMware Horizon 8 Documentation:Add Entitlements After Pool Creation5: VMware Horizon 8 Documentation:Review and Manage Entitlements6: VMware Horizon 8 Documentation:Active Directory Requirements for Horizon Connection Server7: VMware Horizon 8 Documentation:Create an Automated Desktop Pool

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.Reference: [Optimizing Your VMware Horizon View 7.x Golden Image] and [VMware Horizon 8.x Professional Course]
