VMware Horizon 8.x Professional 2V0-51.23 Exam Questions

Answer : D

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

Answer : B, D, F

A golden image must have a current snapshot to be used for cloning, and having multiple active snapshots can cause confusion and issues in the provisioning process. Additionally, selecting the correct Guest OS version is crucial for compatibility and optimal performance. These factors must be correctly configured for a VM to appear in the list of available golden images for provisioning.

Answer : D

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 volumes are 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.

Answer : B, E

If the Horizon Console does not display the health status of configured Unified Access Gateways (UAGs), it could be due to improper firewall configuration blocking traffic on port 443, which is essential for secure communication. Additionally, a discrepancy between the system name in UAG and the name entered in the Horizon Console can also prevent the console from correctly retrieving and displaying the UAG's health status.

Answer : A

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.

Answer : A

To enable the Senior Administrator's team, which is part of the 'Horizon View Operators' AD group, to connect to vCenter and update the golden image, the Senior Administrator needs to assign the appropriate permissions in the vSphere Client. By adding the group to the vCenter Server with the necessary roles and privileges, members of the 'Horizon View Operators' group will be able to access and modify the VMs required for maintaining the desktop pools in the VMware Horizon environment.

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.
