VMware 2V0-51.23 Online Questions & Answers

• Question 1:

  An administrator is tasked with configuring VMware Integrated Printing. They enabled the VMware Integrated Printing feature during the installation of the Horizon Agent in the golden image, and created a Test Desktop Pool. On a physical end-point where the Horizon Client already is installed, the administrator added multiple network printers which are working perfectly. They test the configuration by connecting to the Horizon Desktop with the Horizon Client, unfortunately they do not see the printers within their Horizon Desktop.

  What could be the reason that the administrator is not seeing the printers within his Horizon Desktop session?

  A. Port TCP 9427 is disabled.
  B. The VMware Integrated Printing feature is not installed in the Horizon Client.
  C. Printing is disabled in the Horizon Desktop Pool.
  D. Port TCP 32111 is disabled.
  C. Printing is disabled in the Horizon Desktop Pool.

  ---

  Explanation/Reference:

  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.

• Question 2:

  Which pre-requisite should be met before installing the Horizon Connection Server?

  A. The host system must be a vSphere VM with a static IP address.
  B. Use a domain user account with administrator privileges on the Horizon Connection Server.
  C. An SSL server certificate must be installed on the Horizon Connection Server.
  D. Install AD DS and AD LDS Tools on the Horizon Connection Server.
  B. Use a domain user account with administrator privileges on the Horizon Connection Server.

  ---

  Explanation/Reference:

  One of the prerequisites for installing the Horizon Connection Server is to use a domain user account with administrator privileges on the system. This is because the installer needs to access and modify certain system files and registry settings, as well as create and configure the VMware Horizon View services. The installer also authorizes an Administrators account that has full administration rights for the Horizon environment, including the right to install replicated Connection Server instances. The other options are not prerequisites for installing the Horizon Connection Server. The host system can be a physical or virtual machine, but it must have an IP address that does not change. An SSL server certificate is not required for the initial installation, but it is recommended to replace the default self-signed certificate with a valid certificate from a trusted CA after the installation. AD DS and AD LDS Tools are not required for installing the Horizon Connection Server, but they can be useful for troubleshooting and managing the ADAMdatabase that stores the Horizon configuration data.

• Question 3:

  An administrator has added a supported PCI graphics accelerator to a virtual machine configuration. When the administrator tries to power on the virtual machine, an error is displayed and the virtual machine remains powered off.

  Which of the following virtual machine configuration settings needs to be applied to enable the virtual machine to power on?

  A. Enable Video Card 3D Graphics.
  B. Reserve all guest memory.
  C. Set Memory Shares to High.
  D. Disable CPU Hot Plug.
  B. Reserve all guest memory.

  ---

  Explanation/Reference:

  To enable a virtual machine to power on with a PCI graphics accelerator, such as a GPU, attached to it, the administrator needs to reserve all guest memory for that virtual machine. This is because PCI devices require direct memory access (DMA) to function properly, and memory overcommitment can interfere with DMA operations. Reserving all guest memory ensures that no memory swapping or ballooning occurs on the virtual machine, and that the memory address space is contiguous and available for DMA56. The other options are not required or valid because: Enabling Video Card 3D Graphics is not necessary for using a PCI graphics accelerator. This option is for using software-accelerated graphics or virtual shared graphics acceleration (vSGA) on a virtual machine7. Setting Memory Shares to High does not guarantee that all guest memory will be reserved. Memory shares only affect how memory resources are distributed amongcompeting virtual machines when there is memory contention on the host. Memory shares do not prevent memory overcommitment or swapping. Disabling CPU Hot Plug does not affect the use of a PCI graphics accelerator. CPU Hot Plug allows adding or removing virtual CPUs from a powered-on virtual machine. It has no relation to PCI devices or DMA operations.

• Question 4:

  End-users are complaining that they are frequently being asked for credentials when opening additional apps. Which step should the administrator take to resolve the issue?

  A. Configure SSO Timeout by modifying the Global Settings in Horizon Administrator.
  B. Configure a time limit by modifying the Horizon GPO.
  C. Configure Desktop Timeout by modifying the Pool Settings in Horizon Administrator.
  D. Configure Session Timeout by modifying the Client Settings in Horizon Client.
  A. Configure SSO Timeout by modifying the Global Settings in Horizon Administrator.

  ---

  Explanation/Reference:

  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.

• Question 5:

  An administrator is tasked with creating a new pool of desktops with hardware-accelerated graphics with vMotion support. Which graphic acceleration types can the administrator choose to meet the requirement?

  A. Virtual Shared 3D rendering
  B. Virtual Shared Pass-through Graphics Acceleration
  C. Virtual Shared Direct access 3D
  D. Virtual Dedicated Graphics Acceleration
  B. Virtual Shared Pass-through Graphics Acceleration

• Question 6:

  Where are exclusions specified for Writable Volumes to prevent App Volumes from persisting specific data between sessions?

  A. snapvol.cfg
  B. config.ini
  C. svservice.log
  D. json.cfg
  A. snapvol.cfg

  ---

  Explanation/Reference:

  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 databetween 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. References: Writable Volume

• Question 7:

  To reduce the risk of users downloading malware to the corporate network, an administrator wants to allow end-users to open only intranet websites inside their virtual desktop. Additionally, the administrator wants to configure all other URLs to automatically open in a browser on the end-user's client machine.

  Which steps should the administrator take to meet the requirements? (Choose two.)

  A. Enable the URL Content Redirection feature in Horizon Agent.
  B. Disable the Allow External Website feature in Horizon Agent.
  C. Enable secure website settings in the Global Settings Security menu.
  D. Configure group policy settings to indicate how Horizon Agent redirects the URL
  E. Enable the URL Content Redirection feature on the desktop pool settings.
  A. Enable the URL Content Redirection feature in Horizon Agent.
  D. Configure group policy settings to indicate how Horizon Agent redirects the URL

  ---

  Explanation/Reference:

  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 establishedbetween 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.

• Question 8:

  How do multiple Horizon Connection Server instances in a pod maintain synchronization?

  A. Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server.
  B. Horizon Connection Server instances keep their data in an Oracle database, which works as the central hub.
  C. Horizon Connection Server instances keep their data in a local MySQL DB. The data is synchronized once every 24h.
  D. Horizon Connection Server instances keep their data in an MS SQL database, which works as the central hub.
  A. Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server.

  ---

  Explanation/Reference:

  Horizon Connection Server instances keep their data in an AD LDS database, which is automatically synchronized between the Connection Server. AD LDS is a Lightweight Directory Access Protocol (LDAP) directory service that provides flexible support for directory-enabled applications, without the dependencies that are required for Active Directory Domain Services (AD DS). AD LDS provides much of the same functionality as AD DS, but it does not require the deployment of domains or domain controllers. In a Horizon environment, each Connection Server instance has a copy of the AD LDS database and replicates changes to other Connection Server instances in the same pod. This ensures that the Connection Server instances have consistent and up-to- date information about the Horizon resources and user sessions12 References: Configuring Horizon Connection Server1 Understanding VMware Horizon Services2

• Question 9:

  Which three VMware Horizon based resources does Unified Access Gateway (UAG) provide access to? (Choose three.)

  A. virtual desktops
  B. RDSH-based applications
  C. physical Windows machines
  D. IOT devices
  E. thin clients
  A. virtual desktops
  B. RDSH-based applications
  C. physical Windows machines

  ---

  Explanation/Reference:

  Unified Access Gateway (UAG) is a secure gateway appliance that provides access to VMware Horizon based resources such as virtual desktops, RDSH-based applications, and physical Windows machines. UAG supports multiple authentication methods and protocols, such as SAML, OAuth, and RADIUS, to provide secure access to end users from any device and location. UAG also provides edge services such as load balancing, high availability, and firewall rules to optimize the performance and availability of Horizon based resources12.
