VMware 2V0-51.23 Practice Test - Questions Answers

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.

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.

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 this problem, 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.

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.

An Automated Desktop Pool using Dedicated Full Clone Virtual Machines best meets the requirements because it ensures end-users always receive the same desktop VM, supports backups with VMware's image-based backup tools, and allows for cloning via the vSphere API on a weekly basis. Full clones are standalone VMs that don't depend on a parent VM after being created, making them suitable for image-based backups and consistent user experience.

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.

In VMware Horizon, the Pre-Launch feature allows for the initiation of applications immediately after user authentication, reducing the launch time of frequently used applications. By editing the application pool settings and enabling the Pre-Launch option, administrators can improve user experience by having critical applications ready as soon as the authentication process is completed.

VMware Horizon's Dynamic Environment Manager (DEM) is designed to provide a consistent and personalized desktop experience for users across different sessions and desktops. DEM manages user profiles and policies dynamically, ensuring that user settings, preferences, and application configurations are consistent no matter which desktop a user connects to, thus meeting the requirement for a uniform desktop experience.

Application Profiler is a tool that analyzes the registry and file system locations where the settings for a particular application are stored, and creates a Flex configuration file for use with Dynamic Environment Manager.Application Profiler is installed using VMware Dynamic Environment Manager Enterprise Setup Wizard and explicitly selecting local drive installation1. This option allows you to install Application Profiler on a separate machine from the Dynamic Environment Manager Agent or Management Console.Alternatively, you can install Application Profiler on the same machine as the Dynamic Environment Manager Agent or Management Console, by selecting network share installation1.

VMware Dynamic Environment Manager Agent and the Application Profiler can be installed on the same machine, but it is not recommended.This is because the Dynamic Environment Manager Agent might interfere with the profiling process by applying settings to the application being profiled1. Therefore, it is best to use a clean system for profiling applications.

Application Profiler is not installed automatically when installing VMware Dynamic Environment Manager FlexEngine or Management Console.FlexEngine is the component that applies the user environment settings during logon, logoff, and session reconnect or disconnect events2.Management Console is the component that allows you to configure and manage the user environment settings2. Neither of these components requires Application Profiler to function.Application Profiler is an optional tool that helps you create Flex configuration files for applications that are not included in the predefined settings library1.Reference:
