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

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]

Answer : A, D

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

Single sign-on (SSO) is a feature that allows users to log in to Horizon Client once and launch remote desktops and applications without being prompted for credentials again. SSO is enabled by default and can be configured in the Global Settings of Horizon Administrator. One of the settings is SSO Timeout, which determines how long the user's credentials are cached before they expire. If the SSO Timeout is too short, users might be frequently asked for credentials when opening additional apps. To resolve this issue, the administrator can increase the SSO Timeout value or set it to -1, which means that no SSO timeout limit is set.Reference:Global Settings for Client Sessions in Horizon Consoleand [VMware Horizon 8.x Professional Course]

Answer : C

One of the possible reasons that the administrator is not seeing the printers within his Horizon Desktop session is that printing is disabled in the Horizon Desktop Pool. Printing is a feature that allows users to print from a remote desktop to any local or network printer available on their client device. Printing can be enabled or disabled for each desktop pool by using the VMware Integrated Printing feature.

VMware Integrated Printing is a feature that supports client printer redirection, location-based printing, and persistent print settings. Client printer redirection enables users to print from a remote desktop to any local or network printer available on their client device. Location-based printing enables users to print to network printers that are physically near their client device. Persistent print settings enable users to retain their print settings across sessions.

To enable or disable printing for a desktop pool, the administrator needs to follow these steps:

In Horizon Console, select Inventory > Desktops.

Select the desktop pool and click Edit.

In the Edit Desktop Pool dialog box, select the VMware Integrated Printing tab.

Select or clear the Enable VMware Integrated Printing check box.

Click OK.

If printing is disabled for a desktop pool, users will not see any printers within their Horizon Desktop session, even if they have installed the VMware Integrated Printing feature in the Horizon Agent and the Horizon Client. Therefore, to resolve this issue, the administrator needs to enable printing for the desktop pool by selecting the Enable VMware Integrated Printing check box.

The other options are not likely to be the reason that the administrator is not seeing the printers within his Horizon Desktop session:

Port TCP 9427 is disabled: This port is used by the VMware Integrated Printing feature for communication between the Horizon Agent and the Horizon Client. If this port is disabled, users might experience printing errors or delays, but they should still see the printers within their Horizon Desktop session.

The VMware Integrated Printing feature is not installed in the Horizon Client: This feature is installed by default in the Horizon Client for Windows, Mac, Linux, Chrome, and HTML Access. If this feature is not installed in the Horizon Client, users might not be able to print from their remote desktops, but they should still see the printers within their Horizon Desktop session.

Port TCP 32111 is disabled: This port is used by ThinPrint for communication between the Horizon Agent and the ThinPrint Client. ThinPrint is a legacy printing feature that has been replaced by VMware Integrated Printing. If this port is disabled, users might experience printing errors or delays with ThinPrint, but they should still see the printers within their Horizon Desktop session if they use VMware Integrated Printing.

Answer : A

Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

Answer : C, D

A cloud implementation of a VDI solution over an on-premises solution is appropriate for the following scenarios:

The organization needs to quickly scale-up in disparate geographical locations. A cloud VDI solution can provide faster provisioning, deployment, and management of virtual desktops and applications across multiple regions and data centers.A cloud VDI solution can also offer better performance, availability, and user experience for remote and mobile workers who need to access their desktops and applications from anywhere and any device12.

The organization has limited CapEx budget. A cloud VDI solution can reduce the upfront capital expenditure (CapEx) required to purchase, install, and maintain the hardware and software infrastructure for a VDI solution. A cloud VDI solution can also lower the operational expenditure (OpEx) by shifting the responsibility of managing, updating, and securing the VDI infrastructure to the cloud provider.A cloud VDI solution can offer flexible and predictable pricing models based on usage, subscription, or consumption13.

The other scenarios are not appropriate for a cloud implementation of a VDI solution over an on-premises solution because:

The organization already has infrastructure to support a VDI. If the organization has already invested in the hardware and software resources to support a VDI solution, it may not be cost-effective or feasible to migrate to a cloud VDI solution.The organization may also have existing policies, processes, and workflows that are tailored to the on-premises VDI solution and may not be compatible with the cloud VDI solution4.

The organization needs to setup high availability and disaster recovery. While a cloud VDI solution can provide high availability and disaster recovery capabilities, it may not be sufficient or reliable for some organizations that have strict requirements for data protection, compliance, and business continuity.An on-premises VDI solution can offer more control, customization, and security over the backup, replication, and restoration of the VDI data and applications in the event of a disaster5.

The organization controls highly confidential data. A cloud VDI solution may pose some risks or challenges for organizations that handle sensitive or regulated data, such as financial, healthcare, or government data. A cloud VDI solution may not meet the compliance standards or regulations that apply to the organization's data. A cloud VDI solution may also expose the organization's data to potential breaches, leaks, or unauthorized access by third parties.An on-premises VDI solution can provide more visibility, governance, and encryption over the organization's data6.

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.
